Evaluation Study Reveals SLEEPTRACKER(R) Nearly As Effective In Gathering Specific Sleep Data As Advanced Sleep Lab Equipment
The evaluation study was independently conducted by Douglas W. Puryear, MD, FCCP, D. ABSM, director of Sleep Disorders Centers of Pulmonary Associates in Midlothian, VA. The primary purpose of the study was to compare SLEEPTRACKER with advanced sleep laboratory equipment in the proper detection of movement events while sleeping.
"The popularity of SLEEPTRACKER had led many sleep researchers to inquire about its ability to monitor sleep events based on movement," said Lee Loree, developer of SLEEPTRACKER. "This new evaluation study only furthers what we already knew about the product - that it is effective in measuring the movements associated with a light sleep stage, helping thousands of people across the globe wake up feeling more refreshed."
Using a small accelerometer to measure certain types of lateral motion that correlate to lighter stages of sleep, SLEEPTRACKER continuously monitors signals from the body that indicate whether the person is asleep or awake. It uses those times of motion to give the user a picture of how many restless or light sleep periods they have throughout the night. The more recorded events, the more restless (i.e. worse) the night of sleep. The device also uses those recorded moments to detect lighter stages of sleep within an alarm window to wake the user at the optimal time in the morning.
A total of 18 subjects were used to collect sleep data during one night each, during which a battery of measurements was recorded in the lab on each subject. Movements were monitored and recorded by both SLEEPTRACKER and the lab equipment. The sleep data was then summarized to compare event detection between SLEEPTRACKER and the lab equipment - considered the "gold standard" in the study.
"I was extremely interested to test SLEEPTRACKER after hearing about the popularity of the product and how many devices had been sold worldwide," said Douglas W. Puryear, MD. "After compiling the results of my evaluation study, I can say with confidence that SLEEPTRACKER's performance in detecting events is excellent, as compared to state-of-the-art sleep laboratory equipment used in my center. This is the only non-medical device I've ever seen that can provide such sleep insight to consumers."
The evaluation study concluded that, of a total of 203 total events detected by either SLEEPTRACKER or the sleep equipment, SLEEPTRACKER correctly recorded 176 true events, missed only 16 true events and incorrectly reported 11 non-events. Therefore, for every 6.52 correct positive detections, SLEEPTRACKER makes only one mistake. In terms of positive detections only, SLEEPTRACKER correctly detects and records 91.67 percent of 192 true events (a false positive rate of only 8.33 percent.)
