Product Features

The JumpStart Kangaroo was developed to help young patients with fully-correctable pronation or supination and excess plantarflexion re-align their base of support to improve stability in standing and walking. Use of the Kangaroo encourages more practice in dorsiflexed positions for patients who present with excess toe walking or knee hyperextension. Full wrap-around flexible support encompasses the foot and ankle for pronation and supination control, and the well-defined plantar surface provides proprioceptive input. Proximal, posterior AFO trimline blocks excess plantarflexion, encouraging knee flexion and tibial movement over the foot. Solid outer foundation adds extra arch support, heel stability and strength for block to excess plantarflexion.
