Walking intention strengthening virtual induction method and system for people with lower limb dyskinesia

Abstract

The invention discloses a walking intention strengthening virtual induction method and system for a lower limb dyskinesia person, and the method comprises the steps: presetting a virtual simulation environment of rehabilitation training in a motion training process of a patient through combining a virtual reality technology and a biological electrical perception technology, enabling the patient to generate a walking intention under the induction of a virtual induction source to execute a preset walking task, respectively collecting displacement and walking speed of the patient and electromyographic signals of the lower limb surface in the walking process, performing fuzzy reasoning based on a membership function, judging the motion state of the patient, calculating the virtual and actual displacement difference between the virtual induction source and the actual motion of the patient, and carrying out a self-adaptive man-machine interaction control mode on the basis of real-time human body data of a patient, so the exercise interest of the patient and the active participation degree of training are improved, the man-machine interaction efficiency is enhanced, and the patient is helped to overcome bad results caused by various negative factors to a great extent.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation of patients with movement disorders of lower limbs, and relates to a virtual induction method and system for strengthening walking intention of persons with movement disorders of lower limbs. Background technique [0002] As the aging society continues to intensify, at the same time, accidental injuries or neuroskeletal muscular system diseases will lead to motor function impairment of the lower limbs, resulting in a large number of patients with motor dysfunction of the lower limbs. In addition to the necessary medical treatment for patients, walking training is essential for postoperative rehabilitation. In the current rehabilitation treatment, more and more rehabilitation physiotherapists advocate the rehabilitation model of "active exercise as the main and passive exercise as the supplement". , and more and more intelligent rehabilitation aids are used in sports training. In the proces...

Problems solved by technology

However, during the exercise rehabilitation training process, the patient will be accompanied by great pain, and is extremely prone to fatigue, so that the patient cannot produce a sustained strong exercise intention

[0003] In order to enhance patients’ interest in completing rehabilitation exercises and generate strong exercise intentions, the current method often used is to introduce a virtual reality system. The immersive three-dimensional virtual simulation environment will make patients feel as if they were there. However, the current virtual reality system only For information output, the interaction between the virtual scene and the patient is poor, unable to help the patient overcome various negative factors, and even accelerate the fatigue of the patient, making the induction effect not good
