Destribution of masticatory electromyograph parameters during the tapping movement in young adults

Abstract

The muscle activity voltage and rhythm pattern by the masticatory electromyograph measurement have been reported numerously as 1 piece of the function evaluation law in the stomatognathic function. However, as for these the object the actual condition is not clear with 3〜30 subjects. I studied of masticatory electromyographs during tapping movements, and ana-lyzed the distribution of parameters in young adults of 22 to 23 years of age. The frequency distribution in the histogram was expressed with the relative ratio, to com-pare and examine the distribution of each 114 parameters. Also stomatognathic function is in-vestigated by the questionnaire and divide into the unsymtom group and symptom group and did the test for equal with SPSS. Cycle time understood that is receiving the influence of interval from duration. Duration and interval adjusting it mutually for the acquisition of cycle time rhythm in, CV of each parameter it became with clear to be being. Each parameter of masticatory electromyograph of tapping movement showed the distribu-tion that has a characteristic. It was difficult nature, to do the normal value that the individual was limited and was have from the distribution of each parameter that was displayed detection. However, it was consid-ered to be useful for the research of the objective evaluation of jaw mouth function condition, that distribution condition was diferent in the particular parameter of masticatory electro-myograph, with symptom group.
