Problems solved by technology

[0005] However, in the current test process for human swallowing, at most 4 channels are used to record relevant data, and the channels are few and out of sync, which cannot comprehensively and accurately reflect the coordination and consistency of relevant muscle groups.

Embodiment 1

[0045] Human swallowing is a complex process. Generally speaking, according to the physiology of swallowing, it can be divided into oral preparation phase, oral cavity phase, pharyngeal phase and esophageal phase, with a total of 25 pairs of muscles involved.

[0046] For this reason, the present invention hopes to monitor and record the whole process of human swallowing by synchronously monitoring multiple groups of swallowing muscles. The advantage of synchronizing multiple groups of muscles is that when the human body starts the swallowing process, it is the synergistic effect of multiple groups of muscles. Muscle synergy is monitored and measured.

[0047] The superficial muscle groups in the oropharyngeal phase mainly include: masseter muscle, orbicularis oris muscle, submental muscles (mylohyoid muscle, geniohyoid muscle, digastric muscle) and subhyoid muscle group (larynx muscles and thyrohyoid muscle).

[0048] Among them, in the current testing process for human swal...

Embodiment 2

[0059] The following details the first embodiment, wherein,

[0060] In step 1), the electrode placement of the following muscles / muscle groups is involved. The difference between the present invention and the prior art is that eight channels are used to obtain the surface electromyography synchronously, thereby forming two groups of masseter muscles, orbicularis oris muscles, Surface electromyography of the submental and subhyoid muscles.

[0061] Theoretically speaking, the surface electromyograms of the masseter, orbicularis oris, submental and subhyoid muscles should be basically consistent in the two groups. If they are not consistent, it can be preliminarily judged that there is a problem with the coordination of the muscle groups on both sides.

[0062] In an embodiment, the electrodes are patch electrodes for better testing and acquisition of data.

[0063] Specifically, in the present invention, 16 electrodes need to be placed, and every two electrodes are taken as a...

Abstract

The invention discloses a method for synchronously obtaining a surface electromyogram by eight channels. The method comprises the following steps of 1, an electrode putting step: putting four electrodes in positions of the left and right side masseter muscles, musculus orbicularis oris, chin muscle groups and hyoid muscle groups at the face part of the human body; 2, a test starting step: collecting electrode signals in different activity states on the basis of the electrodes; forming the surface electromyogram including two groups of masseter muscles, musculus orbicularis oris, chin muscle groups and hyoid muscle groups; 3, an evaluation step: concretely comprising the processes of obtaining data of swallowing time limit, the average vibration amplitude and maximum collection vibration amplitude in the surface electromyogram; judging whether the surface electromyograms of the two groups of masseter muscles, musculus orbicularis oris, chin muscle groups and hyoid muscle groups are identical or not; thus forming the relevant result of the swallowing function.

Description

technical field [0001] The invention belongs to the technical field of testing, and belongs to a technology for monitoring swallowing function by 8-channel synchronous surface electromyography. Background technique [0002] Surface electromyography (sEMG), also known as dynamic electromyography (DEMG), is a bioelectrical signal during neuromuscular system activity that is guided and recorded from the muscle surface through electrodes. There are different degrees of correlation between it and the active state and functional state of the muscle, so it can reflect the activity of neuromuscular to a certain extent. [0003] "Application progress of surface electromyography in the diagnosis and treatment of dysphagia" (http: / / wenku.baidu.com / view / d7efe1d5d4d8d15abf234e47.html?from=search) discloses a surface electromyography in the diagnosis and treatment of dysphagia application, which exposes the following: [0004] In the SEMG diagnostic procedure of swallowing function, con...
