Purpose: Ankle strength plays a crucial role in balance and functional movement. Previous research has displayed that children with Down syndrome (Ds) may present challenges in these areas due to low neuromuscular function and overall joint laxity. The aim of this study was to analyze the effects of a 4 week ankle strengthening program on balance and functional movement in 3 individuals (ages 5-10) with Ds. Methods: 3 female subjects (x̄ age 8.0±2.64SD, HT 43.0±5.2in, WT 67.7±25.6lbs) were clinically diagnosed with Ds. Subjects attended a 6 week program, including: 1 pre-test session collecting anthropometrics, Functional Movement Screening (FMS) scores and Modified Clinical Test of Sensory Interaction on Balance (m-CTSIB) scores; 4 1-hour ankle strengthening sessions once a week; and 1 post-testing session for FMS and m-CTSIB scores. Prior to the FMS, subjects were given scripted explanations and demonstrations of movements and familiarized with protocol for the m-CTSIB. The 4 week strengthening sessions incorporated 11 ankle strengthening activities and 1 take home activity per week. Special adaptations and parent support were used to encourage participation during activities. Results: Pre-test (x̄=2.7, SD=0.5), Post-test (x̄=2.1, SD=0.4) for m-CTSIB scores. Pre-test (x̄=18, SD=5.2), posttest (x̄=18.5, SD=6.1) for FMS scores. No statistical analysis was completed due to small sample size.

Conclusion: Researchers observed an improved ability to perform ankle movement activities and a trend towards improvement in m-CTSIB testing. With a larger sample of the population with Ds, future research may confirm the benefits of ankle strengthening protocols as it applies to lower extremity function, balance and functional movement.
