许多物理因子可以影响运动神经传导速度早有报道,但多属物理因子作用时导致体温改变继而影响神经传导速度。本文探讨了直流电作用对运动神经传导速度的影响。作者按三种方式通电,共10例健康受试者,直流通电前后当天进行运动神经传导速度检查.三种通电方式是:1.上肢并置法,两个200cm~2电极一置颈背部,一置前臂,分别用上行与下行流;2.用水电浴方式作用于上肢,极性交替改变;3.在神经走行的相应区作直流电肘 Many physical factors can affect motor nerve conduction velocity has long been reported, but mostly due to physical factors lead to changes in body temperature and then affect the nerve conduction velocity. This article discusses the effect of DC on motor nerve conduction velocity. The author energized in three ways, a total of 10 cases of healthy subjects, motor conduction velocity examination before and after DC power on.The three methods of electrification are: 1 upper limb collocation method, two 200cm ~ 2 electrode back home neck, A forearm, respectively, with the upstream and downstream; 2 water bath role in the upper limbs, alternating polarity changes; 3. nerve in the corresponding area for the DC elbow
