Correlations between jaw muscle hyperactivity and temporomandibular joint disorders and emotional stress are well known, but not well defined. Understanding and further analyzing these correlations using tools that were not heretofore available provides a means of quantifying the modulation of muscle recruitment in the jaw that results from emotional stimulation as opposed to normal muscle functionality. This paper compares the traditional techniques of amplitude and mean power frequency analysis with the continuous quantification of frequency content of a signal over time, known as multi-resolution wavelet analysis.
