Embodiment 1

[0028] A fatigue assessment system based on electrical impedance, such as figure 1 shown, including the following steps:

[0029] Step 1. Place electrodes on the tired parts for muscle electrical impedance measurement;

[0030] Step 2. Massage and relax the tired part until you feel good;

[0031] Step 3. Place electrodes on the site and perform muscle electrical impedance measurement again;

[0032] Step 4, analyzing the electrical impedance data measured twice, and evaluating the relationship between the fatigue degree and the muscle electrical impedance.

Abstract

The invention relates to the technical field of test and evaluation, in particular to a fatigue degree evaluation system based on electrical impedance, which comprises the following steps: step 1, placing an electrode on a fatigue part to perform muscle electrical impedance measurement; step 2, massaging and relaxing the fatigue part until the feeling is good; 3, placing the electrode at the part,and carrying out the muscle electrical impedance measurement again; and 4, analyzing the electrical impedance data measured twice, and evaluating the relationship between the fatigue degree and the muscle electrical impedance. According to the invention, the muscle fatigue degree can be accurately evaluated, the targeted treatment can be performed, and the treatment accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of test evaluation, in particular to a fatigue degree evaluation system based on electrical impedance. Background technique [0002] Biomedical electrical impedance is a non-invasive technique for measuring the resistivity of human tissue that targets the resistivity distribution inside the human body. The human body is a large bioelectric conductor, and each tissue and organ has a certain impedance. When a certain current or voltage is added to the surface of the human body, different impedance distributions in the body will measure different voltages or currents on the body surface. Therefore, Muscle electrical impedance measurement technology actually measures the current induced on the body surface by injecting a known voltage into a specific part of the human body, or injecting a known current to measure the voltage induced on the body surface, using the measured current and voltage values, according to...
