The effect of proprioceptive neuromuscular facilities (PNF) stretching exercise on patellofemoral pain syndrome (PFPS)

Patellofemoral pain syndrome (PFPS) is a common disorder of the knee.­ the conservative treatment of patellofemoral pain syndrome is to correct shortness of soft tissue. The aim of this study was to determine the effect of PNF stretching exercise on PFPS.
Twenty female volunteers with PFPS were randomly assigned to PNF and control groups. The experimental group accomplished their own specific treatment protocols for 8 weeks, whereas the control group did not follow the treatment plan. Pain and functional disability were assessed by visual analogue scale (VAS) and Kujala questionnaire respectively, before and after exercise. Using SPSS 20 software, data were analyzed by t-test. P The experimental group showed a significant reduction in the pain (P We concluded that PNF stretching may have positive effects on PFPS.
