Improvement of functional sitting position for children with cerebral palsy.

Twenty-three children with cerebral palsy were photographed and video-filmed in six different sitting positions--including a hypothetical functional position--and the video-films and photographs were analysed. It was found that pathological movements were minimised and postural control and arm and hand function best when the child was sitting in a forward-tipped seat, with a firm backrest supporting the pelvis, arms supported against a table and feet permitted to move backward.
