Table 3.
Values of average estimates and estimates of variability for the unipedal gait parameters with the following statistics: sample size (N), the bias: mean of (insoles-GAITRite®), SD of differences: SD of (insoles-GAITRite®), lower and upper limits of 95th CI of differences, Pearson’s correlation and intra-class correlation coefficients between GAITRite® and the insoles. (*) Note that the CI for the CV estimates are approximate only, based on t-intervals, as the underlying distribution is not known.
