Initiative lower limb training system for synergy of healthy side and injured side and operation method of system

Abstract

The invention discloses an initiative lower limb training system for synergy of a healthy side and an injured side and an operation method of the system. Myoelectricity electrodes are distributed on the leg part on the healthy side and the leg part on the injured side, a sensor and a gyroscope are disposed on the leg part on the healthy side, and a computer is connected with the myoelectricity electrodes, the sensor and the gyroscope separately; an outer skeleton part is arranged on the leg part on the injured side and connected with the computer through a motor, and the computer is used for receiving signals input by the myoelectricity electrodes, the sensor and the gyroscope, adopting the driving motor for driving the outer skeleton part to move and adopting a man-machine interaction interface for achieving mirror neuron induction and visual feedback. By means of the system, the movement speed of the healthy side can be adjusted to adjust the movement of the injured side, and therefore adjustment of overall step speed is achieved; a walking process more similar to that of a healthy person is achieved, a patient can carry out real-time adjustment according to his / her conditions, and the subjective initiative of the patient is exerted to a greater extent. By adopting a pressure sensor and a previous time difference calibration mode, the stability and safety of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and in particular relates to an active lower limb training system with cooperation between the healthy side and the affected side and an operation method thereof. Background technique [0002] With the improvement of living standards and changes in fertility awareness, the problem of population aging is becoming more and more serious. Many elderly people are paralyzed due to stroke and other reasons, which makes life in their later years very inconvenient. Stroke paralyzed patients can stimulate brain plasticity through a large number of rehabilitation training, restore certain motor ability, realize self-care, improve quality of life, and return to society to the greatest extent. However, most of the current lower limb rehabilitation training requires therapists to detect patients in real time and artificially correct rehabilitation movements. This kind of rehabilitation...

Problems solved by technology

However, most of the current lower limb rehabilitation training requires therapists to detect patients in real time and artificially correct rehabilitation movements. This kind of rehabilitation training lacks quantitative indicators, and there will be inaccurate corrections during the artificial correction process, which seriously affects the rehabilitation training effect.

[0003] In recent years, with the development of robotics technology, various exoskeleton robots for lower limb rehabilitation have gradually emerged, which can effectively quantify various indicators. However, most of these rehabilitation systems are based on passive rehabilitation. Although there are also brain-computer-based interface or myoelectric signal lower limb rehabilitation exoskeleton robot, but these systems are semi-active combined with a single choice of action intention, and have not achieved complete active rehabilitation for patients with paralysis or severe motor function impairment. Nerve activation in the motor area, leading to poorer rehabilitation
