Abstract
Background/aim This study aimed to translate and validate the Turkish version of the Hand20 questionnaire.Materials and methods Patients who had upper extremity involvement and stable symptoms for the previous 4 weeks in their upper extremities were included in the study. Patients who were illiterate or used a splint during the day were excluded from the study. Participants completed the Turkish version of the Disabilities of the Arm, Shoulder, and Hand (DASH-T) questionnaire once and the final version of the Hand20 questionnaire twice in a 7-day interval. Internal consistency and reliability of the questionnaire was assessed. Moreover, correlations between Hand20 and DASH-T scores were analyzed using Spearman’s correlation coefficient.Results A total of 104 patients participated in the study. The Turkish version of the Hand20 met the set criteria of reliability and validity. Internal consistency (Cronbach’s alpha = 0.93) and test-retest reliability were excellent (r = 0.82). Hand20 showed a positive and statistically significant correlation with DASH-T (r = 0.76, P < 0.001).Conclusion The results showed that the Turkish version of the Hand20 had excellent test-retest reliability and validity. As a result of this study, it was determined that Hand20 was a valid and reliable instrument to measure the upper extremity disabilities of Turkish-speaking patients.
Highlights
Outcome measurements, which have great importance in evaluating the results of treatment, can be divided into 2 groups; clinician-focused tests and patientbased outcome measures

Summary
Outcome measurements, which have great importance in evaluating the results of treatment, can be divided into 2 groups; clinician-focused tests and patientbased outcome measures. Clinician-focused tests have been used to assess physical functions, such as range of motion, muscle strength, and sensory functions, in upper extremity disorders. In these tests, objective results have been reflected, but subjective results, such as a patient’s perceptions, pain, or daily living activities, have not been [1,2]. Patient-based outcome measurements were developed to evaluate the level of a patient’s disability and allow for comprehensive evaluation. Numerous patient-based outcome measurements for the upper extremities have been developed. Deciding the most compatible instrument to assess the affected upper extremity is difficult [5]
