Cross-Cultural Adaptation, Validity, and Reliability of the Turkish Version of the Trapeziometacarpal Arthrosis Symptoms and Disability Questionnaire
Cross-Cultural Adaptation, Validity, and Reliability of the Turkish Version of the Trapeziometacarpal Arthrosis Symptoms and Disability Questionnaire
To our knowledge, a Turkish version of the TASD questionnaire, frequently used for assessing TMC arthrosis worldwide, does not currently exist. Therefore, proper translation and cross-cultural adaptation of the tool are necessary for non-English speaking patients. This study aimed to develop the Turkish version of the TASD questionnaire, and to demonstrate its reliability and validity for use in patients with TMC arthrosis.
The original TASD was translated into Turkish independently by a physiotherapist with expertise in hand research and proficiency in English, a healthcare professional, and English teacher with no healthcare background. Demographic data were collected, followed by administration of the TASD questionnaire, the Thumb Disability Examination (TDX) questionnaire, the Visual Analogue Scale (VAS) for pain assessment, and hand grip and pinch strength measurements using the Jamar® Hydraulic Hand Dynamometer and Jamar Hydraulic Pinch Gauge to assess thumb function and muscle strength. The questionnaires were administered twice, with a 7-day interval, during which no medical or rehabilitation intervention was provided that could alter the clinical condition of the patients.
