Background We evaluated the responsiveness of patient-derived questionnaires and physical findings in evaluating recovery after treatment of ulnocarpal abutment syndrome. Methods Patients were assessed at their initial visit to our clinic and again 3 months after the treatment. At each visit, patients completed a Short Form-36, the Japanese Society for Surgery of the Hand version of Disability of the Arm, Shoulder, and Hand questionnaire (DASH-JSSH), and the Japanese version of patient-rated wrist evaluation (PRWE-J). Grip strength, range of motion, and visual analogue scale for wrist pain were also examined at each visit. Satisfaction with treatment was questioned after 3 months using a Likert scale. Standardized response means (SRM) and effect sizes were calculated to evaluate the responsiveness. Results The PRWE-J (SRM, 1.35) was the most responsive questionnaire, followed by the DASH-JSSH (SRM, 0.81) and the Short Form-36 (SRM, −0.38 to −1.19). Of the physical tests, grip strength (SRM, 0.81) was more responsive than range of motion (SRM, 0.01 to −0.29). The visual analogue pain scale (SRM, 1.56) was highly responsive. Changes in the PRWE score were correlated with the satisfaction rating for the treatment. Conclusions Responsive patient-derived scales can assist in the outcome evaluation of patients with ulnocarpal abutment syndrome. Ausführliche Beschreibung
