CPM lower limb rehabilitation training method and system based on game and electromyographic signal

Abstract

The invention discloses a CPM lower limb rehabilitation training method and system based on a game and an electromyographic signal, relates to the field of biological-mechanical-electrical integrationtechnologies and aims to solve the problems that a patient feels boring during rehabilitation training and cannot move conveniently during training. The method mainly comprises the steps that the game is used as a medium, a biological human-machine interface is established to collect a surface electromyographic signal of a gesture action of the patient, and frequency-time domain analysis is performed to extract gesture characteristics; then, a principal component analysis method or a time sequence evaluation characteristic quality criterion is adopted to perform dimension reduction on the gesture characteristics; next, a gesture type corresponding to the gesture characteristics is recognized through an artificial neural network; and last, a CPM machine behavioral action corresponding to the gesture type of the patient is determined based on the corresponding relation between gesture types and CPM machine behavioral actions, and a CPM machine is controlled according to the CPM machinebehavioral action corresponding to the gesture type of the patient to achieve the purpose of training hurt lower limbs of the patient. Through the method and system, the effect of controlling the CPMmachine to train the hurt lower limbs of the patient through the game on upper limbs of the patient is achieved.

Description

technical field [0001] The invention relates to the technical field of biomechanical integration, in particular to a CPM lower limb rehabilitation training method and system based on games and electromyographic signals. Background technique [0002] The latest data show that by 2020, the population of the elderly is expected to reach 248 million. The threat of physical disability diseases is gradually emerging in society, and the frequent occurrence of natural disasters and traffic accidents has also caused a large number of patients with limb and joint damage. This type of patients needs to use equipment for training during rehabilitation. However, due to the weakening of the patient's own exercise ability and the boring training, it will be difficult for patients to carry out rehabilitation training and it is difficult to persist. Moreover, this type of patients needs the personal care of their family members, which seriously affects the normal life of the patients and eve...
