The PEDI\u2010CAT was most informative for type III SMA, with ability levels distributed close to 0.0 logits in both domains. It was less informative for types I and II SMA, especially for mobility skills. Item and person abilities were not distributed evenly across all types. <jats:italic>Conclusions:<\/jats:italic> The PEDI\u2010CAT may be used to measure functional performance in SMA, but additional
