Purpose: Identify patients with patellofemoral pain syndrome (PFPS) who will likely have a positive immediate response to lumbopelvic manipulation.

Stage of CPR Development: Invalidated (Crowell et al., 2012).

Rule:

1. Difference in hip IR > 14 degrees
2. Ankle dorsiflexion with knee flexed > 16 degrees
3. Navicular drop > 3mm
4. No stiffness with sitting 20 min
5. Squatting is most painful activity
