Evaluation of the function and activity of masticatory muscles using a self-developed wireless surface electromyog-raphy system
摘要
Abstract
Objective This study aimed to evaluate the repeatability and reliability of a self-developed domestic wireless surface electromyography(sEMG)system(Oralme-try)in assessing the activity of the temporalis and masseter muscles to provide theoretical support for its clinical applica-tion.Methods Twenty-two volunteers were recruited.Through multiple repeated measurements,the sEMG signals of bilateral anterior temporalis and masseter muscles during maximum voluntary clenching were collected using the self-de-veloped sEMG device,Oralmetry,and two commercial sEMG devices(Zebris and Teethan),filtered,screened,and stan-dardized.Seven sEMG indicators for assessing masticatory muscle function were calculated.The intraclass correlation co-efficient(ICC)was used to evaluate the repeatability of the measurements from the three sEMG devices,and statistical analysis was conducted to compare the consistency of the seven sEMG indicators obtained from the devices.Results Among the 22 participants,the ICC values of the repeated measurements from the three sEMG devices ranged from 0.88 to 0.99.The measurements of three sEMG indicators(antero-posterior coeffificient,percentage overlapping coeffifi-cient_MM,and percentage overlapping coeffificient_TA)obtained by Zebris were significantly different from those ob-tained by Oralmetry and Teethan(P＜0.05).No significant differences in the measurements of the seven sEMG indicators were found between Oralmetry and Teethan.Conclusion Oralmetry and the two commercial sEMG devices demonstrat-ed good repeatability in capturing sEMG indicators for evaluating masticatory muscle function.In particular,Oralmetry showed the highest ICC values.All three devices also exhibited good consistency in measuring sEMG indicators,and a high agreement was observed between the two wireless sEMG devices(Oralmetry and Teethan).These findings provide theoretical support for the clinical application of Oralmetry.关键词
