A comprehensive review was completed on the use of adaptive seating for children with cerebral palsy from January 1990 to December 2010. Five reviews were discovered with all showing generally positive results but lacked significant evidence for "effectiveness for postural control and management, seated posture, upper extremity function, and overall clinical outcomes". The author concluded that improved strategies are needed to improve the quality of research on the use of adapted seating for children with cerebral palsy.
