Ultrasonography of Knee Muscles During SLR With Different Positions of Hip and Ankle in Patellofemoral Pain Syndrome

Objective Due to the substantial prevalence of patellofemoral pain syndrome and importance quadriceps strengthening in knee rehabilitation, determining best way activate strengthen patella stabilizing muscles is considered as one important keys treatment. The aim this study evaluate effect different hip rotations associated with ankle dorsiflexion during maximal straight leg raising (SLR) maneuver sitting position on thickness fibers angle vastus medialis oblique (VMO) lateralis (VL) using ultrasonography. Materials & Methods This quasi-experimental was performed 40 individuals (healthy group: 20, [PFPS] 20). VMO VL fiber were measured ultrasonography SLR 6 positions: internal, external, neutral without dorsiflexion. Results In between-group comparison, no significant difference found for all variables maneuvers (P>0.05). within-group external rotation compared other positions resulted a increase both groups (P<0.05). Also, adding significantly increased VL. Conclusion By changing or SLR, trend changes two followed same pattern. Moreover, performing can be recommendable rehabilitation PFPS.
