This video, narrated by the patient's pediatric physical therapist Gay Burton, follows 3-year-old Diane during a PT session. Diane has a diagnosis of cerebral palsy (spastic diplegia) and has spasticity in her lower extremity. Her ankles are in a plantarflexed position and she hyperextends her knees for stability. Diane wears a pair of prefabricated plantarflexion block orthoses (Cascade Dafo's JumpStart Kangaroos). The video includes explanation of various PT exercises during a typical session with Diane.
