摘要
脑卒中后偏瘫患者常出现步态对称性受损，严重影响其运动功能和生活质量，而传统康复训练在改善步态对称性方面存在局限性。本研究旨在探讨镜像反馈疗法对脑卒中偏瘫患者步态对称性的纠正效果及其潜在机制。研究选取60例脑卒中偏瘫患者，随机分为实验组和对照组，实验组接受镜像反馈疗法结合常规康复训练，对照组仅接受常规康复训练，干预周期为12周。通过三维步态分析系统评估患者的步态参数，包括步长、步速、支撑相时间比值等指标，并采用功能性步行量表（FWS）评估步行能力。结果显示，实验组在步长差值、支撑相时间比值及步速等方面显著优于对照组（P0.05），且FWS评分提升更为明显。这表明镜像反馈疗法能够有效改善脑卒中偏瘫患者的步态对称性，其创新点在于利用视觉反馈与运动控制的协同作用，促进患侧肢体的主动参与和神经可塑性重建，为脑卒中步态康复提供了新思路。关键词：脑卒中偏瘫；镜像反馈疗法；步态对称性；视觉反馈；神经可塑性重建
Mirror Feedback Therapy for Correcting Gait Symmetry in Stroke Hemiplegia Patients
Abstract
Gait symmetry impairment is commonly observed in hemiplegic patients after stroke, which severely affects their motor function and quality of life. However, traditional rehabilitation training has limitations in improving gait symmetry. This study aimed to investigate the corrective effects of mirror feedback therapy on gait symmetry in stroke-induced hemiplegic patients and its potential mechanisms. A total of 60 hemiplegic patients post-stroke were randomly divided into an experimental group and a control group. The experimental group received mirror feedback therapy combined with conventional rehabilitation training, while the control group only underwent conventional rehabilitation training, with an intervention period of 12 weeks. Patients' gait parameters, including stride length, walking speed, and stance phase time ratio, were assessed using a three-dimensional gait analysis system, and functional walking ability was evaluated using the Functional Walking Scale (FWS). The results showed that the experimental group significantly outperformed the control group in terms of stride length difference, stance phase time ratio, and walking speed (P0.05), with a more pronounced increase in FWS scores. These findings indicate that mirror feedback therapy can effectively improve gait symmetry in hemiplegic patients after stroke. Its innovation lies in the synergistic use of visual feedback and motor control, promoting active participation of the affected limb and neural plasticity reconstruction, thus providing a new approach for gait rehabilitation in stroke patients.
