感觉神经传导速度(SNCV)已在肌电图室常规应用,但是这常常仅限于数目有限的神经,而对那些不常检测的神经,如隐神经,其传导性能的参数可因不同的研究而有相当的差异。因此,有必要寻找更好的方法来研究这些不常检测的神经的传导性,并建立其正常值。在30名年龄在20～36岁的健康志愿者中,对一组不常被检测,甚至是极少被检测的感觉神经,采用顺(O)和逆行(A)技术,测定其动作电位潜伏期、幅度和传导速度的正常值。同时还测 Sensory nerve conduction velocity (SNCV) has been routinely used in electromyography rooms, but this is often confined to a limited number of nerves, whereas for less frequently detected nerves such as saphenous nerves the parameters of conduction properties can vary for different studies There are considerable differences. Therefore, there is a need to find better ways to study the conductivity of these infrequently-detected nerves and to establish their normal values. Among 30 healthy volunteers aged 20-36 years, a group of sensory nerves, which was seldom detected or even seldom detected, was subjected to cis (O) and retrograde (A) techniques to determine the latency of action potential , Amplitude and conduction speed of the normal value.
