High‐intensity vs low‐intensity exercise programmes

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · patients with patellofemoral pain syndrome (untreated PFPS of over 2 months in duration)

It is very uncertain whether high‐intensity changes usual pain (short‐term) VAS (0 to 10; higher scores mean worse pain) compared with low‐intensity exercise programmes (very low certainty).

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).

Target of exercise: hip + knee vs knee exercises

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · patients with patellofemoral pain syndrome (symptoms > 1 month (3 studies); symptoms > 2 months (1 study); symptoms > 3 months (2…

It is very uncertain whether target of exercise: hip + knee changes usual pain (short‐term) VAS (0 to 10; higher scores mean worse pain) compared with knee exercises (very low certainty).

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 (short‐term) VAS (0 to 10; higher scores mean worse pain) compared with home exercises (very low certainty).
