| 摘要
目的：明确振动对大脑皮质运动区兴奋性传导的作用。
方法：将20例脑梗死患者随机分为A、B组，A组给予频率7Hz, 振幅7mm的振动治疗，B组给予频率14Hz，振幅7mm的振动治疗。通过经颅磁刺激下的运动诱发电位（MEP），记录A、B两组患者在振动治疗前、后及治疗1h后大脑感觉运动皮质区的MEP皮质潜伏期及中枢运动传导时间（CMCT）。比较治疗前后MEP皮质潜伏期及CMCT的变化。
结果：与振动刺激前比较，7Hz的振动刺激在治疗后即刻及1h后的MEP皮质潜伏期及CMCT虽然均有缩短趋势，但只有1h后的CMCT有显著性改善(P<0.05)；而14Hz组在治疗后即刻的MEP皮质潜伏期和CMCT均有显著性差异(P<0.05)，1h后CMCT也较治疗前显著改善(P<0.05)。
结论：7Hz和14Hz的振动刺激可明显提高患者受损脑区兴奋性，且14Hz的振动刺激更有效。 |

| Abstract
Objective: To investigate the effects of local vibration on motor cortex activity in the patients with stroke.
Method: Twenty patients with stroke were randomly divided into group A(10 cases) and group B(10 cases). Group A received low frequency local vibration treatment (7Hz, 7mm), while group B were given high frequency local vibration treatment (14Hz, 7mm). The MEP-induced cortex latency and CMCT of these two groups were recorded before, after and 1 hour after treatment by using repetitive transcranial magnetic stimulation (rTMS). Comparisons were performed between pre-treatment, post-treatment or pretreatment and 1 hour after treatment.
Result: Compared with pre-treatment, CMCT recorded 1 hour after treatment of group A was significantly lower. However, other indexes of group A had no significant changes after treatment. MEP-induced cortex latency and CMCT of group B were reduced after local vibration treatment. However, MEP-induced cortex latency in post-treatment had no significant differences.
Conclusion: Local vibration stimulation could increase the activity of damaged cerebral cortex in the patients with stroke. High-frequency local vibration was more efficient. |
