STRUCTURAL DESIGN AND ANALYSIS OF WEIGHT REDUCTION SUPPORT SYSTEM FOR LOWER LIMB REHABILITATION

For the patients with lower extremity motor dysfunction caused by stroke and aging,a new weight loss system for double axillary support lower limb rehabilitation based on barycentre trajectory of human body was developed.Firstly,the influence of weight loss support training on plantar pressure was analyzed and studied.Secondly,based on ergonomics theory and the study of barycentre trajectory of human body,the overall structure was analyzed and designed,and the relevant size was determined.Thirdly,the reliability of the structure was verified by statics analysis.Finally,the kinematics analysis and dynamic simulation of the weight reduction module were carried out.The system can help the patients with lower extremity motor dysfunction realize the rehabilitation training of imitating the normal walking.
