Method:Central motor conduction time (CMCT) was calculated by combining the magnetic stimulation motor evoked potentials (MEP) and electric stimulation F waves from the abductor pollicis brevis(APB) and the anterior tibialis (AT) in 19 patients with CSM.

• 方法：采用磁刺激运动诱发电位（MEP）和电刺激F波相结合的方法，测定19例脊髓型颈椎病人外展拇短肌（APB）和胫前肌（AT）的中枢运动传导时间（CMCT），并与20例正常受试者作对照。
