We are planning a study to assess the feasibility of aMultimodal Seizure Detection Instrument in patients with epilepsy. One of the outcome measures is sleep quality (total sleeping time, sleep architecture) in parents / loved ones. Several studies have reviewed consumer sleep tracking devices, which generally disappointing results regarding their accuracy (compared to Polysomnography).
Given innovation is going a fast pace, is their an affordable device with acceptable accuracy ?
There are so many sleep tracking devices on the market that it is arguable hard to say which is the best sleep tracking device because there is no clear robust evidence to come to such conclusion.
In one of our project, we used s+ by ResMed http://www.resmed.com/us/en/consumer/s-plus.html. It provides data on total sleeping time and sleep architecture.
None are validated (we reviewed the issues here, recently: www.ncbi.nlm.nih.gov/pmc/articles/PMC4640400/, and another group also recent review: www.ncbi.nlm.nih.gov/pmc/articles/PMC4661339/). The S+ has some advantages, but if there is a bed partner, it's unclear if it can distinguish the closer person for tracking. For those without insomnia or other primary sleep problems, it is possible that global measures (timing, total duration) might be useful in the way actigraphy is, but beyond that there is much uncertainty.
