Time, WB: affected limb weight-bearing at seat-off; COPx and COMx: COP and COM displacement in the frontal plane, respectively; COPx_mid and COMx_mid: distance between the COP and COM position and the midline between the malleoli in the frontal plane at seat-off, respectively; positive and negative values reflect a position toward the unaffected and affected limb relative to midline, respectively; COPy and COMy: COP and COM displacement in the sagittal plane, respectively; COPy_mid and COMy_mid: distance between the COP and COM position relative to the midpoint between the malleoli in the sagittal plane at seat-off, respectively; positive and negative values reflect a position anterior and posterior to the midpoint, respectively. SB1, SB2, SB3, and SB4 = 2.54, 5.08, 7.62, and 10.16 cm solid blocks, respectively. CB1 and CB2 = 2.72 and 6.63 kg compliant blocks, respectively. Quart and half: quart-foot and half-foot asymmetrical conditions.
