辅助上肢运动康复机器人技术研究

Robotic aid for upper limb rehabilitation

为了给上肢偏瘫患者的治疗提供有效的辅助工具,研制了一种新型神经康复机器人。该机器人采用二连杆机构模拟人体上肢,其中机器人大臂、小臂分别由两台伺服电机驱动,可以实现平面内的复合运动。另外,该机器人系统针对患者病情的不同阶段,可以提供相应的训练模式。对临床30名患者为期1个月的辅助治疗结果显示:病人对这种新的治疗方法不反感,上肢的运动功能得到明显改善,未发现其他副作用。

A robotic neuro-rehabilitation arm was developed for disabled upper limbs, The robot is made of two linkages which simulate the structure of the human upper limb. The big arm and the small arm of the robot are driven by two servo motors that enable movements in a plane. The robotic system has different training modes for different levels of impairment. Resuhs from 30 patients in a clinical trial for a month show that the patients can effectively use the prosthesis to improve upper limb movements without any bad effect.
