Gait and balance rehabilitation training oriented single-rope suspension active weight reducing system

Abstract

The invention discloses a gait and balance rehabilitation training oriented single-rope suspension active weight reducing system which mainly comprises an overhead displacement unit, a vertical tension unit and a man-machine connection unit, wherein the overhead displacement unit comprises a body bracket, two transverse tracks, two longitudinal tracks and displacement driving mechanisms arranged below the two longitudinal tracks respectively; the vertical tension unit comprises a pair of slide rails, two moving plates, two compression springs, a pressure sensor, an electric cylinder, a rope winding motor, a winch and a deflection angle measuring device; and a lifting rope passes the winch driven by the rope winding motor, the pulley on one side of the electric cylinder, the pulley on the moving plate away from one side of the electric cylinder, the pulley at the top end of the pressure sensor and the lifting rope deflection angle measuring device, and is finally connected with the man-machine connection unit. In the novel virtual mass unloading lower-limb rehabilitation system disclosed by the invention, a good rehabilitation training environment is provided for patients suffering from mild and medium lower-limb nerve injury by a virtual mass removal method, and the system has remarkably high research values and broad application prospects.

Description

technical field [0001] The invention relates to a mass unloading technology in human rehabilitation training, which is generally used in the fields of robotics and rehabilitation medicine. Background technique [0002] Stroke and spinal cord injury are the main causes of lower limb motor dysfunction. Medical research shows that lower limb rehabilitation training can help patients with spinal cord injury recover the function of the nervous system. High-intensity and long-term rehabilitation training can be obtained through robot assistance, which is better than human assistance or self-training by patients. At present, the technologies that robots assist patients in lower limb rehabilitation mainly include: 1. Exoskeleton robot technology, which assists patients in rehabilitation exercises by wearing exoskeleton robots for patients. Most exoskeleton robots are also equipped with rope suspension systems. 2. The single-rope or multi-rope suspension system provides an upward we...

Problems solved by technology

2. Active weight reduction technology, the winding rope motor keeps the tension on the suspension rope constant through the winch. This method improves the defect that the passive weight reduction technology will increase the patient’s dynamic load, but it also fails to reduce the patient’s pain during exercise. Dynamic load, unable to achieve good virtual demassification effect

[0005] The current lower extremity rehabilitation robots are limited to the patient in a fixed position, and use equipment such as treadmills to perform walking training. This method can only allow the patient to perform simple front and rear gait training or squat movements at a fixed position, and cannot Help patients perform more rehabilitation actions, resulting in certain limitations
