Abstract

Purpose: The aim of the current research was the effect of closed kinetic chain exercises on reducing pain in women with patellofemoral pain syndrome.

Methods: The current research was semi-experimental and laboratory type. In the above study, 30 women were divided into two groups of 15 people, including the group with patellofemoral syndrome and the healthy group. The inclusion criteria of the subjects in the group with patellofemoral syndrome was pain above three, and the exclusion criteria included having a history of surgery, joint replacement, artificial limb, and neuromuscular diseases. Both groups performed closed chain exercises that included regular squats, wall squats, ball squats, regular lunges, claw point flex, isometric foot wall exercises, hip bridges, and planks for eight weeks and three sessions in twenty weeks. And they did four sessions. Before and after the intervention, the amount of pain was measured using the analogue pain scale (vas) and the maximum oxygen consumption was measured using the Rockburt one-mile test. For statistical analysis of the data, spss software version 23 and covariance test and paired t-test were used at a significant level (P<0.05).





Results: The findings of the research showed that there is a significant decrease in the amount of pain in the group with patellofemoral syndrome after closed kinetic chain exercises (p=0.001). On the other hand, there was a significant increase in the maximum oxygen consumption in the healthy group (p=0.001).

Conclusion: Closed kinetic chain exercises can reduce pain and increase maximum oxygen consumption in people with patellofemoral syndrome.
