Classification of low, medium, high delineate the relative contribution of each parameter during this intervention; where selected interventions vary in their application of some of these interventions (* - traditional exercise may provide practice of variable tasks but not variable stepping practice; ** -AFOs and FES systems in themselves may allow greater practice)
