Fig. 7

Left: Boxplots of the average GRF degree of asymmetry (\(DoA_\text {GRF}\)) for each participant and condition during the repeated rapid sit/stand test. More positive values indicate favoring the biological limb, while more negative values indicate favoring the prosthetic limb. Zero indicates perfect symmetry. Right: The estimated changes in GRF DoA due to each condition from the PRES baseline for each mobility level based on the best-fit LMM of the data. For the sitting data, the best-fit LMM did not show a statistically significant improvement over a null model (\(p=0.057\)). Error bars indicate 95% confidence intervals
