AI Technical Summary

Problems solved by technology

The existing method of drawing MEP topographic maps uses surface patch electrodes, which not only cannot detect the deep swallowing muscles, but also the measured MEP is not accurate due to the interference of the skin surface

Abstract

The invention provides a drawing method for an MEP topographic map of a pharyngeal motor cortex area, and further relates to a method for an MEP location map of the pharyngeal motor cortex area. According to the method, an electrode in the pharyngeal cavity is utilized to be inserted into the pharynx of the human body through the nasal cavity and the oral cavity to achieve the effect of accuratelyrecording electromyographic signals of the deep muscle of the pharynx, a positioning cap provided with multiple lattices of smaller sizes is utilized to cover the corresponding brain area to finallyachieve the effect of accurately drawing the MEP topographic map of the pharyngeal motor cortex area, and the drawing method is utilized to measure and draw multiple subjects to finally obtain the MEPlocation map of the pharyngeal motor cortex area of healthy people.

Description

technical field [0001] The invention relates to a method for drawing a MEP topographic map, in particular to a method for drawing a MEP topographic map of a pharyngeal motor cortex area. Background technique [0002] Motor evoked potential (MEP) is a compound muscle action potential recorded on corresponding muscles by transcranial magnetic stimulation of motor cells in the cerebral cortex, spinal cord, and peripheral nerve motor pathways. This technique was established by Barker et al. in 1985 and has been widely used clinically this year, providing an objective basis for the determination of central conduction time of motor pathways. Existing methods for drawing MEP topographic maps are mainly hand muscles such as thumb abductors, etc. This method uses surface patch electrodes to record muscle electromyographic signals and the drawing methods are varied and lack uniform standards. [0003] The pharyngeal muscle group is an important muscle in the successful swallowing act...
