The SleepGuard biofeedback headband provides a
gradual, gentle audio reminder to relax each time it senses that you
are clenching your teeth, allowing you to learn your way out of your
clenching habit while remaining asleep. Two sensor pads within the
headband let the electronic module monitor how hard your temporalis
muscles (part of the muscle group used in chewing) are clenching your
jaw. The electronic module not only provides biofeedback, it also tracks
how many times you clench and the total number of seconds you clench
each night, so you can see how much your clenching is reduced over time.
Short Daytime Training Sessions Allow You to Respond in Your Sleep
For the first three days, you train yourself briefly each day
to hear the biofeedback sound as a gentle reminder to relax. You train
yourself to relax your jaw as soon as you hear the sound. The sound
comes on slowly, so you can relax in your sleep without waking up.
During the first few days, you wear the
SleepGuard biofeedback headband at night with the biofeedback sound
turned off. This lets you measure your baseline clenching level. Each
morning, you can read out of the unit how many times you clenched and
the total number of seconds you clenched the night before.
The heart of the SleepGuard is a small electronic module that allows you to select a custom conditioning program for
you. SleepGuard'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 RelaxTone biofeedback signal
- Bite Level - how hard a bite it takes to trigger the biofeedback sound
The back of the device features a piezo tone
signal generator, which enables you to hear the biofeedback tone in both
ears through your forehead.
A comfortable fabric headband containing two conductive rubber
sensor pads like those found on a heart-rate monitor rests
against the skin. These sensor pads let the electronic
module measure how hard you are clenching. 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
RelaxTone is a patented innovation of SleepGuard. Because you
hear the tone in both ears from the sound touching your forehead, you
will be able to hear the tone much better than someone sleeping next to
you. 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 clenching while still asleep.
|ALERT - If you don't stop,the
tone volume gradually increases (to a level set by you). Your SCORE
increases one point, and the TIME function starts counting
|ALARM - After 5 seconds, the constant tone switches to an intermittent alarm, which continues until clenching or grinding
stops, or the unit shuts itself off in 30 seconds.
