my daughter is 18months old and is having torticollis on the left side. She has been undergoing PT, but no sign of improvement. She is able to rotate her head left and right and also able to strech her head both the sides. But she tend to tilt her head left. Is PT the only treatment or any other treatment available for torticollis?

Summarized question: Is physiotherapy only treatment for torticollis in a child?
