Patients who suffer from stroke often experience synergistic movements that make completion of activities of daily living (ADL) difficult. Robotics is useful for therapy for these patients due to providing varying levels of assistance to complete tasks or promoting more efficient movements through targeted resistance. A 5 degrees of freedom upper extremity low impedance exoskeleton (ULIX) was developed for stroke therapy. Various therapy modes were tested with three chronic stroke patients with abnormal synergies. Increased support and assistance led to improved hand opening force and completion of tasks. EMG data had positive changes in the biceps and extensor digitorum. Targeted resistance to certain joints led to improved arm trajectories.
中风患者常常会出现协同运动,这使得他们难以完成日常生活活动(ADL)。机器人技术对于这些患者的治疗很有用,因为它可以提供不同程度的辅助来完成任务,或者通过有针对性的阻力促进更高效的运动。一种用于中风治疗的5自由度上肢低阻抗外骨骼(ULIX)被研发出来。针对三名存在异常协同作用的慢性中风患者测试了各种治疗模式。增加支撑和辅助导致手部张开力量得到改善以及任务得以完成。肌电图(EMG)数据在肱二头肌和指伸肌方面出现了积极变化。对某些关节施加有针对性的阻力导致手臂轨迹得到改善。
