Journal of Pediatric Orthopaedics , 05/17/2012
Seok Park M et al. – The sports/physical function domain in Pediatric Outcomes Data Collection Instrument (PODCI) generally satisfies the requirements of Rasch item response theory and is an appropriate measure of the function in cerebral palsy. Although some individual items do not fit well, the PODCI can be improved by eliminating the redundant items and by adding more difficult tasks to fill in the gaps.
