Fig. 5From: Isolating the energetic and mechanical consequences of imposed reductions in ankle and knee flexion during gaitTotal average positive joint power and Δtotal average positive joint power tend to decrease with joint restriction. Restriction of the knee (restricted-knee, restricted-a + k) resulted in reduced a subject averaged (N = 15) total average positive joint power compared to the braced condition, and the restricted-a + k condition was significantly reduced in comparison to the restricted-ank condition. b Subject averaged (N = 15) Δtotal average positive joint power in the restricted-a + k condition was significantly more negative than the Δtotal average positive joint power in the restricted-ank condition. All a, b error bars are mean ± s.e.m. Asterisks indicate a statistically significant difference (post-hoc paired t-test with Bonferroni correction for multiple comparison, p < 0.05)Back to article page
