Itcan simulate the motion ofnormal human's laying gesture and give the patients healing training which will help them torecover from illness. The main topic ofthis study isdesigning akind rehabilitation machine which can meet the need after knee surgery. The main topic ofthis study isdesigning akind rehabilitation machine which has avirtual hip shaft features The paper atfirst systematically overviews the developing and application situation ofrehabilitative machine ,and puts forward the overall structure scheme for horizontal lower limbs rehabilitative machine. The double parallelogram structure that designed can meet the design requirements . Inaddition ,the kinematics models and the kinematical analysis ofthe Lower Limbs Rehabilitative machine are introduced concisely. Onthis foundation ,the movement process ofthe gait ’sequipment issimulated ,which provides the theoretic basis ofoptimization designing.
