磁刺激在其作用和刺激深部神经及脑方面优于电刺激,并无不适感觉.可用在刺激腰背神经根、颈神经根和运动皮层.但是目前认为用大圈磁刺激进行常规的周围神经传导研究不太合适,由于高选、择性超大量刺激难以达到,刺激的部位不确切.为了确定磁圈是否平行固定在周围神经表面的皮肤上,分别用大磁圈、小磁圈及电刺激神经的1～2点,测量M 波和H 波的潜伏时.
Magnetic stimulation in its role and stimulation of deep nerves and brain better than electrical stimulation, no discomfort, can be used to stimulate the dorsal root, cervical nerve root and motor cortex, but now that the use of large magnetic stimulation of the conventional peripheral nerve Conduction research is not appropriate, due to high election, a large number of selective stimulation is difficult to achieve, stimulation of the site inaccurate.In order to determine whether the magnetic circle parallel to the peripheral nerve surface of the skin, respectively, with a large magnetic ring, a small magnetic ring and electricity Nerve 1 to 2 points to measure the latency of M wave and H wave.
