Background Angelman syndrome ( AS ) leads to clinical manifestations that include intellectual impairments, developmental delay and poor motor function. Initiatives to develop therapeutics implie an urgent need to identify methods that accurately measure the motor abilities. Methods Six children with AS (6 to 9 years old) walked on an instrumented walkway to get spatiotemporal parameters ( STP s) and center of pressure (CoP). These outcomes were compared to typically developing children ( TD ): 44 TD 6 to 9 years old and 20 TD 4 to 5 years old. Results Analysis revealed differences in all STP s and gait variability index when compared to TD individuals. When AS participants were compared to younger TD individuals, except step length, STP s were different. Analysis of the CoP pathway revealed a less consistent and efficient pathway in AS . Conclusions We could delineate the functional difference between children with AS and TD children. The variability of STP and the CoP were the most valuable components in gait to be considered in AS .
