What are the three types of Congenital Muscular Torticollis (CMT)?

The three types of Congenital Muscular Torticollis (CMT) are identified as Postural, Muscular, and SCM Nodular.

Postural CMT occurs when the infant adopts a preferred head position due to muscle tightness or imbalances. Muscular CMT involves a tightness primarily in the sternocleidomastoid (SCM) muscle, which is a key muscle responsible for head movement. SCM Nodular CMT is characterized by the formation of a fibrous mass or nodule within the SCM muscle, which can lead to head tilt and restricted movement.

Understanding these categories is essential for diagnosing and tailoring treatment for infants with CMT, as the presentation and management can vary based on the type. Each form pertains to a specific underlying condition affecting the musculature or posture of the neck, establishing a framework for clinicians to approach CMT effectively.
