摘要
针对踝关节康复训练装置存在内外翻功能不足的问题,根据踝关节运动机理对其进行优化设计,改进后的康复训练装置在机构上解决了现有训练装置采用3个标准旋转轴正交的运动结构与人体踝关节的复合运动存在偏差的问题,通过三维数字建模和3D打印完成了产品样机模型。为测试装置优化效果,设计了足底压力对照试验,结果发现,与市场主流康复训练装置相比,优化后的踝关节康复训练装置在使用过程中总体足底压力更小且压力值波动较小,证实优化后的踝关节康复训练装置更加符合人体踝关节的生理结构及运动机制。
In view of the current ankle joint rehabilitation training devices′valgus movement methods,an optimized model was designed,according to the ankle joint movement mechanism.The improved rehabilitation training device mechanically resolved the problem of deviation of the existing training device using three standard rotation axes orthogonal to the movement structure and the compound movement of the human ankle joint.The prototype model was built through three-dimensional digital modeling and 3 D printing.In order to test the effectiveness of the new device,a controlled plantar pressure experiment was designed.The experimental results show that the optimized rehabilitation training device has lower overall plantar pressure during use and more stable pressure fluctuations than the mainstream rehabilitation training devices in the market.It is verified that the optimized ankle joint rehabilitation training device is more consistent with the physiological structure of the human ankle joint and motion mechanism.
