Table 3.
Values of the postural evaluation parameters with static and dynamic posturography: unstable platform, sinusoidal or trapezoidal platform oscillations, for Face-to-Face Training Group and Videoconference Training Group before (T1) and after (T2) the training period. SA—the sway area, SD—Standard Deviation of the postural sway along the Anterior-Posterior axis (AP) and Medial-Lateral axis (ML) or of the angle of the platform tilt. EO—eyes open, EC—eyes closed. Sign.—Significance level * p ≤ 0.05; a: intervention effect (corresponds to a significant effect of intervention for both groups), b: interaction effect (corresponds to a significant effect of intervention that is different between groups).
