Fig. 6From: Isolating the energetic and mechanical consequences of imposed reductions in ankle and knee flexion during gaitΔTotal average positive joint power versus Δnet metabolic rate. The subject averaged (N = 15) Δnet metabolic rate and Δtotal average joint power show no statistically significant correlation and appear to have a negative correlation indicating that positive work is not an appropriate estimate of metabolic cost in atypical gait. No significant linear correlation was found using Pearson’s linear correlation coefficientBack to article page
