Among thirteen patients with patellofemoral pain that performed a slow step down during three randomized conditions (no intervention, patella taping, patellofemoral bracing) it was noted that the taping and bracing reduced the coronal plane knee movements and bracing also decreased the transverse plane knee movements. While more research is needed to describe how these findings relate to symptoms this data suggests that these interventions influence mechanics.
