# 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.

## Key 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.
