The impact of electromyographic biofeedback (EMG BFB) applied during functional gait activities and employed in accord with theories on motor learning was investigated in a chronic hemiplegic patient.
A single-subject A-B design was used. EMG BFB was applied to the triceps surae during gait. A rehabilitation program with a fading frequency of BFB application and an increasing variability in the task training was implemented. Responses to the rehabilitation program were documented via multiple quantitative gait analyses, performed during a baseline, treatment, and at follow-up 6 weeks after the end of treatment.
From baseline to end of treatment, there were significant changes in ankle power at push-off, both in amplitude and timing, as well as onset of ankle power at push-off relative to heel strike of the healthy leg. There was a significant increase in gait velocity, step length of the healthy side, stride length, and stride frequency. At follow-up, changes were still significantly different from baseline and the patient had reduced the use of the cane in activities of daily living.
BFB appears to have been effective in promoting positive changes in gait in this pilot study. The rehabilitation protocol also appeared to be effective in promoting learning and the incorporation of trained activities into daily activities.
在一名慢性偏瘫患者中，研究了在功能性步态活动期间应用并符合运动学习理论的肌电图生物反馈（EMG BFB）的影响。
采用单受试者A-B设计。在步态期间对腓肠肌三头肌应用EMG BFB。实施了一个康复计划，其中BFB应用的频率逐渐降低，任务训练的变异性逐渐增加。通过在基线、治疗期间以及治疗结束后6周的随访期间进行的多次定量步态分析，记录对康复计划的反应。
从基线到治疗结束，蹬离时踝关节力量在幅度和时间方面以及相对于健侧足跟触地的蹬离时踝关节力量起始均有显著变化。步态速度、健侧步长、步幅和步频显著增加。在随访时，变化仍与基线有显著差异，并且患者在日常生活活动中减少了拐杖的使用。
在这项初步研究中，BFB似乎有效地促进了步态的积极变化。康复方案似乎也有效地促进了学习以及将训练活动纳入日常活动。
