From: Cortical correlates in upright dynamic and static balance in the elderly
(a) Sensor location and adjusted sensitive axes: anterior-posterior (AP), medial-lateral (ML) and vertical (VT) direction of the center-of-mass (CoM) trajectory, as estimated via the sensor placed on the fifth lumbar vertebra (L5). Balance control performances during static (0%, ± 22%) and dynamic postural (Core board) tasks in (b) single-task and (c) dual-task for elderly and younger adults. d) Within-group statistical differences (i.e., single- vs. dual-task) in each postural condition for elderly and younger adults, and between-group differences (i.e., elderly vs. young) in each postural condition in dual-task conditions. No significant differences were detected for single-task in between-group comparisons. Statistical differences among conditions are highlighted in panel b) and c). Variables: Range of Motion (ROM), Sway Path length (SP), 95% Confidence Ellipse Area (CEA).
