Abstract

The peroneal nerve SEPs over the CZ' of the scalp were studied in patients with peroneal nerve palsy. The initial positive peak latencies of P27 (to popliteal fossa stimulation), P30 (to fibular neck stimulation) and P37 (to dorsum of the foot stimulation) were measured. The latency difference P30-P27 was prolonged in all patients with the fibular head lesions. In patients with the superficial peroneal nerve lesions at the foreleg, P37-P27 was prolonged whereas P30-P27 was normal. Clinical application of peroneal nerve SEPs was useful in deciding the site of the lesion causing the peroneal nerve palsy.

摘要

对腓总神经麻痹患者进行了头皮 Cz’ 处的腓总神经体感诱发电位（SEP）研究。测量了 P27（腘窝刺激）、P30（腓骨小头刺激）和 P37（足背刺激）的起始正峰潜伏期。在所有腓骨小头病变患者中，潜伏期差值 P30 - P27 延长。在前臂浅表腓总神经病变患者中，P37 - P27 延长，而 P30 - P27 正常。腓总神经 SEP 的临床应用有助于确定导致腓总神经麻痹的病变部位。
