Goldstein recently published a paper detailing a new algorithm, made by the researchers, that they validated for scoring sleep (because they couldn’t be sure consumer wearables were accurate).
Background: So far, sleep-tracking wearables have held promise, but not results, when it comes to research or to patient care. Companies don’t share how they score sleep, nor do they publish the kind of rigorous research a sleep medicine expert would want to review to determine if they can trust the sleep report given.
“We sent patients into the sleep laboratory for an overnight sleep study, wearing Apple watches, and used that data to develop our own algorithm to analyze acceleration and heart rate signal from the watch to estimate sleep,” senior author Cathy Goldstein, M.D., M.S., said.
