A standing platform for a child designed to slant the surface on which the feet are placed to create a slope angle to therapeutically stretch the ankle plantar flexion muscles/tendons. It is intended to be used in the treatment of various medical conditions (e.g., congenital, neurological, post-traumatic) where tendon tightness and muscle contracture affect the ability to dorsiflex the foot, possibly leading to an abnormal gait. It is typically made of synthetic polymer materials. This is a reusable device.
