Table 1.
Means (standard deviations) of the spatiotemporal parameters during walking in the adolescent idiopathic scoliosis group (AIS, n = 16) and healthy controls (Control, n = 16).
Fig 1.
Ensemble-averaged sagittal COM-COP inclination angle (IA), and sagittal rate of change of IA (RCIA) during level walking: convex-side limb leading (red line), concave-side limb leading (blue line) and controls (dashed).
The medial/lateral (M/L) positions of the COM and COP were described relative to the line of progression that described the M/L range of motion of the COM during a gait cycle, a positive value being to the side of the contralateral limb. (HS: heel-strike; CTO: toe-off of contralateral leg; CHS: heel-strike of the contralateral leg; TO: toe-off.) Positive sagittal and frontal IAs indicate COM positions that are anterior and contralateral to the COP, respectively.

Means (standard deviations, SD) of the jerk index (105°/s3) of the sagittal and frontal IA in the patients with adolescent idiopathic scoliosis and healthy controls during walking.
Fig 2.
Ensemble-averaged frontal COM-COP inclination angle (IA), and frontal rate of change of IA (RCIA) during level walking: convex-side limb leading (red line), concave-side limb leading (blue line) and controls (dashed).
The medial/lateral (M/L) positions of the COM and COP were described relative to the line of progression that described the M/L range of motion of the COM during a gait cycle, a positive value being to the side of the contralateral limb. (HS: heel-strike; CTO: toe-off of contralateral leg; CHS: heel-strike of the contralateral leg; TO: toe-off.) Positive sagittal and frontal IAs indicate COM positions that are anterior and contralateral to the COP, respectively.
