The effects of five minutes of wrist flexion on median motor and sensory evoked potential latencies in 87 individuals were studied. Nineteen subjects had carpal tunnel syndrome (CTS) as diagnosed by increased median nerve latencies across the wrist, and 68 had values in the normal range and were assigned to the control group. A slight prolongation of up to 0.5m sec of evoked potential latencies was observed in both groups after flexion, but the differences between the two groups were not significant to establish the value of adding wrist flexion to conventional screening methods.
研究了87名个体中五分钟腕关节屈曲对正中神经运动和感觉诱发电位潜伏期的影响。19名受试者经腕部正中神经潜伏期延长诊断为腕管综合征（CTS），68名受试者的值在正常范围内，被分配到对照组。两组在屈曲后均观察到诱发电位潜伏期有高达0.5毫秒的轻微延长，但两组之间的差异不显著，无法确定在传统筛查方法中增加腕关节屈曲的价值。
