Is a joint

First carpometacarpal joint osteoarthritis is a common degenerative condition. The thumb has been reported to account for up to 50% of hand function and is functionally and biomechanically unique in the hand. To this end, it would seem appropriate that exercise programs for first carpometacarpal joint osteoarthritis would be specifically tailored to the thumb. However, this is not widely reflected in the literature. This review aimed to critically evaluate studies presenting primary evidence to determine whether a joint-specific exercise program is effective for patients with osteoarthritis in the first carpometacarpal joint. Six electronic databases were searched for papers presenting primary data relating to home exercise programs that were specific to osteoarthritis in the first carpometacarpal joint. Methodological quality of included papers was evaluated using the Structured Effectiveness for Evaluation of Studies tool and levels of evidence were established based on National Health and Medical Research Council (NHMRC) guidelines. Qualitative analysis of the combined body of literature was performed and a recommendation generated and then graded according to NHMRC guidelines. Searching identified three relevant papers. Overall, methodological quality was moderate, with limitations primarily related to lack of power. Findings from the body of literature demonstrated considerable variation, but evidence to support specific thumb strengthening exercises was found. This provided an NHMRC Grade D level of recommendation. It is recommended that future studies consider optimal frequency of strengthening exercises and the potential role of adductor pollicis release and passive carpometacarpal joint mobilization in home exercise programs for first carpometacarpal osteoarthritis
