The Melbourne chiropractor accused of dangerously cracking the spine of a newborn in a viral video has been banned from treating babies.

Dr Ian Rossborough is also no longer allowed to use spinal manipulative therapy on patients aged between two and six years old and any treatment he provides to patients under 18 years must be heavily supervised.

The conditions placed on Dr Rossborough's registration to practice appeared last night and come after the Chiropractic Board of Australia was due to hold a hearing into his conduct in early June.

A video - viewed more than 1 million times - had earlier emerged on YouTube showing Dr Rossborough doing a manoeuvre on the spine of a four-day-old baby, after her parents allegedly said she had colic and reflux.
