Why the study?
Sleep disturbances and autonomic dysregulation are common in autism spectrum disorder, but few studies have evaluated long-term nocturnal heart rate variability monitoring in home settings.
Does nocturnal HRV predict next-day problem behaviors in a preschooler with ASD?
Does nocturnal HRV predict next-day problem behaviors in a preschooler with ASD?
While one-month home-based nocturnal HRV monitoring using smart clothing is feasible in a preschooler with ASD, HRV indices did not significantly predict next-day problem behaviors in this single case.
Background: Sleep disturbances and autonomic dysregulation are common in autism spectrum disorder (ASD), yet few studies have examined long-term nocturnal heart rate variability (HRV) in home settings. Objective: This study evaluated the feasibility of one-month home-based HRV monitoring using smart clothing in a preschooler with ASD, and explored whether nocturnal HRV predicts next-day problem behaviors. Methods: HRV was recorded nightly for 25 valid days using a garment-type wearable ECG. Problem behaviors were reported daily by caregivers. HRV indices were compared between nights preceding days with and without problem behaviors using Wilcoxon signed-rank tests. Results: No significant differences in total sleep time or HRV indices were found between the two day types. Conclusion: Although HRV did not predict next-day behavior, the study demonstrates the feasibility and methodological transparency of long-term home-based physiological monitoring in young children with ASD.
