title: Comparative responsiveness of Japanese versions of the DASH and SF-36 questionnaires and physical measurement to clinical changes after carpal tunnel release.
abstract: The purpose of the present study was to test the responsiveness of the Japanese Society for Surgery of the Hand version of the Disability of the Arm, Shoulder and Hand questionnaire (DASH-JSSH) by evaluating effect size (ES) and standardised response mean (SRM) in patients undergoing carpal tunnel release. Subjects comprised 25 patients with carpal tunnel syndrome. All subjects completed the DASH-JSSH, medical outcomes 36-item short-form health survey (SF-36) and visual analogue scale (VAS) for pain and underwent objective assessment of grip strength, pinch strength and static two-point discrimination before and three months after surgery. DASH-JSSH displayed the highest sensitivity to changes at three months, followed by VAS. All subscales of SF-36 were much less sensitive and both grip and pinch strength were unchanged over the three-month period. DASH-JSSH demonstrated more responsiveness to changes after carpal tunnel release than SF-36, VAS and physical measurements, and displayed correlations with subscales of SF-36.
