This study was done to evaluate the effect of rising temperature on nerve conduction parameters in 22 patients with carpal tunnel syndrome (CTS). We wanted to find out whether diseased nerves responded to temperature rise in a different manner from normal controls. For this purpose a group of 20 healthy individuals were also tested. With rising temperature motor nerve conduction velocities increased, whereas latencies, amplitudes and duration of the compound muscle action potential decreased in both groups. These changes were not statistically significant between the two groups. Sensory nerve conduction parameters yielded basically similar findings except for a significantly smaller reduction in amplitude of the compound nerve action potential (CNAP) in the CTS group (p < 0.005). We conclude that there is a different response in the sensory CNAP amplitude between normal and CTS groups, but the same nerve conduction correction formulae for temperature can be used in CTS patients as in normal individuals in the event of low skin temperature.
本研究旨在评估温度升高对22例腕管综合征（CTS）患者神经传导参数的影响。我们想弄清楚患病神经对温度升高的反应是否与正常对照组不同。为此，还对一组20名健康个体进行了测试。随着温度升高，两组的运动神经传导速度均增加，而复合肌肉动作电位的潜伏期、波幅和时限均降低。两组之间这些变化无统计学意义。感觉神经传导参数得出基本相似的结果，只是CTS组复合神经动作电位（CNAP）波幅的降低明显较小（p < 0.005）。我们得出结论，正常组和CTS组在感觉CNAP波幅方面存在不同反应，但在皮肤温度较低的情况下，CTS患者可使用与正常个体相同的温度神经传导校正公式。
