基于虚拟现实的下肢主动康复训练系统
基于虚拟现实的下肢主动康复训练系统LI Wenxiao;GUO Bingjing;HAN Jianhan;LI Xiangpan;MAO Yongfei【摘要】针对传统下肢康复训练中病人参与度低、主动运动意图逐渐丧失的问题,设计一种基于虚拟现实的下肢主动康复训练系统.该系统采用惯性检测单元(IMU)获取并解算下肢关节活动度,作为虚拟场景中的运动控制信号,并建立无线蓝牙通信机制,把患者下肢运动与运动功能康复训练游戏结合在一起.基于鞋内置多点足底力传感器(FSR)获取患肢足底力参数,识别步态相周期,作为康复评估的数据基础.实验验证了康复数据获取的准确性、交互通信的实时性与康复场景运行的流畅性.【期刊名称】《现代电子技术》【年(卷),期】2019(042)004【总页数】5页(P61-64,70)【关键词】虚拟现实;主动康复;下肢康复训练;传感系统;活动度;足底力【作者】LI Wenxiao;GUO Bingjing;HAN Jianhan;LI Xiangpan;MAO Yongfei 【作者单位】;;;;【正文语种】中文【中图分类】TN915.5-34;TP274随着社会老龄化的加剧，由脑卒中等导致的神经损伤引起的下肢功能障碍者逐年增加[1]，严重影响患者的生活质量，给社会和家庭带来了沉重的负担。
传统的康复治疗多采用医师手工辅助完成，效率低、康复过程枯燥，已不能满足患者的需求[2]。
根据大脑神经可塑性理论、镜像神经元理论和运动康复理论，丰富的训练环境可以促进康复的进程[3]，也可以有效地提高患者的训练兴趣和积极性，从而提高康复效率。
如德国柏林弗朗霍费尔研究所研制Haptic Walker机器人系统和加拿大蒙特利尔McGill大学研究的多自由度反馈的下肢训练器；当前的下肢康复训练设备多为在医疗机构中使用，价格昂贵[4]，同时也需要医护人员的协助，缺乏可供患者使用的家庭便携式智能康复训练设备，不利于患者的自主训练。
