TABLE 3.

Results of the statistical analysis for the DTE on stabilo parameters across the three experimental groups (HCs, FMDs, OMDs). Data are expressed as mean ± standard deviation. The level of statistical significance was set at p < 0.05; post hoc comparisons were corrected using the Bonferroni method.

DTE: Dual task effect; OE: open-eyes; CE: close-eyes; motor dual-task; cDT: Cognitive dual-task; T: Task, G; Group; HC: Healthy control; FMD: Function motor disorders; OMD: Organic motor disorders. Bold p-values indicate statistical significance (p < 0.05). Superscripts applied to post hoc comparisons indicate in which groups the variation between tasks was significant: * indicates a significant difference observed in all groups; ^A indicates a significant difference only in the HC group; ^B indicates a significant difference only in the FMD group; ^C indicates a significant difference only in the OMD group. ηp² indicates partial eta squared, reported as a measure of effect size for the fixed effects of the model. According to Cohen’s conventions, ηp² values of 0.01, 0.06, and 0.14 correspond approximately to small, medium, and large effects, respectively
