The Power Down Pilot Study: A Novel Bedtime Manipulation Protocol

The Power Down is a bedtime manipulation protocol targeting elevated arousal level at bedtime due to a hypothesized effect of sensory over-responsivity (a common experience for autistic children). The Power Down incorporates sensory-based tools (gentle tactile pressure and auditory cues) to support nervous system regulation prior to attempting sleep onset. Participants (caregivers and their child) will be educated in the Power Down protocol and data collection methods for the 2 week intervention trial. Caregivers will lead a nightly gentle massage with guided relaxation script just prior to the child trying to fall asleep. The child will also wear a watch-like activity monitor (ActiGraph GT9x) for the 2 week period throughout the day and night to measure changes in sleep and activity patterns. Caregivers will complete daily diary questions in the morning and evening reporting their child's emotions and sleep timing.
