a Self-selected walking speeds measured in the lab for participants using the unpowered (red) and powered (blue) prostheses. Gray x’s and lines represent individual participant trends. b Split violin plot of the probability density functions of walking speed distributions of walking strides taken in daily life. To visualize, raw distributions were smoothed using the ksdensity kernel smoothing function in MATLAB. Shared regions are averaged distributions and solid horizontal lines are the group means
