Shear Modulus (Stiffness) of Right and Left Lateral Gastrocnemius Muscles With Passive Stretch Among Children. There is no significant difference in stiffness between the right and left sides at the same foot position. * indicates that values for each foot position on the right differed significantly from each other (P<.001). # indicates that for each foot position on the left, the values differ significantly (P<.001) from each other. The bars indicate 1 SD from mean value for each foot position. Foot position is in degrees of plantar flexion (PF) and dorsiflexion (DF), with 0° PF being the neutral position. kPa indicates kilopascal.
