Ultrasound for carpal tunnel syndrome screening in manual laborers.

چکیده
INTRODUCTION Manual laborers are at increased risk for carpal tunnel syndrome (CTS), and a combination of history, physical examination, and nerve conduction studies is often used to screen for CTS in this population. Neuromuscular ultrasound may be a better screening tool, because it is painless. In this study we compare the accuracy of nerve conduction studies and ultrasound for CTS screening. METHODS Five hundred thirteen manual laborers were screened prospectively for CTS using nerve conduction studies and neuromuscular ultrasound, and the accuracy of the 2 techniques was compared using the Katz hand diagram as the diagnostic standard. RESULTS The ROC curves for the 2 techniques were not significantly different (P = 0.542), indicating that the approaches had similar diagnostic accuracy. CONCLUSIONS Neuromuscular ultrasound is a painless technique that has diagnostic accuracy similar to nerve conduction studies and can be used to screen large populations at risk for CTS.

متن کاملComparison of Ultrasound Findings of Carpal Tunnel Syndrome before and after Corticosteroid Injection
Background and Objective: Carpal Tunnel Syndrome is the most prevalent type of peripheral neuropathy due to neural entrapment. This syndrome is primarily diagnosed based on clinical symptoms, and it is subsequently confirmed by electro-diagnostic studies. Ultrasonography as a safe, available, and inexpensive method is also valuable in the follow-up of patients. This study aimed to evaluate the ...
