Congenital muscular torticollis (CMT) is a common musculoskeletal diagnosis in infants. Muscular CMT with and without a sternocleidomastoid mass are the two most restrictive types of CMT resulting in postural abnormalities and impairments in range of motion (ROM) and strength. Postural preference is the third type of CMT that does not limit ROM but results in a visible head tilt. Physical therapy (PT) is the first line, conservative intervention to resolve signs of CMT, yet not all infants complete a course of treatment. The purposes of this dissertation were first to describe demographic patterns, baseline clinical characteristics, and PT recommendations for 3 groups of infants with CMT when discharge criteria were (1) met following direct PT; (2) unmet following direct PT; (3) unmet following home program instruction. The second purpose was to examine cervical range range and strength in infants with CMT when discharge criteria were met or unmet at least 6 months after initial PT examination.
