传导阻滞(ConductionBlock)是指神经冲动沿着完好的神经纤维传导时受到阻碍。它是评价周围神经功能状态的重要电生理学参数之一。传导阻滞是脱髓鞘所致的生理性结果之一,也是多发性硬化等脱髓鞘神经病中诸多的异常临床表现的生理基础。Kaji等对传导阻滞提出一种新的观点,以论述 Conduction block refers to the nerve impulses along the intact nerve fibers are impeded. It is one of the important electrophysiological parameters to evaluate the functional status of peripheral nerves. Conduction block is one of the physiological consequences of demyelination, but also the physiological basis of many abnormal clinical manifestations of demyelinating neuropathy such as multiple sclerosis. Kaji et al. Proposed a new perspective on conduction block to be discussed
