JOINT MOBILIZATION CHANGES ACTIVATIONS IN GLUTEUS AND VASTI MUSCLES DURING FUNCTIONAL ACTIVITIES IN PEOPLE WITHOUT AND WITH PATELLOFEMORAL PAIN SYNDROME
Keywords: patellofemoral pain syndrome, joint mobilization, motor control, electromyography, vasti muscles
AbstractWe aimed to examine whether patellofemoral joint mobilization altered the activation in vasti and gluteus muscles in people with and without PFPS during functional activities. A total of 40 young collegiate students with and without PFPS were recruited. After the intervention of patellofemoral joint mobilization, there were significant earlier activations of vasti muscles and delayed activation of gluteus muscles such as heel rise, step up and down and drop landing in people with PFPS compared to that of healthy controls (p <0.05). Patellofemoral joint mobilization may immediately altered motor coordination of knee and hip muscles in people with and without PFPS during functional activities
