Muscular Torticollis is characterized by unilateral tightness of the sternocleidomastoid (SCM) muscle. This condition often leads to a noticeable tilt of the head toward the side of the affected muscle, accompanied by rotation of the head toward the opposite side. The unilateral tightness causes asymmetrical positioning of the head and neck, which is a hallmark feature of this condition.

Understanding that bilateral SCM tightness would generally result in a more symmetrical head position can clarify why this aspect does not define Muscular Torticollis. Additionally, the absence of muscle tightness combined with head tilt or symmetrical muscle tone would not align with the muscular involvement seen in this condition. The defining characteristic remains the specific tightness of one SCM muscle, leading to the distinctive head posture observed in affected individuals.
