Comparison of the Effect of Three Combined Training Methods on Pain and Function in Patients with Patellofemoral Pain Syndrome

Background and Objectives: Patellofemoral pain syndrome is a common orthopedic disorder in knee joint, which causes pain and dysfunction. This study aimed to compare the effect of three combined training methods on pain and function in patients with patellofemoral pain syndrome. &nbsp; Methods: In this semi-experimental study, 30 individuals were selected from 65 male patients with patellofemoral pain syndrome, and randomly and evenly divided into three groups of experimental group 1, experimental group 2, and experimental group 3. The groups performed their own exercise for 8 weeks. Before and after the trainings, pain and function were analyzed using pain (VAS) and function (WOMAC) questionnaires. Data were analyzed using simple analysis of variance test (p<0.05). &nbsp; Results: ANOVA revealed a significant difference among the three groups in terms of pain (F (2, 27)=47.8, p<0.01) and function (F (2, 27)=44.3, p<0.01). Also, post-hoc test showed a significant difference between experimental group 1 and 2 (p<0.05) and experimental group 1 and 3 (p<0.01) in terms of pain and function, but there was no significant difference between experimental group 2 and 3 for pain and function (p>0.05). &nbsp; Conclusion: Following these exercises, reduction in pain and improvement in function, were observed in the three groups. Also, recovery rate in the experimental group 1 was higher than other groups, therefore, this new method can be introduced for the treatment of patients with patellofemoral pain syndrome. &nbsp; &nbsp
