To assist bedridden patients to do rehabilitation exercise in bed, a kind of adjustable rehabilitation training device was designed and kinematic analysis was performed on the model of this device. It is shown that this device can generate trajectory similar to the ankle trajectory of normal gait. Based on the analysis, the human–machine integrated model was then built and biomechanical analysis was applied on it by AnyBody Modeling System. Regarding the forces of some mainly used muscles as study object, the mapping relationships between patient’s posture and tendon forces under the same conditions were analyzed, all these results suggested that this novel device has the capacity to train different muscles with the most appropriate postures and thus it has the potential application in future.

一种用于卧床病人康复的新型步态训练设备

为帮助卧床病人在床上进行康复锻炼，设计了一种可调节的康复训练装置，并对该装置模型进行了运动学分析。结果表明，该设备可以产生类似于正常步态的踝关节轨迹的轨迹。在分析的基础上，建立人机一体化模型，并通过AnyBody Modeling System对其进行生物力学分析。以部分主要使用肌肉的受力为研究对象，分析了相同条件下患者体位与肌腱受力的映射关系，结果表明该新型器械能够以最合适的体位训练不同的肌肉，从而它在未来有潜在的应用。
