重复经颅磁刺激对恢复期脑卒中患者步行的效果

目的 探讨重复经颅磁刺激(rTMS)对恢复期脑卒中患者步行能力的效果。方法 2021年1月至2022年1月，福建中医药大学附属康复医院恢复期脑卒中住院患者60例，随机分为A组(n=20)、B组(n=20)和C组(n=20)。3组均接受常规康复治疗和下肢机器人训练，B组接受患侧第一躯体皮质运动区伪rTMS,C组接受患侧第一躯体皮质运动区高频rTMS，共4周。治疗前后采用Fugl-Meyer评定量表下肢部分(FMA-LE)、计时起立-行走测试(TUGT)和步态分析进行评定。结果 治疗后，3组FMA-LE评分、TUGT、步速、步宽、步幅、双支撑相时间、患侧支撑相时间、患侧摆动相时间、健侧支撑相时间和健侧摆动相时间均显著改善(|t|> 5.990, P <0.001)；除双支撑相时间外，C组所有指标均最优(F> 3.210, P <0.05)。结论 高频rTMS有助于改善恢复期脑卒中患者下肢运动功能和步行功能。

Effect of repetitive transcranial magnetic stimulation on walking of stroke patients at recovery stage

Objective To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on walking function of stroke patients at recovery stage. Methods From January, 2021 to January, 2022, 60 stroke inpatients at recovery stage from Rehabilitation Hospital Affiliated to Fujian University of Traditional Chinese Medicine were randomly divided into group A (n = 20), group B (n = 20) and group C (n = 20). All the groups accepted conventional rehabilitation therapy and lower limb robot-assisted training, while group B accepted pseudo-rTMS, and group C accepted high-frequency rTMS, for four weeks. They were assessed with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Timed 'Up and Go' Test (TUGT) and gait analysis before and after treatment. Results The score of FMA-LE, TUGT, pace, stride width, stride, double support phase time, affected side support phase time, affected side swing phase time, healthy side support phase time and healthy side swing phase time improved after treatment in all the groups (|t| > 5.990, P < 0.001), and all the indexes improved the most in group C (F > 3.210, P < 0.05), except double support phase time. Conclusion High-frequency rTMS could facilitate the recovery of lower limb function and walking of stroke patients at recovery stage.
