A new 3-year project led by scientists in Washington State University’s Sleep and Performance Research Center may soon bring relief to those who toss and turn. In collaboration with the University of Washington, the researchers will test the effectiveness of a low-cost sleep measurement technology with built-in sleep coaching functionality in individuals with chronic insomnia. Insomnia is considered chronic if disrupted sleep occurs at least 3 nights a week for more than 3 months.
Known as the S+ by ResMed, the technology is a noncontact sleep sensor designed to sit on a sleeper’s night stand, where it measures timing, quantity, and quality of sleep. An integrated function called S+ Mentor uses an app on a connected smartphone or tablet to provide users with sleep scores and charts, along with individualized suggestions on how sleep may be improved. Previous studies have validated its use for tracking sleep in healthy sleepers and people with obstructive sleep apnea, but scientists have not yet tested the technology in individuals with insomnia.
“We will investigate to what extent this technology can accurately measure insomniacs’ sleep patterns over days and weeks and provide tailored improvements in their sleep,” says Devon Grant, PhD, LMHC, principal investigator of the study and a postdoctoral researcher in the Elson S. Floyd College of Medicine, in a release. “This could help expand cost-effective therapy options available to this undertreated population.”
Measuring, Improving Sleep
Grant says the current standard for treatment of chronic insomnia is cognitive behavioral therapy for insomnia (CBT-I). While working as a therapist at a Spokane-based sleep clinic, she created the area’s only such program and ran it for more than 10 years. While CBT-I is considered to be effective and can provide long-lasting benefits, participation has been limited mostly by high costs and a lack of qualified providers. A recently developed online version of CBT-I has resolved some of these issues while showing comparable results, but still may not be right for everyone, Grant says.
For their study, the research team will recruit 90 adults with chronic insomnia in the Spokane and Seattle areas, along with 30 healthy sleepers who will serve as controls. Participants will be monitored for two months in their home environment. Those with insomnia will be randomly assigned to one of three groups—one group will only have their sleep monitored by the new technology; the other two are intervention groups in which sleep monitoring will be combined with either participation in an online CBT-I program or sleep coaching through the technology’s mentoring feature.
Data from the study will be analyzed to determine whether the new technology measures participants’ sleep accurately. In addition, the researchers will compare treatment outcomes between the two intervention groups to see whether the technology’s coaching functionality is at least as effective in treating chronic insomnia as online CBT-I.
New Research Direction
“This study takes our research portfolio in a novel, clinical direction, helping to improve the performance, safety, and well-being of individuals whose waking alertness is adversely affected by a highly prevalent sleep disorder,” says Hans Van Dongen, director of the WSU Sleep and Performance Research Center and a professor in the Elson S. Floyd College of Medicine.
Nice to see ResMed taken a leading edge on Insomnia. Question, Will this be a cash and Carrie item or are you work with insurances.
A distally displaced mandible reduces the posterior airway AND it pinches nerves in the jaw joint space.
These pinched nerves excite the nervous system and make sleep difficult.
Many of my patients experience a significant reduction of their insomnia while wearing an oral appliance designed to treat OSA. This supports the mandible more forward, relieving the pinched nerves. This is made for the insomnia patient with or without an OSA diagnosis.
It would be interesting to studying insomnia patients with this instrument with and without an oral appliance.
