The diagnostic yield of different electrophysiological criteria was examined to establish whether a peroneal palsy was due to compression of the nerve in the region of the capitulum fibulae. Slowing of sensory conduction along the segment of the nerve across the capitulum fibulae localized the lesion in 64% of 47 consecutive patients with a history indicating or suggesting compression of the nerve in the vicinity of the capitulum fibulae and there were no false positive findings in 18 patients whose peroneal palsy was not due to compression at the capitulum fibulae. In 20% of the patients with slowing along the segment across the capitulum, conduction velocity was normal when measured from the superior retinaculum to the popliteal fossa. Slowing along motor fibres (m. extensor digitorum brevis) localized the site of the lesion in one-third of the patients. Differences in amplitude and in split-up of the sensory responses recorded in the popliteal fossa as compared with those recorded distal to the capitulum fibulae were of limited diagnostic value because of many false positive findings among patients whose peroneal palsy was not due to compression of the nerve at the capitulum fibulae.
对不同电生理标准的诊断效能进行了研究，以确定腓总神经麻痹是否由腓骨小头区域的神经受压所致。在47例有腓骨小头附近神经受压病史或提示神经受压病史的连续患者中，64%的患者通过沿腓骨小头处神经节段的感觉传导减慢确定了病变部位，而在18例腓总神经麻痹并非由腓骨小头处受压引起的患者中未出现假阳性结果。在沿穿过腓骨小头节段出现传导减慢的患者中，20%从上方支持带测量至腘窝时传导速度正常。沿运动纤维（趾短伸肌）传导减慢可在三分之一的患者中确定病变部位。与在腓骨小头远端记录的感觉反应相比，在腘窝记录的感觉反应的波幅和离散度差异的诊断价值有限，因为在腓总神经麻痹并非由腓骨小头处神经受压引起的患者中有许多假阳性结果。
