From: Independent effects of adding weight and inertia on balance during quiet standing
COP measures of balance. (a) Mean COP position measured from the lateral malleoli. Positive numbers indicate anterior to the lateral malleoli. (b) Range of COP position. (c) Mean COP speed. (d) Range of COP speed. B – baseline, I – added inertia only, W – added weight only, IW – added inertia and weight. Conditions not connected by the same letter are statistically different.
