Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and particularly to an upper limb rehabilitation training device for stroke patients. Background Art

[0002] The clinical manifestations of stroke patients mainly include mental disorders, motor, sensory, and language disorders. After a period of treatment, except for being conscious, the rest will still exist to varying degrees, and these symptoms become sequelae. Common sequelae include central paralysis, peripheral paralysis, hemiplegia, etc. Therefore, in the treatment of stroke, not only drugs and surgery are needed, but also patients need to strengthen physical training for assistance. The physical training content in stroke rehabilitation treatment includes upper limb rehabilitation training.

[0003] Traditional rehabilitation training is carried out by rehabilitation physicians to provide one-on-one artificial assistance to patients. However, due to the difficulty of stroke rehabilitation and the long duration of rehabilitation training, many patients choose home training, making it difficult to achieve one-on-one artificial assistance training, and the cost of artificial assistance training is also high. Existing home upper limb rehabilitation training equipment has relatively simple functions; and during upper limb rehabilitation training, the hand is prone to slipping due to the influence of the disease, resulting in poor training effects.
