Which outcome measure is the best? Evaluating responsiveness of the Disabilities of the Arm, Shoulder, and Hand Questionnaire, the Michigan Hand Questionnaire and the Patient-Specific Functional Scale following hand and wrist surgery.

The purpose of this study was to determine and compare the responsiveness of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, the Michigan Hand Questionnaire (MHQ), and the Patient-Specific Functional Scale (PSFS) in patients with carpal tunnel syndrome, wrist pain, finger contracture, or tumor. Eighty-one subjects prospectively completed each questionnaire shortly before and 3 and 6 months after surgery. Data were analyzed using one-way analysis of variance and Newman-Keuls multiple comparison tests. Responsiveness to clinical change was calculated using standardized response means. The DASH was responsive for those with carpal tunnel syndrome (0.77), wrist pain (0.61), and tumor (0.55); the MHQ was responsive for those with carpal tunnel syndrome (1.04), wrist pain (0.87), and finger contracture (0.62); and the PSFS was responsive for those with carpal tunnel syndrome (0.65) and finger contracture (0.64). The interval during which the highest responsiveness occurred for the carpal tunnel, wrist pain, and finger contracture groups was the preoperative to 6-month period. The tumor group experienced the highest responsiveness during the preoperative to 3-month period. Our results indicate that one or more of the instruments evaluated are suitable for outcomes research related to surgery to treat carpal tunnel syndrome, wrist pain, finger contracture, and tumor.
