 ====== Hip Stability ======
-  * Determine YZ joint center positions of the respective limb’s Ankle, Knee, and Hip
+  - Determine YZ joint center positions of the respective limb’s Ankle, Knee, and Hip
+  - Calculate the respective differences in Y and Z between the Knee and Hip joint centers, and Ankle and Knee joint centers.
+  - Calculate segment angles for the thigh and shank segments by taking the inverse tangent of the Z difference over difference in Y.
+  - Calculate the Knee valgus angle by subtracting the thigh segment angle from the shank segment angle.
+  - Metric calculated for Step Down, Drop Jump, Lateral Shuffle, Triple Jump, Deceleration, Cut.
-  * Calculate the respective differences in Y and Z between the Knee and Hip joint centers, and Ankle and Knee joint centers.
+|| Score || Scoring Definition  || Significance||
+|| 0 || Knee valgus angle is less than -10 degrees || Significant Knee Valgus||
+|| 1 || Knee valgus angle is less than -5 degrees || Mild Knee Valgus||
+|| 2 || Knee valgus angle is greater than -5 degrees || No Knee Valgus||

-  * Calculate the Knee valgus angle by subtracting the thigh segment angle from the shank segment angle.
-  - If Knee valgus angle is greater than -5, score is 2.
-  - If Knee valgus angle is less than -10, score is 0.
-  - Otherwise score is 1.
