Diff Max Head

the difference in maximum head height that occurs before RF weight bearing compared to before LF weight bearing. Ref range: -6.0 to +6.0 mm

  • Measured in mm and reported as a mean value of all strides.
  • Diff Max Head determines timing of asymmetry (depending on sign of Diff Min Head).
  • Diff Max Head = Max height of head before RF weight bearing minus (-) max height of head before LF weight bearing. 

Diff Max Pelvis

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.



Diff Min Head

the difference in minimum head height that occurs during RF mid stance compared to during LF mid stance. Ref range: -6.0 to +6.0 mm 

  • Measured in mm and reported as a mean value of all strides. 
  • Diff Min Head determines side of asymmetry (positive value = RF, negative value = LF). 
  • Diff Min Head = Min height of head during RF mid-stance minus (-) min height of head during LF mid-stance.

Diff Min Pelvis

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
