The means of the C0-C10 of the 37 subjects, in blocks of individual subjects, were tested, whether they were identical at the six positions (right inch, right bar, right cubit, left inch, left bar, and left cubit). DOF means degrees of freedom. Wilks’s lambda represents the ratio of the intragroup square sum over the total square sum, and Approx F represents the F-statistic of Wilks’s lambda after the transformation; denotes p<0.05.
