At-home sleep bruxism assessment developed

Researchers from the University of Eastern Finland have developed an easy-to-use electrode set to assess the severity of a patient's sleep bruxism in their own home. The technology was developed as part of a doctoral thesis project.¹ The diagnostic accuracy was compared to that of conventional polysomnography and other bioelectric measurements.

New polysomnography electrode set enables easy at-home assessment of sleep bruxism

Using the electrode set, nine out of ten at-home polysomnography recordings were of good quality, and the electrical impedance of the electrodes was at an acceptable level 90% of the time. Only one out of 101 recordings failed due to problems related to the electrode set. Supporting evidence was also found for a previous finding that some patients may present altered results on the first night due to the so-called first night effect, and sleep bruxism assessment may require more than one night of recording.
