This study sought to compare foot and ankle mobility, foot posture and dynamic knee valgus, measured as the frontal plane projection angle (FPPA) during single-leg squatting, between individuals with and without PFOA. The authors found that foot and ankle characteristics were different in individuals with PFOA compared to control participants, however there was no difference in dynamic knee valgus during single leg squat. Clinical interventions to address greater foot mobility may be relevant for PFOA.

本研究旨在比較有和沒(méi)有PFOA的個(gè)體在單腿蹲時(shí)的足部和踝關(guān)節(jié)活動(dòng)度、足部姿勢(shì)和動(dòng)態(tài)膝關(guān)節(jié)外翻(以單腿蹲時(shí)的額平面投影角(FPPA)衡量)。作者發(fā)現(xiàn)，與對(duì)照組相比，PFOA患者的足部和踝部特征有所不同，但單腿深蹲時(shí)動(dòng)態(tài)膝關(guān)節(jié)外翻沒(méi)有差異。臨床干預(yù)以解決更大的足靈活性可能與PFOA相關(guān)。
