Abstract
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.
