A alteração do controle motor e força dos membros inferiores pode promover o surgimento da dor femuropatelar?

Abstract

Introduction: Patellofemoral pain (DPF) refers to pain behind or around the kneecap, compounded by activities that burden the knee joint during weight bearing. Objective: Compare the motor control, the strength of hip, knee and foot of the volunteers with DPF with healthy controls; secondarily, correlate and verify the influence of muscle strength in the lower limb motor control in women with DPF. Methods: Cross-sectional delineation study, approved by the ethics and Research Committee of the UFS (68030117.3.0000.5546) and performed with 30 women in group 02 (symptomatic and asymptomatic). Motor control was evaluated through the Star Excursion Balance Test (SBET), directions previous (A), posterior medialis (PM) and posterior side (PL). Muscle strength was measured with the manual digital dynamometer, through the maximum voluntary isometric contraction (CIMV). Results: It was observed a reduction in the strength of the flexors of the knee (p=0,01) and tibialis posterior (p=0.01), as well as smaller motor control previous (p= 0.01), posterior medialis (p=0.01) and posterior (p=0.01) in the symptomatic group. In regression analysis it was found that the strength of the posterolateral complex of the hip (p=0.02) and knee extensor (p=0.02) influence on motor control PL, while the strength of the abductor hallucis (p=0.01) influences towards PM. Conclusion: Women with DPF feature reduction of muscle strength of knee flexors and tibialis posterior. The strength of the knee extensors, CPLQ, posterior tibial and abductor hallucis influence in motor control of infeiores members, in the directions PM and PL.
