Abstract

By using an isolated constant current stimulator producing true square-wave pulses, sensory strength-duration curves were obtained at various sites by percutaneous electrical stimulation. Strength-duration curves derived from normal groups were compared to those of patients with peripheral neuropathy. Stimulus strength at sensory threshold was shown to be a reproducible measure of sensory deficit, increasing parallel to the degree of axonal failure found by conventional methods. This may be useful as a complementary method in assessing peripheral neuropathy.

摘要

通过使用产生真正方波脉冲的隔离式恒流刺激器,经皮电刺激在不同部位获得了感觉强度-时间曲线。将正常组得出的强度-时间曲线与周围神经病变患者的曲线进行了比较。感觉阈值时的刺激强度被证明是感觉缺陷的一种可重复测量指标,其增加与通过传统方法发现的轴突损伤程度呈平行关系。这在评估周围神经病变时作为一种补充方法可能会有用。
