Abstract
Background Instrumented treadmills that provide basic gait parameters in near real–time are emerging as valuable outcome tools in both clinical and research settings. Significant changes in step length and peak vertical force in the order of 2cm and 20-70N have been reported with footwear interventions and neurological disorders using these systems. However, published data about the systems’ measurement properties is lacking. This study evaluated the within– and between day repeatability of spatiotemporal parameters and vertical ground reaction forces (vGRF) measured by a new instrumented treadmill system.
