A força muscular do complexo póstero lateral do quadril e a mobilidade de tornozelo influenciam no controle motor de jovens com dor femoropatelar?

Abstract

Introduction: Patellofemoral Pain Syndrome (DFP) is characterized by pain in the anterior region of the knee, which is exacerbated during the performance of functional activities such as crouching, climbing and descending stairs and remaining seated for long periods. Objective: To compare the muscular strength of the Lateral posterolateral complex of the hip and the mobility of ankle dorsiflexion of the volunteers with DFP and healthy controls and to analyze the influence of these variables in the motor control of the lower limb in women with DFP. Methods: Observational study of cross-cutting with sample concealment. Thirty volunteers aged between 15 and 25 years participated in the research being divided equally into symptomatic group and asymptomatic. The motor control, ankle mobility and muscle strength were evaluated using a modified version of the Star Excursion Balance Test (SEBT), the LegMotion and the manual digital dynamometer, respectively. The project was approved by the Ethics Committee in research with human beings from the Federal University of Sergipe. Results: It was identified that there is no significant difference between the ankle mobility groups (P: 0.30) and the strength of the CPLQ (p: 0.18). However, the strength of the CPLQ influences the motor control in the lateral posterolateral direction (p: 0.02) and medial posterolateral (P: 0.02), since the ankle mobility does not influence the motor control (p: 0.48). Conclusion: It concludes that ankle mobility and CPLQ muscle strength are no different in women with DFP and asymptomatic women. It is also not a mobility of movement, but a motor of control that influences the power of the motor.
