the difference in maximum pelvis height that occurs before RH weight bearing compared to before LH weight bearing. Ref range: -3.0 to +3.0 mm

• Measured in mm and reported as a mean value of all strides. 
• RH asymmetries are assigned (+) values. LH asymmetries are assigned (-) values.  Elevated Diff Max (either + or -) correlates to a push off lameness in the hind limb. 
• Diff Max Pelvis = Max height of pelvis before RH weight bearing minus (-) max height of pelvis before LH weight bearing.
