| Abstract: | The electromyographic activity (EMG) of the jaw musculature is of interest in relation to the diagnosis of certain facial pain conditions in which muscle hyperactivity has been implicated. The mean power frequency of the EMG is of special relevance; it is known to be sensitive to experimentally induced fatigue which has been studied as a pathophysiological model of the temporomandibular joint pain dysfunction syndrome. An inexpensive microcomputer-based system is described which is suitable for performing spectral analysis in laboratory experiments and in the clinical situation. |
