Description

technical field

[0001] The present application relates to the field of exoskeleton technology, in particular to a control method and device for a hip joint exoskeleton. Background technique

[0002] As the elderly grow older, their physical functions decline, and there are problems such as slow gait, small stride length, and difficulty in walking for a long time caused by insufficient lower limb muscle strength; patients with stroke and other diseases are prone to muscle atrophy, gait disorder, etc. Problems such as lower limb movement disorders require a lot of rehabilitation training to restore and maintain the basic functions of the limbs. After completing phased rehabilitation training in the hospital, they need to continue to maintain lower limb training at home in daily life to better restore lower limb movement. ability.

[0003] In terms of auxiliary nursing care for the elderly, traditional manual nursing services are likely to cause dependence on the elderly, and ...
