  1. *The values are given as the median with the range in parentheses. P-values were calculated by means of the exact Mann-Whitney-U test using a two-sided 0.05 level of significance.
  2. A p-value in bold type denotes a significant difference. n.s. = not significant.
  3. Abbreviations: total brake response time (TBRT), reaction time (RT), movement time (MT), brake force (BF), osteoarthritis (OA).
