Study investigated the effects of four individual wheelchair components on pulmonary function in prepubertal children with cerebral palsy (CP). Participants ranging in age from 5 to 10 years were evaluated using the following wheelchair components: (1) upper extremity supports, (2) lateral trunk supports, (3) anterior pelvic belt, and (4) 30 degree posterior seat tilt. The components were evaluated in six configurations using a planar seating simulator. The Respironics Non Invasive Cardiac Output (NICO) monitor and MasterScreen Impulse Oscillometry System (IOS) measured pulmonary function parameters. Repeated measures analysis of variance was used to analyze the effect of wheelchair conditions on total airway resistance (RAW). RAW is total resistance to airflow in the tracheobronchial tree and is related to airway caliber, driving pressure, flow rate, and dynamic compliance of the lungs. Eight participants completed the protocol. RAW and minute ventilation (MV) varied with wheelchair condition. Lowest RAW was seen with two upper extremity supports or two lateral trunk supports. Differences were not significant. Study limitations and implications for future research into the benefits of wheelchair postural support components for children with CP are discussed.
