Before & After | Knee Hyperextension | JumpStart Kangaroo

In this before and after video, a young girl wears JumpStart Kangaroos to help control her knee hyperextension. The solid proximal-posterior upright of the JumpStart Kangaroo blocks her plantarflexion, preventing her from hyperextending at the knee. Because there is no proximal anterior strap, her leg is free to move into dorsiflexion.
