Description

technical field

[0001] The invention relates to a device in the technical field of rehabilitation engineering, in particular to a parallel multi-free artificial limb exoskeleton ankle joint. Background technique

[0002] In recent years, the number of physically disabled persons due to accidents such as traffic accidents, sports accidents, industrial injuries, wars and population aging has been increasing year by year. In the process of building a harmonious society, the physical and mental health of the disabled has received widespread attention from the whole society. At present, there are many types of medical equipment for rehabilitation training for patients. For patients with lower limb disabilities and paralysis, traditional rehabilitation tools include crutches, wheelchairs and artificial limbs. These three types are passive rehabilitation equipment, which are not convenient for patients to use, and sometimes they need help from other people. Artificial limbs have al...
