Pelvis Stability
- Determine YZ values of left and right hip joint centers at timepoint of max knee flexion
- Calculate the difference in Y and Z between left and right hip joint centers
- Calculate pelvic drop angle by inverse tangent of difference in Z over difference in Y
- Metric calculated for Step Down, Triple Jump, Deceleration, Cut.
- If Pelvic Drop is greater than 10, score is 0
- If Pelvic Drop is less than 5, score is 2
- Otherwise score is 1
