To establish intrarater and interrater reliability of photographs made in a newly developed smartphone app to determine the severity of infantile skull deformation by taking a cranial photograph of an infant's head.
Using the app, 1 pediatric physical therapist and 2 pediatric physical therapy master students photographed heads of 30 infants aged up to 12 months receiving treatment for asymmetric or delayed motor development. Modified Cranial Vault Asymmetry Index and Cranial Index determined the severity of skull deformation.
Intrarater reliability was excellent both for mCVAI and CI, with an ICC(3,1) = 0.97, and ICC(3,1) = 0.98, respectively. Interrater reliability with an ICC(2,1) = 0.97 for the mCVAI, and ICC(2,1) = 0.99 for the CI was excellent too.
The reliability of the Skully Care App proved to be excellent when used by pediatric physical therapists.
