The symptoms are usually sensed in the first three radial fingers and the lateral side of the ring finger because these areas are innervated by the median nerve. Objective: To assess hand function among patient with Carpal Tunnel Syndrome (CTS). Methods: This was a descriptive study in which 41 subjects (27 females and 14 males) were included from Ghurki trust teaching hospital, Lahore and Shalamar hospital, Lahore (from August 2018 to October 2018) according to inclusion criteria. Samples were collected according to WHO (World Health Organization) calculator. Hand function was measured with Boston Carpal Tunnel Questionnaire (BCTQ). Results: Majority of the patients with CTS fell into mild functional severity and mild symptom severity. The mean score for functional severity was 2.34 and for symptom severity it was 2.97. Conclusion: Activities of daily living such as grasping, writing, gripping and carrying objects were affected by the symptoms of pain, numbness, tingling and weakness in the patients suffering from CTS.展开更多
