Appellant Charles Frances filed a claim for workers’ compensation benefits, alleging that he suffered a compensable back injury while working for appellee Gaylord Container on September 23, 1996. The ALJ found the claim to be compensable, and ordered the appellee to cover related medical expenses and pay temporary total disability benefits from September 3, 1997, through January 7, 1998. However, on appeal to the Workers’ Compensation Commission, the Commission reversed the decision of the ALJ and awarded no benefits pursuant to its finding that Mr. Frances failed to prove that his back condition was the result of any work-related incident. Mr. Frances now appeals, arguing that the Commission’s decision is not supported by substantial evidence. We agree, and we reverse and remand for an award of benefits.
When the Commission denies coverage because the claimant failed to meet his burden of proof, the substantial-evidence standard of review requires that we affirm the Commission’s decision if its opinion displays a substantial basis for the denial of relief. McMillan v. U.S. Motors, 59 Ark. App. 85, 953 S.W.2d 907 (1997). In determining the sufficiency of the evidence to sustain the findings of the Commission, we review the evidence in the light most favorable to the Commission’s findings and affirm if they are supported by substantial evidence. Weldon v. Pierce Bros. Constr., 54 Ark. App. 344, 925 S.W.2d 179 (1996). Substantial evidence is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion. City of Fort Smith v. Brooks, 40 Ark. App. 120, 842 S.W.2d 463 (1992). The question is not whether the evidence would have supported findings contrary to the ones made by the Commission; there may be substantial evidence to support the Commission’s decision even though we might have reached a different conclusion if we sat as the trier of fact or heard the case de novo. Tyson Foods Inc. v. Disheroon, 26 Ark. App. 145, 761 S.W.2d 617 (1988).
Brian Hamblin, a co-worker of Mr. Frances and employee of Gaylord Container for eight-and-one-half years, testified about the alleged September 23, 1996, incident. Mr. Hamblin stated that, on that day, a paper machine heated up and a sheet broke, and apparently Mr. Frances went to fix the problem. About twenty minutes later, Mr. Frances told him that, while attending to the paper machine, he was “hit by the scanner” and was “pinched in the machine.” When Mr. Frances told Mr. Hamblin about being injured, Mr. Hamblin noticed that the back of his shirt was ripped and he had a cut on his arm. When asked if he was going to go to the doctor, Mr. Frances replied, “No, I think it’s all right.” However, according to Mr. Hamblin, Mr. Frances filled out an accident report with the foreman. Mr. Frances continued working, but two or three days later he told Mr. Hamblin that his back was still hurting and “once or twice he just laid up on the counters.” Mr. Hamblin testified that, after the accident, Mr. Frances would limp around at work and that he had never known him to do- that before.
Randy Womack, an employee of four years, was also working on the day of the alleged accident. He testified that “when he came out around the back of the machine, his arm was bleeding and his shirt was torn, and he told me that the scanner had caught him.” About three days later, Mr. Frances complained to Mr. Womack of back pain and numbness in his leg.
Bobby Young, Mr. Frances’s auto mechanic, testified that in November 1996 Mr. Frances brought his car in and was walking crooked and complaining of hurting his back at work. Mr. Young had been his mechanic for ten years and had never seen him in this condition.
Mr. Frances testified on his own behalf, and he stated that he had been employed with the appellee and its predecessors since 1963. He gave an account of the paper scanner striking him, causing him to twist to the floor in an awkward motion to avoid being seriously injured. Although he was in pain, he continued to work until mid-November when he missed two days of work because his condition became intolerable. He first sought medical treatment on December 2, 1996, from Dr. Clyde Paulk. Dr. Paulk referred him to Dr. Robert Dickins, who performed an MRI and diagnosed a possible herniation. Mr. Frances then underwent conservative treatment, including physical therapy, and continued to work his regular work schedule. However, when his back condition failed to improve, he underwent surgery on September 3, 1997, which forced him to remain off work until January 7, 1998.
The testimony revealed that a meeting was held between Mr. Frances and his supervisors in January 1997. The gist of the meeting was to assess his medical treatment plan. He had been paying for medical care through his health insurance, and was told that if he filed a workers’ compensation claim, it would probably be denied and that the insurance might stop paying. Apparently, it was suggested to Mr. Frances that he fill out some forms and see appellee’s doctors, but being confused as to the ramifications of all of this, he refused to sign the forms and continued treatment under the care of his own physicians. According to Mr. Frances’s supervisors, he performed his regular job duties through January 1997 without any apparent impairment. However, one of his supervisors acknowledged that, while he did not witness the incident with the paper machine, he became aware of it within a week of its occurrence.
For reversal, Mr. Frances submits that the Commission erred in failing to find that he sustained a compensable injury. He notes that his account of the accident was corroborated by two co-employees, who noticed him limping and complaining of pain thereafter. Mr. Frances also notes that the initial reports of both Drs. Paulk and Dickins reflect a work-related injury that occurred in the manner described by his testimony. Although he was able to continue working, his job mostly included standing but no heavy lifting. A herniation was diagnosed two-and-one-half months after the accident, and when conservative treatment failed, surgery became necessary. As to causation of the back condition, Dr. Dick-ins stated in a report:
The statement that I can make about this is that the mechanism of injury that he describes could produce a lumbar disc injury. The history given that he initially sustained back pain and then four weeks later recurrent back and leg pain could be consistent with an injury to the disc initially, subsequently followed by the development of a herniation of that disc.
Based on the uncontradicted evidence, Mr. Frances argues that the only reasonable conclusion to be made is that his back condition and resulting treatment were caused by the accident at work.
We hold that there is no substantial basis to support the Commission’s decision to deny compensability. In its opinion, the Commission acknowledged that an accident occurred on September 23, 1996, but concluded that it only resulted in minor abrasions not worthy of compensation. We disagree. Four witnesses testified that, shortly after the incident, Mr. Frances was limping and complaining of back pain, and there was nothing in the record to indicate that Mr. Frances had prior back problems or that his current problems were caused by anything other than the accident at work. Although credibility determinations are left to the Commission, it is not free to arbitrarily disregard any witness’s testimony. See Wade v. Mr. C. Cavenaugh’s, 25 Ark. App. 237, 756 S.W.2d 923 (1988). Both doctors reported the accident consistent with that elicited by the testimony, and Dr. Dickins’s reports indicate gradual back problems resulting from the accident that eventually required surgery. While Mr. Frances continued to work after the accident, his job was light and it is apparent that he was trying to work through the pain.
In reaching its decision, the Commission relied in part on the fact that the December 6, 1996, report of Dr. Dickins references a work-related exacerbation on November 16, 1996, but that this incident was not accounted for by any of the other evidence presented. However, there was evidence that, at about that time in November, Mr. Frances missed two days of work due to back pain, and thus the reference in the medical report was not fatal to his claim.
The Commission also relied on the fact that, in January 1997, Mr. Frances refused to sign workers’ compensation forms or go to the insurance carrier’s doctor. However, in light of the testimony elicited about the January 1997 meeting, it is evident that he was understandably confused as to what his options were. Furthermore, his choice of physician has little to do with whether his back condition was caused by a work-related incident.
Finally, the Commission relied on Ark. Code Ann. § 11-9-102(16)(B) (Supp. 1997), which provides that medical opinions addressing compensability must be stated within a reasonable degree of medical certainty. Because Dr. Dickins’s opinion was that the accident as described by Mr. Frances could have caused the herniation and need for surgery, the Commission found that this requirement was not met. We disagree with this assessment.
As pointed out by the claimant in this case, a doctor will virtually never witness a compensable injury and must rely on the accounts given by their patients. This, however, does not necessarily preclude compensation. In Service Chevrolet v. Atwood, 61 Ark. App. 190, 966 S.W.2d 909 (1998), we held that this requirement was met when an ophthalmologist gave the opinion that the work-related incident was the kind of event capable of causing the injury suffered. The ophthalmologist stated, “[cjertainly, an acidic solution such as wheel cleaner can cause irregular corneal astigmatism like that present in [appellee].” Id. at 197, 966 S.W.2d at 913. The fact that a physician fails to use the magic words “reasonable medical certainty” does not, by itself, invalidate his medical opinion. See id. (citing Paulsen v. State, 541 N.W.2d 636 (Neb. 1996)). In the instant case, Dr. Dickens gave the opinion that the work-related accident was the kind of event that could cause the resulting back condition, and this was sufficient to satisfy the relevant statute.
For the foregoing reasons, we are compelled to reverse the Commission’s decision to deny compensability.
Reversed and remanded.
