Abstract

Purpose:
Disruption in biomechanics and kinematics of the lower extremity is one of the causes of knee patellofemoral pain syndrome. The purpose of this study was Comparison the effect of selected lower extremity movement pattern and traditional exercises on pain and quality of life in male athletic with patellofemoral pain syndrome.
Methods:
The Present research was semi-experimental and pre-test and post-test.The statistical population of this research is all men aged 18-28 years old with patellofemoral pain in Shiraz city who referred to Hadi sports medicine clinic. A number of 30 people from the aforementioned community were randomly and available purposefully selected and randomly placed in two movement pattern groups (15 people) and traditional (15 people). Subjects signed a personal consent form before participating in the exercise program. Each group had their own exercises for eight weeks, three sessions each week, and each session lasted 60 minutes. Before and after the training period, pain and quality of life were measured using visual pain measurement scale (VAS) and quality of life (SF-36), respectively. To were analyze the data, statistical test of variance was used for covariance data at a significant level (p<0.05).
Results:
The results showed that the exercise program for correcting the movement pattern of the lower extremity significantly improved the level of pain (ES=0.7, P<0.05 and F(1,28)=15.32) and quality of life (P>0/005 and F(1,28)=27/02 , ES=0/6). Also, the results showed that the traditional exercise program significantly improved the pain level (ES=0/5, P<0.05, and F(1,28) =8/24) and quality of life (ES=0/4, P<0.05 , F(1,28)=27/02 ). The exercise program was effective in both groups, but the exercises in the movement pattern group were more effective on pain and quality of life than the traditional group.
Conclusion:
The biomechanics of the lower extremity are disturbed in patients with patellofemoral pain syndrome, and the exercises performed on these people should cause changes in the biomechanics of the lower extremity and finally align the joints.
