Abstract

The invention discloses a muscle fatigue detection method combining surface myoelectricity and myocrismus with a near infrared spectrum, and relates to the field of human motionfunction detection andevaluation. Constant length static contraction is adopted, and muscle fatigue is made; surface myoelectricity, myocrismus and a near infrared spectrum signal in the muscle activity are recorded synchronously; corresponding fatigue parameters are built in the five aspects of muscle fiber action potential collection characteristics, action potential conductivity, muscle fiber low-frequency vibrationcharacteristics, hemodynamic characteristics and blood oxygen metabolism, and a muscle fatigue mechanism is analyzed and evaluated. Accordingly, the muscle fatigue is detected and analyzed in an noninvasive mode; by measuring the myoelectricity and myocrismus and the near infrared signal simultaneously, more reliable muscle fatigue information is obtained; the muscle fatigue is comprehensively detected in the five aspects of the muscle fiber action potential collection characteristics, the action potential conductivity, the muscle fiber low-frequency vibration characteristics, the hemodynamiccharacteristics and the blood oxygen metabolism, and cognition on the fatigue mechanism is deepened.

Description

technical field [0001] The invention relates to the field of human body motion function detection and evaluation, in particular to a muscle fatigue detection method combining surface myoelectric myotone and near-infrared spectrum. Background technique [0002] Muscle fatigue is a manifestation of the state of human motor function, which is defined as the decline in the ability of muscles to perform work under the condition of repeated work. Studying the law of muscle fatigue can deepen the understanding of fatigue mechanism and promote the development of human motor function assessment and rehabilitation medical level. However, current technical means to detect muscle fatigue are extremely limited, such as invasive methods such as blood tests, and the understanding of the mechanism of muscle fatigue is still extremely insufficient. Muscle fatigue is also affected by psychological factors and the working environment, but the most fundamental reason is the change of oxygen me...
