Gait recognition-based functional electrical muscular stimulation walking aid

Abstract

A functional electrical muscle stimulation walking aid device based on gait recognition. The cloud server of the Internet of Things is wirelessly connected to n gait rehabilitation systems. The n gait rehabilitation systems have the same structure, and all include mobile phones or PCs, wireless routers, walking Gait acquisition system and functional neuromuscular electrical stimulator, the signal input end of the mobile phone or PC is connected to the signal output end of the gait acquisition system through a wireless router, and the control signal output end of the mobile phone or PC is connected to the functional neuromuscular through a wireless router The control signal input terminal of the electric stimulator, the signal output terminal of the mobile phone or PC is also wirelessly connected to the cloud server of the Internet of Things, and the output terminal of the functional neuromuscular electric stimulator is connected to the surface muscle stimulation electrode. The human body with the surface muscle stimulation electrode is different. The part is connected to the signal acquisition end of the gait acquisition system. The invention realizes closed-loop functional muscle electrical stimulation regulation with online real-time feedback, and achieves better walking aid and rehabilitation effects.

Description

technical field [0001] The invention relates to a gait rehabilitation device. In particular, it relates to a walking aid device for functional muscle electrical stimulation based on gait recognition. Background technique [0002] Gait is a complex and precise movement that can serve as an important external expression of human health performance. In the field of biomedicine, the correct identification and regulation of gait is of great significance for assisting patients with motor dysfunction to walk and performing targeted rehabilitation training. Medical research shows that gait analysis is very useful for the diagnosis of medical asynchronous morbidity, hemiplegia and other diseases, the etiology analysis of human motor system and nervous system diseases, the design of bone and joint prostheses and artificial limbs, and the reconstruction of walking function of paralyzed patients. It also provides important information for the prevention and rehabilitation of other dis...

Problems solved by technology

In 2010, J B Lee et al. published an article in the Journal of Sports Science and Medicine on the use of inertial sensors and infrared cameras to compare the measurement of gait parameters, which solved the problem of gait estimation only in traditional laboratories.
