Influência dos fatores biomecânicos da pelve e dos membros inferiores na dor patelofemoral

Abstract

Despite the high incidence and prevalence of patellofemoral pain syndrome (PFPS) its causal factors are still not fully known. The etiology of patellofemoral pain has been widely studied and several theories have been proposed in an attempt to better explain it. The aim of this was to check the influence of biomechanical factors of the pelvis and lower limbs in patellofemoral pain, through a literature review. We searched the databases SciELO, Lilacs, PubMed and ISI Web of Knowledge. Among the factors associated with the syndrome, in literature, found an increased Q angle, the tension of the lateral structures of the knee, the tension of the anterior structures of the hip, the improper placement of the patella, the failure of the vastus medialis oblique or her delay in activation and excessive pronation. Factors that had a higher correlation with the performance of SDPF were hip muscle strength, and tension band ileotibial(BIT), the kinematics of the rearfoot and he delay in activation of the vastus medialis oblique (VMO) relative to vastus lateralis (VL). Therefore, it is suggested that these aspects should be included in physical therapy evaluation for the treatment of patients with PFPS.
