Q-DASH questionnaire is applied to evaluate upper extremity-related functionality and symptoms. Each item provides 5 response options and the overall score is calculated from the item scores. 0, no loss of function; 100 is interpreted as the most severe loss of function.

The Boston Questionnaire (BA) is specific to Carpal Tunnel Syndrome (CTS) and consists of two different scales that evaluate symptom severity and functional capacity.The scoring of each item varies between 1 and 5. The average score is obtained by dividing the total score by the number of items and ranges from 1 to 5. A high score indicates low functional capacity. Mean scores are calculated separately for symptom severity and functional capacity. The symptom score consists of 11 items and the function score consists of 8 items.

Grip strength was measured with the Jamar hand dynamometer, which is recommended by the American Association of Hand Therapists (AETD) and whose validity and reliability have been confirmed in many studies.According to the measurement procedure, three repeated measurements were made for hand grip strength and the results were recorded in kilograms.

The water flooding method, which is considered the gold standard in the measurement of extremity volume and is preferred in the evaluation of edematous hand or foot volume, was used in this study.With this measurement method, the amount of overflowing water volume between the affected and unaffected extremities was compared and the amount of edema was determined.
