Comparison of anterior trunk supports for children with cerebral palsy

The purpose of this study was to demonstrate outcome measures of one seating component--anterior trunk supports--when used by children with cerebral palsy during a functional activity. The functional activity was pressing a single switch to activate a computer software program. Seventeen children with a mean age of 9 years were included in the study. Subjects had mild to moderate spastic or athetoid cerebral palsy. Seven had a primary diagnosis of athetoid and 10 had a primary diagnosis of spastic cerebral palsy. All subjects needed supplemental seating to maintain an upright posture. The four trunk supports tested were an anterior chest panel, a 1-inch-wide single horizontal chest strap, an anterior shoulder support, and a tray with molded chest support. Data included prehits, response time, and the length of time the subject pressed the switch. A repeated analysis of variance test was used to analyze the data. Data for athetoid and spastic cerebral palsy subject groups were analyzed separately. No statistically significant differences were found between the four trunk supports. Therefore, the choice of trunk supports for this population should be based on client preferences, ease of removal for the caregiver, cost, and aesthetics.
