Aims:
To explore trends in gross motor skill acquisition associated with a parent‑implemented Hip Helpers® home program in two matched pairs of infants with Down syndrome (DS).
Methods:
In this prospective exploratory matched‑pair case series, two 6-month-old (Child A1 and Child A2) and two 9-month-old (Child B1 and B2) children with Trisomy 21 DS participated in a Hip Helpers® home program (two daily 30-minute sessions during active play). Pairs had similar motor abilities and continued usual therapies. Use of Hip Helpers® for child A2 and B2 was discontinued when the children could pull themselves to a standing position. Testing using the Gross Motor Function Measure (GMFM-88) occurred monthly until each participant was able to take three independent steps.
Results:
GMFM-88 change scores were variable across pairs, with the largest gains in Sitting (Dimension B). Crawling began later in garment users, suggesting a potential tradeoff. No adverse events were reported.
Conclusions:
Neither child who participated in the Hip Helpers® home program showed a faster acquisition of gross motor skills than is predicted for children with DS who do not use the garment. Feasibility was suggested; acceptability was not measured. Larger studies with objective adherence and standardized feasibility/acceptability tools are needed.
