Abstract:
1. An apparatus for detecting bruxism and providing feedback to a user, said apparatus comprising: a sensor system operable to measure the muscular activity of a user's jaw associated with a level of biting force and generate a signal corresponding thereto; a signal processor which is in communication with said sensor system and is operable to receive said signal as a function of time, wherein said signal processor is configured such that the signal received from the sensor system as a function of time is divided into windows of a predefined time interval and configured such that a calculation of the area under the curve of the muscular activity vs. time is provided for each time window to yield the total biting power for each time window and calculate a level of muscular activity and integrate said level vs. time, so as to provide a processed signal, and a feedback signal generator which is in communication with said signal processor, said feedback signal generator being operable to receive said processed signal from said sensor system and generate a feedback signal, and direct said feedback signal to said user if the level of muscular activity measured by said sensor system exceeds a predefined threshold level of muscular activity for a predefined period of time.
