Difference between Right and Left Facial Surface Electromyography in Healthy People

Introduction. The study was to see whether there were differences in values of facial surface electromyography in subjects of good heath by muscles, age, and sex. Methods. It draws ratio between lower value and higher value (R-LV/HV) and asymmetry index (AI), based on root mean square (RMS) from mea...

Description
Summary:Introduction. The study was to see whether there were differences in values of facial surface electromyography in subjects of good heath by muscles, age, and sex. Methods. It draws ratio between lower value and higher value (R-LV/HV) and asymmetry index (AI), based on root mean square (RMS) from measurement of facial surface electromyography (sEMG) in 154 people of healthy people (male:female = 70:84) aging between more than 20 and less than 70. Results. For R-LV/HV, it averages 81.70±14.60% on frontalis muscle, 73.74±19.12% on zygomaticus muscle, and 79.72±14.77% on orbicularis oris muscle. With analysis of the AI average was 10.87±10.14% on frontalis muscle, 16.71±14.79% on zygomaticus muscle, and 12.10±10.05% on orbicularis oris muscle. Both values were statistically significant in three parts of muscles as shown. Both of R-LV/HV and AI show no statistically significant difference on age and sex (p>0.05). Conclusions. It could provide basic data for the future diagnosis of facial nerve palsy patients by measuring facial sEMG values for healthy people.
