Term Description

Postural sway is recorded for each pose using an accelerometer that the participant wears at waist level.

Normalized path length scores are first calculated from the anterior-posterior postural sway data as follows:
Normalized Path Length = 1/t ∑_(j=1)^(N-1) x〖|p_(j+1)-p_j |〗
Where t is the time duration, N is the number of time samples, and pj is accelerometer data at time sample j. The normalized path length scores from the continuous anterior-posterior (AP) sway data are then recoded into a 5-point ordinal scale, with higher values representing better balance and less sway (i.e., AP sway 0-.005 = 5, > .005-.015 = 4, > .015-.025 = 3, > .025-.045 = 2, > .045 = 1).
