From: Effects of extended powered knee prosthesis stance time via visual feedback on gait symmetry of individuals with unilateral amputation: a preliminary study

Fig. 3

With visual feedback, subjects attained greater anterior propulsion from their amputated limb with the powered prosthesis, more closely matching the propulsion of the intact limb. a Peak anterior propulsion of each limb (normalized to body weight) shown for both devices. Blue corresponds to the intact limb, and red corresponds to the amputated limb. b Peak anterior propulsion asymmetry index with mean values labeled and subjects distinguished by point characters (S1–5). All point characters represent the mean of 9 strides from each trial, and the lines connect the means. Subject 5 was not included in the means, as she did not have a passive prosthesis
