目的：观察重复任务训练与肌电支架(RTP+Myomo)相结合的8周训练方案对偏瘫上肢(在有价值的活动、感觉恢复和达到运动学方面的使用)的疗效。12名受试者(4名男性；平均年龄53.5岁；平均卒中后时间61.7个月)。7例患者接受RTP+Myomo治疗，5例患者仅接受RTP治疗。两组都参加了为期8周的个性化治疗，每周3天，每次45分钟。对干预前后的手臂、手能力、日常生活能力、卒中影响量表(SIS)的恢复子量表的知觉以及UE的到达运动学进行评估。RTP+Myomo组在SIS各分量表上均有较大改善，恢复量表达到统计学意义(p=0.03)。仅使用RTP组的受试者在上伸任务中手部速度有较大幅度的增加(p=0.02)，但在伸展过程中肩关节屈曲或肘部伸展的范围没有观察到变化。运动学结果指标的变化与SIS子量表的任何变化均无显著相关性。RTP结合肌电支持可能仅在改善自我报告功能和对总体恢复的看法方面比RTP更有益。我们没有观察到肘关节伸展范围的变化，也没有观察到自我报告的改善与伸展运动学变化之间的关系。
To examine the efficacy of an 8-week regimen combining repetitive task-specific practice with a myoelectric brace (RTP+Myomo) on paretic upper extremity (UE use in valued activities, perceived recovery, and reaching kinematics). Twelve subjects (4 males; mean age 53.5 years; mean time post stroke 61.7 months). Seven subjects were administered RTP+Myomo therapy, and 5 were administered RTP only. Both groups participated in individualized, 45-minute therapy sessions occurring 3 days/week over an 8-week period. The arm, hand ability, activities of daily living, and perceptions of recovery subscales of the Stroke impact Scale (SIS), as well as UE reaching kinematics, assessed before and after the intervention. Subjects in the RTP+Myomo group showed greater improvements on all SIS subscales, with the recovery scale reaching statistical significance (p=0.03). Subjects in the RTP-only group showed a greater increase in hand velocity in the reach up task (p=0.02), but no changes were observed in the range of shoulder flexion or elbow extension during reaching. None of the changes in kinematic outcome measures significantly correlated with any of the changes in SIS subscales. RTP integrating myoelectric bracing may be more beneficial than RTP only in improving self-reported function and perceptions of overall recovery. We observed no changes in the range of elbow extension, and no relationship between self-reported improvements and changes in reaching kinematics.
