摘要
目的观察肌萎缩侧索硬化(ALS)的电生理改变,并对其临床意义作初步评价。方法已确诊的36例ALS患者常规进行针极肌电图、神经传导速度、重复频率刺激试验检查,并对其结果进行分析。结果ALS的EMG表现为广泛的神经源性损害,如运动时限延长、波幅增高、纤颤电位、巨大电位等。小部分患者可出现感觉传导速度和运动传导速度减慢。部分患者存在重复频率刺激试验异常。结论神经电生理检查是辅助诊断的重要手段,并对了解其病生理机制有一定帮助。
Objective To observe the neural electrical pathological changes on amyotrophic la teral sclerosis(ALS)and to evaluate their clinical significance primarily.Methods Routin acu-electromyogram(EMG),nerve conduction velocity,repeated frequency stimulation test were carried on 36ALS patients and th e results were analysed.Results The EMG of ALS manifestated extensiv e injuries derived nerves,such as prolonged duration,high amplitu de,fribrillation potential,and huge potential etc.Small portion of patients had slow sensory or motor nerv e conduction velocity.Part patients had abnormal results of repeated fre quency stimulation test.Conclusion Neural electrical pathological ex-aminations are important assisted measures to ALS and are benefit to understand the pathological mechanism o f ALS.
