背景：痉挛在中风患者中很常见。重复外周磁刺激(RPMS)是一种无痛、无创的治疗方法，是一种很有前途的减少痉挛的方法。然而，这种疗法的核心机制仍不清楚。RPMS干预后皮质活动的变化和痉挛程度的减少需要进一步的探讨。本研究旨在探讨RPM干预后脑卒中患者脑电MU节律的变化及痉挛程度的减少。材料和方法：32例卒中后痉挛患者被分成RPMS组和假手术组，每组16例。采用改良Ashworth评分、改良Tardieu评分和Fugl-Meyer上肢功能评分评价上肢痉挛状态和运动功能的变化。在RPMS干预前后进行脑电评估，检测脑电Mu节律的变化。结果：经过一次RPMS干预后，肘屈肌(P<；0.05)和腕屈肌(P<；0.05)的痉挛程度均有所降低。上肢运动功能按Fugl-Meyer评分改善(p<；0.05)。在RPMS组，对侧大脑半球MU节律频段(8-12赫兹)的事件相关去同步化功率降低(p<；0.05)。结论：RPMS干预可减少痉挛。大脑皮层活动的变化可能暗示了这种有利的变化，因为它对中枢神经系统产生了神经影响。
Background: Spasticity is common among patients with stroke. Repetitive peripheral magnetic stimulation (rPMS) is a painless and noninvasive therapy that is a promising approach to reducing spasticity. However, the central mechanism of this therapy remains unclear. Changes in cortical activity and decreased spasticity after rPMS intervention require further exploration. The aim of this study was to explore the electroencephalography (EEG) mu rhythm change and decrease in spasticity after rPMS intervention in patients with stroke. Materials and methods: A total of 32 patients with spasticity following stroke were recruited in this study and assigned to the rPMS group (n = 16) or sham group (n = 16). The modified Ashworth scale, modified Tardieu scale, and Fugl–Meyer assessment of the upper extremity were used to assess changes in upper limb spasticity and motor function. Before and after the rPMS intervention, EEG evaluation was performed to detect EEG mu rhythm changes in the brain. Results: After one session of rPMS intervention, spasticity was reduced in elbow flexors (p < 0.05) and wrist flexors (p < 0.05). Upper limb motor function measured according to the Fugl–Meyer assessment was improved (p < 0.05). In the rPMS group, the power of event-related desynchronization decreased in the mu rhythm band (8–12 Hz) in the contralesional hemisphere (p < 0.05). Conclusions: The results indicate that rPMS intervention reduced spasticity. Cortical activity changes may suggest this favorable change in terms of its neurological effects on the central nervous system.
