A comparison of sleep detection by wrist actigraphy, behavioral response, and polysomnography
ML Blood, RL Sack, DC Percy, JC Pen - Sleep, 1997 - academic.oup.com
Two alternative methods for detecting sleep, wrist actigraphy (ACT) and behavioral
response monitoring (BRM), were compared to polysomnography (PSG). In the BRM
paradigm, a threshold intensity visual or auditory stimulus generated by a palm-top
computer was presented about once per minute, and subjects pressed a microswitch if the
stimulus was detected. A response within 5 seconds of the stimulus was scored as “wake”
and a failure to respond as “sleep.” Four males and four females underwent two nights of …
