Table 1.

Pearson’s correlations between of the foot and the trunk within the given plane for root mean square (RMS) and approximate entropy (ApEn). RMS at foot is strongly correlated with RMS at trunk in sagittal and frontal plane. ApEn at foot is moderately correlated with ApEn at trunk in sagittal plane, but a weak non-significant correlation exists in the frontal plane.

Plane r – value (p – value)
Sagittal RMS 0.883 (<0.01)*
ApEn 0.603 (<0.01)*
Frontal RMS 0.811 (<0.01)*
ApEn 0.293 (0.07)
