a, Bionic ankle mechanics of level-ground walking in a 10 m open hallway are shown at three walking speeds (n = 7 per cohort; bold lines, mean; shaded regions, s.e.m.). Study population walking speeds for each targeted speed are also reported (mean ± s.e.m.). b,c, Plots report neuromodulated bionic kinematics (b) and kinetics (c) for each walking speed (bars, mean; error bars, s.e.m.). d, The maximum walking speed for each cohort is shown, along with comparisons with the fast walking speeds of biologically intact individuals with similar body weights reported in the literature50 (bars, mean; error bars, s.e.m.). e, Lower-extremity joint trajectories at three targeted walking speeds are illustrated (bold lines, mean; shaded regions, s.e.m.). f, Plot reports LEK symmetry for each targeted speed (bars, mean; error bars, s.e.m.). For these analyses, two-sided paired and unpaired t-tests were used for within- and between-group comparisons, respectively, with Holm–Šidák correction for multiple comparisons (n = 7 per cohort, *P < 0.049, **P < 0.0096, ***P < 6.2 × 10−4). NS, not significant. Extended Data Figs. 3 and 4 report the biomimetic speed adaptation and LEK analyses in more detail, respectively.
