Objectives: To determine the prevalence and factor related with median neuropathy at wrist (MNW) in systemic sclerosis patients. Study Design: Cross-sectional study. Setting: Srinagarind Hospital, Khon Kaen, Thailand. Participants: Systemic sclerosis patients who attended the Scleroderma Clinic, Srinagarind Hospital. Materials and Methods: Seventyfive systemic sclerosis patients were prospectively evaluated by questionnaire, physical examination, and electrodiagnostic study. The questionnaire consisted of the symptoms, duration, and type of systemic sclerosis. The physical examination revealed skin score of systemic sclerosis, pinprick sensation of median nerve distribution of both hands, and weakness of both abductor pollicis brevis muscles. The provocative test which were Tinel′s sign and Phalen′s maneuver were also examined. Moreover, electrodiagnostic study of the bilateral median and ulnar nerves was conducted. Results: The prevalence of MNW in systemic sclerosis patients was 44% - percentage of mild, moderate, and severe were 28%, 9.3%, and 6.7%, respectively. The prevalence of asymptomatic MNW was 88%. There were no association between the presence of MNW and related factors of systemic sclerosis. Conclusions: MNW is one of the most common entrapment neuropathies in systemic sclerosis patients. Systemic sclerosis patients should be screened for early signs of MNW
