Halifax PrenaBelt Trial

"The PrenaBelt is a belt-like, positional therapy (PT) device designed specifically for pregnant women. While the PrenaBelt does not prevent the user from lying on her back or right side during sleep, it is expected to significantly decrease the amount of time she spends in these two positions via the mechanism of PT. PT is a simple, non-invasive, inexpensive, long-established, safe, and effective intervention for preventing people with positional-dependent snoring or obstructive sleep apnea from sleeping on their back - a position that exacerbates their condition.~The PrenaBelt is worn at the level of the waist. By virtue of its design and position on the user's body, the PrenaBelt affects subtle pressure points on the back and right side of the user when she lies on her back or right side, respectively, activating her body's natural mechanism to spontaneously reposition itself to relieve discomfort, thereby reducing the amount of time she remains on her back or right side."

The Sham PrenaBelt and PrenaBelt are the same device except the plastic balls are removed from the Sham PrenaBelt so it cannot provide pressure points.
