Fig. 3From: Biomechanics and energetics of walking in powered ankle exoskeletons using myoelectric control versus mechanically intrinsic controlNet Metabolic Work Rate for Each Walking Condition. All net metabolic work rates are normalized to subject mass and represent the absolute changes in energetics for each walking condition. Error bars are ±1 s.e.m. from the mean of each condition. The percentages above each powered condition represents the percent decrease in energetics compared to the unpowered conditionBack to article page
