Abstract

The invention discloses a test method for detecting a muscle oxygen content and evaluating exoskeleton power assistance effect based on infrared spectroscopy. The method comprises the following steps:without wearing exoskeleton equipment, adjusting exercise load, and enabling active muscle to bear load exercise; carrying out statistical processing, carrying out polynomial function fitting on parameters, and approximately acquiring a function relation between different loads and corresponding muscle oxygen contents; wearing the exoskeleton equipment, adjusting the exercise load, enabling the active muscle to bear load exercise, and enabling the exoskeleton equipment to provide power assistance; substituting the corresponding average muscle oxygen content values under different loads into the function relation to obtain a motion load sensed under exoskeleton power assistance; calculating and recording the power assistance efficiency under each stage of load; carrying out polynomial function fitting approximation on the data to obtain a function relation between different loads and corresponding power assistance efficiencies; calculating definite integral of the function relation inan interval [0, 8], and dividing the definite integral by an interval length to obtain a power assistance efficiency mean value; and analyzing the power assistance efficiency mean value to evaluate the exoskeleton power assistance effect. The exoskeleton power assistance effect is scientifically evaluated.

Description

technical field [0001] The invention belongs to the technical field of ergonomics, and in particular relates to a test method for evaluating the power-assisted effect of an exoskeleton based on infrared spectrum detection of muscle oxygen content. Background technique [0002] According to relevant research, my country is currently in a period of severe aging, and there will be an increase of about 100,000 elderly people with severe movement disorders due to degeneration of body functions every year. In the medical field, especially in the rehabilitation treatment of patients with movement disorders, the rehabilitation therapy of exoskeleton assisting equipment is completely replacing the traditional artificial rehabilitation method, bringing more efficient and convenient rehabilitation therapy to patients, and at the same time reducing the burden of medical expenses. The work intensity of personnel has alleviated the relative shortage of medical resources to a certain exten...
