Trunk Stability

  1. Determine YZ values of pelvis and spine-high joint center values at timepoint of max knee flexion
  2. Calculate the difference in Y and Z between pelvis and spine-high joint centers
  3. Calculate trunk lean angle by inverse tangent of difference in Y over difference in Z
  4. Metric calculated for Step Down, Lateral Shuffle, Triple Jump, Deceleration, Cut.
Score Scoring Definition Significance
0 Trunk Lean is greater than 10 degrees Significant Trunk Lean
1 Trunk Lean is greater than 6 degrees Mild Trunk Lean
2 Trunk Lean is less than 6 degrees No Trunk Lean
