The Design of an Adjustable Rehabilitation Bed based on Human Biomechanics

To assist bedridden patients to do rehabilitation exercise, a kind of adjustable rehabilitation bed was designed. Then the human-machine integrated model was built and biomechanics analysis was applied on it. The human-machine integrated analysis model was built by AnyBody Modeling System, and a series of simulation experiment were carried out by using this model. Regarding the forces of some mainly used muscles as study object, the mapping relationship between patient’s gesture and tendon forces under same conditions was analyzed, and the most appropriate gestures for patients to train different muscles were found out.
