sEMG and Vibration System Monitoring for Differential Diagnosis in Temporomandibular Joint Disorders

Abstract

The stomatognathic system represents an important element of human physiology, constituting a part of the digestive, respiratory, and sensory systems. One of the signs of temporomandibular joint disorders (TMD) can be the formation of vibroacoustic and electromyographic (sEMG) phenomena. The aim of the study was to evaluate the effectiveness of temporomandibular joint rehabilitation in patients suffering from locking of the temporomandibular joint (TMJ) articular disc by analysis of vibrations, sEMG registration of masseter muscles, and hypertension of masticatory muscles. In this paper, a new system for the diagnosis of TMD during rehabilitation is proposed, based on the use of vibration and sEMG signals. The operation of the system was illustrated in a case study, a 27-year-old woman with articular dysfunction of the TMJ. The first results of TMD diagnostics using the k-nearest neighbors method are also presented on a group of fifteen people (ten women and five men). Vibroacoustic registration of temporomandibular joints, sEMG registration of masseter muscles, and functional manual analysis of the TMJ were simultaneously assessed before employing splint therapy with stomatognathic physiotherapy. Analysis of vibrations with the monitoring of sEMG in dysfunctions of the TMJ can lead to improve differential diagnosis and can be an objective way of monitoring the rehabilitation process of TMD.

A Stretchable and Sweat-Adhesive 3D Graphene Eutectogel Electrode for EMG Monitoring

“…In recent years, wearable devices have made remarkable progress and have been widely used in different fields, such as human–computer interactions, healthcare, and drug delivery. − An epidermal electrode is a kind of wearable device and can collect electrophysiological signals, including electroencephalography (EEG), electrocardiography (ECG), electrooculography (EOG), and electromyography (EMG). − EMG is derived from electrical potential changes of muscle cells or muscle tissues during activity, which is used for fatigue assessment and relief, sports training, and prosthesis control. − However, epidermal electrodes no longer fit closely to skin after sweating or a period of use, which creates motion artifacts, reduces the signal-to-noise ratio (SNR), and makes it difficult to detect weak EMG. , In addition, human skin deforms with body movement. Dry electrodes do not adapt to the deformation and separate from skin, which cannot stably detect signals and causes discomfort. , Commercial gel electrodes usually reduce adhesion and conductivity after prolonged use due to water loss, which poses a challenge for long-term reusable electrodes. − Eutectic gels are a type of ionic gels, which have great adhesion and stretchability .…”
