Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy in clinical practice, with a 0.1% life time risk in the general population. Conventional neurophysiological studies have been useful in the diagnosis of this condition, as have a number of more specialized procedures. Therefore, we evaluated the diagnostic sensitivities of several parameters in nerve conduction technique for CTS patients. We analyzed 100 patients (159 hands) who were diagnosed with CTS clinically and electrophysiolosically. Median motor and sensory nerve conduction velocities (MCV and SCV) with wrist, palm, and finger stimulation were performed in traditional methods. Sensitivities of each test were calculated and compared to normal control data. The sensitivities of existing nerve conduction method were noted in terminal latency on median nerve, 2nd finger-wrist segment, 3rd finger-wrist segment, palm-wrist segment and distoproximal ratio, as 72.96%, 92.45%, 94.34%, 94.97%, and 97.48%, respectively. In the early course of CTS, sensory nerve conductions in the median nerve are more valuable than motor nerve conduction. Sensory nerve conductions are usually affected before motor nerve conductions in CTS. In this study, we detected that slowing of median SCV was the most frequent in the distoproximal ratio.
