目的探讨神经电生理检查对踝管综合征(TTS)患者的诊断价值.方法对26例临床拟诊的踝管综合征患者进行运动神经传导速度(MCV)、感觉神经传导速度(SCV)、F波及肌电图(EMG)检查,并对结果进行分析.结果 26例患者中,单侧受累22例,双侧受累4例,共对30群受累神经进行神经电生理检测.经运动神经传导检测,30条胫后神经中异常28条,异常率为93.3％;经感觉神经传导检测,30条足底内侧神经中异常27条,异常率90％;30条患侧足底外侧神经中异常24条,异常率80％;经EMG检测,踝管内神经相关肌肉156块,90块肌肉出现异常自发活动(57.7％),12块肌肉出现高大电位(7.7％),76块肌肉出现募集相减少(48.7％).结论踝管综合征为胫后神经远端病变,以轴索损害电生理改变为主.神经电生理检查对踝管综合征的诊断、鉴别诊断及指导治疗有重要价值.

Objective To investigate the diagnostic value of electrophysiological examination for tarsal tunnel syndrome (TTS).Methods Motor nerve conduction velocity (MCV),sensory nerve conduction velocity (SCV),F wave and electromyographic measurements were carried out with 26 clinically suspected TTS patients.Results Of the 26,22 patients were unilaterally affected and 4 were bilaterally affected,so 30 tarsal tunnels in total were affected.All received electrophysiological examination.Of the 30 affected tarsal tunnels,abnormal MCV was detected in 28 of the posterior tibial nerves (93.3％),while abnormal SCV was detected in 27 medial plantar nerves (90％) and 24 lateral plantar nerves (80％).Needle electromyography of 156 targeted foot muscles detected abnormal spontaneous potentials in 90 of them (57.7％),giant potential in 12 muscles (7.7％) and decreased recruitment in 76 (48.7％).Conclusions The distal posterior tibial nerve is impaired in TTS,presenting axonal damage in an electrophysiological examination.Such examinations should have an important role in the diagnosis and differential diagnosis of TTS.
