【摘要】：目的:明確振動對大腦皮質(zhì)運動區(qū)興奮性傳導的作用。方法:將20例腦梗死患者隨機分為A、B組,A組給予頻率7Hz,振幅7mm的振動治療,B組給予頻率14Hz,振幅7mm的振動治療。通過經(jīng)顱磁刺激下的運動誘發(fā)電位(MEP),記錄A、B兩組患者在振動治療前、后及治療1h后大腦感覺運動皮質(zhì)區(qū)的MEP皮質(zhì)潛伏期及中樞運動傳導時間(CMCT)。比較治療前后MEP皮質(zhì)潛伏期及CMCT的變化。結(jié)果:與振動刺激前比較,7Hz的振動刺激在治療后即刻及1h后的MEP皮質(zhì)潛伏期及CMCT雖然均有縮短趨勢,但只有1h后的CMCT有顯著性改善(P0.05);而14Hz組在治療后即刻的MEP皮質(zhì)潛伏期和CMCT均有顯著性差異(P0.05),1h后CMCT也較治療前顯著改善(P0.05)。結(jié)論:7Hz和14Hz的振動刺激可明顯提高患者受損腦區(qū)興奮性,且14Hz的振動刺激更有效。
[Abstract]:Objective: to investigate the effect of vibration on excitability conduction in motor area of cerebral cortex. Methods: 20 patients with cerebral infarction were randomly divided into two groups: group A (7 Hz) and group B (amplitude 7mm), group B (14 Hz) and group B (amplitude 7mm). Motor evoked potential (MEP),) was recorded by transcranial magnetic stimulation (MEP),). The latency of MEP cortex and central motor conduction time (CMCT).) in cerebral sensory motor cortex were recorded in two groups before, after and 1 hour after vibration therapy. The latency of MEP cortex and the changes of CMCT were compared before and after treatment. Results: compared with the pre-vibration stimulation, the latency of MEP cortex and CMCT of 7Hz immediately after treatment and 1h after treatment were shortened, but only the CMCT of 1h after treatment was significantly improved (P0.05). In 14Hz group, the cortical latency and CMCT of MEP were significantly different immediately after treatment (P0.05), and the CMCT was also improved after 1h (P0.05). Conclusion: the vibration stimulation of 7Hz and 14Hz can significantly increase the excitability of the injured brain area, and the vibration stimulation of 14Hz is more effective.
