Helen Alevaki, the president-elect of the Chiropractors Association of Australia, has resigned from the board three months after she was reprimanded by the regulator for making unauthorised visits to maternity hospitals.

Ms Alevaki admitted in a closed Facebook group in 2013 to paying "sneaky" visits to maternity hospitals while contributing to a discussion about practitioners' favourite adjustments.

"I get tears of gratitude EVERY SINGLE TIME," she said.

The Australian Health Practitioner Regulation Agency placed conditions on her registration in April, including that she complete further education on record-keeping practices and use of social media.

But last week the CAA accepted her resignation and declared her position vacant in a letter to members.

"Dr Alevaki's decision to step down from the Chiropractors' Association of Australia's board is in recognition that all members of the CAA must uphold the professional standards for chiropractors at all times and the reputation of the organisation," the letter said.

The departure of Ms Alevaki comes as the CAA faces competition from Chiropractic Australia, a new representative group for chiropractors that wants to focus on evidence-based medicine.

Ms Alevaki had flagged in another closed Facebook group that under her leadership the CAA would renew its interest in subluxation, a controversial theory that claims spinal manipulation can cure almost all human conditions.

Her resignation has also reinvigorated disgruntlement with the CAA board for accepting her as a candidate for president only a year after her excursions into maternity hospitals were discovered.

Joe Ierano, who ran against Ms Alevaki in the 2014 campaign, said the CAA should not condone the bad behaviour of its members.

"Helen stepped up, but it's up to the board to determine whether a candidate is suitable," said Mr Ierano, the former president of the CAA NSW.

CAA chief executive Matthew Fisher told Fairfax Media that the decision to resign had been Ms Alevaki's alone and no pressure had been placed on her by the board.

She recognised that chiropractors needed to have credentials to work in a hospital, even if the parents had given permission, he said.

"I think it's fair to say that people looking at any prospective candidacy will be asked to ensure that there's no potential breach of the constitution," Mr Fisher said.

Mr Fisher was recently embarrassed after he penned a criticism of Chiropractic Australia on the ReasonableHank medical blog and was praised by two respondents, one of whom said chiropractic "had made a real difference in my life" and the other who said Mr Fisher's insight made the person "proud to be a chiropractor".

Both respondents were later revealed to have used the same IP address as Mr Fisher.

Mr Fisher said both comments were made by legitimate sources, who had sent them into CAA's Penrith office where a staff member had posted them to the site.

The staff member had been counselled.
