Gait Deviations Flashcards
Progression of gait over the supporting foot requires what?
Rockers
What is the first rocker?
First – motion of foot from dorsiflexed to plantarflexed position during LR to achieve foot flat
What is the Second rocker?
Second - Closed chain advancement of the tibia into a dorsiflexed position over a fixed foot during MSt
What is the Third rocker?
Third - Begins when center of pressure is over the mets and heel lift occurs in TSt/PSw
