A video footage showing a Melbourne chiropractor manipulating a four-day-old baby’s back by making it crack to treat baby colic has been widely condemned by doctors. Victoria’s health minister Jill Hennessy, said the video has prompted her to call for an urgent crackdown on such rogue operators.

The video that has received more than one million views showed a Melbourne chiropractor holding the crying infant in his hands while he was talking to her parents and then suddenly cracked her back that made a loud sound. The parents brought the baby to the chiropractor because the child was crying regularly at night that disturbed her sleep. The so-called treatment of the baby was successful according to the chiropractor.

The chiropractor, Dr. Ian Rossborough, posted other videos of his unconventional ways of treatment of a range of ailments on his YouTube channel. This particular video has caused a great level of concerns among doctors.

“I can understand doctors are outraged by the extremely distressing image of a four-day-old baby having its spine cracked,” The Guardian quoted Hennessy as saying on Friday, in response to the video. “That’s why I have requested the Chiropractic Board of Australia and the Australian Health Practitioner Regulation Agency to take urgent action to crack down on rogue chiropractors in the interests of children’s and babies’ safety.”

The chiropractors treat ailments like colic, autism and attention deficit hyperactive disorder in children by manipulating their backs. They even allegedly discourage parents from vaccinating their children. “When you see the patients returned with these children, they always report that the child is just so much more comfortable, they sleep so much better, they eat so much better,” the chiropractor could be heard saying in the video.

According to Dr. Frank Jones, director of The Royal Australian College of General Practitioners, the method of treatment is cruel. “Well, I think that this is an unnecessary and seemingly almost cruel process that there is actually no evidence to support,” the Mail Online quoted Jones as saying. “Why would you ever ever do that?”

He added that “It should not be advertised, it should not be practiced.” He also noted that so far there is no scientific evidence that manipulating the spine can treat colic or asthma.
