Figure 1.

Posturography before (filled bars) and after (striped bars) schwannoma surgery in the 3 groups during (a) quiet stance and (b) perturbed stance. The values represent the mean and the error bars; standard error of mean (SEM). The Bonferroni corrected significant level for between-groups comparisons is set to p < 0.025 (in bold), but for consistency reasons p < 0.05 is also presented as trends (unbolded). The Bonferroni corrected significant level for within-subjects comparisons is set to p < 0.05.
