  1. Factors: Group (two levels: elderly (E) and young (Y)), Condition (four levels: Real Environment (RE), Virtual Environment (VE), Medio-lateral Perturbations (ML) and Antero-posterior Perturbations (AP)) and Time (two levels: minutes 1and 5). Spatiotemporal Gait Outcome Variables: Stride Length (SL), Stride Length Variability (SLV), Stride Width (SW), Stride Width Variability (SWV), Stride Time (ST), Stride Time Variability (STV), Stride Velocity (SV) and Stride Velocity Variability (SVV). Statistically significant p values (p < 0.05) are bolded.
