The effect of incentive spirometer training on oromotor and pulmonary functions in children with Down's syndrome

OBJECTIVES: This study investigated the effect of incentive spirometry training on oromotor and pulmonary functions in children with Down's syndrome. METHODS: Thirty-four children with Down's syndrome were randomly divided into two groups; the children were of both sexes and aged between 6 and 12 years. Group A received only oromotor exercises, while Group B received oromotor exercises and incentive spirometry training. The pulmonary function test was performed using computerized spirometry model master screen that assessed pulmonary functions (peak expiratory flow, forced vital capacity, and forced expiratory volume in 1s), while the orofacial myofunctional evaluation with score (OMES) was used to evaluate oromotor function before and after treatment. RESULTS: The post treatment results showed significant difference in oromotor and pulmonary functions within both groups, but no significant differences were found between the two groups. CONCLUSIONS: Oromotor exercises are more effective than incentive spirometry training in improving both pulmonary and oromotor functions in children with Down's syndrome.
