The accuracy of the THIM wearable device for estimating sleep onset latency.

ABSTRACT:

Study objectives

THIM is a wearable device designed to accurately estimate sleep onset. This article presents 2 studies that tested the original (study 1) and a refined (study 2) THIM algorithm against polysomnography (PSG) for estimating sleep onset latency.

Methods

Twelve (study 1) and 20 (study 2) individuals slept in the laboratory on 2 nights where participants underwent THIM-administered sleep onset trials with simultaneous PSG recording. Participants attempted to fall asleep while using THIM, which woke them once it determined sleep onset.

Results

In study 1, there was no significant difference between PSG (mean = 1.94 minutes, SD = 1.32) and THIM sleep onset latency (mean = 2.05 minutes, SD = 1.38) on the first or second night (P > .07). There were moderate co
