The abbreviations used are: # - number of subjects or specimens; Cor - coronal plane; Sag - sagittal plane; Ax - axial plane; Rot - rotation about the FHA; Trans - translation along FHA and SD - standard deviation. "Max PF-DF", "max Inv-Ev", and "Neutral to inverted" indicate that the FHA was defined as the change in joint attitude between two poses (extreme PF to extreme DF, extreme Inversion to extreme Eversion, and neutral to extreme inversion respectively).
