In addition to the Holistic Technologies clinical trial, Weinstein points to brain scan research done by Dr. Nouchine Hadjikhani on chronic migraine sufferers at Massachusetts General Hospital in 2007, which showed that the brain structure of chronic migraine sufferers differs from that of other people in the region of the somatosensory cortex that receives sensation signals from the head and face (including the roots of the teeth). “When someone habitually clenches her teeth in her sleep”, says Weinstein, “the clenching force is often so hard that it would be painful if she were awake. For people with migraine-sensitive brains, the nerve signals streaming into the somatosensory cortex from nighttime teeth clenching set up the conditions that allow the cascade of neurochemical events that make up a migraine, so for many people, stopping the clenching prevents the migraine.”
The biofeedback headband may also be used in silent mode (diagnostic mode), which allows quantifying the severity of a person’s nighttime clenching habit, and allows clinicians and consumers to measure whether a particular treatment or diet change increases or decreases a person’s nighttime clenching. Because the free trial period for the SleepGuard biofeedback headband is 21 days, there is plenty of time for someone to figure out whether nighttime clenching is a pr
