Description

technical field

[0001] The invention relates to the field of upper limb rehabilitation equipment, in particular to a forearm self-adaptive mechanism for a centrally driven upper limb rehabilitation robot. Background technique

[0002] With the aging of the global population and the increasing number of patients with neurological and musculoskeletal diseases, the demand for upper limb rehabilitation is also growing rapidly. The health care work for the elderly and patients is gradually being replaced by upper limb rehabilitation robots. When performing upper limb rehabilitation training, traditional upper limb rehabilitation robots cannot satisfy the slight rotation of the forearm during elbow flexion / extension training. At the same time, the fixed device designed on the forearm will cause patients to feel slight discomfort during training.

[0003] The adaptability of machine equipment plays a vital role in the development of human-computer interaction machines. Traditional ...
