Brief summary

The aim of this study was to investigate the validity and reliability of the Upper Extremity Functional Index in patients with carpal tunnel syndrome. This cross-sectional study included 101 patients diagnosed with carpal tunnel syndrome at a university hospital. Patients were administered the Upper Extremity Functional Index, Michigan Hand Outcomes Questionnaire, and Boston Carpal Tunnel Questionnaire surveys. Test-retest reliability, internal consistency, and construct validity of the Upper Extremity Fuctional Index were evaluated.

Interventions

OTHERQuestionnaire

The Upper Extremity Functional Index (at the first session and after 2 weeks), the Michigan Hand Outcomes Questionnaire and the Boston Carpal Tunnel Questionnaire were administered to patients using a face-to-face assessment method.

Design outcomes

Primary

MeasureTime frameDescription
Upper Extremity Functional IndexThe questionnaire was administered at baseline (after diagnosis of carpal tunnel syndrome) and 15 days after the baseline assessment.It is a 20-item scale scored using a 4-point Likert scale (0 = Extremely difficult/I cannot do it, 4 = I do not experience any difficulty). The patient scores between 0 and 80, and it is recommended that the total score be used in studies. A high score indicates that the patient has good upper extremity function.
Michigan Hand Outcomes QuestionnaireThe questionnaire was administered at baseline (after diagnosis of carpal tunnel syndrome)This questionnaire evaluates the functionality of the hand and consists of 63 questions in total. Each question is scored between 1-5 and the score of each section varies between 0-100. High total score indicates high satisfaction.
Boston Carpal Tunnel QuestionnaireThe questionnaire was administered at baseline (after diagnosis of carpal tunnel syndrome)It has been developed to assess the severity of symptoms and functional status in patients with carpal tunnel syndrome. The symptom severity scale consists of 11 questions, while the functional status scale consists of 8 questions. Each question is scored between 1 and 5. A higher symptom severity or functional status score indicates worse symptoms or functional impairment.
