OBJECTIVE: To investigate the immediate and short-term effects of 3 commercial wrist orthoses on grip strength and function. METHODS:Thirty-six patients with definite rheumatoid arthritis participated in the randomized, controlled, cross-over design study of 3 commercial wrist extensor orthoses. Dominant-hand dynamometric grip strength was assessed at both initial and followup sessions while splinted and nonsplinted. Functional impact was assessed using a written questionnaire. RESULTS: All 3 commercial orthoses reduced grip strength when first donned. After a 1-week adjustment period, one orthosis, the Smith and Nephew Roylan D-Ring (Roylan), afforded splinted grip strength equal to that of the nonsplinted grip strength. The other 2 orthoses continued to reduce grip strength, and afforded splinted grip strength significantly below that of the Roylan. The Roylan was deemed comfortable by more subjects than the other orthoses. CONCLUSIONS: The belief that commercial orthotic use increases grip strength, either immediately or after 1 week, is not supported by this study's data. Different styles of commercial wrist orthoses appear to have differing influence on splinted grip strength.
