Play therapy plus a wearable gamified heart-rate biofeedback for children with autism

Play Therapy With Gamified Biofeedback in Children With Autism Spectrum Disorder: A Randomized Clinical Trial

Not applicable Interventional Faculdade de Ciências Médicas de Minas Gerais · NCT07322640

This project tests whether adding a wearable, game-like heart-rate biofeedback armband to weekly play therapy helps children aged 6–10 with ASD level 1 manage emotions and improve social skills compared with play therapy alone.

What this trial studies

This single-center, randomized, parallel-group trial will enroll 68 children aged 6–10 with DSM-5 ASD level 1 and randomly assign them to eight weekly 50-minute sessions of either standard child-centered play therapy or play therapy combined with real-time gamified biofeedback delivered via a comfortable armband. The biofeedback arm translates heart-rate calming into game rewards to encourage self-regulation in a playful context, while the control arm receives deactivated biofeedback or standard play therapy. Parents and teachers complete brief questionnaires before and after the intervention, and outcome assessors are blinded to group assignment. The trial is pragmatic and designed to fit routine outpatient care at the Faculdade de Ciências Médicas de Minas Gerais in Belo Horizonte, Brazil.

Who should consider this trial

Good fit: Children aged 6–10 with a formal DSM-5 diagnosis of ASD level 1, able to interact with tablet-based games and wear a comfortable armband, whose parents provide consent and who do not have recent medication changes, are ideal candidates.

Not a fit: Children with severe intellectual disability, uncontrolled epilepsy, severe psychiatric comorbidities, unstable systemic medical conditions, or contraindications to biofeedback are unlikely to benefit or be eligible for this intervention.

Why it matters

Potential benefit: If successful, the approach could give children an engaging way to learn to calm physiological arousal, leading to better emotional regulation, reduced anxiety, and improved social participation.

How similar studies have performed: Heart-rate variability biofeedback and other biofeedback approaches have shown promise for emotional regulation in some populations and small ASD samples, but gamified wearable biofeedback in children with ASD is relatively novel and not yet widely tested.
