Abstract

Background: A simple and easy-to-use method for recording jaw muscle activity is important for minimising the need for specialised expertise in electrode placement, reducing the burden on the subject.

Objective: This study aimed to determine whether masseter muscle activity analysis by sound myography (SMG) combined with laser displacement-induced skin movement sensing (LDSMS) is comparable to surface electromyography (SEMG).

Methods: Eight healthy volunteers (21.0 ± 1.67 years) were included in the study. The measurement tasks consisted of clenching (CL), maximum jaw opening (MJO) and jaw closing and biting (JCB). Masseter muscle activity was recorded simultaneously using SMG, LDSMS and SEMG. We analysed the frequency amplitude spectrum using wavelet analysis and relationships between the signals from the three measurement methods (SMG, LDSMS and SEMG) using principal component analysis (PCA).

Results: The masseter muscle activity during jaw tasks analysed using SMG, LDSMS and SEMG was clearly defined. The peak of the integral time-frequency power (ITFP) (mV²/Hz) of the SMG was indicated by approximately CL, 9.8 ± 0.9, JCB, 10.5 ± 1.4 and MJO, 11.3 ± 1.4 Hz. The peaks of the LDSMS (CL, 4.2 ± 0.5, MJO, 4.2 ± 0.5 and JCB, 4.4 ± 0.6 Hz) and SEMG (CL, 54.7 ± 4.6 MJO, 102.1 ± 9.9 and JCB, 71.7 ± 9 Hz) were shown. PCA analysis revealed clusters of masseter muscle activity during jaw tasks obtained by the SMG, SEMG, and LDSMS devices.

Conclusion: The SMG with the LMSMS by wavelet analysis is a simple and easy-to-use method that can be used to detect jaw muscle activity issues.

用小波变换分析咀嚼正常任务运动中咬肌的声肌图。

背景：一种简单易用的记录颌骨肌肉活动的方法对于减少对电极放置专业知识的需求，减轻受试者的负担非常重要。目的：本研究旨在探讨声肌图（SMG）联合激光位移诱导皮肤运动传感（LDSMS）分析咬肌活动是否可与肌表电图（SEMG）相媲美。方法：8名健康志愿者（年龄21.0±1.67岁）参加研究。测量任务包括紧咬（CL）、最大颌张开（MJO）和颌合咬（JCB）。同时用SMG、LDSMS和SEMG记录咬肌活动。我们利用小波分析分析了三种测量方法（SMG、LDSMS和SEMG）的频率幅值谱，并利用主成分分析（PCA）分析了信号之间的关系。结果：用表面肌图、表面肌图和表面肌图分析了咬肌在下颚任务中的活动。SMG的积分时频功率（ITFP）（mV2/Hz）峰值分别为CL（9.8±0.9）、JCB（10.5±1.4）和MJO(11.3±1.4)Hz。LDSMS峰（CL, 4.2±0.5，MJO, 4.2±0.5和JCB， 4.4±0.6 Hz）和SEMG峰（CL, 54.7±4.6 MJO, 102.1±9.9和JCB， 71.7±9 Hz）显示。PCA分析揭示了SMG， SEMG和LDSMS设备在颌骨任务中获得的咬肌活动集群。结论：基于小波分析的下颌肌电信号与LMSMS相结合是一种简单易行的检测颌骨肌肉活动问题的方法。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
