Hand impairment is common following stroke and is often resistant to traditional therapy methods. Successful interventions have stressed the importance of repeated practice to facilitate rehabilitation. Thus, we have developed a servo-controlled glove to assist extension of individual digits to promote practice of grasp-and-release movements with the hand. This glove, the PneuGlove, permits free movement of the arm throughout its workspace. A novel immersive virtual reality environment was created for training movement in conjunction with the device. Seven stroke survivors with chronic hand impairment participated in 18 training sessions with the PneuGlove over 6 weeks. Overall, subjects displayed a significant 6-point improvement in the upper extremity score on the Fugl-Meyer assessment and this increase was maintained at the evaluation held one month after conclusion of all training (p < 0.01). The majority of this gain came from an increase in the hand/wrist score (3.8-point increase, p < 0.01). Thus, the system shows promise for rehabilitative training of hand movements after stroke.
手部功能障碍在中风后很常见，并且往往对传统治疗方法有抵抗性。成功的干预措施强调了重复练习对促进康复的重要性。因此，我们开发了一种伺服控制手套，以协助单个手指伸展，促进手部抓握和松开动作的练习。这种手套，即气动手套，允许手臂在其整个工作空间内自由移动。我们创建了一个新颖的沉浸式虚拟现实环境，与该设备一起用于训练动作。七名患有慢性手部功能障碍的中风幸存者在6周内使用气动手套参加了18次训练课程。总体而言，受试者在Fugl-Meyer评估中的上肢得分显著提高了6分，并且在所有训练结束后一个月进行的评估中，这一提高得以保持（p < 0.01）。这一改善的大部分来自手/腕部得分的提高（提高了3.8分，p < 0.01）。因此，该系统在中风后手动作的康复训练方面显示出前景。
