We studied nerve conduction in 24 patients with serratus anterior palsy of different etiology. On the unaffected control side, the latency of the evoked motor responses after stimulation of the long thoracic nerve in the supraclavicular fossa increased 0.2 msec per 10-mm increase in conduction distance, corresponding to a velocity of 67m-s. The method was valuable in determining whether the lesion was partial or complete and in revealing regeneration after wallerian degeneration.
我们研究了24例不同病因的前锯肌麻痹患者的神经传导情况。在未受影响的对照侧，刺激锁骨上窝的胸长神经后诱发运动反应的潜伏期，每传导距离增加10毫米，潜伏期增加0.2毫秒，相应的速度为67米/秒。该方法在确定病变是部分性还是完全性以及揭示沃勒变性后的再生情况方面很有价值。
