The ‘Free University Amsterdam’ appoints a chiropractor as Professor!

Guest post by Catherine de Jong

Academic circles have reacted with surprise to the announcement on 12 November of the appointment of chiropractor Sidney Rubinstein as endowed professor at the Vrije Universiteit Amsterdam. The website of the Dutch Chiropractors Association (NCA)  states:

“On 1 August 2024, Mr. Sidney Rubinstein was appointed professor by special appointment at the chair “Optimizing Management of Musculoskeletal Health” at the Vrije Universiteit in Amsterdam. In addition to his work as a chiropractor in his own practice, Rubinstein has been working at the Vrije Universiteit for a long time. In addition to treating patients, he has always focused on research and development within chiropractic and musculoskeletal (MSK) disorders.”

Chiropractic is an alternative method of treatment. There is no scientific evidence for clinically relevant positive treatment outcomes. For that reason, chiropractic is not mentioned as a treatment option in the guidelines of general practitioners and medical specialists in the Netherlands. Both the profession and the education are not recognized in the Netherlands. On the website of the NVAO (Dutch-Flemish Academic Organization, www.nvao.net), chiropractic does not appear as an accredited program. There is now plenty of research, especially case reports, on the damage that treatment by a chiropractor can cause, such as cerebral infarctions due to arterial dissection of carotid arteries due to cracking of the neck by chiropractors.

On June 20, 2008, the website of Medisch Contact (magazine of KNMG, Dutch Society of Medical Doctors) stated: “First Dutch chiropractor gets his PhD: Sidney Rubinstein will be the first chiropractor in the Netherlands to obtain a PhD today. Rubinstein states that most of the side effects of chiropractic are harmless and temporary.”

This dissertation, for which Sidney Rubinstein obtained his doctorate at VU Amsterdam, was substandard and was criticized in a letter sent to the same journal. The subsequent correspondence with, among others, the supervisor can be read here. In short, a dissertation that VU Amsterdam cannot be proud of.

The Cochrane database contains two reviews published by Rubinstein on chiropractic, or Spinal Manipulative Therapy (SMT) for acute and chronic back pain, respectively. The conclusion was the same in both cases: In summary, SMT appears to be no better or worse than other existing therapies for patients with acute/chronic low‐back pain. In a 2013 update (Spinal manipulative therapy for acute low back pain: an update of the Cochrane review. Spine 2013; 38(3): E158-77), Rubinstein comes to the same conclusion: SMT is no more effective for acute low back pain than inert interventions, sham SMT or as adjunct therapy. SMT also seems to be no better than other recommended therapies. Rubinstein himself has concluded years ago that chiropractic or SMT has no greater effect than other treatments (like standard physiotherapy), but still it needs to be researched again and again?

At the end of the news item on the NCA’s website, the truth is revealed: the NCA subsidizes half of the chair! The members of this organization (there are now more than 500 chiropractors in the Netherlands) have diligently raised the money for this chair. Since its foundation in 1896 by the grocer/magnetizer D.D. Palmer, chiropractic has had every chance to prove its usefulness, but it has not succeeded. That Rubinstein can change that situation is, of course, extremely unlikely.

This appointment is therefore in fact a political publicity stunt for a still pointless alternative treatment. It will do both the practice of Sidney Rubinstein and that of other chiropractors a lot of good that there is now a professor of chiropractic in the Netherlands.

The other half of the chair is paid for by the university. This means that public money that could have been better spent is now going to be wasted on research into an alternative treatment that we already know is useless, by a researcher who has already shown that there is no added value of treatment by a chiropractor.

A substandard dissertation and a purchased chair, but Sidney Rubinstein can call himself a professor. With the appointment of chiropractor Sidney Rubinstein as endowed professor at VU Amsterdam, the university is jeopardizing its good name and contributing to the unjustified elevation of Sidney Rubenstein’s status and his pointless method of treatment, chiropractic.
Can this appointment really be reconciled with the scientific norms and values that VU Amsterdam wants to uphold?
