Rehabilitation Practice and Science
Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, caused by the compression of the median nerve in the carpal tunnel over the wrist. The purpose of this study is to demonstrate how different wrist positions change median nerve image and their corresponding results of nerve conduction study (NCS). In this study, we investigated 40 normal wrists and 32 wrists with CTS. In both groups, subjects were randomly assigned to wear a splint, and the wrist was placed at 0, 15, 30 and 45 degrees of extension. Ultrasonography was performed before splinting, immediately after splinting and repeated again 2, …

The main purpose of the diagnostic ultrasound examination for carpal tunnel syndrome (CTS) is to compensate for the inadequacies of physical examinations and nerve conduction studies and thereby reduce the false negative rate of CTS diagnosis. The cross-sectional area of the median nerve, swelling ratio, flattening ratio, and palmar bowing of the flexor retinaculum have been reported as the diagnostic criteria for CTS in ultrasonographic examinations. In addition, Doppler ultrasound has been applied to measure the blood flow of the median nerve, and dynamic ultrasound combined with a cross-correlation algorithm has been developed to measure the gliding of the median …
