been reported ( r  = .66, P  < .001) and does not appear to be influenced by age. 19 In addition, postural sway was measured with an AMTI AccuSway Force Platform (Watertown, MA) at a sampling rate of 50 Hz and filter frequency of 15 Hz. The filter used was a fourth-order Butterworth implemented as an

posture, the pivot point is the hip and ankle, respectively. The inertial mass below the pivot point is larger when sitting because the legs and the gluteal region is in contact with the force platform. This large inertial mass relative to standing (when the only segment in contact with the platform is

Experimental Apparatus and Testing A 3D force platform (Balance Plate 6501, Bertec Corp., Columbus, OH, USA) was used to measure CoP displacement during static and dynamic balance performance. Angular displacement of

. An eight-camera motion capture system (Oxford Metrics Limited, West Way, Oxford, UK) sampling at 200 Hz was synchronized with two force platforms (Advanced Mechanical Technology, Inc., Watertown, US), embedded midway on the walkway sampling at 1,000 Hz. Reflective markers were affixed to the right

Thirty-nine reflective markers were positioned at specific anatomical landmarks according to the full-body Plug-in gait model (Vicon, Oxford, UK). Two force platforms (Kistler, Winterthur, Switzerland) embedded in the walkway were used to collect
