用于中风患者运动障碍的神经康复的机器人设备已经被广泛研究。然而，这些器械中的绝大多数仅允许在临床中练习模拟功能任务的定型组件。之前，我们开发了SpringWear，这是一种可穿戴的弹簧操作上肢外骨骼，能够在现实生活中的功能活动中辅助运动，可能在家中。SpringWear辅助肩部屈曲、肘部伸展和前臂旋后/旋前。辅助轮廓被设计成近似于在其范围内被动地移动关节所需的扭矩。这三个辅助自由度与两个被动肩自由度相结合，允许复杂的多关节运动模式。我们进行了一项横断面研究，以评估在SpringWear的帮助下运动模式的变化。13名慢性中风患者进行了活动范围（ROM）和功能任务，包括各种物体的拾取和放置任务。设备上的传感器测量所有5个自由度的旋转，运动学模型计算手腕相对于肩部的位置。在SpringWear的帮助下，使用受试者内t检验来确定变化。在ROM和功能任务中，最大肩关节屈曲、肘关节伸展和前臂旋前/旋后角度均显著增加（p < 0.002）。肘关节屈曲/伸展ROM也显著增加（p < 0.001）。当受试者自愿举起手臂对抗重力时，在SpringWear的辅助下，食指近端指间关节的伸展显著增加（p = 0.033）。前伸工作空间增加了19%（p = 0.002）。9名受试者无法独立完成功能性任务，只有1名受试者在使用SpringWear完成任务方面有所改善。SpringWear增加了伸展运动期间的可用工作空间，但在完成功能性任务的能力方面没有持续的改善。肩部的辅助水平仅增加到肩部可以自愿保持90度屈曲。更高级别的援助可能会产生更好的结果。此外，将SpringWear与HandSOME（一种辅助手部张开的外骨骼）结合使用，可能会在功能性任务表现方面产生最显著的改善。这些低成本的设备可以潜在地减少工作量并提高任务练习期间的表现，增加对家庭康复训练计划的坚持。
Robotic devices for neurorehabilitation of movement impairments in persons with stroke have been studied extensively. However, the vast majority of these devices only allow practice of stereotyped components of simulated functional tasks in the clinic. Previously we developed SpringWear, a wearable, spring operated, upper extremity exoskeleton capable of assisting movements during real-life functional activities, potentially in the home. SpringWear assists shoulder flexion, elbow extension and forearm supination/pronation. The assistance profiles were designed to approximate the torque required to move the joint passively through its range. These three assisted DOF are combined with two passive shoulder DOF, allowing complex multi-joint movement patterns. We performed a cross-sectional study to assess changes in movement patterns when assisted by SpringWear. Thirteen persons with chronic stroke performed range of motion (ROM) and functional tasks, including pick and place tasks with various objects. Sensors on the device measured rotation at all 5 DOF and a kinematic model calculated position of the wrist relative to the shoulder. Within subject t-tests were used to determine changes with assistance from SpringWear. Maximum shoulder flexion, elbow extension and forearm pronation/supination angles increased significantly during both ROM and functional tasks (p < 0.002). Elbow flexion/extension ROM also increased significantly (p < 0.001). When the subjects volitionally held up the arm against gravity, extension at the index finger proximal interphalangeal joint increased significantly (p = 0.033) when assisted by SpringWear. The forward reach workspace increased 19% (p = 0.002). Nine subjects could not complete the functional tasks unassisted and only one showed improvement on task completion with SpringWear. SpringWear increased the usable workspace during reaching movements, but there was no consistent improvement in the ability to complete functional tasks. Assistance levels at the shoulder were increased only until the shoulder could be voluntarily held at 90 degrees of flexion. A higher level of assistance may have yielded better results. Also combining SpringWear with HandSOME, an exoskeleton for assisting hand opening, may yield the most dramatic improvements in functional task performance. These low-cost devices can potentially reduce effort and improve performance during task practice, increasing adherence to home training programs for rehabilitation.
