Can massage help to improve torticollis?

Not really: Only real help comes from Botox injections.

Maybe: If you are referring to congenital muscular torticollis in an infant then massage and stretching can be helpful.

It Might: It might, particularly thru relief of the pain and muscle spasm.

No: Massage may help muscle pain due to the spasm of the torticollis, but it won't make the torticollis any better or worse. Torticollis happens in the brain, but massaging the brain directly is difficult and tends to be counterproductive.
