Ankle Flashcards
movement at ankle joint in sagittal plane around a frontal plane axis
plantarflexion and dorsiflexion
movement at tarsal in frontal plane around a sagittal plane axis
inversion and eversion
movmeent at forefoot in transverse plane that accompanies inversion and eversion
abduction and adduction
combination of PF + inversion + adduction
Varus: term may be used to describe this position
supination
combination of DF + eversion + abduction
Valgus: term bay be used to desribe position
pronation
