    MANUFACTURING ET AL.
    (AC 38480)
    Alvord, Sheldon and Mullins, Js.
    Syllabus
    The plaintiff appealed to this court from the decision of the Workers’ Com-
    pensation Review Board affirming the decision of the Workers’ Compen-
    sation Commissioner that the plaintiff was not entitled to certain
    temporary partial or total disability benefits. The plaintiff, who had
    undergone two prior surgeries on his left shoulder, claimed that he
    injured that shoulder during his employment with the defendant manu-
    facturer, E Co., when he moved a barrel and felt a pop in the shoulder.
    Thereafter, an independent surgeon, S, who had been selected by E Co.,
    examined the plaintiff and concurred with the determination by the
    plaintiff’s treating physician, O, that the plaintiff was suffering from a
    fracture and lesions in his left shoulder. S, who did not have the plaintiff’s
    entire prior medical history when he examined the plaintiff, determined
    that the fracture and lesions were not caused in the incident in which
    the plaintiff moved the barrel, which he determined caused nothing more
    than a temporary strain of the plaintiff’s left shoulder. After obtaining
    additional prior medical records of the plaintiff, S affirmed that finding
    in a subsequent addendum to his medical report. After O examined the
    plaintiff and recommended that a third surgery be performed on the
    plaintiff’s shoulder, the commissioner ordered the plaintiff to undergo
    an examination by B, a surgeon chosen by the commissioner. B deter-
    mined that the fracture and lesions in the plaintiff’s left shoulder were
    attributed to the barrel incident. The commissioner found that S’s opin-
    ion was more persuasive than those of O and B, and concluded, inter
    alia, that the plaintiff had injured his left shoulder in the course of his
    employment for which he was entitled to receive certain temporary
    total disability benefits, but that the fracture and lesions were not caused
    by the barrel incident. The commissioner, thus, denied the plaintiff’s
    claim for certain temporary partial disability benefits. Held:
    1. The board properly determined that the commissioner’s findings concern-
    ing the cause and extent of the plaintiff’s disability were supported by
    sufficient underlying facts and that the inferences drawn from those
    facts were reasonable and legally permissible:
    a. The board did not err in finding that S provided a reasonable basis
    for his opinion, which was supported by sufficient subordinate facts as
    to constitute competent medical evidence on which the commissioner
    properly could rely in making his findings; S physically examined the
    plaintiff, performed a neurological assessment of him, reviewed medical
    records from O and twice reviewed additional medical records that he
    did not have at the time he examined the plaintiff, and S’s written
    opinion was not so contradicted by his deposition testimony as to
    render it speculative or conjectural.
    b. The plaintiff’s claim that, because the medical examiners did not
    testify before the commissioner, this court should depart from the
    degree of deference usually afforded to the commissioner’s credibility
    determinations and determine the appropriate weight to afford the
    opinions of the medical experts was unavailing; there was no reason
    for this court to give less deference to the commissioner’s credibility
    determinations where, as here, the commissioner was not presented
    with only written reports of nontestifying witnesses, and his credibility
    determinations and findings were clearly influenced by the plaintiff’s
    live testimony that he never engaged in weightlifting or other forms of
    physical exercise, which was directly contradicted by O’s medical notes
    and statements from the plaintiff’s former coworkers.
    2. The board did not abuse its discretion in not remanding the matter to
    the commissioner for an articulation as to why the commissioner, in
    rendering his decision, disregarded the opinion of B, the medical exam-
    iner chosen by the commissioner to examine the plaintiff; the board,
    guided by the state regulation (§ 31-301-3) that governs the requisite
    content of a commissioner’s decision, determined that the commission-
    er’s decision complied with the standard for decisions that do not rely
    on the opinion of a medical examiner chosen by the commissioner, and
    this court deferred to the board’s interpretation and construction of its
    own regulation.

    Opinion
    SHELDON, J. The plaintiff, Louis Sanchez, appeals
    from the decision of the Workers’ Compensation
    Review Board (board) affirming the decision of the
    Workers’ Compensation Commissioner for the Sixth
    District (commissioner), who dismissed, in part, his
    claim for workers’ compensation benefits pursuant to
    General Statutes §§ 31-307 and 31-308 (a). On appeal,
    the plaintiff claims that the board erred (1) in affirming
    the commissioner’s decision that the plaintiff was not
    entitled to temporary partial or temporary total disabil-
    ity benefits from August, 2013 to July, 2014, because
    the commissioner’s finding as to the nature and extent
    of the plaintiff’s workplace injury was not supported
    by sufficient subordinate facts; and (2) in not remanding
    this case to the commissioner with instructions that he
    articulate why, in reaching his decision, he disregarded
    the opinion of his own medical examiner as to the
    nature and extent of the plaintiff’s injury. We affirm the
    decision of the board.
    The following facts and procedural history are rele-
    vant to this appeal. In 1992, the plaintiff was hired by
    Celus Fasteners, a Massachusetts manufacturer, where
    he worked for approximately sixteen years making riv-
    ets. When Celus Fasteners went bankrupt, the plaintiff
    took a job with Metz Personnel (Metz), also in Massa-
    chusetts, where he worked as a laminator. On July 23,
    2008, while working for Metz, the plaintiff tripped and
    fell, landing on his left shoulder. Following his fall,
    the plaintiff began to experience sharp pains in his
    shoulder. Although the plaintiff was given a cortisone
    injection for his shoulder injury and underwent a course
    of physical therapy, his shoulder pain persisted for sev-
    eral months. Thus, in March, 2009, the plaintiff con-
    sulted with an orthopedic surgeon, Dr. Ergin,1 about the
    advisability of undergoing surgery on his left shoulder
    joint. After examining the plaintiff, however, Ergin con-
    cluded that surgery on the plaintiff’s left shoulder joint
    was unnecessary. Instead, Ergin gave the plaintiff two
    additional cortisone injections and instructed him to
    seek a second opinion if he wanted to pursue surgery.
    In accordance with Ergin’s instructions, the plaintiff
    consulted with and was examined by James D. O’Hol-
    leran, an orthopedic surgeon. After reviewing a mag-
    netic resonance imaging (MRI) scan of the plaintiff’s
    shoulder, O’Holleran opined that the plaintiff was suf-
    fering from a torn rotator cuff, AC joint arthrosis, and
    a superior labral tear in his left shoulder, for which
    he recommended that the plaintiff undergo surgery.
    O’Holleran performed the recommended surgery on
    June 5, 2009. Almost six months later, after the plaintiff
    completed another course of physical therapy, O’Hol-
    leran gave him a medical release to return to full work
    duties on November 18, 2009.
    Thereafter, the plaintiff took a new job with Charm
    Sciences, another Massachusetts manufacturer, for
    which he mixed commercial grade chemicals. While
    working at Charm Sciences on December 30, 2009, the
    plaintiff reinjured his left shoulder when lifting a forty
    pound box. As a result of this reinjury, the plaintiff
    experienced ‘‘difficulty reaching behind his shoulder as
    well as . . . overhead.’’ The following week, the plain-
    tiff was reexamined by O’Holleran, who gave him
    another cortisone injection, placed him on a light duty
    work restriction, and recommended that he undergo
    an additional six weeks of physical therapy. On March
    22, 2010, when the plaintiff was reexamined by O’Hol-
    leran after he had completed the recommended course
    of physical therapy, he reported that his shoulder had
    experienced ‘‘a dramatic improvement . . . .’’ Accord-
    ingly, the plaintiff requested that O’Holleran give him
    a release to return to full work duty and a clearance
    ‘‘to do some weight training and lifting.’’ O’Holleran
    gave the plaintiff a release to return to full work duty
    and instructed him to return ‘‘on an as-needed basis.’’
    On June 2, 2011, the plaintiff returned to O’Holleran,
    complaining of persistent pain in his left shoulder.
    O’Holleran gave the plaintiff another cortisone injection
    and instructed him to undergo additional physical ther-
    apy. These conservative treatments proved to be unsuc-
    cessful, however, and the plaintiff remained unable to
    return to work throughout July, 2011. Thereafter, the
    plaintiff underwent another MRI scan on August 31,
    2011. On September 15, 2011, when O’Holleran
    reviewed the new MRI scan with the plaintiff, he opined
    that, although the plaintiff had not suffered a new tear
    in his left shoulder, there was ‘‘a high degree of [inflam-
    mation] within the tissue inside the AC joint.’’ After
    discussing several treatment options with O’Holleran,
    the plaintiff elected to undergo a second surgery for
    shoulder arthroscopy, lysis of adhesions, and debride-
    ment,2 which O’Holleran performed on February 28,
    2012. Although the second surgery was performed with-
    out complication, the plaintiff remained unable to work
    for several months thereafter.
    In April, 2013, the plaintiff was employed by the
    defendant Edson Manufacturing,3 a Connecticut manu-
    facturer, as a mechanic and machine operator. As part
    of his duties, the plaintiff used a dolly4 to bring barrels
    of nails to the company’s rivet-making machines and
    to transport finished rivets to other locations in the
    factory after they were made. While working on April
    15, 2013, the plaintiff prepared to move a barrel of
    stainless steel nails weighing approximately 100
    pounds. To do so, he first positioned himself behind
    the dolly and barrel, then, with his right hand on the
    back of the dolly, reached out with his left arm and
    placed his left hand on the rim of the barrel. Then, with
    his left hand gripping the rim of the barrel, the plaintiff
    pulled the barrel of nails toward his chest until he felt
    a sudden ‘‘pop’’ in his left shoulder. The plaintiff did
    not inform anyone of his injury at the time he sustained
    it, nor did he request time off from work after he finished
    his shift that day. Rather, he continued to work for the
    defendant, without complaint, for the next eleven days,
    until he was laid off on April 26, 2013.
    Because the layoff was supposed to be temporary, the
    plaintiff intended to return to his job with the defendant
    when it was over. On May 20, 2013, the defendant noti-
    fied the plaintiff, by text message, that he could return
    to work. The plaintiff responded by text message that
    he would return to work the following Monday. The
    defendant’s offer later was retracted, however, due to
    an unexpected delay in receiving certain materials
    and supplies.
    Two days later, on May 22, 2013, thirty-seven days
    after the plaintiff suffered his workplace injury, he went
    to the emergency room of Lawrence General Hospital
    in Lawrence, Massachusetts, complaining of pain in his
    left shoulder. Thereafter, the plaintiff was referred back
    to O’Holleran, who examined him on May 24, 2013.
    During that examination, the plaintiff stated that he had
    been experiencing ‘‘significant worsening pain’’ in his
    left shoulder since the date of his injury, which had
    caused him to be unable to sleep or to perform overhead
    activities without pain. Accordingly, O’Holleran ordered
    another MRI scan of the plaintiff’s left shoulder and gave
    him documentation stating that he would be unable to
    return to work until he was reevaluated.
    On July 9, 2013, the plaintiff filed a form 30C notice
    of his workers’ compensation claim.5 On July 7, 2013,
    more than seventy days after the date of his workplace
    injury, the plaintiff informed the defendant, for the first
    time, that he had suffered a shoulder injury while work-
    ing on April 15, 2013. After receiving the plaintiff’s form
    30C, the defendant requested, pursuant to General Stat-
    utes § 31-294f (a),6 that an independent medical exami-
    nation of the plaintiff be conducted in order to assist
    it in determining whether to accept or contest the plain-
    tiff’s workers’ compensation claim.
    Prior to that examination, on June 8, 2013, the plain-
    tiff underwent another MRI scan at the request of O’Hol-
    leran. On August 8, 2013, the plaintiff met with
    O’Holleran to discuss his findings. After reviewing the
    MRI scan, O’Holleran opined that the plaintiff had not
    aggravated a previous injury to his left shoulder on
    April 15, 2013, but, instead, had sustained a new injury—
    an anterior glenoid fracture with a bony Bankart lesion7
    and a Hill-Sachs lesion.8 O’Holleran then noted, ‘‘I feel
    that his fracture fragment is in very good position and
    does not need surgery at this time. Given that his origi-
    nal injury was in April, I feel that [the] fragment has
    essentially healed. He still certainly has the labral tear
    and he certainly has pain. . . . I have recommended a
    course of physical therapy . . . . Regarding work, he
    will be cleared for light duty with no lifting greater
    than [ten] pounds.’’ On September 11, 2013, however,
    O’Holleran changed that work restriction by ordering
    that the plaintiff not return to work until he was reevalu-
    ated. He later reaffirmed that total work restriction on
    October 23, 2013.
    On September 25, 2013, the plaintiff was examined
    by Steven E. Selden, an orthopedic surgeon selected
    by the defendant as its independent medical examiner.
    During that examination, the plaintiff informed Selden
    that, on April 15, 2013, ‘‘he was moving a barrel [when
    he] felt a pop in his left shoulder . . . [but] he did not
    feel any actual pain.’’ After reviewing O’Holleran’s May
    24, 2013 notes and the June 8, 2013 MRI scan that
    O’Holleran had ordered, Selden noted that the plaintiff
    had sustained a prior shoulder injury in 2009, in connec-
    tion with which he had undergone a ‘‘posterior capsular
    shift and distal clavicle excision.’’ (Emphasis added.)
    Selden concurred with O’Holleran that the plaintiff was
    then suffering from a Hill-Sachs lesion and a bony Bank-
    art lesion in his left shoulder. He did not agree, however,
    that this injury had occurred on April 15, 2013. Rather,
    he opined that ‘‘[the plaintiff] may have sustained a
    strain of his left shoulder as a result of moving a barrel
    . . . but he has a significant preexisting condition to
    his left shoulder for which he had two surgical proce-
    dures. It would be very helpful to have Dr. O’Holleran’s
    notes regarding prior treatment for the left shoulder.
    Certainly, the [plaintiff’s] Bankart lesion and Hill-Sachs
    lesion clearly preexisted April of 2013 based on the
    history reviewed. A course of physical therapy at this
    time would be appropriate.’’ Selden further opined that
    the plaintiff was not totally disabled but, instead, was
    capable of light duty work ‘‘with avoidance of lifting
    more than [twenty-five] pounds and . . . overhead
    reaching and lifting.’’
    On December 23, 2013, O’Holleran reexamined the
    plaintiff a final time. During that examination, the plain-
    tiff maintained that he was still experiencing persistent
    pain in his left shoulder, and thus he requested that a
    third surgery be performed. In light of the plaintiff’s
    repeated history of cortisone injections, use of anti-
    inflammatories, and physical therapy, none of which
    had yet proved to be successful, O’Holleran recom-
    mended that a third surgery be performed on the plain-
    tiff’s left shoulder.
    Thereafter, the commissioner directed the plaintiff,
    pursuant to § 31-294f (a), to submit to another medical
    examination by an independent medical examiner of
    the commissioner’s own choosing, Dr. Peter R. Barnett.
    After performing that examination on April 14, 2014,
    Barnett noted: ‘‘Currently, the [plaintiff] feels that his
    left shoulder complaints have worsened. . . . The
    [plaintiff] . . . complains of numbness and tingling cir-
    cumferentially throughout the entire left upper extrem-
    ity, intermittently present both during the day and at
    night since the injury.’’ After reviewing the plaintiff’s
    medical records, Barnett opined: ‘‘It is my impression
    based on information currently available that [the plain-
    tiff’s] bony Bankart lesion and Hill-Sachs lesion [are]
    attributable to the alleged work-related incident . . .
    on April 15, 2013.’’ Barnett further opined that, although
    the plaintiff had not yet reached maximum medical
    improvement, he was capable of limited work duty with
    restrictions against lifting or reaching overhead, repeti-
    tive use of the left arm, and lifting more than fifteen
    pounds.
    On July 14, 2014, the commissioner held a formal
    hearing on the plaintiff’s claims (1) for total incapacity
    benefits from June 24 to August 8, 2013; (2) for tempo-
    rary partial benefits from August 9 to October 23, 2013;
    and (3) for total incapacity benefits from October 24,
    2013 to July 14, 2014. At that hearing, the plaintiff testi-
    fied and produced documentary evidence, including
    MRI scans, the medical records of O’Holleran, Selden
    and Barnett, and transcripts of O’Holleran’s and Sel-
    den’s depositions. In response, the defendant produced,
    inter alia, a July 14, 2014 addendum to Selden’s medical
    report, wherein Selden stated that, although he had
    reviewed additional medical records pertaining to the
    plaintiff, he still believed that the plaintiff’s April 15,
    2013 injury did not cause his glenoid fracture and
    lesions. The defendant also submitted copies of certain
    text messages between the plaintiff and his manager,
    several documents regarding the plaintiff’s two prior
    workers’ compensation claims for injuries to his left
    shoulder, and several statements from the plaintiff’s
    former coworkers describing past conversations with
    the plaintiff, in which he had told them that he routinely
    did pushups in the morning before going to work.
    On January 5, 2015, the commissioner issued a writ-
    ten decision, in which he found, inter alia, that (1) the
    plaintiff had not informed either his employer or his
    coworkers of his workplace injury, or reported that he
    had any difficulty performing his job duties after the
    injury; (2) there was ‘‘[c]onflicting testimony . . . as
    to the [plaintiff’s] weightlifting activities’’ around the
    date of his injury; (3) Selden disagreed with the mecha-
    nism of injury, opining that the April 15, 2013 incident
    had ‘‘caused nothing more than a temporary, self-lim-
    ited strain of [the plaintiff’s] left shoulder’’; and (4) as
    to the extent of the plaintiff’s disability caused by his
    April 15, 2013 injury and resulting need for further medi-
    cal treatment, Selden’s opinions were more persuasive
    than those of O’Holleran and Barnett. On the basis of
    those findings, the commissioner concluded that the
    plaintiff had sustained a left shoulder injury in the
    course of his employment, for which he was entitled
    to receive ‘‘temporary total benefits for the period of
    June 24, 2013 through August 8, 2013.’’ The commis-
    sioner disagreed, however, that the April 15, 2013 inci-
    dent had caused either the plaintiff’s anterior glenoid
    fracture or his accompanying lesions. Instead, the com-
    missioner adopted Selden’s opinion that on April 15,
    2013, the plaintiff had suffered a shoulder sprain, and
    thus that ‘‘any [current] restrictions or limitations on
    his ability to work were unrelated to the April 15, 2013
    injury.’’ On those grounds, the commissioner denied
    the plaintiff’s claims for temporary partial benefits for
    the period from August 9 to October 23, 2013, and for
    temporary total benefits for the period from October
    24, 2013 to July 14, 2014.
    On February 18, 2015, the plaintiff appealed from the
    commissioner’s decision to the board, claiming that the
    commissioner had ‘‘erred in finding . . . Selden to be
    more persuasive than . . . O’Holleran and Barnett on
    the issues of extent of disability and medical treatment.’’
    In his accompanying brief, the plaintiff argued that Sel-
    den had formed his opinion as to causation and extent of
    disability without first reviewing the plaintiff’s medical
    records concerning the treatment of his prior shoulder
    injury from 2009 through 2012. As a result, he argued,
    Selden was unaware that the plaintiff’s prior injury was
    to the posterior labrum, whereas the April 15, 2013
    injury here at issue was to his anterior labrum. The
    plaintiff thus argued that ‘‘[b]ecause . . . Selden did
    not have sufficient subordinate facts to render an opin-
    ion [to a reasonable degree of medical probability], the
    commissioner erred in relying on his testimony.’’ Last,
    the plaintiff claimed that the commissioner did not ade-
    quately articulate why he had disregarded the opinion
    of Barnett, his own medical examiner, in making his
    findings and issuing his award in this case. On those
    grounds, the plaintiff requested that the board reverse
    the commissioner’s decision and find that the plaintiff
    was entitled to benefits ‘‘from August 8, 2013, to the
    present and continuing until a form 36 is approved.’’
    On June 26, 2015, the board held a hearing on the
    plaintiff’s claims. On October 6, 2015, it issued a written
    decision affirming the commissioner’s decision. In so
    doing, the board found, inter alia, that (1) Selden had
    offered a reasonable basis for his medical opinions as
    to causation; (2) the commissioner’s findings were sup-
    ported by adequate subordinate facts; (3) the commis-
    sioner correctly applied the law to the facts found; and
    (4) the commissioner’s written decision ‘‘complie[d]
    with the standard we have delineated for a decision
    which does not rely on the opinion of the commission-
    er’s examiner.’’ Thereafter, the plaintiff filed the present
    appeal. Additional facts will be set forth as necessary.
    I
    On appeal, the plaintiff first claims that the board
    erred in affirming the commissioner’s decision because
    the commissioner’s findings regarding the cause and
    extent of the plaintiff’s disability were not supported
    by sufficient subordinate facts. In support of his argu-
    ment, the plaintiff asserts that Selden had formed his
    opinion as to the cause and extent of the plaintiff’s
    disability before he had reviewed the plaintiff’s medical
    records regarding the prior injuries to and correspond-
    ing treatments for his left shoulder. The plaintiff argues
    that, without first acquainting himself with the plain-
    tiff’s entire medical history, Selden’s opinion that the
    plaintiff’s fracture and lesions preexisted the April 15,
    2013 injury was the product of speculation and conjec-
    ture, and thus his opinion could not be stated to a
    reasonable degree of medical probability. Therefore,
    the plaintiff argues, the commissioner’s decision, which
    relied heavily on Selden’s opinion, was based on specu-
    lation and conjecture. In the alternative, the plaintiff
    argues that because none of the medical examiners in
    this case testified before the commissioner at the July
    14, 2014 formal hearing, this court is not obligated to
    defer to the commissioner’s credibility determinations
    and, instead, should conclude that the commissioner
    erred by not adopting the more persuasive opinions of
    O’Holleran and Barnett. See Bode v. Connecticut Mason
    Contractors, The Learning Corridor, 
    130 Conn. App. 672
    , 
    25 A.3d 687
    , cert. denied, 
    302 Conn. 942
    , 
    29 A.3d 467
     (2011).
    The defendant disagrees, asserting that the board
    deferred appropriately to the commissioner’s factual
    findings and credibility determinations. In support of
    its argument, the defendant argues that causation is a
    question of fact and, if presented with conflicting medi-
    cal testimony, the commissioner has the sole discretion
    to determine whose opinions to credit and what weight
    to give to such opinions. Therefore, the defendant
    argues, the board correctly held that it could not reject
    the commissioner’s finding that Selden’s opinion was
    more persuasive than those of O’Holleran and Barnett.
    The defendant further argues that the board correctly
    held that Selden offered a reasonable basis for his opin-
    ions on causation and that, unlike the medical expert
    in DiNuzzo v. Dan Perkins Chevrolet Geo, Inc., 
    294 Conn. 132
    , 
    982 A.2d 157
     (2009)—a case upon which the
    plaintiff relies for his argument that Selden’s opinion
    was the product of speculation and conjecture—Selden
    physically examined the plaintiff and, on two separate
    occasions, reviewed additional medical information
    prior to submitting the July 14, 2014 addendum to his
    report, wherein he affirmed his original opinion that
    the plaintiff suffered a shoulder sprain on April 15, 2013.
    The defendant thus argues that the board did not abuse
    its discretion in affirming the commissioner’s decision.
    We agree with the defendant.
    The following additional facts, as presented to the
    commissioner, are relevant to this claim. As discussed
    in the preceding paragraphs, the commissioner was pre-
    sented with the plaintiff’s live testimony and documen-
    tary evidence of the plaintiff’s medical history and
    examinations. In his testimony, the plaintiff was asked,
    and he answered, several questions as to whether he
    exercised or lifted weights around the date of his injury.
    The plaintiff denied that he had ever engaged in weigh-
    tlifting, exercising at a gym, or even exercising at home.
    Moreover, the plaintiff denied that he had ever asked
    O’Holleran to provide him with a medical release so
    that he could resume weightlifting. The defendant chal-
    lenged this testimony by submitting statements from
    three of the plaintiff’s former coworkers, describing
    separate conversations with the plaintiff, in which he
    had told them that he did pushups and sit-ups every
    day before going to work. In one such conversation, a
    coworker recalled that the plaintiff had bragged about
    ‘‘how easy [his job] was because ‘he was used to doing
    200 pushups and 200-300 sit-ups among other exercises
    every morning before work’ . . . .’’
    The documentary evidence presented at the formal
    hearing included, inter alia, O’Holleran’s February 27,
    2014 deposition. At the deposition, O’Holleran testified
    that he had reviewed his notes from the years 2009 to
    2013, as well as MRI scans and X-rays he had ordered
    of the plaintiff’s shoulder. On the basis of those records,
    O’Holleran opined, inter alia, that the incident on April
    15, 2013, had caused the glenoid fracture, the bony
    Bankart lesion and the Hill-Sachs lesion in the plaintiff’s
    left shoulder; this injury was unrelated to the plaintiff’s
    prior shoulder surgeries in 2009 and 2012; the plaintiff
    had not yet reached maximum medical improvement
    following his April 15, 2013 injury; and, in light of the
    fact that the plaintiff had exhausted all conservative
    treatment options for his shoulder, surgery would be
    the next logical step, after which the plaintiff would
    need approximately nine months to fully recover.
    In explaining the basis for his opinions, O’Holleran
    stated that the plaintiff’s present fracture and lesions
    were in the anterior portion of the labrum, and thus
    could not have been an aggravation of the plaintiff’s
    prior injury, which was to his posterior labrum; the
    plaintiff’s report of feeling a ‘‘pop’’ at the time he was
    injured was consistent with experiencing a glenoid frac-
    ture and a labral tear; and, although a recent MRI scan
    showed that the fracture had healed, it was likely that
    the plaintiff’s labrum was still torn, and that the tear
    was causing the plaintiff’s pain. Last, O’Holleran noted
    the presence of bone marrow edema9 in the plaintiff’s
    shoulder, which was consistent with a recent injury to
    his shoulder joint.
    O’Holleran’s testimony, however, was not unquali-
    fied. Thus, as to the mechanism of the plaintiff’s injury,
    O’Holleran conceded: ‘‘I have zero opinion as to
    whether or not he truly injured his shoulder as he said
    he did at work. . . . I wasn’t there . . . . I can only
    go by what the patient tells me in the office.’’ Moreover,
    after he was asked to assume that the plaintiff had
    operated the dolly in a conventional manner, O’Holleran
    conceded that it would have been uncommon for such
    activity to cause this type of injury. O’Holleran further
    conceded that a glenoid fracture that causes a bony
    Bankart lesion and Hill-Sachs lesion is a painful injury,
    and that it was ‘‘unusual’’ for the plaintiff to have waited
    five weeks before seeking medical treatment. Regarding
    the current status of the plaintiff’s injury, O’Holleran
    agreed that the recent scans showed that the fracture
    had healed, but stated both that he would be unable to
    determine the extent of the injury until he performed
    an incision on the shoulder joint, and that he lacked
    objective evidence to explain the plaintiff’s current neu-
    rological complaints. As to the benefits of undergoing
    a third surgery, O’Holleran stated: ‘‘I think, given [that]
    he has not improved in [ten] months, and . . . assum-
    ing that his condition hasn’t changed, I think [that] it’s
    unlikely he’s going to get much better.’’ Last, when
    asked about the March 22, 2010 note regarding the plain-
    tiff’s desire to return to weightlifting and exercising,
    O’Holleran stated that, although he had no independent
    recollection of the plaintiff’s exercise habits, he did not
    believe that the note was a mistake.
    Selden’s deposition occurred on December 2, 2013.
    At his deposition, Selden testified that, prior to forming
    his opinions, he had physically examined the plaintiff,
    performed a neurological assessment of him, and
    reviewed O’Holleran’s May 24, 2013 notes as well as
    the June 8, 2013 MRI scan that O’Holleran had ordered.
    Selden further testified that, after his September 25,
    2013 examination of the plaintiff but before he gave his
    deposition, he had received and reviewed additional
    medical records for the plaintiff.10 When questioned as
    to the results of the June 8, 2013 MRI scan, Selden
    acknowledged that it showed a glenoid fracture as well
    as a bony Bankart lesion and a Hill-Sachs lesion. He
    maintained, however, that this injury had not occurred
    on April 15, 2013. Selden explained that his opinion was
    based on two factors: (1) the mechanism of injury, as
    described by the plaintiff, was inconsistent with causing
    a glenoid fracture; and (2) the plaintiff’s claim that he
    did not feel any pain when he sustained the injury was
    inconsistent with sustaining a glenoid fracture. As to
    the mechanism of injury, Selden testified that ‘‘lifting
    a barrel, whether it’s manually . . . or using . . .
    some type of dolly, is inconsistent with fracturing your
    glenoid. . . . It’s the wrong mechanism to cause a frac-
    ture.’’ As to the amount of pain the plaintiff reportedly
    felt at the time of his injury, moreover, Selden testified,
    ‘‘I have not seen anybody with a glenoid fracture that
    didn’t have significant pain in their shoulder, as with
    any fracture around the shoulder. That’s a painful injury.
    I’ve personally not [seen] any patients with fractures
    such as that, and I’ve seen lots over the years, who
    have not had significant pain.’’
    On those grounds, Selden opined, inter alia, that the
    plaintiff likely suffered a shoulder strain on April 15,
    2013; given the plaintiff’s history of shoulder injuries,
    a sprain of this nature would have healed within approx-
    imately six to eight weeks; notwithstanding such a
    shoulder sprain, the plaintiff would have retained a light
    duty work capacity, and should have reached maximum
    medical improvement within six months of the date of
    the injury; there was no discernible reason for addi-
    tional surgery on the shoulder; and he did not believe
    that the plaintiff’s current complaints of persistent pain
    and numbness were connected to the April 15, 2013
    work injury because the plaintiff did not complain of,
    nor did Selden observe any evidence that he was experi-
    encing, any numbness or nerve damage when he per-
    formed his neurological examination of the plaintiff.
    Selden’s testimony, like O’Holleran’s, was not unqual-
    ified. When asked his opinion as to what had occurred
    when the plaintiff felt the ‘‘pop’’ in his shoulder, Selden
    opined that the plaintiff had either subluxed11 his shoul-
    der or felt the breaking of adhesions or residual scar
    tissue from his prior surgery. Thereafter, Selden agreed
    that the subluxation of the shoulder joint can cause a
    glenoid fracture resulting in Bankart lesions or Hill-
    Sachs lesions. He maintained, however, that the mecha-
    nism of injury and the amount of pain experienced
    on April 15, 2013, were inconsistent with sustaining a
    glenoid fracture.
    In addition to these deposition transcripts, the plain-
    tiff submitted the April 14, 2014 written report of Bar-
    nett, the commissioner’s medical examiner. In that
    report, Barnett noted that he had reviewed O’Holleran’s
    notes for the period from 2009 to 2013, as well as several
    X-rays and MRI scans performed between 2011 and
    2013. He then noted that the plaintiff had stated that ‘‘he
    was pushing with his left arm when he felt a popping
    sensation and mild pain.’’ (Emphasis added.) Barnett
    subsequently diagnosed the plaintiff as suffering from
    an anterior-inferior bony Bankart lesion and a poste-
    rior-superior bony Hill-Sachs lesion, further noting the
    presence of bone marrow edema in the plaintiff’s shoul-
    der. On the basis of those findings, Barnett opined:
    ‘‘It is my impression based on information currently
    available that [the plaintiff’s] bony Bankart lesion and
    Hill-Sachs lesion is attributable to the alleged work-
    related incident . . . on April 15, 2013. There is no
    indication that either of these problems was present at
    the time of his prior surgical procedures or prior care for
    the shoulder.’’ He further noted that, ‘‘[a]t this juncture
    surgical intervention on the left shoulder would not be
    recommended. . . . [I]t is recommended that the
    [plaintiff] undergo a neurologic assessment . . . to
    determine the cause and origin of the [plaintiff’s] non-
    specific neurologic complaints . . . .’’
    Last, on the day of the formal hearing, the defendant
    submitted an addendum to Selden’s report, dated July
    14, 2014, wherein Selden stated, ‘‘I have reviewed addi-
    tional medical records provided regarding [the plain-
    tiff].12 It remains my opinion that [the plaintiff] sustained
    a strain of his left shoulder as a result of moving a
    barrel on [April 15, 2013]. . . . It is my opinion that
    the incident of [April 15, 2013] caused nothing more
    than a temporary, self-limited strain of his left shoulder
    . . . [and] that any limitations on his ability to work at
    this time are unrelated to the incident of [April 15, 2013].
    (Footnote added.)
    In summarizing the commissioner’s findings, the
    board recalled that the commissioner had ‘‘noted that
    the medical evidence in this claim was disputed, and
    there was inconsistency between the [plaintiff’s] narra-
    tive as to his exercise regimen and the reports of his
    treating physician.’’ Thereafter, the board held that, in
    light of Selden’s examination and conclusions, as con-
    firmed by his July 14, 2014 addendum, ‘‘the opinions
    that [Selden] provided in this case were . . . compe-
    tent evidence that the trial commissioner could reason-
    ably rely upon. To the extent the initial opinions
    rendered by [Selden] had deficiencies, we believe that
    they were sufficiently clarified by the addendum sub-
    mitted . . . to constitute a reliable expert opinion.’’
    Thus, the board held that the commissioner’s conclu-
    sion ‘‘[was] consistent with a medical opinion he found
    persuasive and reliable.’’ With these additional facts in
    mind, we turn to the merits of the plaintiff’s claims.
    A
    We first address the plaintiff’s argument that Selden’s
    opinion was not competent medical evidence supported
    by sufficient subordinate facts, and thus that the com-
    missioner’s decision, which relied heavily on that opin-
    ion, was based on speculation and conjecture. The
    gravamen of the plaintiff’s argument is that Selden was
    unaware, when formulating his opinions, that the plain-
    tiff’s prior injuries were to the posterior labrum—
    whereas his current injury was to the anterior labrum—
    and that his written opinion was directly contradicted
    by his subsequent deposition testimony. We are unper-
    suaded.
    ‘‘[W]e first set forth our standard of review for work-
    ers’ compensation appeals. The commissioner is the
    sole trier of fact and [t]he conclusions drawn by [the
    commissioner] from the facts found must stand unless
    they result from an incorrect application of the law to
    the subordinate facts or from an inference illegally or
    unreasonably drawn from them. . . . The review
    [board’s] hearing of an appeal from the commissioner
    is not a de novo hearing of the facts. . . . [I]t is [obli-
    gated] to hear the appeal on the record and not retry
    the facts. . . . On appeal, the board must determine
    whether there is any evidence13 in the record to support
    the commissioner’s findings and award. . . . Our
    scope of review of [the] actions of the [board] is [simi-
    larly] . . . limited. . . . [However] [t]he decision of
    the [board] must be correct in law, and it must not
    include facts found without evidence or fail to include
    material facts which are admitted or undisputed.’’

    (2001). Moreover, ‘‘[i]t matters not that the basic facts
    from which the [commissioner] draws this inference
    are . . . controverted. . . . It is likewise immaterial
    that the facts permit the drawing of diverse inferences.
    The [commissioner] alone is charged with the duty of
    initially selecting the inference which seems most rea-
    sonable and [the commissioner’s] choice, if otherwise
    sustainable, may not be disturbed by a reviewing court.’’

    ‘‘[T]here must [however] be subordinate facts from
    which the conclusion that there is a causal connection
    between the employment and the injury can be drawn.
    . . . [Thus, the] right of a claimant to compensation
    must be based [on] more than speculation and conjec-
    ture.’’ (Internal quotation marks omitted.) DiNuzzo v.

    Accordingly, ‘‘[a]lthough . . . the board is prohibited
    from retrying the case or substituting its inferences for
    those drawn by the commissioner, the board certainly
    [is] free to examine the record to determine whether
    competent evidence supported the commissioner’s
    findings, inferences drawn from such findings and con-
    clusions.’’ Dengler v. Special Attention Health Services,
    Inc., 
    supra, 450
    .
    In the present case, the plaintiff argues that the com-
    missioner’s findings were not supported by competent
    medical evidence because, at the time he formed his
    opinions, Selden was unaware that the plaintiff’s prior
    injuries involved the plaintiff’s anterior labrum, not the
    posterior labrum. The plaintiff thus argues, citing
    DiNuzzo v. Dan Perkins Chevrolet Geo, Inc., 
    supra,
     
    294 Conn. 132
    , that, without knowing the entirety of the
    plaintiff’s prior medical history, Selden’s opinion on
    causation and extent of disability amounted to mere
    speculation and conjecture, and thus ‘‘there were insuf-
    ficient subordinate facts in the record to support the
    commissioner’s finding’’; 
    id., 143
    ; which was predicated
    on Selden’s expert testimony.
    After carefully reviewing the record in this case, we
    conclude that the board did not err in determining that
    Selden offered a reasonable basis for his opinion, and
    thus that the commissioner’s decision, which relied
    upon that opinion, was supported by sufficient subordi-
    nate facts to require that it be affirmed. First, in his
    September 25, 2013 report, Selden specifically noted
    that he had reviewed the plaintiff’s past medical history,
    which revealed that, in 2009, the plaintiff had injured
    his shoulder and ‘‘underwent a posterior capsular shift
    and distal clavicle excision. He did not do well and had
    a second surgery in June of 2012. He underwent lysis
    of adhesions.’’ (Emphasis added.) Thereafter, during
    his December 2, 2013 deposition, Selden agreed with
    the statement by the defendant’s counsel that he
    reviewed ‘‘a couple of additional medical records from
    the past which [he] did not have’’ at the time of his
    examination. Last, in his July 14, 2014 addendum, Sel-
    den again reported that he had reviewed additional
    medical records, but that his opinion remained
    unchanged: the April 15, 2013 incident had caused noth-
    ing more than a shoulder strain, and any current limita-
    tions on the plaintiff’s ability to work were unrelated
    to that incident. Looking at ‘‘the entire substance of
    the expert’s testimony’’; O’Reilly v. General Dynamics
    Corp., 
    52 Conn. App. 813
    , 817, 
    728 A.2d 527
     (1999); it
    is apparent that Selden was aware that the plaintiff’s
    2009 injury was to the posterior labrum and that, after
    personally examining the plaintiff, reviewing his past
    medical history, and twice reviewing additional medical
    reports, his opinion remained constant.
    For that reason, we conclude that the board correctly
    determined that Selden’s opinions were unlike those of
    the claimant’s medical examiner in DiNuzzo v. Dan
    Perkins Chevrolet Geo, Inc., 
    supra,
     
    294 Conn. 132
    . In
    DiNuzzo, the decedent’s spouse ‘‘submitted a claim for
    dependent widow’s benefits pursuant to . . . [General
    Statutes] § 31-306.’’ (Internal quotation marks omitted.)
    Id., 134. In support of her claim, the claimant submitted
    a medical report prepared by the decedent’s physician,
    in which the doctor ‘‘stated that the cause of [the dece-
    dent’s] death was heart disease, secondary to athero-
    sclerotic heart disease . . . brought about by the
    curtailment of his physical activities . . . [and that the
    decedent’s prior] compensable injury and its treatment
    substantially contributed to his death . . . because
    they severely limited his ability to maintain his physical
    fitness and aerobic conditioning.’’ (Internal quotation
    marks omitted.) Id., 135. Thereafter, the commissioner
    in DiNuzzo found ‘‘that there was a relationship
    between the compensable injury and the decedent’s
    death . . . [and, on that basis,] concluded that the
    plaintiff was entitled to benefits pursuant to § 31-306.’’
    (Internal quotation marks omitted.) Id., 136.
    On appeal in DiNuzzo, our Supreme Court affirmed
    the judgment of this court, which reversed the board’s
    affirmance of the commissioner’s decision. In so doing,
    the DiNuzzo court noted that the medical examiner,
    upon whose opinion the commissioner had relied, had
    made the following concessions of fact which under-
    mined his opinion: (1) the decedent had not been diag-
    nosed with atherosclerotic heart disease; (2) the
    medical examiner was unaware that ‘‘the decedent had
    been hospitalized approximately one month before his
    death for certain side effects of Interferon’’; id., 145;
    (3) the symptoms exhibited by the decedent shortly
    before his death ‘‘could have been the result of his use
    of Interferon’’; id.; and (4) because he did examine the
    decedent’s body postmortem, ‘‘it would be impossible
    to know whether the heart attack could have been pre-
    vented if the decedent had been able to exercise more
    because some heart attacks are caused by congenital
    heart defects that are not amenable to improvement
    through exercise.’’ Id., 146. The court then noted that,
    aside from this unsupported medical opinion, ‘‘the
    plaintiff produced no evidence linking the decedent’s
    death to a heart attack.’’ Id., 144. Accordingly, the court
    held that that medical opinion amounted to no more
    than speculation and conjecture, and thus ‘‘the causal
    link between his compensable injury and his alleged
    manner of death simply [became] too attenuated to
    support a reasonable inference that the two events were
    connected.’’ Id., 148.
    Here, unlike the medical examiner in DiNuzzo, Sel-
    den physically examined and performed a neurological
    assessment of the plaintiff, reviewed O’Holleran’s May,
    2013 medical notes, the June 8, 2013 MRI scan, which
    O’Holleran had ordered, and twice reviewed additional
    medical records concerning the plaintiff’s prior shoul-
    der injuries. In light of these facts, the commissioner
    in this case had far more evidence on the record before
    him to substantiate Selden’s opinion as to the nature
    and extent of the plaintiff’s injury than the medical
    examiner whose opinion was rejected as speculative
    and conjectural in DiNuzzo. See id., 145–48. Because
    Selden provided a reasonable basis for his opinion, that
    opinion was competent medical evidence supported by
    sufficient underlying facts to justify the commissioner’s
    reliance upon it in reaching his decision in this case.
    Last, we are not persuaded by the plaintiff’s argument
    that Selden’s written report was so contradicted by
    his deposition testimony, or that any inconsistencies
    between the report and the deposition were so substan-
    tial, as to make it inappropriate for the commissioner
    to rely on the report in making his findings in this
    case. Although the plaintiff correctly notes that Selden
    testified that he believed that the plaintiff may have
    subluxed his shoulder on April 15, 2013, and that a
    shoulder subluxation can result in a glenoid fracture,
    there are two fundamental flaws in the plaintiff’s argu-
    ment. First, Selden testified that the ‘‘pop’’ in the plain-
    tiff’s shoulder could have been either a subluxation or
    a tearing of preexisting adhesions and scar tissue, either
    of which could have caused the plaintiff’s shoulder
    strain without causing the glenoid fracture. Second, the
    plaintiff fails to acknowledge that, even if he did sublux
    his shoulder on April 15, 2013, and a subluxation can
    cause a glenoid fracture, those possibilities do not com-
    pel a finding that the particular subluxation, if any, that
    occurred on April 15, 2013, is what caused the glenoid
    fracture. Instead, both Selden and the commissioner
    reasonably could have concluded that the plaintiff, who
    claimed to have routinely done 200 pushups per day,
    sustained a second subluxation that caused the glenoid
    fracture after the date of his workplace injury on April
    15, 2013, but before he went to the hospital on May 22,
    2013. We thus cannot find that Selden’s written opinion
    was so squarely contradicted by his deposition testi-
    mony as to render his opinion speculative or con-
    jectural.
    ‘‘Once the commissioner makes a factual finding, [we
    are] bound by that finding if there is evidence in the
    record to support it. . . . Similarly, the conclusions
    drawn by the commissioner from the facts found must
    stand unless they result from an incorrect application
    of the law to the subordinate facts or from an inference
    illegally or unreasonably drawn from them. . . . It [is]
    within the commissioner’s discretion to credit all, part
    or none of the . . . [expert] testimony. That determina-
    tion cannot be overruled by the board unless it could not
    find any evidence to support the conclusion.’’ (Citations
    omitted; emphasis added; internal quotation marks
    omitted.) O’Reilly v. General Dynamics Corp., supra,
    
    52 Conn. App. 818
    –19. In light of the foregoing analysis,
    we agree with the board that Selden’s opinion was sup-
    ported by sufficient subordinate facts to constitute com-
    petent medical evidence upon which the commissioner
    properly could rely in making his findings in this case.
    We thus conclude that the board correctly determined
    that the commissioner’s findings were supported by
    sufficient underlying facts to uphold them, and that any
    inferences drawn from such facts were reasonable and
    legally permissible. See, e.g., Blakeslee v. Platt Bros. &
    Co., 
    279 Conn. 239
    , 243, 
    902 A.2d 620
     (2006).
    B
    Notwithstanding our conclusion that the commis-
    sioner’s findings were supported by sufficient underly-
    ing facts, the plaintiff argues, in the alternative, under
    Bode v. Connecticut Mason Contractors, The Learning
    Corridor, supra, 
    130 Conn. App. 672
    , that this court
    should depart from the degree of deference usually
    afforded to the commissioner’s credibility determina-
    tions and conclude that the commissioner erred in not
    adopting the opinions of O’Holleran and Barnett. This
    is so, the plaintiff argues, because none of the medical
    examiners gave live testimony before the commissioner
    at the July, 2014 formal hearing; rather, each examiner
    submitted a written report concerning his own medical
    evaluation of the plaintiff. The plaintiff argues that,
    under these circumstances, the commissioner’s credi-
    bility determinations were not influenced by the live
    testimony of those witnesses, and thus this court is
    equally capable of determining the appropriate weight
    to afford the opinions of Selden, O’Holleran and Barnett.
    We disagree and conclude that the defendant’s reliance
    on Bode is misplaced.
    In Bode, the claimant sought temporary total disabil-
    ity benefits for fractures to his spine and shoulder that
    he sustained in 2002, after falling thirty feet from scaf-
    folding. 
    Id., 674
    . Although the claimant submitted a
    number of medical records in support of his claim,
    ‘‘[n]one of the physicians opined that the [claimant]
    was totally disabled or unable to work on or after April
    26, 2005.’’ 
    Id., 676
    . In addition to these reports, the
    claimant submitted four vocational evaluations.
    Although the first two evaluations, performed in Octo-
    ber, 2003, and January, 2004, had concluded that the
    claimant was ‘‘ ‘presently employable,’ ’’ the last two
    evaluations, which were performed in August, 2004, and
    July, 2008, had concluded that ‘‘due to his worsening
    condition the [claimant] was completely unemploy-
    able.’’ 
    Id., 677
    . In January, 2009, the commissioner dis-
    missed the claimant’s request for disability benefits. 
    Id., 678
    . Thereafter, the board affirmed the commissioner’s
    finding, concluding, inter alia, that ‘‘the [claimant] failed
    to meet his burden of proving eligibility for temporary
    total disability benefits because . . . he did not intro-
    duce one medical report in which a physician opined
    that [he] was totally disabled . . . . [Thus] because
    this board is not empowered to overturn a trier’s eviden-
    tiary determinations unless they lack foundation in the
    record . . . the trial commissioner’s decision . . .
    must stand.’’ (Internal quotation marks omitted.) 
    Id.
    On appeal in Bode, the claimant argued that the board
    had improperly affirmed the commissioner’s decision
    because, inter alia, the commissioner ‘‘arbitrarily disre-
    garded . . . the uncontroverted vocational expert
    opinions . . . .’’ 
    Id., 679
    . This court agreed and
    reversed the decision of the board. 
    Id.
     In so doing, the
    court in Bode acknowledged that the claimant had not
    introduced a single medical report establishing his total
    disability. It held, however, that ‘‘[t]he commissioner’s
    inquiry . . . as to whether the plaintiff was realistically
    employable should not have ended with his review . . .
    of the plaintiff’s physical capabilities. Under the facts
    of this case, the commissioner’s decision necessarily
    involved his consideration of the . . . four vocational
    reports’’ as part of his decision as to whether the claim-
    ant proved his entitlement to temporary total disability
    benefits. 
    Id.,
     681–82.
    After reviewing the evidence presented to the com-
    missioner, the court in Bode noted that none of the
    vocational experts had testified before the commis-
    sioner and that, of the four vocational reports, only
    the February, 2004 report unequivocally stated that the
    plaintiff presently was employable. 
    Id., 682
    . Further,
    the court in Bode noted that the November, 2003 and
    the July, 2008 vocational reports had been authored by
    the same evaluator, who had changed his opinion in
    his 2008 report by finding that the claimant, at that time,
    was ‘‘ ‘totally unemployable.’ ’’ 
    Id., 684
    . Last, the court
    noted that the commissioner’s decision discussed only
    the vocational reports suggesting that the plaintiff was
    employable, but made no finding as to the reliability of
    the August, 2004 or July, 2008 reports that had stated
    that the plaintiff was unemployable. 
    Id., 684
    .
    In reversing the decision of the board, the court in
    Bode ‘‘declined to afford deference to the commission-
    er’s credibility determinations when such determina-
    tions were based solely on documentary evidence,
    noting that ‘no testimony regarding any of the underly-
    ing assertions was taken. All of the facts . . . were
    reflected in the medical reports from the physicians
    . . . . Thus, the deference [that] we normally would
    give to the commissioner on issues of credibility is not
    warranted in the present case, because we are as able
    as he was to gauge the reliability of those documents.’ ’’
    
    Id., 685
    , quoting Pietraroia v. Northeast Utilities, 
    254 Conn. 60
    , 75, 
    756 A.2d 845
     (2000).
    In the present case, the plaintiff argues, pursuant to
    Bode, that this court should decline to give deference to
    the commissioner’s credibility determinations because
    here, as in Bode, none of the medical examiners testified
    before the commissioner, and thus this court is assert-
    edly no less capable than the commissioner of deciding
    what weight to give to those reports. We disagree. Our
    conclusion rests on the fact that the commissioner’s
    credibility determinations and findings in the present
    case were clearly influenced by the plaintiff’s live testi-
    mony that he never engaged in weightlifting or other
    forms of physical exercise. As discussed in the preced-
    ing paragraphs, the plaintiff was questioned as to
    whether he had ever lifted weights, requested a medical
    release from O’Holleran to resume weightlifting, or had
    conversations at work about doing pushups and sit-
    ups every day before going to work. The plaintiff flatly
    denied these allegations. His testimony was directly
    contradicted, however, both by O’Holleran’s medical
    notes and by the statements of his former coworkers.
    In his decision, the commissioner expressly found that
    there was ‘‘[c]onflicting testimony . . . between the
    [plaintiff] and [O’Holleran] as to the [plaintiff’s] weigh-
    tlifting activities and performing pushups’’; that Selden
    ‘‘disagreed with the [plaintiff’s] mechanism of the
    injury’’; and that ‘‘the opinions and conclusions of [Sel-
    den are] more persuasive in part than those of . . .
    O’Holleran and Barnett on the issues of extent of disabil-
    ity and need for further medical treatment.’’
    Against this background, we conclude that here,
    unlike in Bode, the commissioner was presented with
    ‘‘ ‘[live] testimony regarding . . . the [claimant’s]
    underlying assertions’ ’’; Bode v. Connecticut Mason
    Contractors, The Learning Corridor, supra, 
    130 Conn. App. 685
    ; not just written reports from nontestifying
    experts, upon which to make his findings and conclu-
    sions. It is well settled that ‘‘[the] authority to find the
    facts entitles the commissioner to determine the weight
    of the evidence presented and the credibility of the
    testimony offered by lay and expert witnesses.’’ (Inter-
    nal quotation marks omitted.) Ryker v. Bethany, 
    97 Conn. App. 304
    , 314,

    , cert. denied, 
    280 Conn. 932
    , 
    909 A.2d 958
     (2006). Moreover, ‘‘[e]ven if
    the medical evidence . . . is not refuted, the [commis-
    sioner] can still dismiss the claim if [he] does not find
    the injured worker to be credible.’’ 3 A. Sevarino, Con-
    necticut Workers’ Compensation After Reforms (J. Pas-
    saretti, Jr., ed., 6th Ed. 2014) § 6.02.3, p. 760. Under the
    circumstances of this case, we see no compelling reason
    to give less deference to the commissioner’s findings
    than we usually give to such findings in similar cases.14
    II
    The plaintiff’s final claim is that the board erred in
    not remanding the case to the commissioner with
    instructions that the commissioner articulate why he
    disregarded the opinion of Barnett, the medical exam-
    iner he chose to examine the plaintiff. In support of this
    claim, the plaintiff argues that, although a commissioner
    may ‘‘[choose] not to adopt the diagnosis of the physi-
    cian performing [the commissioner’s] examination,’’ the
    commissioner ‘‘should articulate the reasons behind
    his or her decision to disregard the examiner’s report’’
    because it ‘‘has long been the expectation within work-
    ers’ compensation law . . . that the [commissioner’s]
    examiner’s opinion will provide strong guidance to the
    commissioner’s ultimate decision.’’ (Internal quotation
    marks omitted.) The plaintiff asserts that the commis-
    sioner’s decision in this case ‘‘summarily states the opin-
    ions and conclusions of [Selden]’’ without including
    ‘‘any explanation whatsoever for this departure,’’ and
    thus the board erred in not remanding this case to the
    commissioner for further articulation. We disagree.
    The following facts are pertinent to this claim. In his
    decision, the commissioner found, inter alia, that (1)
    Selden ‘‘opined in pertinent part that the [plaintiff] may
    have sustained a strain to his left shoulder’’; (2) ‘‘Dr.
    Barnett opined, in relevant part, causally relating the
    present injury to the April 15, 2013 work-related inci-
    dent, did not recommend surgical intervention . . .
    and recommended the [plaintiff] undergo a neurologic
    assessment’’; and that (3) ‘‘the opinions and conclusions
    of [Selden are] more persuasive in part than those of
    . . . O’Holleran and Barnett on the issues of extent of
    disability and need for further medical treatment.’’ On
    those grounds, the commissioner agreed with Selden
    that the plaintiff’s April 15, 2013 injury ‘‘was self-limiting
    in nature . . . any restrictions or limitations on his
    ability to work were unrelated to the April 15, 2013
    injury . . . [and that] no further medical treatment is
    required as it relates to the April 15, 2013 injury.’’
    In affirming that decision, the board held, in part,
    that it ‘‘reviewed the finding [and] award and [identified]
    no legal error.’’ The board further held that ‘‘the text
    of the finding [and] award complies with the standard
    we have delineated for a decision which does not rely
    on the opinion of the commissioner’s examiner.’’ After
    reviewing the contents of the commissioner’s decision,
    the board concluded that the reasoning for the commis-
    sioner’s departure from Barnett’s medical opinion ‘‘is
    clearly ascertainable in this opinion.’’
    When reviewing the decision of the board, ‘‘[t]he role
    of this court is to determine whether the . . . [board’s]
    decision results from an incorrect application of the law
    to the subordinate facts or from an inference illegally or
    unreasonably drawn from them.’’ (Internal quotation
    marks omitted.) Tartaglino v. Dept. of Correction, 
    55 Conn. App. 190
    , 193, 
    737 A.2d 993
    , cert. denied, 
    251 Conn. 929
    , 
    742 A.2d 364
     (1999). ‘‘[T]he discretion [to
    remand the case] is a legal discretion vested in the
    [board],’’ and thus we review that decision to determine
    ‘‘whether the [board’s] failure to remand the case to
    the commissioner constituted an abuse of its discretion
    . . . .’’ (Internal quotation marks omitted.) Matey v.
    Estate of Dember, 
    256 Conn. 456
    , 489, 
    774 A.2d 113
    (2001).
    It is well settled that ‘‘when a commissioner orders
    a medical examination, there is usually an expectation
    among the parties that said examination will provide
    strong guidance to the commissioner. Where a commis-
    sioner chooses not to adopt the diagnosis of the physi-
    cian performing that examination, he or she should
    articulate the reasons behind his or her decision to
    disregard the examiner’s report. . . . [A]lthough a
    commissioner should articulate the reasons behind his
    decision to disregard a § 31-294f examiner’s opinion,
    the ultimate decision is always with the commissioner
    . . . .’’ (Citations omitted; internal quotation marks

    247 Conn. 919
    , 
    722 A.2d 806
     (1998).
    In concluding that the commissioner’s decision ‘‘com-
    plied with the standard . . . delineated for a decision
    which does not rely on the opinion of the commission-
    er’s examiner,’’ the board was necessarily guided by
    § 31-310-3 of the Regulations of Connecticut State Agen-
    cies,15 which governs the requisite content of a commis-
    sioner’s decision. After interpreting the mandates of
    that rule, the board concluded that the commissioner’s
    decision in this case satisfied those requirements. It is
    well settled that ‘‘[an appellate] court affords deference
    to the construction of a statute applied by the adminis-
    trative agency empowered by law to carry out the stat-
    ute’s purposes. . . . [A]n agency’s factual and
    discretionary determinations are to be accorded consid-
    erable weight by the courts.’’ (Internal quotation marks
    omitted.) Bailey v. State,

    , 602–603,

    Contractors, The Learning Corridor, supra, 
    130 Conn. App. 679
     (‘‘[i]t is well established that [a]lthough not
    dispositive, we accord great weight to the construction
    given to the workers’ compensation statutes by the
    commissioner and [the] board’’ [internal quotation
    marks omitted]).
    In light of the foregoing case law and principles,
    which afford considerable deference to the board’s
    interpretation and construction of its own regulations;
    see, e.g., Bailey v. State, supra, 
    65 Conn. App. 602
    –603;
    we conclude that the board did not abuse its discretion
    in not remanding the commissioner’s decision for fur-
    ther articulation.
    The decision of the Workers’ Compensation Review
    Board is affirmed.

    O’Holleran later explained that this second surgery was performed to
    cut away portions of residual scar tissue in the plaintiff’s shoulder, thereby
    reducing stiffness and increasing the range of motion in the left shoulder.

    During the formal hearing before the commissioner, the plaintiff agreed
    with his counsel’s statements that the dolly he used was a ‘‘vertical piece
    of metal with a flat bottom’’ with two wheels in the back, and that, to operate
    the dolly, the operator would place an item on the flat bottom, pull the item
    back toward the vertical piece of metal, and rest the weight of the item on
    the dolly’s wheels.

    General Statutes § 31-294c (a) provides in relevant part: ‘‘No proceedings
    for compensation under the provisions of this chapter shall be maintained
    unless a written notice of claim for compensation is given within one year
    from the date of the accident . . . which caused the personal injury . . . .
    Notice of claim for compensation may be given to the employer or any
    commissioner and shall state, in simple language, the date and place of the
    accident and the nature of the injury resulting from the accident . . . . An
    employee of the state shall send a copy of the notice to the Commissioner
    of Administrative Services. . . .’’
    6
    General Statutes § 31-294f (a) provides in relevant part: ‘‘An injured
    employee shall submit himself to examination by a reputable practicing
    physician or surgeon, at any time while claiming or receiving compensation,
    upon the reasonable request of the employer or at the direction of the
    commissioner. The examination shall be performed to determine the nature
    of the injury and the incapacity resulting from the injury. The physician or
    surgeon shall be selected by the employer from an approved list of physicians
    and surgeons prepared by the chairman of the Workers’ Compensation
    Commission and shall be paid by the employer. . . . The refusal of an
    injured employee to submit himself to a reasonable examination under this
    section shall suspend his right to compensation during such refusal.’’

    During his deposition, O’Holleran testified that a Bankart lesion ‘‘is a
    tear of the labrum [the cartilage that surrounds the socket in the shoulder]
    off of the glenoid in . . . [the] socket.’’ He further testified that a bony
    Bankart lesion is caused ‘‘by the shoulder sliding out of [the] joint either
    partially, which is a subluxation, or fully, which is a dislocation,’’ which
    results in ‘‘an avulsion of the labrum where it takes off a fleck of bone with it.’’
    8
    Dr. Steven E. Selden testified that ‘‘[a] Hill-Sachs lesion is a depression
    in the humeral head that is a result of dislocations of your shoulder, where
    the ball and socket come apart.’’
    9
    O’Holleran described bone marrow edema as ‘‘fluid [in the bone] from
    an injury . . . that goes away a few months after the injury.’’ He further
    testified that, because edema typically subsides after six months, the pres-
    ence of edema in the plaintiff’s shoulder indicated that the plaintiff’s injury
    was new and unrelated either to the 2009 or 2012 surgery.
    10
    At the outset of Selden’s deposition, the following colloquy occurred:
    ‘‘Q. You physically examined [the plaintiff], correct?
    ‘‘A. That is correct as well.
    ‘‘Q. You issued a report . . . and that’s the full report, is it not?
    ‘‘A. Correct.
    ‘‘Q. Since that time, just recently, you have been given a couple of addi-
    tional medical records from the past, which you did not have, correct?
    ‘‘A. That is correct.’’
    Neither the plaintiff nor the defendant inquired as to which additional
    medical records Selden had received and reviewed prior to his December
    2, 2013 deposition.
    11
    Subluxation is the medical term for a partial dislocation of the joint,
    ‘‘where the shoulder goes partly out of place.’’
    12
    Notably, Selden’s written addendum, much like his deposition testimony,
    does not state with any degree of specificity what additional medical records
    he reviewed between his December 2, 2013 deposition and his July 14, 2014
    addendum to his written report. See footnote 10 of this opinion.
    13
    Pursuant to § 31-301-8 of the Regulations of Connecticut State Agencies,
    the board ‘‘considers no evidence other than that certified to it by the
    commissioner, and then for the limited purpose of determining . . .
    whether there was any evidence to support in law the conclusion reached.
    It cannot review the conclusions of the commissioner when these depend
    upon the weight of the evidence and the credibility of witnesses. . . .’’
    (Emphasis added.)
    14
    Since the Bode decision, the board has held: ‘‘We do not believe Bode
    . . . has limited such precedents as [O’Reilly v. General Dynamics Corp.,
    supra, 
    52 Conn. App. 813
    ] as to the trial commissioner’s prerogative to
    assess and weigh medical evidence. A trial commissioner is not obligated
    to accept the most recent medical opinion presented to the tribunal. . . .
    However, when a medical witness offers subsequent testimony which devi-
    ates from a prior opinion, a trial commissioner must acknowledge and
    reconcile the differing opinions and should the commissioner seek to rely
    on the prior opinion, grounds for the reliance must be provided.’’ (Citation

    Section 31-301-3 of the Regulations of Connecticut State Agencies pro-
    vides: ‘‘The finding of the commissioner should contain only the ultimate
    relevant and material facts essential to the case in hand and found by him,
    together with a statement of his conclusions and the claims of law made
    by the parties. It should not contain excerpts from evidence or merely
    evidential facts, nor the reasons for his conclusions. The opinions, beliefs,
    reasons and argument of the commissioner should be expressed in the
    memorandum of decision, if any be filed, so far as they may be helpful in
    the decision of the case.’’
