Mean (SD) peak ground reaction forces for right/hypermobile leg during stance phase normalized to % Body Weight N/(kg*9.81) *100, for NGJH (Non-Generalized Joint Hypermobility) and GJH (Generalized Joint Hypermobility) children, with p-values for effect of status. Significant differences (p-values <0.05) are marked in bold.
F = Force z = vertical direction, y = anterior-posterior direction, x = medial-lateral direction 1,2,3 = peak number.
