  1. The assessment conditions and mean coefficient of variation (CV) for each COP parameter between the 3 trials are reported. The mean values between conditions for each COP parameter (last column) or COP parameters for each condition (last row) are in italic characters. Bold faced numbers in the last column identify the lowest CV values among COP parameters.
