Fig. 6From: Effects of step frequency during running on the magnitude and symmetry of ground reaction forces in individuals with a transfemoral amputationMean ground reaction force impulse (GRI) parameters and linear regressions of both limbs across mean realized step frequencies at each metronome frequency. In every plot, the horizontal axis represents realized step frequency. Each plot represents a different parameter. Parameters are represented in respective vertical axis as: vertical GRI (BWs) (A), braking GRI (BWs) (B), propulsive GRI (BWs) (C), net braking-propulsive GRI (BWs) (D), medial GRI (BWs) (E), lateral GRI (BWs) (F), and net medial–lateral GRI (BWs) (G). Each circle indicates the mean of all the participant’s data at each increment of metronome frequency from − 20% to + 20%. Blue and red plots indicate intact and prosthetic limb, respectively. Significant main effects are indicated by filled circles, while main effects that were not significant are indicated by unfilled circles. Relevant R2 and P values for the linear regressions are also displayed in matching color to the intact or prosthetic limb. P < 0.001 indicates P values which were at or smaller than 4 decimal placesBack to article page
