肌电图是利用电子仪器记录神经肌肉的生物电活动,也可用来测定周围神经传导速度;它可提供脊髓前角细胞、周围神经、神经肌肉接头和肌肉的某些功能状态,对于神经肌肉疾病和周围神经损伤的诊断、观察、治疗效果与推测其预后均有一定帮助。检查时常用针状或表面电极做引导,通过肌电图仪 EMG is the use of electronic instruments to record neuromuscular bio-electrical activity, can also be used to determine the peripheral nerve conduction velocity; it can provide spinal cord anterior horn cells, peripheral nerves, neuromuscular junction and some of the functional status of muscle, for neuromuscular diseases And peripheral nerve injury diagnosis, observation, treatment and prognosis of prognosis have some help. Inspection often use needle or surface electrode to guide, through the electromyograph
