功能性电刺激与镜像治疗结合的手功能康复装置的设计

Design of hand function rehabilitation device based on mirror therapy and functional electrical stimulation

目的:设计一款新型的基于功能性电刺激与镜像治疗结合的手功能康复装置,辅助训练弛缓瘫期患者抓握能力,并增强镜像治疗中的视觉反馈。方法:通过健侧手佩戴传感器手套,检测手功能运动情况,并在显示终端输出同步动作三维手,同时予患手以预设的功能性电刺激处方,刺激手臂部肌肉组织,诱发手部肌肉自主运动以达到康复功能训练,并将患者手部抓握角度信息与电刺激康复运动信息记录于后台数据库中。结果:设备能按设计要求完成功能性电刺激结合镜像治疗对患者脑卒中后手运动功能的康复训练,实现手指运动角度等数据监测及三维手部模型实时反馈的设计目标,在患者健侧手的运动数据达到程序预设参数时,给予患侧手功能性电刺激。结论:该上肢康复设备能基本实现预期功能,设计合理,方案可行。

Objective: To enhance the efficacy of mirror therapy, a newly Hand Function Rehabilitation Device Based on Mirror Therapy and functional electrical stimulation (FES) is designed to help function rehabilitation training on grab ability of stroke patients. Method: The glove with sensors which could detect the healthy hand movements and output 3D hand models synchronically on terminal was used. The device gave a prescriptived FES to stimulate the forearm muscle, and the information of the patient's hand movement angle recorded in database at the same time. Result: Combining mirror therapy and FES, the device can monitor the finger movement angles and real-time feedback of 3D hand models as designed. It can give appropriate FES following the healthy hand angle preset. Conclusion: The device can help in completing hand function rehabilitation training of stroke patients.
