Embodiment Construction
[0028] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0029] Surface electromyography is a method for evaluating muscle function by recording the electrical activity of the muscle on the skin surface, that is, the single action potential sequence generated by the measured muscle during exercise is guided, amplified and recorded by surface electrodes, thereby forming a one-dimensional Voltage time series signal. Due to its advantages of non-invasiveness, integrity, and multi-channel measurement, it is currently mainly used in rehabilitation medicine, sports medicine, sports science, etc., and can also be used in pattern recognition, ergonomics and other fields. Surface electromyography can not only measure muscle activity in a static state, but also dynamically monitor electrophysiological changes during muscle contraction and quantitatively analyze muscle functio...

The invention discloses a surface electromyogram synchronous audio signal acquisition method, comprising the following steps: (1) when a subject is at rest, moving, pronouncing, short sentences and reading, collecting trapezius muscle and sternocleidomastoid muscle , the surface EMG signal of the suprahyoid muscle group, the subhyoid muscle group, and the cricothyroid muscle, and the voice signal of the subject is collected synchronously; (2) the surface EMG signal and voice obtained in step (1) Signals were comprehensively analyzed to analyze the relationship between articulation and the timing and amplitude of muscle recruitment. Using the above-mentioned surface EMG synchronous audio signal acquisition method, the muscle recruitment and audio signals of subjects in different states such as rest, activity, pronunciation, short sentences and reading can be synchronously collected, so as to detect in a non-invasive way. Whether there is functional dysphonia in the external laryngeal muscles. The invention also discloses a device for realizing the above-mentioned surface electromyography synchronous audio signal acquisition method.
Description
technical field [0001] The invention relates to a surface electromyography synchronous audio signal acquisition method, and also relates to a surface electromyography synchronous audio signal acquisition device. Background technique [0002] In 1944, Weddell et al. first applied electromyography to the examination of laryngeal muscles. By studying the bioelectrical activities of the laryngeal muscles during pronunciation, breathing and swallowing, they could judge the functional state of the neuromuscular system, and provide a corresponding scientific basis for clinical diagnosis. Clinically applied EMG examination mostly uses needle electrodes (that is, where the electrodes are inserted into the muscle belly) to detect EMG signals. The advantages are accurate identification of signals, little interference from surrounding signals, and accurate detection positions. characteristics, the clinical application has been limited. [0003] With the wide application of needle EMG, ...
