Table 2.

The distributions of the slopes (i.e. the best fit linear regression line for the ratio of SSCT to tendon motion) for simultaneous (fist) and single digit movement. P values are from the Wilcoxon signed rank test for comparisons between median simultaneous and differential finger movement within each group. Mean, minimum and maximum data are included to give an idea of the skewness of the data.
