Abstract
Background Fibrodysplasia ossificans progressiva (FOP) is a catastrophic genetic disorder of progressive heterotopic ossification (HO). Assessment of functional mobility in FOP will be essential to support clinical trials of investigational agents. Results Of necessity, we developed a simple, rapidly-administered, cumulative analogue joint involvement scale (CAJIS) for FOP based on assessments in 144 individuals worldwide with classic FOP. Conclusions CAJIS scores correlated with patient age, activities of daily living, and ambulatory function with excellent inter-rater variability. We show here that the CAJIS score provides an accurate and reproducible snapshot of total body and regional mobility burden in FOP.
