      However, if individuals have hand and/or wrist pain, strength measured via handgrip dynamometry will not give accurate assessments. A study reported that the prevalence of disabling wrist and hand pain was approximately 15% in occupational workers.

      Thus, it is necessary to consider muscle groups, other than the hand, for evaluating muscle strength in individuals who have hand and/or wrist pain. Although testing the knee extensors is one option, there are some older individuals with pain in their knees from conditions such as osteoarthritis
