A functional electrical stimulation (FES)-robot system controlled by subjects' motor intention was developed in our previous study. The effectiveness of the FES-robot on wrist training was investigated in this work. Five hemiplegic subjects with chronic stroke were recruited for an FES-robot assisted wrist training with 20 sessions. After the training, motor improvements were found in the wrist and fingers, represented by significant increase (P < 0.05) in clinical scores of the Fugl-Meyer Assessment (FMA), the Action Research Arm Test (ARAT), and the Modified Ashworth Score (MAS). Muscle coordination in the upper limb was also improved during the training as assessed by electromyography. The increased ARAT scores suggested improved upper limb motor functions, especially in the hand and fingers, compared to no improvement in previous study with only interactive robot-assisted wrist training without FES.
在我们之前的研究中，开发了一种由受试者运动意图控制的功能性电刺激（FES）-机器人系统。在这项工作中，研究了FES-机器人在手腕训练方面的有效性。招募了5名患有慢性中风的偏瘫受试者，进行20节次的FES-机器人辅助手腕训练。训练后，在手腕和手指方面发现了运动改善，表现为Fugl-Meyer评估（FMA）、动作研究臂测试（ARAT）和改良Ashworth评分（MAS）的临床评分显著提高（P<0.05）。通过肌电图评估，训练期间上肢的肌肉协调性也得到了改善。与之前仅进行无FES的交互式机器人辅助手腕训练的研究中没有改善相比，ARAT评分的提高表明上肢运动功能得到改善，尤其是在手和手指方面。
