The aim of this paper is to compare the potentials from the extensor digitorum brevis (EDB) with those from the tibialis anterior (TA) stimulating the peroneal nerve proximally and distally the fibular head in patients suffering of peroneal nerve palsy at the fibular head. In 8/30 limbs the electrophysiological studies were normal. According to electrophysiological findings the lesion was of demyelinating type in 6/22 patients, axonal in 8/22 and mixed in 8/22. In 12/22 limbs the abnormalities were found recording both for EDB and TA muscles; in 7/22 recording only from EDB and in 3/22 recording only from TA. Thus it is possible that motor fibers supplying the EDB and TA may be damaged differently and is useful evaluate both muscles.
本文旨在比较在腓骨头处患有腓总神经麻痹的患者中，刺激腓骨头近端和远端的腓总神经时，来自趾短伸肌（EDB）和胫骨前肌（TA）的电位。在30条肢体中的8条，电生理研究结果正常。根据电生理结果，22例患者中6例为脱髓鞘型病变，8例为轴索性病变，8例为混合型病变。在22条肢体中的12条，记录到EDB和TA肌肉均有异常；22条中的7条仅记录到EDB异常，22条中的3条仅记录到TA异常。因此，支配EDB和TA的运动纤维可能受到不同程度的损伤，同时评估这两块肌肉是有用的。
