Design And Research Of The Lower Limb Gait Rehabilitation Training Device

With the increasing number of elderly people in China, natural disasters andaccidents, the number of patients with lower limb disabilities is becoming larger. Thedemand of patients for rehabilitation is becoming stronger. However, the shortage ofhealth care workers is difficult to achieve hand to hand treatment. The ordinary familiescan not afford the expensive rehabilitation training equipments, which is bound to affecttheir rehabilitation and normal life. Now, research on rehabilitation robot has become a hotspot for scholars and companies from various countries, but our research on rehabilitationrobots started later than foreign countries. Therefore, developing a functional lower limbrehabilitation robot is very necessary.This paper, based on the theory of clinical rehabilitation, proposed an ergonomiclower limb gait rehabilitation training devices, the devices is able to provide patients withnormal gait trajectory training, this paper, used optimization method to study the gaittrajectory generation mechanism synthesis.The equipment can meet the different needs of patients with providing them thepassive training, active assistance training, and impedance training. This paper, usedSolidworks to establish a physical prototype, introduced the selection of motor, reducer,electric putter etc. This paper gave a detailed description of the components design.This paper analyzed the kinematics and dynamics simulation of the lower limb gaitrehabilitation training devices, According to the normal gait, planed the motion of thepedal posture, created a virtual prototype model of human-machine simulation based onAdams, Got the human-machine parameters of the rehabilitation training, Designed a gaitanalysis system based the GUI of Matlab. You can easily calculate the correspondinginstitutions parameters of different gait. This paper got the different effects on patients indifferent gait rehabilitation training model.This paper, described the structures of control system, analyzed the training mode ofthe lower limb gait rehabilitation training devices.
