Description

Technical Field

[0001] The utility model belongs to the technical field of limb rehabilitation and relates to a limb rehabilitation training instrument for stroke patients. Background Art

[0002] A stroke may cause sudden rupture of blood vessels in the brain or blockage of blood vessels, which may prevent blood from flowing into the brain, leading to brain tissue damage. This may lead to a series of sequelae, such as sleep disorders, abnormal blood lipids, blood pressure, and blood sugar, and limb motor dysfunction. Therefore, rehabilitation training is often needed to improve the motor function of the limbs, reduce the patient's increased muscle tension, and improve the patient's quality of life. Limb rehabilitation training for stroke patients mainly includes flexion training of the upper limb joints and lower limb knee joints.

[0003] Among them, in the flexion training of the patient's knee joint, since severe stroke patients need to rest in bed, each time such patients undergo limb rehabilitation training, caregivers are required to fix or adjust the position of the instrument or equipment at the patient's knee joint, and then start the equipment to assist the patient in knee flexion. Severe patients require more frequent rehabilitation training, which requires more preparation work before each rehabilitation training and takes up more time of medical staff. In addition, the hard contact between conventional auxiliary instruments and the patient's knee joint affects the patient's comfort. Therefore, we propose a limb rehabilitation training instrument for stroke patients. Utility Model Content
