高频重复经颅磁刺激对后遗症期脑卒中后吞咽功能障碍的疗效观察

Therapeutic Effect of High Frequency Repetitive Transcranial Magnetic Stimulation on Deglutition Disorders after Sequelae Stroke

目的探讨高频重复经颅磁刺激对后遗症期脑卒中后吞咽功能障碍患者疗效。方法选取2017年1月～2018年6月本院收治的40例后遗症期脑卒中后吞咽功能障碍患者为研究对象,采用电脑产生随机数字法将患者分为观察组和对照组,各20例。两组患者均接受常规吞咽功能训练,观察组患者在此基础上加用经颅磁刺激治疗,对照组患者接受同样刺激参数的假刺激线圈给予的治疗,比较两组患者吞咽功能评分及环咽肌表面肌电图最大波幅变化情况。结果治疗后,对照组、观察组患者吞咽功能评分分别为(4.10±0.59)分、(4.65±0.64)分,差异无统计学意义(P>0.05);环咽肌表面肌电图最大波幅值分别为(668.00±39.33)μV、(761.00±43.61)μV,组间比较,差异无统计学意义(P>0.05)。结论高频重复经颅磁刺激对后遗症期脑卒中后吞咽功能障碍患者的吞咽功能无明显改善。

Objective To investigate the efficacy of high-frequency repetitive transcranial magnetic stimulation in patients with deglutition disorders after stroke in sequelae.Methods 40 patients with deglutition disordersafter stroke in our hospital from January 2017 to June 2018 were enrolled. The patients were divided into observation group and control group by computer-generated random number method.20 cases each. Both groups of patients received routine group were treated with transcranial magnetic stimulation. The patients and the stimulation was given. The swallow function scores and the swallowing function training.The patients in the observation n the control group received the same stimulation parameters maximal amplitude of the surface electromyogram of the pharyngeal muscle were compared between the two groups. Results After treatment, the swallowing function scores of the control group and the observation group were（4.10±0.59）score and （4.65±0.64）score, respectively,the difference was not statistically significant （P〉0.05）.The maximum amplitude of the surface electromyogram of the pharyngeal muscle was （668.00±39.33）FV, （761.00±43.61）FV, and there was no significant difference between the groups （P〉0.05）. Conclusion High-frequency repetitive transcranial magnetic stimulation has no significant improvement in swallowing function in patients with deglutition disorders after sequelae.
