In Cerebral Palsy (CP), orthotic devices are used to prevent musculoskeletal deformities, and in the assistance of functionalities such as walking in both pre- and post-operation phase. The most commonly used equipment is Ankle-Foot- Orthosis (AFO). Different types of AFOs are used for different types of deformities. Studies on robotic systems used alongside classical equipment that assist in walking will continue to take place. Can these new devices replace classical orthosis devices? In this review, we will discuss new and old technologies and devices used for assistance during walking in CP patients.
