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.
