Fig. 4From: Assessment of dynamic balancing responses following perturbations during slow walking in relation to clinical outcome measures for high-functioning post-stroke subjectsKinematics and kinetics following inward perturbation. a CoMML trajectories and GRFML and CoPML signals (mean values and standard deviations) for representative healthy subject and representative right-sided hemiparetic subject over one gait cycle. b ΔCoMML shown for all subjects along with covariance error ellipse. c Group mean values and standard deviations for the ΔCoMML averaged for perturbations occurring at heel contact of left (L) or right (R) leg for group of healthy subjects and for perturbations occurring at heel contact of non-paretic (NP) or paretic (P) leg both subgroups of stroke subjects; note that a sign for red bars has been changed to facilitate visual comparison d Group mean values and standard deviations for the ΔGRFML averaged for perturbations occurring at heel contact of left (L) or right (R) leg for group of healthy subjects and for perturbations occurring at heel contact of non-paretic (NP) or paretic (P) leg both subgroups of stroke subjects – “in-stance” period of response; note that a sign for blue bars has been changed to facilitate visual comparison. e Group mean values and standard deviations for the ΔGRFML averaged for perturbations occurring at heel contact of left (L) or right (R) leg for group of healthy subjects and for perturbations occurring at heel contact of non-paretic (NP) or paretic (P) leg both subgroups of stroke subjects - “stepping” period of response; note that a sign for blue bars has been changed to facilitate visual comparisonBack to article page
