ABSTRACT
Objective To evaluate the function status of motor nerve in patients with carpal tunnel syndrome ( CTS) sensory neuropathy by single-fiber conduction studies ( SF-CS).Methods Forty patients with CTS were divided into two groups according to the nerve conduction abnormality of median nerve .The sensory conduction abnormalities ( SCA) group included 20 patients with abnormal sensory conduction , while the sensory motor conduction abnormalities ( SMCA) group included 20 patients with abnormal motor sensory conduction.The Keypoint.net electromyogram device was used to detect the wrist to the abductor pollicis brevis latency , using the saddle shaped stimulating electrodes for stimulating and the single fiber electromyography electrode for recording.The control group included 20 healthy people.Results The latency of single-fiber conduction of median nerve in SCA group , SMCA group and control group was (3.92 ±0.28) ms, (4.71 ±0.49) ms and (3.41 ±0.31) ms (F=63.829, P=0.000), respectively.The area under the receiver operating characteristic curve was 0.920 for the latency of single-fiber conduction of median nerve , and its specificity was 85%in cut off point.Conclusions There is clinical motor nerve damage in patients with CTS sensory neuropathy.The SF-CS may become an effective means for early evaluation of motor nerve function state.
