Supervised exercise therapy vs home exercises

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · patients with patellofemoral pain syndrome (symptoms > 2 months (1 study); not stated (1 study))

It is very uncertain whether supervised exercises changes usual pain (long‐term) VAS (0 to 10; higher scores mean worse pain) compared with home exercises (very low certainty).

Target of exercise: hip vs knee exercises

Pain during activity (long‐term) VAS (0 to 10; higher scores mean worse pain) · patients with patellofemoral pain syndrome (symptoms > 1 month (1 study); symptoms > 6 months (1 study))

It is very uncertain whether target of exercise: hip changes pain during activity (long‐term) VAS (0 to 10; higher scores mean… compared with knee exercises (very low certainty).

Closed kinetic chain exercises vs open kinetic chain exercises

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · patients with patellofemoral pain syndrome (symptoms > 4 weeks (1 study); symptoms > 6 weeks (1 study); symptoms > 8 weeks (1 study); not…

It is very uncertain whether closed kinetic chain exercises changes usual pain (short‐term) VAS (0 to 10; higher scores mean worse pain) compared with open kinetic chain exercises (very low certainty).
