Excited areas of ankle active dorsiflexion involved the bilateral primary motor area and the primary somatosensory area, as well as the bilateral supplementary sensory area, the primary visual area, the right second visual area, and the vermis of cerebellum. Excited areas of ankle active plantar flexion included the ipsilateral supplementary motor area, the limbic system, and the contralateral corpus striatum. Fine movements of the cerebral cortex control the function of the ankle dorsiflexion to a larger extent than ankle plate flexion, and the function of ankle plate flexion is more controlled by the subcortical area.展开更多
目的:观察指压穴位刺激对早期脑卒中偏瘫患者踝背屈功能的影响。方法:45例偏瘫患者,随机分为指压穴位组、电针组和神经肌肉电刺激组各15例。3组在常规药物和物理治疗的基础上,指压穴位组增加前期系列研究制定的指压穴位刺激法提高偏瘫...目的:观察指压穴位刺激对早期脑卒中偏瘫患者踝背屈功能的影响。方法:45例偏瘫患者,随机分为指压穴位组、电针组和神经肌肉电刺激组各15例。3组在常规药物和物理治疗的基础上,指压穴位组增加前期系列研究制定的指压穴位刺激法提高偏瘫侧胫前肌、腓骨长短肌兴奋性的综合方案干预;电针组电针偏瘫侧足三里穴、足临泣穴;神经肌肉电刺激组电刺激偏瘫侧胫前肌、腓骨长短肌。3组踝关节干预时间均为每次10min,每天1次,每周5天,疗程8周。分别于治疗前、治疗4w后、治疗8w后,评估以下指标:患侧踝背屈协同收缩率(co-contraction ratio,CCR)、患侧踝背屈主动活动范围(active range of motion,AROM)、患侧简式Fugl-Meyer运动功能评分(踝关节运动控制部分)。结果:①3组治疗前后比较:3组的各项指标治疗前、治疗4w后、治疗8w后两两比较均有显著性差异(P<0.05),患侧踝背屈CCR逐步降低、患侧踝背屈AROM和简式Fugl-Meyer运动功能评分逐步增高;②3组间比较:患侧踝背屈CCR、AROM:3组间治疗前两两比较均无显著性差异(P>0.05);指压穴位组的治疗4w后、治疗8w后的患侧踝背屈CCR分别低于电针组、神经肌肉电刺激组,具有显著性差异(P<0.05),而AROM分别高于电针组、神经肌肉电刺激组,具有显著性差异(P<0.05);电针组较神经肌肉电刺激组的治疗4w后、治疗8w后均无显著性差异(P>0.05);简式Fugl-Meyer运动功能评分:3组间治疗前、治疗4w后、治疗8w后两两比较均无显著性差异(P>0.05)。结论:指压穴位刺激法可有效改善早期脑卒中偏瘫患者踝背屈功能。展开更多
