In a child with right torticollis, which SCM is affected, and what is the typical head position?

• A. Left SCM, with head tilted to the left
• B. Right SCM, with head tilted to the right
• C. Left SCM, with head tilted to the right
• D. Right SCM, with head tilted to the left

Answer: (D)

In cases of right torticollis, the muscle specifically affected is the right sternocleidomastoid (SCM). This condition often results in a characteristic head position where the child tilts their head to the left side. This is due to the muscle imbalance created by the shortening or tightness of the right SCM, which causes the head to rotate away from the affected side. The typical head positioning occurs as the left SCM becomes more dominant during the head tilt, leading to this observable asymmetry. This means that the head is turned toward the side opposite the affected muscle while tilting toward the affected side. In essence, the contrast in movement and positioning emphasizes that the right SCM is not functioning optimally, leading to the described head posture. Understanding the mechanics of this condition is critical, not only for diagnosis but also for intervening appropriately through targeted therapies or interventions.
