  1. Mean (SD) of step length, width, and foot progression angle (FPA) are shown. Further, mean (SD) of normalized ( Nm/(kg*m)*100) internal peak joint moments for right/hypermobile leg during stance phase, for NGJH (Non-Generalized Joint Hypermobility) and GJH (Generalized Joint Hypermobility) children, with p-values for effect of status. In sagittal plane positive/negative values designate dorsal-/plantar flexion in the ankle, extension/flexion in the knee and flexion/extension in the hip. In frontal plane positive/negative values designate abduction/adduction for both knee and hip. Significant differences (p-values <0.05) are marked in bold.
