    WORKERS’ COMPENSATION BOARD; AND
    HONORABLE CHRISTINA D. HAJJAR,
    ADMINISTRATIVE LAW JUDGE
    MEMORANDUM OPINION OF THE COURT
    AFFIRMING
    Barbara Smith filed a workers’ compensation claim alleging both a single
    work-related injury and a cumulative trauma injury stemming from her work
    as a coal miner for thirty years. The Administrative Law Judge (ALJ), having
    heard the evidence and legal arguments, dismissed both claims. The Workers’
    Compensation Board (Board) and the Court of Appeals affirmed, finding
    substantial evidence supported the ALJ’s determination that Smith did not
    sustain work-related injuries. On appeal, Smith argues that the ALJ failed to
    accurately analyze the evidence and rendered a decision that does not conform
    with applicable Workers’ Compensation laws. Finding no error, we affirm.
    FACTS AND PROCEDURAL HISTORY
    Barbara Smith began work as a coal miner in 1984 and started working
    for Bledsoe Coal Company in 1999. Smith served as a safety director and
    routinely checked oxygen tanks located in various places throughout the mine.
    She stated that oxygen tanks are stored underground for safety reasons, such
    as lack of oxygen to the area, and the tanks were checked quarterly. On
    September 11, 2014 Smith was walking on a crossover, which allows people to
    get to the other side of the conveyor belt, and a step broke, causing her to fall.
    She twisted around and hit the ground, falling flat on her back and landing on
    her rescuer - a six-by-eight oxygen unit about four inches thick with steel
    casing. It was located at her hip on her belt. She rolled over on her stomach,
    caught her breath and stood up. She said she could not breathe and felt like
    her insides were swelling.
    After leaving the mines, Smith went to the office, reported the injury and
    filled out an accident report. She was taken to the company doctor, Dr.
    Dahhan, who x-rayed her ribs and confirmed they were not broken. Smith
    testified that a few days after the accident she had a bruise on the upper
    portion of her right hip and backside. Smith returned to work on September
    12, 2014 and continued to work until she was laid off on December 31, 2014.
    A new coal company took over the coal mine and Smith was informed that she
    was no longer needed. Smith did not miss a single day of work between
    September 11 and December 31, 2014. After being laid off, she applied for,
    and received, unemployment benefits.
    2
    At the end of 2015 Smith began experiencing issues with her right knee
    and soon discovered that her pain stemmed from a back problem. She denied
    having any pain in her leg or knee prior to the work accident. In April 2016
    she saw Denise Bunner, APRN, and her chief complaints were back and right
    leg pain. Bunner assessed acute right-sided low back pain with radiculopathy
    and prescribed pain medication. Bunner also ordered an MRI of the lumbar
    spine and referred Smith to a neurosurgeon. Dr. Jeffrey Jones read the MRI of
    Smith’s lumbar spine taken on May 6, 2016 and noted degenerative disc
    disease from L3 to SI. The MRI also suggested disc space narrowing with
    minor bulging and spinal stenosis.
    Bunner referred Smith to Dr. David Eggers who examined Smith on June
    13, 2016. Her chief complaint was back and right leg pain she claimed to
    experience since the 2014 work accident. Dr. Eggers performed a laminectomy
    at the L3-L4 level and discovered a massive cyst that was not visible on the
    MRI.1 The surgery was successful, and during a post-surgery evaluation Smith
    reported that her right leg pain was completely gone, and she had some relief
    from her low back pain. Bledsoe’s workers’ compensation carrier paid for the
    first MRI and surgery but declined to pay for any additional treatment.
    1 “Laminectomy is a surgery that creates space by removing the lamina - the
    back part of a vertebra that covers the spinal canal. Also known as decompression
    surgery, laminectomy enlarges the spinal canal to relieve pressure on the spinal cord
    or nerves.” Laminectomy, Mayo Clinic (June 13, 2018),
    https://www.mayoclinic.org/tests-procedures/laminectomy/about/pac-20394533.
    3
    On December 12, 2016, six months post-operation, Dr. Eggers noted that
    the pain switched between her left and right legs. Smith had several follow-up
    visits with Dr. Eggers and continued reporting leg and hip pain. He performed
    another laminectomy surgery on January 24, 2017 at the L4-L5 level. Dr.
    Eggers noted that Smith reported being better for about a week following the
    surgery, but still reported pain in her right leg. The last time Dr. Eggers saw
    Smith was on April 19, 2017. The results of a myelogram did not show any
    nerve compression and Dr. Eggers wondered whether Smith had a problem
    with her hip joint and recommended an orthopedic examination.
    Dr. Bailey Phelps saw Smith for the first time in December 2016 for pre-
    operative clearance for her second surgery after she was diagnosed with Type-II
    diabetes. On March 30, 2017 Dr. Phelps examined Smith and noted that she
    limps, favoring her left hip. After examining the April 2016 MRI of the lumbar
    spine, Dr. Phelps noted moderate to severe degenerative disc disease,
    spondylosis and stenosis. She opined that these diagnoses were consistent
    with “wear and tear” arthritis and cumulative trauma, but also stated that
    Smith being overweight could contribute to her complaints. She also noted
    that physical and manual labor can contribute to chronic back pain and
    arthritis, as shown on Smith’s MRI. Dr. Phelps referenced the July 2016
    surgery and stated that it fully alleviated Smith’s radicular pain, suggesting
    that the pain Smith experienced during the March 30, 2017 visit was a result
    of the work injury.
    4
    On January 17, 2017 Smith filed a claim with the Department of
    Workers’ Claims (DWC) alleging she injured her low back in the fall at work.
    On February 21, 2017, Bledsoe filed a response and motion to dismiss the
    claim, alleging that Smith failed to file her claim within the applicable two-year
    statute of limitations, among other things. On March 10, 2017, the ALJ issued
    an order passing the statute of limitations argument to consideration of the
    merits of the claim. Smith filed a motion to amend her claim on April 5, 2017
    to include a to cumulative trauma injury from working in the coal mines from
    1984 through December 31, 2014.
    At her deposition on April 3, 2017, Smith testified that she is still not
    able to use her right leg and continues to have radiating pain. She experiences
    the pain most often at night when she is trying to rest, and if she sits too long
    or walks too much. She now uses a cane to walk. Smith testified that she
    asked Dr. Eggers if the cyst he discovered during the first surgery was related
    to her work in the mines, and he said “probably.” Smith prepared an affidavit
    stating that she continued her ordinary work duties until December 31, 2014.
    She worked in and around underground mines which involved pushing,
    pulling, bending, stooping, lifting, shoveling and stairclimbing, even though she
    admitted experiencing some soreness.
    Dr. David Muffly conducted an independent medical examination (IME)
    of Smith on May 31, 2017. Smith primarily complained of right buttock pain
    and right thigh weakness, noting that her symptoms were worse at the end of
    the day and increased with prolonged sitting or prolonged walking. She
    5
    reported that she could not walk more than fifteen minutes or lie on her right
    side. She also stated that she had difficulty bending, lifting and twisting.
    Dr. Muftly diagnosed chronic low back pain referred into the right leg
    after low back injury with minimal improvement post-surgical intervention,
    multiple level degenerative disc disease, and spinal and neuroforaminal
    stenosis. He opined that the work injury and cumulative trauma caused
    Smith’s impairment. Dr. Muffly opined that Smith reached maximum medical
    improvement on May 31, 2017. He stated that Smith had restricted range of
    motion in her lumbar spine and assigned a whole person impairment of 26%,
    using the range of motion method of assessing her lumbar spine. Dr. Muffly
    apportioned 50% of this impairment to the September 11, 2014 work injury
    and 50% to cumulative trauma caused by her occupation. He also opined that
    Smith’s degenerative changes and spinal stenosis are more than expected for
    someone her age. He recommended permanent restrictions of lifting/carrying
    no more than fifteen pounds, limited distance walking up to ten minutes at a
    time, limited sitting thirty minutes at a time, and no bending or stooping. Dr.
    Muffly did not believe Smith could return to her coal mining occupation.
    Dr. Timothy Kriss conducted an IME on June 7, 2017. During the
    examination, Smith reported her current symptoms as right-sided low back
    pain, right thigh pain, and being unable to walk at times due to pain. Dr. Kriss
    stated that Smith attributed all her symptoms to the September 11th work
    injury. However, when specifically questioned she did state that in addition to
    6
    the work injury she believed that working in the mines for thirty years
    contributed to her current pain.
    Dr. Kriss opined that the complete absence of any need for medical
    treatment for low back, right hip, thigh or knee pain for so long after the
    September 11, 2014 accident indicates that these symptoms cannot possibly
    be attributed to Smith’s fall at work.2 After reviewing Smith’s medical and
    treatment history Dr. Kriss noted that Smith complained of pain in her chest
    after her fall, and Dr. Dahhan noted that she had full range of motion in all
    major joints. Additionally, although Smith sought treatment for knee and leg
    pain in 2016, she stated the pain had only been present for two months and
    did not complain of any low back pain at the time. Dr. Kriss concluded that
    the injury did not cause her current complaints or cause the complaints for
    which she underwent surgery in 2016, and that Smith’s back condition is not
    related to work in any way.
    Dr. Kriss stated that there is no evidence of a cumulative, repetitive,
    incremental work-related injury to Smith’s lumbar spine, hip or lower
    extremities. He opined that there is zero evidence of work-related etiology so
    certain as to be within a reasonable degree of medical probability. He cited
    twin studies indicating that a twin with a history of occupational exposure to
    2 Dr. Kriss’s report actually states that Smith did not seek treatment for twenty
    one months after the September 11th injury, and during that medical visit she stated
    she experienced the knee pain for two months. He lists a January 2016 visit with an
    APRN and Dr. Phelps. Therefore, it was actually sixteen months after the injury that
    she sought treatment for knee pain. This discrepancy in the calculation of months is
    harmless.
    7
    lifting, twisting and awkward postures did not result in any more lumbar
    degeneration than the twin with little or no such exposure. He further stated
    that Smith’s spine degeneration is within normal range for her age.
    Dr. Kriss stated that Smith remains highly symptomatic in her right hip
    and that he would not return her to work at this time. He opined that even
    though she needed an orthopedic evaluation and treatment, the treatment
    would not be related to her work injury. According to Dr. Kriss, Smith reached
    maximum medical improvement on January 11, 2015 from the temporary
    musculoskeletal strain/contusion stemming from the September 11, 2014
    work accident.
    The ALJ relied on Dr. Kriss in concluding that Smith sustained a
    temporary musculoskeletal strain/contusion on September 11, 2014, but that
    there was no compensable injury. The ALJ also determined that the work
    accident did not cause Smith’s low back, hip and leg complaints for which she
    underwent surgery. The ALJ was not convinced that cumulative trauma
    caused or hastened the degenerative conditions in Smith’s low back. Smith
    was able to work full-time, full duty until she was laid off and did not have
    back complaints until over a year after she stopped working for Bledsoe.
    The ALJ recognized Dr. Eggers’ opinion that heavy manual labor, like the
    labor performed by Smith, hastens lumbar degenerative disease, and that Dr.
    Phelps opined that Smith’s results were consistent with cumulative trauma.
    However, the ALJ determined that none of these doctors addressed the issues
    raised by Dr. Kriss, such as the fact that Smith worked full time with no back
    8
    or leg complaints until more than one year after she stopped working.
    Therefore, Smith did not meet her burden of proving a single work-related
    injury or a cumulative trauma injury and both claims were dismissed
    accordingly. The ALJ also determined that because Smith did not file her claim
    within two years of the September 11, 2014 injury her claim is barred by the
    statute of limitations. Smith filed a petition for reconsideration which was
    denied.
    Smith appealed to the Workers’ Compensation Board. The Board first
    reviewed the ALJ’s dismissal based upon Smith’s failure to timely file her claim
    and expressed concern over whether notice and filing requirements pursuant to
    KRS 342.038, 342.040 and 342.185 were satisfied. However, the ALJ also
    dismissed Smith’s claims for both the acute and cumulative trauma injuries
    based upon the merits of the claim. Therefore, the ALJ’s finding regarding the
    procedural dismissal of the claim based on the statute of limitations at most
    was harmless error. The Board also concluded that the evidence does not
    compel a finding that Smith sustained a permanent injury either from her fall
    or from her thirty years working as a coal miner. The Board specifically
    pointed to the fact that although Smith received treatment from Dr. Dahhan
    after the accident, there is no evidence that any additional treatment was
    sought until April 2016. The Board affirmed the ALJ’s opinion and order.
    Smith appealed to the Court of Appeals. The Court of Appeals agreed
    with the Board’s conclusions on the merits of the case and declined to address
    the statute of limitation issue. The Court of Appeals found that the ALJ
    9
    understood all evidence before she rendered her opinion and that the ALJ was
    simply more persuaded by Bledsoe’s evidence, primarily Dr. Kriss’s report. In
    affirming the Board’s decision, the Court of Appeals concluded that the medical
    evidence supported the ALJ’s legal conclusion regarding causation. Smith now
    appeals to this Court.
    ANALYSIS
    This case involves two “injuries” - the injury stemming from the
    September 11th work accident and a cumulative trauma injury stemming from
    Smith’s thirty years employed as a coal miner. We note that the ALJ dismissed
    Smith’s claim regarding the September 11th work injury based on the two-year
    statute of limitations but also because there was insufficient evidence that
    Smith’s fall caused her complaints leading to treatment or that she sustained
    any permanent injury from the fall. Kentucky Revised Statute (KRS)
    342.185(1) provides
    Except as provided in subsections (2) and (3) of this section,
    no proceeding under this chapter for compensation for an injury or
    death shall be maintained unless a notice of the accident shall
    have been given to the employer as soon as practicable after the
    happening thereof and unless an application for adjustment of
    claim for compensation with respect to the injury shall have been
    made with the department within two (2) years after the date of the
    accident ....
    According to KRS 342.185(1), Smith had two years from September 11,
    2014 to file her claim.3 She did not file the claim until January 17, 2017, well
    3 Throughout these proceedings the parties have only discussed the statute of
    limitations issue as it pertains to the single work-related injury claim, 2014, not the
    cumulative injury claim.
    10
    beyond the two-year statute of limitations. In response to Bledsoe’s motion to
    dismiss based on the statute of limitations, Smith argued that Bledsoe never
    notified the DWC as required by KRS 342.038(1), which requires an employer
    to keep record of all employee injuries received in the course of employment.
    The statute further requires that
    [w]ithin one week after the occurrence and knowledge ... of an
    injury to an employee causing his absence from work for more
    than one (1) day, a report thereof shall be made to the department
    in the manner directed by the commissioner through
    administrative regulations.
    The Board was troubled by the ALJ’s dismissal based on the statute of
    limitations, noting the complexity of the case, questioning whether Bledsoe
    provided notice to the DWC pursuant to KRS 342.038, and considering
    whether the statute of limitations should have been tolled. However, the Board
    concluded that because the ALJ also dismissed Smith’s claim on the merits,
    any error in the finding regarding procedural dismissal was harmless. The
    Court of Appeals agreed with the ALJ on the merits of the claim and declined to
    review the statute of limitations issue.
    The Board noted that failure to fulfill the requirements of KRS 342.038
    and KRS 342.040(1) requires a determination of whether the two-year statute
    of limitations should be tolled. KRS 342.040(1) states in part:
    ... If the employer's insurance carrier or other party responsible
    for the payment of workers' compensation benefits should
    terminate or fail to make payments when due, that party shall
    notify the commissioner of the termination or failure to make
    payments and the commissioner shall, in writing, advise the
    employee or known dependent of right to prosecute a claim under
    this chapter.
    11
    In J & VCoal Co. v. Hall, 
    62 S.W.3d 392
    , 394-95 (Ky. 2001), this Court
    considered how these statutes work together for use in assessing whether a
    claim is time barred:
    KRS 342.185 provides that a claim must be filed within two
    years of the date of accident or within two years of the last
    payment of voluntaiy income benefits, whichever is later. It has
    long been recognized that KRS 342.185 operates together with KRS
    342.040(1) and tolls the period of limitations until after the
    payment of voluntary income benefits ceases in order to protect
    injured workers from being lulled into a false sense of security by
    receiving such payments and, therefore, failing to actively pursue a
    claim. See City of Frankfort v. Rogers, Ky. App., 
    765 S.W.2d 579
    ,
    580 (1988). Likewise, KRS 342.040(1) clearly requires an employer
    who fails to pay income benefits that are due to notify the
    commissioner of such failure. An employer who fails to comply
    with KRS 342.040(1) is not permitted to raise a limitations defense
    because its action effectively prevents the commissioner from
    complying with its duty under KRS 342.040(1) to notify the worker
    of his right to prosecute a claim and of the applicable period of
    limitations.
    Id. By requiring an
    employer to file a Form SF-1 when
    an injured worker misses one day of work due to a work-related
    injury, KRS 342.038(1) puts the employer on record as admitting
    the existence of the injury. This prevents the employer from later
    manufacturing a limitations defense by denying knowledge of the
    injury and asserting, therefore, that it had no obligation under
    KRS 342.040(1) to notify the commissioner that it either
    terminated or failed to pay income benefits that were due.
    According to Smith’s own testimony, she did not miss any work because
    of the work accident. She testified that she did not miss a single day of work
    from September 11, 2014 until she was laid off by Bledsoe on December 31,
    2014. So, it appears that because Smith did not miss work, the filing
    requirement of KRS 342.038(1) is not triggered. This Court analyzed KRS
    342.038 in H.E. Neumann Co. v. Lee, 
    975 S.W.2d 917
    , 920 (Ky. 1998), and
    stated that “once the employer herein had notice that claimant had missed
    more than one day of work as the result of an alleged work-related injury, it
    12
    had the duty of filing a first report of injury with the board within one week.”
    Here, Smith missed no work because of the September 11th incident so
    Bledsoe was not under any obligation according to KRS 342.038 to file an
    injury report with the DWC, and Smith was not entitled to notice of her right to
    prosecute a claim under KRS 342.040.
    In H.E. Neumann Co., this Court further reasoned that “when the
    employer failed to make voluntary payments after claimant was absent from
    work for seven days, it had the duly of notifying the board that no benefits
    would be paid so that the board could notify claimant regarding the applicable
    statute of 
    limitations.”4 975 S.W.2d at 920
    . Again, Smith did not miss any
    work because of the September 11th incident, rendering this statute
    inapplicable. Further, no payments were due under KRS 342.040(1) because
    there was no agreement or adjudication requiring benefits payments, rendering
    this statute inapplicable.5 While Smith correctly states that a statute of
    limitations can be tolled if an employer fails to comply with the notice
    4 In H.E. Neumann Co., the Court cited the 1990 version of KRS 342.040, which
    placed an obligation on the employer to notify the board of any termination of benefits
    payments. The current version of this statute requires notice to the Commissioner of
    the Department of Workers’ Claims.
    5 See Fox v. Sam’s Club, 
    2015 WL 9243864
    , No. 2015-SC-000136-WC, (Ky. Dec.
    17, 2015), where this Court explained that KRS 342.040(1) does not compel an
    employer to pay voluntary permanent partial disability (PPD) benefits after a period of
    disability has passed. The statute instead describes the time period for which PPD
    benefits are to be paid and imposes penalties if those requirements are not met.
    Id. at *2.
    “Our Workers’ Compensation Act does not impose a duty to pay permanent
    income benefits absent ALJ approval of a Form 110 settlement agreement pursuant to
    KRS 342.265(1), or until after the filing of a Form 101 when liability is dictated by the
    award in an ALJ Opinion.”
    Id. 13
    requirements of KRS 342.038 and KRS 342.040, tolling is inapplicable here
    because no notice requirements were triggered.
    The Board’s opinion states that “[ajrguably, when Bledsoe paid for that
    surgery, an obligation was created to file a notification with the Kentucky
    Department of Workers’ Claims that it was denying or refusing to pay TTD
    benefits, which may result from recovery from the surgery.” The Board noted
    that there was no evidence that Bledsoe was ever presented with a request for
    payment of TTD benefits. Regardless of a request, this payment for a surgery
    does not constitute an “income benefit” under KRS 342.0011. Instead, it is a
    medical benefit. Both definitions are outlined in KRS 342.0011, which states:
    (12) “Income benefits” means payments made under the
    provisions of this chapter to the disabled worker or his dependents
    in case of death, excluding medical and related benefits;
    (13) “Medical and related benefits” means payments made for
    medical, hospital, burial, and other services as provided in this
    chapter, other than income benefits;
    In sum, Smith did not miss any work because of the accident, did not
    receive voluntary income benefits from Bledsoe, and showed no signs of injuiy
    or impairment from September 11, 2014 through her last day of work with
    Bledsoe. As a result, Bledsoe was not required to provide any notice to the
    DWC. Therefore, the ALJ properly concluded that Smith’s claim for the single
    work-related injury on September 11, 2014 was barred by the statute of
    limitations.
    The Board and the Court of Appeals were ambiguous in their treatment
    of the statute of limitations issue. However, both held that even if the ALJ’s
    determination regarding the statute of limitations was erroneous it was
    14
    harmless because the ALJ dismissed Smith’s single injury claim based on the
    medical evidence of record. In any event, we recognize that the ALJ, the Board
    and the Court of Appeals primarily focused on the underlying merits of Smith’s
    claims in reaching their decisions. Therefore, we proceed to discuss the issues
    regarding the merits of the claim.
    Smith argues that the ALJ failed to accurately analyze the evidence and
    that the decisions of the reviewing authorities thus far do not conform with the
    Workers’ Compensation Act and precedent. On appellate review, this Court
    must determine whether substantial evidence of probative value supports the
    ALJ’s findings. Whittaker v. Rowland, 
    998 S.W.2d 479
    , 481-82 (Ky. 1999).
    Substantial evidence is evidence of “substance and relevant consequence”
    having fitness to induce conviction in the minds of reasonable people. Miller v.
    Tema Isenmann, Inc., 
    542 S.W.3d 265
    , 270 (Ky. 2018); see also Gray v.
    Triinmaster, 
    173 S.W.3d 236
    , 241 (Ky. 2005) (if the ALJ finds against the party
    having the burden of proof, the appellant must “show that the ALJ misapplied
    the law or that the evidence in her favor was so overwhelming that it compelled
    a favorable finding”). In dismissing Smith’s claims, the ALJ primarily relied on
    the report of Dr. Kriss. Smith argues that the ALJ misinterpreted the medical
    evidence and improperly relied on opinions that were formed based on false
    and incorrect medical information. We now consider whether these medical
    opinions constitute substantial evidence for each of the alleged injuries.
    15
    I.      The single work-related low back injury on September 11, 2014
    After considering all the evidence, the ALJ primarily relied on Dr. Kriss’s
    evaluation and report. Upon review of his report, we agree with the Court of
    Appeals that this evidence satisfies our standard on appeal. Dr. Kriss, a
    neurosurgery and spine specialist, performed an independent medical
    examination on June 7, 2017. Dr. Kriss reviewed all relevant medical records
    and radiology reports. During the examination, Smith reported right-sided low
    back pain, right thigh and knee pain, and right hip pain. She also stated she
    was unable to walk more than fifty feet without experiencing pain and claimed
    to have very little muscle in her right leg. Notably, Smith attributed all her
    symptoms to the September 11th work injury. Upon prompting, Smith
    admitted that working in the mines for thirty years contributed to her current
    complaints.
    Dr. Kriss opined that some sort of degenerative pathology in Smith’s right
    hip is responsible for the bulk of her complaints and is causing a lot of the pain
    she experiences in her right thigh and knee. He recommended that an
    orthopedic surgeon evaluate Smith in hopes that a routine surgical procedure
    on the right hip would alleviate most, if not all, of the pain in the right hip,
    thigh and knee.
    Dr. Kriss noted that, contrary to what Smith told him during the IME,
    there is no documented low back pain on September 11, 2014. Dr. Dahhan
    localized her pain to her right anterior chest, which is in the thoracic part of
    the spine - not the lumbar. Dr. Kriss also highlighted the fact that Dr. Dahhan
    16
    ordered imaging of Smith’s chest and right ribs, not the lumbar spine, pelvis or
    hips where her pain currently resides. If a traumatic injuiy to the lumbar
    spine was truly responsible for the hip weakness she experiences, then there
    should have been at least some hip pain or weakness on September 11th and
    none was reported or recorded.
    Smith did not seek medical treatment for a considerable period following
    her injuiy,6 and notably continued to work full-time and full-duty in a
    physically demanding coal mining position. Smith first sought medical
    treatment after the work accident for right knee pain and did not complain of
    low back pain at the time. Dr. Kriss explained that there is no connection
    between the knee and the lumbar spine. He opined that there was no way this
    lower extremity complaint in 2016 could be related to a single traumatic event
    that occurred in September 2014. Further, Dr. Kriss stated that Smith’s pain
    at the time of the IME was completely different than the pain which prompted
    the first surgery by Dr. Eggers.
    Dr. Kriss summarized the medical evidence and his evaluation regarding
    the September 11, 2014 work accident as follows:
    In other words, Ms. Smith’s (L4) distribution pain today is
    completely different than the distribution which prompted Dr.
    Eggers to decompress Ms. Smith on July 26, 2016.
    Nor does Ms. Smith ever demonstrate a positive right hip
    orthopedic examination to any of the medical professionals who
    examine her in the two years immediately after September 11,
    2014.
    With the complete absence of any low/lumbar back pain,
    any right hip pain, any pelvic pain, any thigh pain, on September
    6 See n.2.
    17
    11, 2014 and for the next 21 months thereafter, these symptoms
    in the lumbar spine and right hip cannot be attributed to the
    September 11, 2014 fall at work.
    When Ms. Smith finally does develop right knee pain for the
    first time ever 16 months after September 11, 2014, that knee pain
    has only been present two months and is not associated with any
    trauma. Therefore the knee pain cannot be from the fall on
    September 11, 2014.
    With the complete absence of any need for medical
    evaluation or treatment for low back, right hip, pelvis, right thigh
    or traumatic right knee pain for 21 months after September 11,
    2014, when the symptoms finally do manifest so markedly delayed,
    they cannot possible be attributed to the September 11, 2014 fall
    at work.7
    As fact finder, the ALJ has the sole authority to determine the weight,
    credibility and substance of the evidence. Square D Co. v. Tipton, 
    862 S.W.2d 308
    (Ky. 1993). Mere evidence to the contrary is insufficient to require reversal
    on appeal, 
    Whittaker, 998 S.W.2d at 479
    , because as the party with the burden
    of proof Smith must show the evidence was so overwhelming that it compelled
    a finding in her favor. Special Fund v. Francis, 
    708 S.W.2d 641
    , 643 (Ky.
    1986). Here, the evidence does not compel a finding that Smith sustained a
    permanent injury from the September 11, 2014 accident. Although Smith
    complained of back pain in her initial visit with Dr. Dahhan, there is no
    indication that he treated her for such. Additionally, there is no evidence that
    any additional treatment for back pain was sought in the remaining three and
    7 Again, we reiterate that there may have been a clerical error in Dr. Kriss’s
    calculation of time periods since the September 11, 2014 work accident. It was
    actually sixteen months after the accident that Smith sought treatment for right knee
    pain.
    18
    a half months of her employment with Bledsoe. The earliest indication that
    Smith sought treatment for back pain was in April 2016.
    The ALJ provided thorough reasoning to support her conclusion, and
    specifically stated the information she relied on in reaching the result. The ALJ
    noted that Smith’s testimony was convincing, in that she had a bruise on her
    right upper hip and backside following the injuiy. Additionally, the ALJ stated
    that she considered the opinions of Drs. Phelps, Muffly and Eggers but found
    that they related the work injury to Smith’s complaints based on Smith’s
    subjective history of progressive complaints of pain following the fall. The ALJ
    concluded that Smith’s medical records did not support her claim that she had
    progressive complaints of leg and low back pain. Dr. Eggers agreed that it was
    not medically probable that the fall caused any injuiy if the fall occurred years
    ago and there were no ongoing problems stemming from the incident. Because
    the ALJ’s opinion and order was supported by substantial evidence, no error
    occurred.
    II.     Cumulative trauma injury from thirty years of coal-mining
    Smith amended her workers’ compensation claim to include allegations
    that her low back and radiating pain into her leg and hip were caused by
    cumulative trauma from her work as a coal miner over the course of thirty
    years. As the claimant, Smith bears the burden of proving every element of a
    workers’ compensation claim. Magic Coal Co. v. Fox, 
    19 S.W.3d 88
    , 96 (Ky.
    2000). This includes medical causation, which must be proved to a reasonable
    19
    medical probability with expert medical testimony. Brown-Forman Corp. v.
    Upchurch, 
    127 S.W.3d 615
    , 621 (Ky. 2004).
    The Court first recognized the compensability of injuries that resulted
    from cumulative trauma or gradual wear and tear in 1976. Haycraft v. Corhart
    Refractories Co., 
    544 S.W.2d 222
    (Ky. 1976). Where an individual continues to
    perform the same repetitive activity after a gradual injury becomes manifest,
    additional incidents of workplace trauma may well cause additional harmful
    changes. Special Fund v. Clark, 
    998 S.W.2d 487
    (Ky. 1999). In other words,
    the individual may sustain subsequent gradual injuries. Smith was tasked
    with proving medical causation and demonstrating that her injuiy is a result of
    repetitive, gradual trauma from her work as a coal miner.
    The ALJ relied on Dr. Kriss in finding that Smith failed to prove that her
    complaints are due to cumulative trauma. Dr. Kriss concluded that “there is
    literally zero evidence of a cumulative/repetitive/incremental work-related
    injury to Ms. Smith’s lumbar spine, hip or lower extremities. Zero.” He also
    stated that back pain cannot result from cumulative trauma if there is no
    accumulation of back pain. Dr. Kriss explained that because no medical
    documentation exists to even suggest work-related causation, there is no way
    to distinguish a person with spine pain caused by any reason other than work
    and a person with spine pain caused by their employment. His report was
    detailed and thorough and adequately supports the ALJ’s conclusion that
    Smith did not sustain a cumulative work-related injury.
    20
    Smith argues that Dr. Kriss’ report was based on false information
    because the report contained an incorrect history of the injury from Dr.
    Dahhan, who insisted on diagnosing a chest injury despite the history he was
    given. She suggests either that Dr. Dahhan failed to record her low back
    complaints during the visit and/ or failed to provide competent care by not
    treating her for low back complaints. Smith points to nothing specific in Dr.
    Dahhan’s notes that suggests he had an incorrect history or failed to treat her
    for her complaints. If the records were inaccurate Smith could have addressed
    the error by providing additional testimony such as correspondence from Dr.
    Dahhan or a deposition. Smith is correct in noting that a physician cannot
    base his opinion on patient history that is “substantially inaccurate or largely
    incomplete.” Cepero v. Fabricated Metals Corp., 
    132 S.W.3d 839
    , 842 (Ky.
    2004). However, Smith has pointed to nothing else in the record showing that
    Dr. Kriss relied on inaccurate or incomplete history, other than the alleged
    insufficiencies with Dr. Dahhan’s treatment report. This simply does not rise
    to the level of error recognized in Cepero.
    As with most workers’ compensation cases, this case involves conflicting
    medical opinions and reports. Smith argues that the ALJ discounted and
    misconstrued the medical evidence, but we disagree. In her opinion the ALJ
    demonstrated that she thoroughly considered and reviewed all medical
    evidence in the record. Dr. Eggers testified that Smith reported back pain
    since 2014 stemming from the fall at work. He stated that falling on a rescuer
    device is sufficient to result in back pain, and that manual labor like working
    21
    as a coal miner can hasten degenerative disease. Dr. Eggers also admitted that
    it is not medically probable that the fall caused the injury if the fall occurred
    years earlier and there were no ongoing back problems.
    Additionally, Dr. Muffly examined Smith and provided testimony in
    Smith’s favor and assessed a permanent impairment, both from the single work
    accident and cumulative injury. Dr. Phelps opined that Smith’s symptoms
    were consistent with cumulative trauma. The ALJ explained that she
    considered these doctors’ opinions but chose not to rely on them because they
    based their opinions regarding causation on Smith’s subjective history that her
    complaints began after her fall at work, despite contradiction in her medical
    records. It is clear that the ALJ considered this evidence but nonetheless
    concluded that Smith failed to meet her burden of proving work-related
    cumulative trauma.
    “An ALJ may reject any testimony and believe or disbelieve various parts
    of the evidence .... The mere existence of evidence that would have supported
    a different decision is an inadequate ground for reversal on appeal.” American
    Greetings Corp. v. Bunch, 
    331 S.W.3d 600
    , 602 (Ky. 2010). Further, “[wjhere
    there is conflicting medical testimony concerning the cause of a harmful
    change, it is for the ALJ to weigh the evidence and decide which opinion is the
    most credible and reliable.” 
    Brown-Forman, 127 S.W.3d at 621
    . The ALJ
    acknowledged the contrary medical evidence and competing opinions and
    appropriately weighed her decision. We agree with the Court of Appeals that
    22
    the opinion of Dr. Kriss provides a sufficient evidentiary basis to support the
    ALJ’s conclusions.
    CONCLUSION
    After review of the record, we find that substantial evidence supported
    the ALJ’s findings. For the foregoing reasons, we affirm the Court of Appeals
    decision, which affirmed the Board’s decision.
