Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation devices, and in particular relates to a lower limb non-weight-bearing exercise rehabilitation device. Background Art

[0002] Diabetic patients often have neuropathy, vascular disease and other problems in their lower limbs, leading to symptoms such as lower limb muscle atrophy, joint stiffness, pain, and paresthesia. These symptoms can affect patients' gait, balance, and daily living abilities, such as walking, standing, and going up and down stairs. Therefore, lower limb rehabilitation training is very important for diabetic patients. It can help them improve lower limb function, relieve pain, and improve quality of life. It can also help improve patients' blood sugar control, circulatory system function, and nervous system function. Patients' lower limb rehabilitation movements are generally based on lower limb flexion and extension movements. For those whose physical skills are not sufficient to support autonomous training, they need to use equipment for passive training. However, existing equipment of this type can only help patients complete training movements, and there is a problem that the training range and intensity cannot be automatically and accurately controlled according to the actual situation of the patient.
