Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a lower limb rehabilitation training device for patients with cerebral infarction. Background Art

[0002] The rehabilitation treatment of lower limb dysfunction is a long-term treatment process. Cerebral infarction patients are different from other trauma patients in that they have a series of abnormal manifestations and dysfunctions due to brain damage itself, as well as abnormal movement patterns due to the loss of part of the brain control of the lower central spinal cord. This not only affects the recovery process of motor function, but also creates great obstacles to the recovery of motor ability and normal posture, such as hemiplegia, which makes them have lower or basically no control over their limbs than trauma patients and require external assistance. As the initial stage of lower limb rehabilitation training, patients need a lot of external control to assist them in making rehabilitation postures or performing rehabilitation exercises. The human body has many joints in the lower limbs. The common lower limb rehabilitation training device for patients with cerebral infarction has a relatively simple structure and can usually only perform repetitive and single-part rehabilitation movements, which greatly reduces the effect of rehabilitation training. In addition, the replacement of training parts requires the help of medical staff or patients' families to adjust, which seriously increases the occupation of human resources and lacks practicality. Therefore, we propose a lower limb rehabilitation training device for patients with cerebral infarction. Summary of the invention
