Positioning for Cerebral palsy Lying:- Supine --- a pillow placed under the head, or a pillow on both sides of the head and shoulders often promotes symmetry.  In Prone :- Children are often more symmetrical in this position, but a prone wedge board is used to raise the upper torso off the floor so that they use their hands to stabilize and heads to extend.  W- Sitting:- T his position is to be avoided because of the rein forcement of the flexed, adducted and internally rotated position of hips.  Standing :-Standing prevents the Equinus deformity at the ankle. While standing the hips and knees should be extended hips slightly externally rotated and abducted knees should be straight and feet should be planti grade.
