Total sound limb power and work. Average power by the total sound limb (n = 12) (A) and mechanical work were computed in the entire stance (B) and during each of the four sub-phases: collision (C), rebound (D), preload (E), and push-off (F). Entire stance (B) and collision (C) showed stiffness effects. Faster walking speed produced greater work in the entire stance phase (B) and most sub-phases (CE). Preload (E) showed an interaction effect. Overall, the total sound limb produced net positive work in the entire stance phase (B). Significant stiffness, speed, and interaction effects are denoted by ‘*’, ‘ + ’, and ‘x’ symbols, respectively
