Background: Congenital muscular torticollis (CMT) is a postural deformity evident shortly after birth, typically characterized by lateral flexion/side bending of the head to one side and cervical rotation/head turning to the opposite side due to unilateral shortening of the sternocleidomastoid muscle (SCM); it may be accompanied by other neurological or musculoskeletal conditions. Infants with CMT should be referred to physical therapists to treat these postural asymmetries as soon as they are identified.

Infants with CMT are frequently referred to physical therapists (PTs) to treat their asymmetries. This evidence-based clinical practice guideline (CPG) provides guidance on which infants should be monitored, treated, and/or referred, and when and what PTs should treat. Based upon critical appraisal of literature and expert opinion, 16 action statements for screening, examination, intervention, and follow-up are linked with explicit levels of evidence. The CPG addresses referral, screening, examination and evaluation, prognosis, first-choice and supplemental interventions, consultation, discharge, follow-up, suggestions for implementation and compliance audits, flow sheets for referral paths and classification of CMT severity, and research recommendations.
