the difference in minimum pelvis height that occurs during RH mid stance compared to during LH mid stance.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 Min (either + or -) correlates to an impact lameness in the hind limb.
• Diff Min Pelvis = Min height of pelvis during RH mid-stance minus (-) min height of pelvis during LH mid-stance
