Is this trial a fit for you?

Likely a good fit

Ideal candidates are infants under 24 months with a confirmed diagnosis of Trisomy 21 who can sit without support and are not yet walking independently.

Probably not a fit

Patients with mosaic or translocation Down syndrome or those with severe uncontrolled medical issues may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This project aims to enhance mobility in infants with Down syndrome by using body weight supported harness systems. The study will involve home visits and virtual sessions where infants and caregivers will be observed during playtime, both with and without the harness. Data will be collected on language and locomotor development, as well as the feasibility and acceptability of the harness system. The goal is to gather preliminary data to support a larger clinical trial focused on improving mobility and social interaction in these infants.

Why it matters

Potential benefit: If successful, this intervention could significantly improve mobility and developmental outcomes for infants with Down syndrome.

How similar studies have gone: While this approach is innovative, similar interventions targeting mobility in infants with developmental delays have shown promise, suggesting potential for success.
