Assessment of Validity, Reliability, Responsiveness and Bias of Three Commonly Used Patient-Reported Outcome Measures in Carpal Tunnel Syndrome

Abstract

1. This study ha show n that the BQ, DASH and M(2)DASH questionnaires are valid and reliable outcome measures for CTS. 2. In terms of responsiveness, the DASH and M(2)DASH questionnaires are not as responsive as the BQ scores over the initial post-operative recovery period. 3. We would therefore recommend that the Boston Questionnaire be used to assess early post-operative patient related outcome measures for Carpal Tunnel Syndrome.
