Fig. 6From: Gait variability following abrupt removal of external stabilization decreases with practice in incomplete spinal cord injury but increases in non-impaired individualsFrontal plane kinematics for highly-challenged participants. Frontal plane kinematics for (a) a highly-challenged non-impaired participant (left column) and (b) a highly-challenged participant with iSCI (right column) during the transition steps (the time constant for Transition 1 for all participants combined was 15 steps) for Transition trials and corresponding time periods for Null trials. The highly-challenged non-impaired participant maintained narrow step widths during Transitions 1–3 and exhibited significant variability in COM motion during Transitions 1 and 2. The highly-challenged participant with iSCI never reached steady state during the entire length (100 steps) of the unassisted period following removal of the stabilizing field. However, this individual showed savings in improved control of COM motion by Transition 3Back to article page
