Statistical analysis on Mean Magnitude-Squared Coherence (MSC) between trunk and leg accelerations at lower and higher frequencies and on cancellation-index (CI): (a) the main effect of health (iSCI vs AB), surface (FS vs. HS), and vision (EC vs, EO) conditions; and interaction effect of (b) surface and vision conditions, (c) health and surface conditions, and (d) health and vision conditions. Italic numbers show significant difference (p-value < 0.05)
