Queensland MP Alex Douglas will lobby the federal government to legislate a minimum age children can be treated by chiropractors.

The member for Gaven said a recent case where a baby's neck was broken and the chiropractor involved was able to continue practicing as long as they undertook education with an “expert in the field of paediatric chiropractic” had highlighted “a failure of process” with the registration board.

The Chiropractors' Association of Australia refutes the story, but the doctor who treated the child, Melbourne paediatrician Chris Pappas, has stood by his findings.

Dr Douglas, who leads the Queensland branch of Palmer's United Party, said the report and the regulator's response showed the system was not working and needed regulation.
