Quantitative electromyographic response to therapy for myo-oral facial pain: a pilot study

In this pilot report, four of the five patients in the myofascial pain dysfunction group reported subjective improvement after 6 weeks of therapy, concomitant with a statistically significant decrease in integrated EMG Hz values in the clenched jaw position. Our results agree with those of other investigators who demonstrated a positive contribution by masticatory EMG data to confirm and quantify objectively the subjective symptoms.
