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 degrees, score is 0.
- If Pelvic Drop is less than 10 degrees & greater than 5 degrees, score is 1.
- If Pelvic Drop is less than 5 degrees, score is 2.
| Score | Scoring Definition | Significance | |||
| 0 | Pelvic Drop is greater than 10 degrees | Significant Pelvic Drop | |||
| 1 | Pelvic Drop is greater than 5 degrees | Mild Pelvic Drop | |||
| 2 | Pelvic Drop is less than 5 degrees | No Pelvic Drop |
