Problems solved by technology

These are all analyzed from the perspective of muscle contraction to the changes induced by external force (exercise or electrical stimulation). However, after the external force is applied, there is no relevant research on the change of the basic energy of the myoelectricity itself when the muscle does not move.

Embodiment Construction

[0029] The method for studying muscle fatigue based on static myoelectricity after electrical stimulation of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0030] The method for researching muscle fatigue based on static myoelectricity after electric stimulation of the present invention comprises the following steps:

[0031] 1) Collect the static surface electromyographic signals of each subject separately, including:

[0032] (1) Select subjects, the number of subjects selected is more than 5, and the age difference is less than 3 years old. Arrange the time for each subject to accept the experiment; in this example, there were 7 subjects, aged between 23 and 25 years old, in good health, did not engage in strenuous exercise 24 hours before the experiment, and subjectively had no arm muscle fatigue symptom.

[0033] (2) Place surface EMG electrodes and stimulation electrodes on the subjects.

Abstract

A method for studying muscle fatigue on the basis of static myoelectricity after electrical stimulation includes respectively acquiring static surface myoelectric signals of each subject: selecting the subjects, arranging experimental periods, placing surface myoelectric electrodes and stimulating electrodes on the subjects, and acquiring the static surface myoelectric signals; and respectively analyzing power spectrums of the acquired static surface myoelectric signals: computing the acquired static surface myoelectric signals by a periodic diagram process to acquire the power spectrums, drawing frequency spectrograms according to the power spectrums, computing median frequencies and analyzing the median frequencies. The method has the advantages that change of the surface myoelectric signals after electrical stimulation can be represented, myoelectric response caused by electrical stimulation can be comprehensively evaluated in a frequency domain, an experimental basis is provided for follow-up study, accordingly, an idea is provided for technical standards for evaluating effects of electrical stimulation on human bodies, and development of electrical stimulation is promoted.

Description

technical field [0001] The invention relates to a method for evaluating muscle fatigue caused by electrical stimulation. In particular, it relates to a method for studying muscle fatigue based on static myoelectricity after electrical stimulation. Background technique [0002] As a safe and effective rehabilitation therapy, electrical stimulation has been gradually applied in the clinical treatment of various neuromuscular diseases, and its research and development has attracted the attention of various countries. However, the widespread application of electrical stimulation is also limited by a factor, which is the muscle fatigue it induces. Muscle fatigue usually refers to the temporary decline of the system's maximum working ability or maximum contraction ability, which directly affects the effect of stimulation and reduces the contraction response of muscles. The measurement and real-time monitoring of muscle fatigue is an important issue in the clinical treatment of e...
