Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training equipment, in particular to an intelligent rehabilitation wheelchair robot for assisting standing. Background Art

[0002] Walking exercise therapy is a treatment method that uses walking as a means of rehabilitation. It aims to improve the patient's physical function and health through regular walking activities. It is mainly aimed at patients who need walking exercise rehabilitation training due to lower limb movement disorders and postoperative rehabilitation caused by stroke, spinal cord injury, trauma, etc., as well as elderly people who cannot stand and have difficulty walking due to declining physical function.

[0003] Traditional walking exercise therapy emphasizes inducing separation movement of lower limb joints and separately training decomposed movements such as walking, balance, and center of gravity transfer. However, the real walking environment is different from this, and the result often leads to the contradictory phenomenon that patients have good separation movement but poor walking ability. In addition, hemiplegic patients rely more on the healthy limbs to bear weight because the affected limbs cannot bear enough weight. The manifestation is that the support period of one limb on the affected side is significantly shortened, while the support period of both limbs is significantly prolonged, which affects the conversion of kinetic energy and potential energy during walking, making the gait intermittent and not smooth. After rehabilitation, the walking is unbalanced, which may cause other hazards caused by severe spinal deformity. Therefore, an intelligent rehabilitation wheelchair robot for assisting standing is needed. Utility Model Content
