This study investigated changes in gait and coordination variability in persons with Multiple Sclerosis (MS) after an 8-week rehabilitation intervention. Data for eight participants (Control: 4, Intervention: 4) were analyzed via Cortex Motion Analysis software and Visual 3D to calculate knee and ankle joint angles as well as discrete spatiotemporal parameters. The knee and ankle joint angles were further analyzed using a vector coding technique to quantify coordination between these joints and how they produce a functional gait pattern. No significant changes in gait or coordination variability were found after rehabilitation, but some meaningful changes with large and moderate effect sizes were present. This study demonstrated a comprehensive overview of the relationship between process and outcome variability in a clinical population.
