Whole cord mean and standard deviation (in parenthesis) are reported. Means and standard deviations of the reproducibility index, calculated using Eq. (5), are also shown for Subject 1.

aRefers to significantly improved reproducibility as measured by the Kolmogorov‐Smirnov test (P‐value < 0.05) on distributions of I over the whole cord for either the uniform or optimal protocol when compared to one another. Inter‐subject mean and CV are given at the bottom.
