Median values and range are presented, as also mean value and standard deviation. Paired comparison of affected (by coup de sabre, ipsilateral, A) vs. healthy (contralateral, H) by Wilcoxon matched pairs test. The calculated individual A minus H parameter by t-test, as differing from zero, all in agreement with the non-parametric Wilcoxon
