(A) peak pressure, (B) maximum force, (C) pressure-time integral, (D) force-time integral. The reduction of foot load with a physical strain trainer was assessed by pedobarography. Two different regions of the foot (hindfoot and total foot) were analyzed for maximum force, peak pressure, pressure-time integral, and force-time integral (mean ± SD). Black spots illustrate values from normative gait, gray spots represent the limitation to 50% BW, and white columns show results from 10% BW. +, P<.05 compared with normative gait. *, P<.05 compared with hindfoot values with 10% BW. #, P<.05 compared with hindfoot values with 50% BW.
