Feasibility of one-month home-based HRV monitoring in ASD: a case study using smart clothing technology

TL;DR

This study tested if smart clothing can be used to monitor heart rate variability at home for a month in a child with autism, finding it feasible even if it didn't predict next-day behavior issues.

Contribution

Demonstrates the feasibility of long-term home-based HRV monitoring in young children with ASD using smart clothing.

Findings

HRV monitoring was successfully conducted nightly for 25 days using smart clothing.

No significant differences in HRV or sleep time were found between nights preceding days with or without problem behaviors.

The study highlights the methodological transparency of using wearable ECG in home settings for children with ASD.

Abstract

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.

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.

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.

No significant differences in total sleep time or HRV indices were found between the two day types.

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.
