The children with cerebral palsy have a wide range of difficulties in walking, speaking and swallowing from the brain damage. Successful treatment of cerebral palsy is needed team work from variety of professionals. These professionals and numerous others worked together as a team with child or adult to help the individual achieved as much independence and competence as possible. Especially physical and occupational therapists help to develop necessary skills to the activities of daily living. Speech pathologists help feeding and speech dysfunction. The treatment for the children with cerebral palsy is very important the normal postural mechanic. Most of all, trunk and head control is most important to the treatment. This paper focused on three inquiries concerning the articulatory training program on the trunk and head control for the children with cerebral palsy as follow: 1. Can the trunk and head control on the respiratory and articulatory training program improve articulation function for the children with cerebral palsy? 2. Can the trunk and head control on the respiratory and articulatory training program increase maximum phonation time(MPT) when the children with cerebral palsy produce vowel? 3. Can the trunk and head control on the respiratory and articulatory training program improve the correctly pronounce vowel for the children with cerebral palsy? In order to perform this research, four children participated as test subjects. Two children were athetoid type and the other were spastic type. This program was consisted of two programs. One is the respiratory and articulatory training program and the other is the trunk and head control program. During this study, each subject had tests on pre-therapy(3 sessions over one week period), therapy and post-therapy. Each session was 40 minutes and the total of 30 sessions were given at a rate of treatment program. The findings of this research project were as follows: First, the trunk and head control on the respiratory and articulatory training program improved articulation function for the children with cerebral palsy. Second, the trunk and head control on the respiratory and articulatory training program increase maximum phonation time(MPT) when the children with cerebral palsy produced vowel. Third, the trunk and head control on the respiratory and articulatory training program improve the correctly pronounce vowel for the children with cerebral palsy.
