Summary: | OBJECTIVE: In a device based on midsagittal jaw movements analysis,
we assessed a sleep-wake automatic detector as an objective method to measure sleep in
healthy adults by comparison with wrist actigraphy against polysomnography (PSG).
METHODS: Simultaneous and synchronized in-lab PSG, wrist actigraphy and jaw movements
were carried out in 38 healthy participants. Epoch by epoch analysis was realized to
assess the ability to sleep-wake distinction. Sleep parameters as measured by the three
devices were compared. This included three regularly reported parameters: total sleep
time, sleep onset latency, and wake after sleep onset. Also, two supplementary
parameters, wake during sleep period and latency time, were added to measure quiet
wakefulness state. RESULTS: The jaw movements showed sensitivity level equal to
actigraphy 96% and higher specificity level (64% and 48% respectively). The level of
agreement between the two devices was high (87%). The analysis of their disagreement by
discrepant resolution analysis used PSG as resolver revealed that jaw movements was
right (58.9%) more often than actigraphy (41%). In sleep parameters comparison, the
coefficient correlation of jaw movements was higher than actigraphy in all parameters.
Moreover, its ability to distinct sleep-wake state allowed for a more effective
estimation of the parameters that measured the quiet wakefulness state. CONCLUSIONS:
Midsagittal jaw movements analysis is a reliable method to measure sleep. In healthy
adults, this device proved to be superior to actigraphy in terms of estimation of all
sleep parameters and distinction of sleep-wake status. |
