Before & After | Strong Knee Hyperextension | DAFO 3

This before-and-after video shows a young patient with strong knee hyperextension wearing DAFO 3s. The solid proximal-posterior upright of the DAFO 3s block her excess plantarflexion, preventing her from hyperextending at the knee. Because there is no proximal anterior strap, her leg is free to move into dorsiflexion.
