عنوان فارسی
چکیده فارسی مقاله Purpose: To investigate the electromyographic activities and balance of vastus medialis obliquus (VMO) and vastus lateralis (VL) muscles during straight leg raise (SLR) in individuals with and without patellofemoral pain syndrome (PFPS). Method: Through an analytical case-control study, 26 persons with PFPS and 26 healthy subjects recruited with non-random and available sampling method. All subjects performed SLR movement. The EMG activity of VMO, VL and VMO/VL ratio were measured. The muscles activation level compared between two groups using independent t-test. Data analyzed using SPSS software version 18. Results: The mean and maximum of EMG activity of VMO, VL and VMO/VL ratio didn't have any significant differences between PFPS and healthy groups (p>0.05). In other words, during SLR the VMO and VL muscles activated in PFPS group approximately the same as healthy group. Conclusion: These data suggest that not all individuals with PFPS had quadriceps weakness. Many factors may contribute to PFPS that should be considered in assessment and rehabilitation of individuals with PFPS

عنوان انگلیسی Comparing Electromyographic Activities and Balance of Vastus Medialis Obliquus and Vastus Lateralis Muscles During Straight Leg Raise in Individuals With and Without Patellofemoral Pain Syndrome
چکیده انگلیسی مقاله Purpose: This study aimed to investigate the electromyographic activities and balance of Vastus Medialis Obliquus (VMO) and Vastus Lateralis (VL) muscles during Straight Leg Raise (SLR) in individuals with and without Patellofemoral Pain Syndrome (PFPS). Methods: Through an analytical case-control study, 26 persons with PFPS and 26 healthy subjects were recruited by non-random and convenience sampling method. All subjects performed SLR movement. The EMG activity of VMO, VL and VMO/VL ratio were recorded and measured. The muscles activation level were compared between the 2 groups using the Independent t test. The obtained data were analyzed using SPSS.  Results: The mean and maximum EMG activity of VMO, VL and VMO/VL ratio did not have any significant differences between the PFPS and healthy groups (P>0.05). In other words, during SLR, the VMO and VL muscles activation in the PFPS group were approximately the same as the healthy group.  Conclusion: These data suggest that not all individuals with PFPS had weak quadriceps muscles. Many factors may contribute to PFPS that should be considered in the assessment and rehabilitation of individuals with PFPS.
