Overview
The GrindAlert biofeedback headband is like having a multi-thousand dollar sleep lab electromyographic (EMG) microvolt meter and a computer packed into something almost as small as a watch. When the GrindAlert biofeedback headband senses the tiny electrical signals your jaw muscles give off when you clench, it emits a tone that assists you in training yourself out of clenching and grinding.
Electronic Module
The heart of the GrindAlert is a small electronic module that allows you to select a custom conditioning program for
you. GrindAlert's front control panel features MODE and SET buttons and a display showing:
| § |
Score - number of times you clenched since you last reset the unit |
| § |
Time - total duration of clenching since you last reset the unit |
| § |
Volume - volume of the SleepTone biofeedback signal |
§
|
Level - EMG threshold level: amount of jaw force necessary to trigger the tone |
The back of the device features a piezo tone signal generator, similar to alarms found on digital watches.
Headband
A comfortable fabric headband containing two conductive rubber contacts like those found on a heart-rate monitor rests
against the skin. These connect with a snap to the electronic module. An opening in the center of the
headband allows the tone generator to rest against the forehead. The headband is fully adjustable for all head
sizes.
SleepTone™
SleepTone is a patented innovation of GrindAlert, which uses a tone generator to transmit sound in a confidential
manner. This allows for lower volumes that won't wake your partner, and eliminates the need for an uncomfortable
earpiece that could interfere with your own sleep.
The tone comes in three levels:
| FAINT - A faint tone begins immediately upon clenching and continues for 2 seconds, giving you time to
stop. |
 |
| ALERT - If you don't stop, a louder tone sounds. The increased volume (set by you) is intended to make
you conscious of your activity. Your SCORE increases one point, and the TIME function starts counting
seconds. |
| ALARM - After 5 seconds, the constant tone switches to an intermittent alarm, which continues until clenching or grinding
stops. |
