【摘要】：目的研制老年人三维本体感觉测试系统。方法采用惯性传感技术研制一套基于三轴加速度计、三轴磁力计、三轴陀螺仪传感器的姿态测量系统,通过卡尔曼滤波进行数据融合,使该系统可以输出较高精度的姿态角数据。将受试者测试关节的近端环节固定,惯性传感器通过绑带固定在测试关节的远端环节上。惯性传感器在远端环节运动过程中与其做相同的运动,并记录下实时变化的三维角度值,即关节活动角度值。记录本体感觉测试常用方法——角度重建法中三维的目标角度、重建角度等数据。结果采用国际公认的本体感觉测试装置BIODEX测试系统测试8名男性老年人膝关节本体感觉测试结果与该测试系统获得的结果没有显著差异。结论老年人三维本体感觉测试系统能够测试老年人各关节的三维本体感觉,尤其是可以测试小关节本体感觉,能方便携带到康复大厅、病房等场合,在老年人健康评估、康复进程监控、伤残评定等多个方面都有非常重要的应用。
[Abstract]:Objective to develop a three dimensional measurement system for body sensation of the elderly. Methods an attitude measurement system based on three axis accelerometers, three axis magnetometers and three axis gyroscopes was developed by means of inertial sensing technology, and the data fusion was carried out by Kalman filter. The system can output high precision attitude angle data. The inertial sensor is fixed on the distal segment of the test joint by binding. The inertial sensor does the same motion as it does during the distal link motion, and records the real-time change in the three-dimensional angle value. That is, the angle of motion of the joint. The three-dimensional angle of the object is recorded in the method of angle reconstruction, which is commonly used in the measurement of proprioceptive sensation. Results there was no significant difference between the test results of knee joint proprioceptive sensation of 8 elderly men and the results obtained by the system. The three-dimensional proprioceptive test system of the elderly can test the three-dimensional proprioceptive sensation of each joint of the elderly. Especially can test the facet joint proprioceptive sense, can conveniently carry to the rehabilitation hall, ward and other occasions, in the elderly health assessment, rehabilitation process monitoring, disability assessment and other aspects of a very important application.
