delivered the Opinion of the Court.
The claimant and appellant, Randy L. McIntyre, appeals the judgment of the Montana Workers’ Compensation Court that his disability resulting from thoracic outlet syndrome had not been proven by a preponderance of the evidence to result from his 1987 injury. We affirm.
The following issues are on appeal:
1. Did the Workers’ Compensation Court err in concluding that the claimant’s thoracic outlet syndrome did not result from his 1987 injury?
2. Is the claimant entitled to temporary total disability benefits as a result of his 1987 injury?
3. Is the claimant entitled to permanent partial disability benefits as a result of his 1987 injury?
4. Is the claimant entitled to costs, attorney’s fees, and a penalty award?
McIntyre was injured in an industrial accident in the course of his employment with Glen Lake Irrigation District on May 9,1987, near Eureka, Montana. He was attempting to change a flat tire on a heavy equipment trailer when the jack he was using began to tip. While *65reaching under the trailer to try and release the jack, the jack slipped and the trailer came down; the trailer tire struck McIntyre’s chest and pinned him to the ground.
McIntyre’s wife discovered him under the trailer and, after jacking up the trailer to remove the claimant from under the tire, sought help in taking him to Dr. Andrew Ivy, a physician in Eureka. Dr. Ivy diagnosed the claimant as having suffered a fractured left clavicle and chest contusions. He prescribed medication for the pain and put McIntyre’s arm in a sling. Two days later he set the fractured clavicle in a cast and x-rayed it. He saw the claimant several more times to check the claimant’s progress, the last time being June 15; on that occasion, he advised the claimant to return in one month for another x-ray. Dr. Ivy’s records indicate that McIntyre did not return one month later. Dr. Ivy never did remove the claimant’s cast and it was not until McIntyre suffered a second work-related injury in 1988 that Dr. Ivy saw him again.
As a result of the 1987 injury, McIntyre missed approximately three months of work. He and his wife agreed with the employer that McIntyre’s wife would perform his regular job duties during this time, in return for which the employer would pay McIntyre his usual wage.
On May 15, 1988, McIntyre was injured in a second industrial accident arising out of his employment with Glen Lake Irrigation District. While standing in waist-deep water attempting to clear a beaver dam from a ditch, he pulled a small log out of the ditch and turned to throw it over his right shoulder when he felt a “pop” in his back. He immediately felt a pain in his neck and right shoulder area, and noticed numbness and tingling in his right arm. The claimant finished the work day and returned to work the next day.
The soreness continued, however, so he reported the injury to his employer and went to see Dr. Clay McDonald, a chiropractor in Eureka. Dr. McDonald referred McIntyre to Dr. Ivy. Upon examining the claimant on May 23, 1988, Dr. Ivy found him to have pain in the right shoulder area when he turned his head to the right. Dr. Ivy also found that the right rotation of McIntyre head caused a sensation going down McIntyre’s right arm into the fingers. Dr. Ivy made the following diagnosis:
“I thought he had done something in his neck by that sudden motion, that pinched one of his cervical nerves, and therefore I gave him a collar to wear and I gave him some cortisone, a good dose to take. And at that date he brought Doctor McDonald’s X-rays which showed a slight degeneration of the disc between cervical 5 and 6 with *66some spurring, and I assumed that was probably the source of his problem.”
Dr. Ivy saw McIntyre again on May 27, 1988. The claimant returned to work on June 1, 1988. He ceased working June 12,1988, because of pains in his neck, right shoulder and right arm, including tingling and numbness.
Dr. McDonald, the chiropractor in Eureka, referred McIntyre to Dr. Stephen Martini in Kalispell. Dr. Martini has no board certification but limits his practice to “spine rehabilitation.” During his first visit with the claimant on July 12, 1988, Dr. Martini obtained a history from McIntyre which included a description of the 1988 injury, but not the 1987 injury; that history reflected that McIntyre noticed pain in the low thoracic area toward the end of the day on which the May, 1988 injury occurred. Dr. Martini assessed the claimant’s problems as right thoracic outlet syndrome (TOS), cervical spondylosis and a possible bulging cervical disc. On August 17, 1988, his assessment continued to include cervical spondylosis and a bulging cervical disc, but made no mention of TOS. Dr. Martini was not advised of the 1987 injury until April 20,1989. Occupational therapist Tim Tracy also obtained a history from McIntyre in July, 1988; again McIntyre made no mention of the 1987 injury when indicating problems with his right arm and shoulder.
For reasons not entirely clear on the record, McIntyre went to see Dr. Richard Nelson, a neurologist in Billings, Montana, in November, 1988. Dr. Nelson obtained a history of both the 1987 and 1988 injuries and diagnosed cervical, lumbosacral sprain syndrome, a bulging disc and right TOS. Later, in a June 1, 1989 letter to the claimant’s attorney, Dr. Nelson stated:
“Since the thoracic outlet syndrome is placed in that same exact anterior cervical spine taht [sic] the fracture took place, it is more likely than not that this was, indeed, the origin of his thoracic outlet syndrome. With regard to his neck syndrome he has osteoarthritic spurring and bulged disc which is causing some thecal indentation in the neck and no one would be able to tell when that occurred, in either the first or the second accident.”
In November, 1989, Dr. Martini stated by letter to the claimant’s attorney that, due to the trauma involved in the first accident, it was his opinion that the TOS was “most consistent with the mechanism of injury surrounding the first incident.” He further recommended that the claimant enroll in the Spinal Rehabilitation Program.
McIntyre entered the Kalispell Regional Hospital Spinal *67Rehabilitation Program on January 15, 1990. In the admission history, Dr. Martini recorded that McIntyre had suffered a fractured right clavicle in 1987 and had, at the time of that occurrence, experienced “right upper extremity numbness and discomfort.”
Trial was held in the Workers’ Compensation Court on May 23, 1990. The medical evidence and testimony of Dr. Ivy and Dr. Martini were entered by depositions. The Workers’ Compensation Court entered its Findings of Fact and Conclusions of Law and Judgment on October 18, 1990, ruling that the claimant had failed to causally relate the TOS to his 1987 injury by a preponderance of the evidence. The Workers’ Compensation Court recognized that it was without jurisdiction to consider the 1988 injury at that time; therefore, it could not establish any disability entitlements.
The first issue is whether the Workers’ Compensation Court erred in concluding that the claimant’s TOS did not result from his 1987 injury. We note that the question before this Court is not whether a 1987 injury occurred; nor is it whether the claimant’s TOS was proved by a preponderance of the medical evidence. The question the claimant presented to the Workers’ Compensation Court is whether the 1987 injury caused his TOS.
We begin our analysis by considering the question of what standard of review to apply. The claimant argues that this Court should review the Workers’ Compensation Corut’s decision based upon a preponderance of the evidence rather than utilizing the usual substantial credible evidence test. This argument is based on the fact that the medical testimony has been entered into evidence by deposition and we, therefore, sit in as good a position as the Workers’ Compensation Court to judge the weight to be given to such record testimony. The claimant is correct as to the medical evidence on a stand alone basis.
As we have often and consistently stated, the standard of review for decisions of the Workers’ Compensation Court is whether substantial credible evidence exists to support the court’s decision. Roadarmel v. Acme Concrete Co. (1989), 237 Mont. 163, 772 P.2d 1259; O’Brien v. Central Feeds (1990), 241 Mont. 267, 786 P.2d 1169. Where medical testimony is offered by deposition, however, we have held that this Court sits in as good a position as the Workers’ Compensation Court to judge the weight to be given that testimony. Roadarmel 237 Mont. at 168, 772 P.2d at 1262. Thus, the claimant is correct that this Court may review and weigh the medical deposition testimony.
This independent review standard does not apply to our review of *68the entirety of the case before the Workers’ Compensation Court and that court’s overall decision, however. As we stated in Sciuchetti v. Hurt Construction:
“Claimant points out that because all of the medical testimony in this case was by deposition, this Court is in as good a position as the Workers’ Compensation Court to judge the weight to be given that testimony. (Citation omitted.) While that standard of review is correct, this Court will nevertheless uphold the lower court if there is substantial credible evidence to support its conclusion.”
Sciuchetti v. Hurt Construction (1989), 238 Mont. 170, 174, 777 P.2d 308, 311. Thus, this Court’s review of the medical depositions must be overlaid onto an encompassing review of the Workers’ Compensation Court’s decision under the substantial credible evidence standard. This result is both obvious and necessary when we consider that other important evidence — in this case, the testimony of both the claimant and his spouse — was before the Workers’ Compensation Court as oral testimony; this is particularly important where, as here, the medical histories on which the doctors so heavily relied also were provided by the claimant himself. The Workers’ Compensation Court remains in the best position to determine the credibility and weight to be given to live testimony.
In Snyder v. San Francisco Feed and Grain (1987), 230 Mont. 16, 748 P.2d 924, we reviewed the evidence introduced by medical deposition and found “the medical evidence, together with other evidence” was “in stark contrast with” the conclusion of the Workers’ Compensation Court. (Emphasis added.) Snyder at 25, 748 P.2d at 929. Lest we create another standard of review to muddy the waters, we note that “stark contrast” in Snyder was merely a creative way of stating that there was not substantial evidence to support the Workers’ Compensation Court’s decision in that case. It is not this Court’s function to determine whether there is sufficient evidence to support contrary findings. O’Brien at 272, 786 P.2d at 1172.
Thus, in reviewing the decision in the case at bar, we will not substitute our judgment for the Workers’ Compensation Court if there is substantial credible evidence to support its conclusion that the claimant did not prove the TOS to be causally related to the 1987 injury. We find such evidence in the record.
The evidence shows that Dr. Ivy was McIntyre’s only treating physician for the 1987 injury. Dr. Ivy testified that McIntyre never complained of TOS symptoms (pain and numbness in the right shoulder, arm and hand) prior to the 1988 injury. Dr. Ivy was also the *69first medical doctor to examine him after his 1988 injury. Finally, Dr. Ivy stated clearly that he could not relate the TOS to the 1987 injury since the TOS was on the right side and the fractured clavicle was on the left.
Dr. Nelson’s opinion, set forth in his June 1, 1989 letter to claimant’s attorney, was based on an examination of claimant conducted one and a half years after the 1987 injury and a medical history provided entirely by McIntyre. Furthermore, Dr. Nelson expressed the belief that the 1987 injury was “more likely than not” the origin of his TOS because the TOS “is placed in that same exact anterior cervical spine taht [sic) the fracture took place.” McIntyre suffers from right TOS, which is not placed in the “same exact” area as the left clavicle which was fractured in the 1987 accident.
The evidence also shows that Dr. Martini was not aware of the 1987 accident until April, 1989, almost two years after it had occurred and approximately nine months after he diagnosed the right TOS in July, 1988. Dr. Martini admitted that in assigning causation of injuries to the two separate accidents he relied almost entirely on what McIntyre reported to him. And although Dr. Martini correctly indicated in his office notes on April 20, 1989, that McIntyre had fractured his left clavicle in 1987, he incorrectly reported that McIntyre was suffering from right TOS as a result of a fractured right clavicle when admitting him for inpatient spine rehabilitation in January, 1990.
The fact that Dr. Martini relied so heavily on McIntyre’s narrations and recountings of the 1987 and 1988 injuries makes it clear why the claimant’s oral testimony, although not medical evidence, was an important factor in the Workers’ Compensation Court’s decision and must result in this Court basing its overall review on the substantial credible evidence test. McIntyre’s credibility and the weight to be given to his testimony are judgments to be made by the Workers’ Compensation Court; that credibility, as determined by the Workers’ Compensation Court, appropriately may carry over into the credibility of the doctors’ diagnoses based on the claimant’s statements.
The claimant claims to have experienced numbness and pain in the right shoulder and arm prior to the 1988 injury, but admits that he did not report any of these symptoms to any physician until after the 1988 accident. Indeed, the claimant did not advise either Dr. Martini or Mr. Tracy of the 1987 injury when he saw them regarding the 1988 injury and did not suggest to them at that time that the right shoulder and arm symptoms predated the 1988 injury. In addition, *70McIntyre claims the 1988 injury did not immediately bother him, while Dr. Ivy testified that McIntyre reported immediate numbness in his right shoulder and arm after the 1988 injury.
The weight to be given to the totality of the testimony and evidence is a determination to be made by the Workers’ Compensation Court, not this Court. As that court concluded:
“[Claimant's medical history from 1987 to May, 1988 does not include any ongoing problems with his right arm. Indeed, it appears that most, if not all of claimant’s complaints regarding the numbness and tingling in the arm originate after the 1988 injury as evidenced in nearly all of the medical records. ... given the history and complaints recorded by the physicians before any dispute arose in this case, the medical opinion of causation relating thoracic outlet to the fractured clavicle when anatomically the former is on the right and the latter the left, and the fact that claimant did not complain of or seek medical treatment for the thoracic outlet symptoms until after the 1988 injury, we are convinced that he has failed to causally relate the thoracic outlet to the 1987 event. (Emphasis added.)”
The claimant argues that Dr. Ivy’s testimony lacked the proper foundation necessary for admissible evidence regarding expert opinion. He asserts that the Workers’ Compensation Court gave too much weight to Dr. Ivy’s testimony regarding TOS causation.
The determination of admissibility of expert testimony rests solely within the discretion of the trial court. Krohmer v. Dahl (1965), 145 Mont. 491, 402 P.2d 979. Furthermore, it is for the trier of fact to give whatever weight it sees fit to expert testimony. Biegalke v. Biegalke (1977), 172 Mont. 311, 564 P.2d 987. The Workers’ Compensation Court did not abuse its discretion in considering Dr. Ivy’s testimony.
From the foregoing review of the record, we find that substantial credible evidence exists to support the decision of the Workers’ Compensation Court.
The second issue is whether McIntyre is entitled to temporary total disability benefits for the three-month period following his 1987 injury.
The Workers’ Compensation Court concluded that the claimant was not entitled to temporary total disability benefits. We agree.
Temporary total disability is defined in § 39-71-116(20), MCA, as a condition that “results in total loss of wages.” As a result of an arrangement between himself, his wife and his employer, the claimant continued to receive his regular wage during that three-month period. The claimant would have us believe that since it was *71his wife who performed the work, it was his wife who was paid and not him. The record does not support this contention. While both the claimant and this Court might question the wisdom of the arrangement entered into by him, the wages were nonetheless paid to McIntyre.
It is unnecessary to address the remaining two issues the claimant raises since he has failed to relate his current disability to the 1987 injury and since there has been no award of benefits as a result of his appeal.
Affirmed.
