腕道症候群患者正中神經及尺神經傳導受溫度影響之比較

Abstract

”The purpose of this study is to compare the different nerve conduction responses of median nerve (MN) and Ulanr nerve (UN) in patients with carpal tunnel syndrome (CTS) after changing the temperature of hands.Thirty hands of CTS group were evaluated and compared to those of normal subjects by exposing the hands for 20 minutes to (1) room temperature (25℃). (2) cold water (15℃), and (3) hot packing (70℃). Then we measured the temperature, motor and sensory nerve conduction latencies of those hands immediately after each exposure. When comparing with room temperature, the distal latencies (DL) of both MN and UN increased after cold exposure for hands of each group: The percentage of delay of motor DL is 36-5% in CTS group and 26.5% in normals. The percentage of motor DL difference between MN and UN is 70.4% in CTS group while in normal hands it's 24.2%. The sensory latency discrepancy between MN and UN also increased more in CTS group. On the contrary, the conduction latency discrepancies did not change significantly between conditions of hot and room temperature. In a word, cold condition prolonged the distal latency more in CTS group than in normals and more for MN than that for UN of the same hand in CTS group.Therefore we can make a challenge lest for those patients with borderlincd CTS by means of cold exposure in the EMG laboratory.
