Ankle rehabilitation system capable of simulating walking based on VR

Abstract

The invention belongs to the technical field of medical rehabilitation, and discloses an ankle rehabilitation system capable of simulating walking based on VR. The system comprises a pressure detection module, a voice recognition module, a touch recognition module, a video monitoring module, a central control module, a network communication module, a server, a computer, a scene construction module, a human behavior recognition module, and a display module. The system provided by the invention is more advantageous for a user to actively carry out rehabilitation training of an ankle in a scene through a scene reconstruction module; can simulate the walking state of a patient through the visual feedback of the VR, feeds back and corrects a pathological walking mode, and forms a normal gait, thereby improving walking ability. Compared with the traditional walking rehabilitation training, the system has the effects of shortening the rehabilitation process, improving the rehabilitation efficiency and improving the rehabilitation effect. Through human behaviors, the system determines the moving significance area via the idea that a severe moving region provides more discriminating information in the behavior recognition, and assists the rehabilitation of the ankle.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation, in particular to an ankle rehabilitation system using VR to simulate walking. Background technique [0002] In patients with stroke, spinal cord, and peripheral nerve injuries, due to nervous system damage, decreased muscle strength, abnormal muscle tension, and joint contractures, etc., the ability to control motor movements will decline, resulting in abnormal gait and walking ability. In the early stage, walking training is carried out. If the rehabilitation method is improper, it is easy to form a pathological pattern, which is difficult in the later correction process. The visual feedback of VR can simulate the patient's walking state, and the feedback can correct the pathological walking pattern and form a normal gait, thereby improving the walking ability. Compared with the traditional walking rehabilitation training, it can shorten the rehabilitation process, improve the reh...

AI Technical Summary

Problems solved by technology

[0004] (1) The scene interaction effect in the existing VR ankle rehabilitation system for simulating walking is poor, which is not conducive to rehabilitation training; at the same time, the existing VR recognition technology has low efficiency in behavior recognition in complex scenes, and the effect is not good

[0005] (2) The current society is the era of rapid development of VR. The use of VR ankle rehabilitation system for simulating walking will generate a large amount of voice data. Although many useful information are hidden, most of them are garbage data. For these garbage data, it will increase the burden on the system and affect the treatment

[0006] (3) The work efficiency of the existing algorithm model is low; it cannot detect the scene correlation, scene richness and scene coherence of the ankle rehabilitation simulation scene image, and the reality reduction degree of the ankle rehabilitation is low.

[0007] (4) In the current pressure test instruments and equipment, the pressure data collection of the patient's ankle movement is not accurate enough, and the external pressure cannot be measured quickly and stably
