“…However, recent studies have demonstrated lack of agreement between 2-dimensional changes in frontal plane knee position and 3-D joint kinematic variables such as knee abduction angle. 26,34 Thus, there may be a disconnect between focusing on improving 2-dimensional frontal plane alignment as a means of reducing peak 3-D knee joint angles. However, the purpose of this study was to determine whether a simple intervention could induce positive changes in 3-D joint kinematics that have been implicated to be related to ACL injury risk.…”

“…We instead compared our visual assessment with 2-D projection angles using video recordings. Projection angles, although not a direct substitute for 3-D angles, 14 are correlated with 3-D angles. 23 We believe our methods are a reasonable first step to validation that can be easily replicated in clinical settings that lack 3-D motion analysis.…”

“…O ângulo-Q foi mensurado, seguido pela avaliação do APPF durante step down (70,71) . Após esse procedimento foi avaliada a força muscular isométrica dos músculos rotadores laterais, extensores e abdutores do quadril e da força lateral de tronco (Core lateral).…”

“…Todas as participantes executaram três ensaios com 60 segundo de repouso para o início efetivo do teste (71) , cada step down foi realizado no período de 5 segundos referente à fase excêntrica e concêntrica, marcado com cronômetro. Os participantes em pé (1s) foram instruídos a realizar o step down lentamente até tocar o calcanhar do membro suspenso no solo (3s), e voltar lentamente para posição inicial (5s).…”
