This study aimed to determine if supramalleolar orthosis (SMO) use improved activity level skill and participation levels in children with Down syndrome (DS) who have been walking for at least 1 year.
Twenty children with DS (aged 2–10 years) wore no orthoses for 4 weeks followed by SMOs for 4 weeks. At the initial visit, using goal attainment scaling (GAS), families determined two participation goals and expected outcomes. After both the no-orthoses and orthoses phases, goal attainment, Gross Motor Function Measure-Scale E, single-limb stance time, and shuttle run time were measured.
SMO use led to improvements in Gross Motor Function Measure-Scale E (P = 0.01) and GAS scores (P ≥ 0.001), as well as a time by condition interaction for shuttle run time (P = 0.049).
The use of SMOs led to improvements in activity level outcomes in family-selected participation goals.
