Exercícios que influenciam na diminuição do valgo dinâmico de joelho em adultos jovens

Abstract

The hip, knee and foot misalignment produces dynamic knee valgus and this altered movement pattern has been associated with various injuries in the lower limbs. These biomechanical changes may be related to excessive adduction, internal rotation of the hip, contralateral pelvic drop, knee rotation and foot pronation. These dynamic changes of the hip may be occurring due to abductor muscles and external hip rotators weakness, mainly gluteus maximum and medius. Currently, there is evidence that strengthening the hip and knee doesn't by itself alter biomechanical standards, but associated with neuromuscular training, plyometric training and balance improve the biomechanics of the lower extremities. Therefore, the aim of this study was to review the literature about which exercises reduces the dynamic knee valgus. The narrative review of the literature was performed by searching the Pubmed Database, Medline, PeDro, Lilacs, Scielo and Bireme being included nine articles, five experimental studies', cross- sectional study article and three randomized controlled trials. According to the results of the studies reviewed, exercises aimed to increase external rotator and abductors muscles strength, quadriceps and hamstrings associated with neuromuscular, plyometric and balance training can improve lower limb biomechanics, decreasing dynamic knee valgus, providing a sufficient stimulus to promote changes in muscle recruitment strategies that modify the kinematics of the lower limbs
