Study Aims/Objectives
To test an alternative placement of a motion detector used to track sleep and to assess how children with Autism Spectrum Disorder (ASD) tolerate the device.

Methods - Sample, Procedure, Study Measures, Analysis
8 children (7 boys, 1 girl) with ASD between the ages of 6 and 10 years wore two motion detectors, one on the nondominant wrist and one on the nondominant shoulder, while they slept for 7 nights. Parents also kept a sleep diary over the course of the study. Total sleep time, time it took to fall asleep, sleep efficiency (ratio of sleep time to time in bed), and awakenings after falling asleep were calculated. 7-night averages of these measurements were compared between the wrist detector and the shoulder detector.

Results – Main Finding(s)
All children tolerated both placements well. The results from each device agreed the most for measurements of total sleep time, time spent falling asleep, and sleep efficiency. The lowest amount of agreement was for wake time after sleep.

Conclusion – Summary Statement
This pilot comparison study provides evidence that shoulder placement of motion detectors during sleep is feasible and well tolerated for children with ASD. Since many children with ASD do not tolerate the wrist placement well, it is important that these results of the shoulder placement be tested in a larger sample.
