As thetri in triplegia implies, for a child with this form of Cerebral Palsy, three limbs are involved. The most common pattern is for both legs and one arm to be affected. This is sometimes thought of as hemiplegia overlapping with diplegia and because of the primary motor dysfunction being that of the legs, the guidelines and recommendations pertaining to diplegia may offer the most useful information.
If all three limbs are severely impaired, resources for children with quadriplegia would probably be the most beneficial. This form of cerebral palsy is thought of as quadriplegia with less severe involvement of one of the arms.
