AI Technical Summary

Technical Problem

In existing technologies, the diagnosis of temporomandibular joint disorders relies on subjective symptoms, making it difficult to distinguish between joint-related and muscle-related causes, resulting in insufficient diagnostic accuracy. Furthermore, the inability to simultaneously record multiple pieces of information leads to a lack of precision in treatment strategies.

Method used

By acquiring data from a miniature inertial measurement unit, surface electromyography sensor, and dual-channel contact microphone, six-degree-of-freedom motion information, three-dimensional motion trajectory curves, pain level information, joint clicking audio information, and muscle activity information of the temporomandibular joint are generated. These are then combined with a classification network for comprehensive analysis to determine the diagnostic results.

Benefits of technology

It improves the accuracy of determining the etiology of temporomandibular joint disorder, enables the fusion analysis of multiple types of information, and enhances the precision of diagnosis and the pertinence of treatment strategies.
