背景和目的：对于许多患者来说，克服脑血管意外（CVA）引起的慢性轻偏瘫具有挑战性，尤其是在CVA后的最初12个月。使用已建立的运动控制理论，本研究调查肌电图（EMG）触发的神经肌肉刺激和双边协调training. Methods-25 CVA受试者自愿参加这项运动恢复协议研究。受试者被随机分配到3组中的1组：（1）EMG触发刺激和双侧运动的耦合方案（n = 10）;（2）EMG触发刺激和单侧运动（n = 10）;或（3）对照组（n = 5）。所有参与者在2周的时间内完成了6小时的康复训练。在前测-后测控制组设计的3类运动任务的基础上，对手腕和手指的运动能力进行了评价。结果：（1）功能任务中移动的块数，（2）开始运动的计时反应时间，（3）肌肉的持续收缩能力均有利于双侧运动训练和肌电图的耦合。触发神经肌肉刺激方案组。此外，单边运动/刺激组超过了控制组的块移动和快速发作的肌肉contractions.Conclusions-This新的证据是令人信服的，在耦合协议组的受试者能够证明增强自愿运动控制跨3类任务。随着CVA患者运动功能的扩展，腕部和手指的慢性轻偏瘫明显减少。
Background and Purpose-Overcoming chronic hemiparesis from a cerebrovascular accident (CVA) can be challenging for many patients, especially after the first 12 months after the CVA. With the use of established motor control theories, the present study investigated electromyogram (EMG)-triggered neuromuscular stimulation and bilateral coordination training.Methods-Twenty-five CVA subjects volunteered to participate in this motor recovery protocol study. Subjects were randomly assigned to I of 3 groups: (1) coupled protocol of EMG-triggered stimulation and bilateral movement (n = 10); (2) EMG-triggered stimulation and unilateral movement (n = 10); or (3) control (n = 5). All participants completed 6 hours of rehabilitation during a 2-week period according to group assignments. Motor capabilities of the wrist and fingers were evaluated on the basis of 3 categories of motor tasks in a pretest-posttest control group design.Results-Significant findings for the (1) number of blocks moved in a functional task, (2) chronometric reaction times to initiate movements, and (3) sustained muscle contraction capability all favored the coupled bilateral movement training and EMG-triggered neuromuscular stimulation protocol group. In addition, the unilateral movement/stimulation group exceeded the control group in the number of blocks moved and rapid onset of muscle contractions.Conclusions-This new evidence is convincing in that subjects in the coupled protocol group were able to demonstrate enhanced voluntary motor control across 3 categories of tasks. Chronic hemiparesis decreased considerably in the wrist and fingers as CVA patients expanded their motor repertoire.
