The Industrial Accident Commission determined that respondent Joe Serafín was entitled to a 3214 per cent permanent disability rating by reason of the condition of his right hand which was the result of an industrial injury. The sole contention is that the evidence is insufficient to support that rating.
The employee, a carpenter, was examined by Dr. Duggan, acting assistant medical director of the commission, on January 6,1947, and an informal rating of 8% per cent permanent disability was made. The employee filed an application for adjustment of claim in March, 1947. In that proceeding the report of the employee’s physician, Dr. Silberman, showed a loss of grasping strength in his right hand of 25/80, and concluded with the statement that: “His condition is stationary and permanent. Residual factors on which it is believed a permanent disability rating should be based are: pain and swelling, increased on use, restricted motion, impaired grip and tenderness on palpation.” In April, Dr. Harrison, assistant medical director of the commission, examined the employee and found several factors of disability. His report stated: “As requested, I have examined this applicant this morning. with reference to his right major hand.
“He states that at irregular intervals, particularly when his hand is tired and warm, he experiences a sudden sharp pain extending from the metacarpophalangeal joints of the middle and ring fingers to the elbow. When this occurs he frequently drops any object he may be holding. He states that for perhaps one hour he experiences ‘cramps’ in the hand. Cold weather does not affect his condition, but in warm weather it is worse.
“There is some thickening over the second metacarpophalangeal joint and pressure over the metacarpophalangeal joint of the ring finger causes some pain. The tip of the thumb fails the base of the middle finger by 1%",- on the opposite side the tip of the thumb fails the base of the middle finger by In abduction the tip of . the thumb fails the shaft *91 of the second metacarpal by 2%"; on the opposite side by 3".
‘ ‘ In making a fist the tip of the index finger fails the palm by 2%", the tip of the middle finger by 1%", the tip of the ring finger approximates the thenar eminence 11/6" proximal to the palmar crease, the tip of the little finger approximates the hypothenar eminence 1" proximal to the palmar crease. There is 20° lack of extension in the proximal interphalangeal joint of the ring finger. There is 22° lack of extension in the distal interphalangeal joint.” He found a loss of grasping power of 15/165. He also said he believed the employee did not exert his best efforts in grasping. The employee testified that he could not use his right hand and was not able to do any work; that there was pain in his hand when he attempted to pick up articles; that his right hand is not as strong as his left and he cannot “squeeze” much with it; and that he has no grip in his right hand. He stated that in the examinations by all the doctors he put forth his best effort in the gripping tests.
The doctors for the insurance carrier gave varied figures on the gripping potentiality of the right hand as compared to the left, as follows: Dr. McCarthy, 85/100, 75/95, 75/115, 75/120, 80/125, 80/115, 60/90; Dr. Cline 70/0, 80/0; Dr. Boynes, 85/100; 75/115; Dr. Sale, 50/110. They testified that the employee was not making a proper effort with his right hand when being tested on the dynamometer, the device used for testing grasping strength.
It will be seen from the foregoing that the rating given (32% per cent of which 1 per cent was for pain, leaving 31% per cent representing a difference between the right and left hand of 30/165) was within the range of the testimony given by the various witnesses which ran the gamut from practically no loss of grasping strength to 100 per cent loss. No witness testified to the exact figure (30/165), and, therefore, petitioner claims that the award cannot stand because the referee arbitrarily chose a figure not supported by any evidence, and reference is made to the referee’s report where he said: “Mr. Jakobson seems to be very earnest in his attitude that the ease should not rate over 8%%, as was given on the informal rating. Dr. Harrison on April 1, 1947, found the right grip, under three tests, 10-15-10. He thought the applicant was exaggerating the loss of grasping power, but naturally he could not say how much, so I simply decided that the applicant was probably doing half as well as he could, and therefore fixed the loss of grasp at 30/165. Mr. Jakobson complained *92 that there was no evidence any place, at any examination, of it being over 30/165. I told him the theory under which I had made the rating, and that of course I could have taken it at 15/165, and might get into trouble in an endeavor to do what seemed to be the equitable rather than the strictly legal thing.
“I suggested that the parties add the 8%% and 32%%, which of course makes 41%, divide it by 2, which would give a 20%% rating, and if they wanted to discuss settlement on that basis, perhaps because of the uncertainties of the case, and the difficulty of being mathematical, it might be the best disposition of the case. I told the parties, however, that I had just as much right, perhaps more authority, to determine the doctor’s feelings that the man was not honestly doing the best he could to grasp the dynamometer or hand, were not as persuasive to me as the man’s sworn testimony based on a general estimation of his capacity for veracity that he had done the best he could, and that there was some difficulty in the hand, not immediately perceivable by these examining doctors, responsible for the loss of grasping power; that I would hesitate to believe that a carpenter of this man’s age and general appearance, whose reputation for veracity was unchallenged, and who could make the money he could now make as a carpenter, would claim the disability he claims unless he either had it or believed he had it, which amounted to the same thing as not having the grasping power. That 32%% [32%%] was not a tremendous rating for any carpenter who had lost a great amount of the usefulness of his right hand.”
In the first place it is a panel of the commission and not the referee who makes the findings and award. (See, Lab. Code, § 5800;
Lumbermen’s Mut. Cas. Co.
v.
Industrial Acc. Com.,
A review of the record discloses that there is ample evidence that the employee lost all grasping power (the employee’s testimony) as well as evidence that he lost practically none, and evidence by an expert of a 15/165 loss which is greater than the finding of 30/165. There is evidence of other factors such as pain and inability to flex the fingers. Plainly this evidence is sufficient to support the award.
It is the province of the commission to resolve conflicts in the evidence and that includes the factors of observation of the employee’s disability, the extent, if any, to which the employee was not exerting his full effort on the dynamo-meter when tested, and the effect of that factor on the various views as to the relative grasping power of the injured and normal hand. Arriving at a decision on the exact degree of disability is a difficult task under the most favorable circumstances. It necessarily involves some measure of conjecture and compromise by the finder of fact as certainly would occur in the mental processes of a so-called expert witness. When the commission is confronted with widely divergent views as to the extent of the loss of function of the body, further complicated by the possibility of lack of cooperation or faking in various degrees by the injured

person, it may make a determination within the range of the evidence as to the degree of disability. Applicable here is the rule followed in other cases where the trier of fact does not adopt exactly the view of any expert witness as to value. The trier of fact may accept the evidence of any one expert or choose a figure between them based on all of the evidence.

v.
Industrial Acc. Com.,
“In discussing the subject of expert testimony in the Simpson case, the court cited several eases in which damages were claimed because of the alleged malpractice of a physician, and then said: ‘The rule to be drawn from these decisions, as we understand them, appears to be that whenever the subject under consideration is one within the knowledge of experts only, and is not within the common knowledge of laymen, the expert evidence is conclusive upon the question in issue. It follows that in such cases, neither the court nor the jury can disregard such evidence of experts, but, on the other hand, they are bound by such evidence, even if it is contradicted by nonexpert witnesses.’ (P. 243.) The general rule is that the law does not require expert testimony to be offered wherever relevant. Malpractice cases are an exception. In such a case the plaintiff must prove by members of the defendant’s profession the standard of care or skill ordinarily used in the practice of that profession at a particular place.

Industrial Acc. Com.,
In any event it should be obvious that the loss of gripping strength of the hand is not a subjective condition that requires scientific proof. Certainly the injured person may testify to the extent of his disability and the commission is fully qualified to determine the question from all of the evidence. We are not dealing with the question of the subjective scientific cause of an injury. It is clear that the injury caused the disability. The issue is only the extent of that disability. Various analogous situations have been presented and it has been held that testimony by a lay witness is proper to show the immediate consequences of an injury received by him
