Brief summary
Evaluation of the effectiveness and safety of the lower extremity exoskeleton rehabilitation training robot
Detailed description
Evaluation of the effectiveness and safety of the lower extremity exoskeleton rehabilitation training robot developed by AI-Robotics Technology Co., Ltd., Beijing for who had lower limb paralysis
Interventions
DEVICEAiLegs, AiWalker and HKAFO
5 days. Using their own control method, each morning using AiLegs, AiWalker AiWalker and HKAFO for 6 minutes walk test, three kinds of appliance between at least 30 minutes to determine heart rate, blood pressure and breathing back to quiet level. Repeat the same procedure in the afternoon ，the order is also random. Each participant will complete 10 groups of lower limb exoskeleton rehabilitation Training robot (including AiLegs, AiWalker two models) and HKAFO 6 minutes walking test
