Means and Standard Errors of the Angular drifts for the elongation conditions.

<p><i>AngleBefore</i> is the mean of 10 estimations of hand position at the start of the experiment. <i>AngleAfter</i> is the single estimation of hand position after the arm elongation period. <i>AngleAfter</i> is significantly greater than <i>AngleBefore</i> for <i>C2</i> (P = 0.04) and <i>C3</i> (P = 0.01) but not for <i>C4</i> (P = 0.17), Wilcoxon matched-pairs signed-rank tests.
