21例外伤后周围神经功能障碍的ENMG分析

ELECTRONEUROMYOGRAPHICAL ANALYSIS OF PERIPHERAL NERVE DYSFUNCTION AFTER TRAUMA

对21例外伤后“周围神经功能障碍”的神经肌电图（ENMG）特征进行分析，并探讨其在法医学鉴定中的意义。结果提示：癔症患者的ENMG中运动单位电位（MUP）较少，甚至引不出，运动神经传导速度（MNCV）和感觉神经传导速度（SNCV）基本正常或轻度减慢；夸大病情者的ENMG有正常或轻度异常，个别病倒在一部分或局部肌肉可出现神经损害的表现，但并非像他们所表现或诉说的那样严重、范围那样大；诈病者的ENMG一般在正常范围，ENMG检查可提供判断神经肌肉损伤真伪的依据。

The characteristics of electroneuromyogram(ENMG) of peripheral nerve dysfunction in 21 traumatic cases were analysed. The results indicated that the motor unit potential(MUP) in ENMG of hysteriac was few or even was not detected; The conduction velocity of motor and sensory nerve (MNCV and SNCV) was normal or slightly slow. ENMG of exaggerator is normal or slightly abnormal. In few cases, the nerve functional disorder may appeared in local rnuscle, but not in accordance with what they complained.
