Questionnaires, which are used to express the perception of difficulty and hand functionality during daily living activities of individuals with carpal tunnel syndrome, and most importantly, which are easy to administer, should be preferred in order to plan a patient-specific treatment program with these results. Self-administered questionnaires showing the physical dimension of recovery are effective and sensitive to change.~Hand20 is a short, easy-to-understand and visual questionnaire used to evaluate disorders caused by upper extremity pathologies, developed by Suzuki et al. in 2010 and proven to be valid in upper extremity diseases by Töre et al. In this questionnaire consisting of 20 questions, the answer to each question is graded between 0 and 10 (0: No restrictions, 10: Impossible). The best score is 0, the worst score is 100.~Boston carpal tunnel syndrome questionnaire (BKTSA) will be used to evaluate the functionality level and symptom severity of the patients. In this questionnaire, which consists of 2 parts: symptom severity and functional capacity, a separate average score will be calculated for each part by dividing the total score obtained by the number of questions. An increased score indicates decreased functional capacity and increased symptom severity.
The validity of the questionnaire will be investigated by administering the El 20 questionnaire and the Boston Carpal Tunnel Syndrome Questionnaire to patients with carpal tunnel syndrome, one week apart.
