Clinical Determinants of the Outcome of Manual Stretching in the Treatment of Congenital Muscular Torticollis in Infants

This large prospective study demonstrated that controlled manual stretching is safe and effective in the treatment of congenital muscular torticollis when a patient is seen before the age of one year. The most important factors that predict the outcome of manual stretching are the clinical group, the initial deficit in rotation of the neck, and the age of the patient at presentation. Surgical treatment is indicated when a patient has undergone at least six months of controlled manual stretching and has residual head tilt, deficits of passive rotation and lateral bending of the neck of >15 degrees, a tight muscular band or tumor, and a poor outcome according to our special assessment chart.
