Seating orientations and upper extremity function in children with cerebral palsy.
This study was conducted to determine the effect of body orientation on upper extremity function in children and adolescents with cerebral palsy. Thirteen children between ages 8 and 16 and diagnosed as having spastic or athetoid cerebral palsy were placed randomly in different seating orientations (30 degrees, 15 degrees, and 0 degrees of posterior inclination and 15 degrees of anterior inclination). In each seating position, the subject performed an upper extremity activity on cue. The tests were repeated in reverse sequence. Mean performance times were different at all seating orientations for both types of subjects. Performance time was lowest at the 0-degree orientation during the retest for the subjects with spasticity and highest at 15-degree anterior inclination during the retest for the subjects with athetosis. The results of this study show that orientation of the body in space affects upper extremity function and emphasizes the importance of positioning for maximizing upper extremity function.
