    Author: Zhu G, Shen Y.
    Journal: Fa Yi Xue Za Zhi; 2000 Nov; 16(4):196-7, 200, S1. PubMed ID: 12536964.
    Abstract:
    This study aims to explore a method to record and analyze motor evoked potentials (MEP) of upper limbs. Compound muscle action potentials (CMAP) are recorded from abductor digiti minimi (ADM) and abductor pollicis brevis (APB) by magnetic stimulation of human brain and peripheral nervous. Results show that the latency of left and right Cz-APB is 25.23 ms and 25.19 ms respectively. The difference of the bilateral latencies is 2.24 ms. The rate of amplitude, the rate of area for bilateral sides is 0.45 and 0.37. The left and right central conduction time (CCT) of Cz-APB is 11.79 ms and 11.75 ms. The bilateral difference is 2.00 ms. The latency of left and right Cz-ADM is 25.23 ms and 25.19 ms respectively. The difference of bilateral latencies is 2.24 ms. The rate of amplitude, the rate of area for bilateral sides is 0.45 and 0.37. The left and right CCT of Cz-ADM is 11.79 ms and 11.75 ms. The bilateral difference is 1.86 ms.
