A new approach in diagnosing temporomandibular joint dysfunction

In today’s society, temporomandibular joint disorders are a growing health problem and include a group of complaints related to masticatory muscle pain, headaches, abnormalities of mandibular movements, and pain and vibroacoustic phenomena generated in the joints during mandibular movements. Classical diagnosis of temporomandibular joint dysfunction involves, among other things, imaging evaluation – X-ray, MRI, CT scans performed by radiology specialists. The Department of Mechanics and Vibroacoustics, in cooperation with the Institute of Physiotrerpaia of the Collegium Medicum of the Jagiellonian University in Krakow, is conducting research on objective and non-invasive assessment of temporomandibular joint function using the technique of surface electromyography (sEMG) and analysis of vibrations generated during mandibular movement. A measurement system consisting of a hardware module for the acquisition of vibration acceleration and sEMG signals, along with proprietary software for the analysis and evaluation of these signals in correlation with video images recorded within the mandible during the performance of a protocol-determined test, has been developed for the implementation of the study. The study is being conducted starting in 2019 on a group of patients undergoing treatment and rehabilitation.
