Shock Absorption
- Determine XZ values of knee and hip joint centers at timepoint of max knee flexion
- Calculate the difference in X and Z between knee and hip joint centers
- Calculate the thigh angle by inverse tangent of difference in Z over difference in X
- If thigh angle is less than 30, score is 2
- If thigh angle is greater than 45, score is 0
- Otherwise, score is 1
