Conversion therapy has been banned last week in Canada. These therapies – also known as sexual orientation change effort (SOCE), reparative therapy, reintegrative therapy, reorientation therapy, ex-gay therapy, and gay cure – rely on the assumption that sexual orientation can be changed, an idea long discredited by major medical associations in the US, the UK, France, and elsewhere. The new law makes “providing, promoting, or advertising conversion therapy” a criminal offense. It will also be an offense to profit from the provision of conversion therapy. In addition, the bill states a person cannot remove a “child from Canada with the intention that the child undergo conversion therapy outside Canada.” Prime Minister Justin Trudeau hailed the law’s Royal Assent: “It’s official: Our government’s legislation banning the despicable and degrading practice of conversion therapy has received Royal Assent — meaning it is now law.”

Conversion therapy is the attempt to change an individual’s sexual or gender identity by psychological, medical, or surgical interventions. Often, informed consent is insufficient or lacking. In conventional medicine, numerous treatments have been tried for this purpose, some of them dangerous and all of them ineffective. In alternative medicine, approaches that have been advocated include:

  • Homeopathy (see below),
  • Hypnotherapy,
  • Spiritual healing,
  • Prayer,
  • Eye Movement Desensitization,
  • Rebirthing,
  • and others.
Survey data imply that conversion therapy is still disturbingly popular, often leads to undesirable outcomes, and is most frequently practiced by:
  • Faith-based organizations or leaders
  • Licensed healthcare professionals
  • Unlicensed healthcare professionals

As previously reported, the German ‘Association of Catholic Doctors’ claimed that homeopathic remedies can cure homosexuality. Specifically, they advised that ‘…the working group ‘HOMEOPATHY’ of the Association notes homeopathic therapy options for homosexual tendencies…repertories contain special rubrics pointing to characteristic signs of homosexual behavior, including sexual peculiarities such as anal intercourse. And a homeopathic remedy called ‘Dr. Reckeweg R20 Glandular Drops for Women’ was claimed to treat “lesbian tendencies.” The product is “derived and potentised from fetal tissues.”

Several countries are now in the process of banning conversion therapy. France has already banned it and so has Germany. The UK government intends to introduce a legislative ban on the practice of conversion therapy. The consultation on how to best do this is open until 4 February 2022.

We all know, I think, that chronic low back pain (CLBP) is common and causes significant suffering in individuals as well as cost to society. Many treatments are on offer but, as we have seen repeatedly on this blog, not one is convincingly effective and some, like chiropractic, is associated with considerable risks.

Enthusiasts claim that hypnotherapy works well, but too little is known about the minimum dose needed to produce meaningful benefits, the roles of home practice and hypnotizability on outcome, or the maintenance of treatment benefits beyond 3 months. A new trial was aimed at addressing these issues.

One hundred veterans with CLBP participated in a randomized, four parallel group study. The groups were (1) an eight-session self-hypnosis training intervention without audio recordings for home practice; (2) an eight-session self-hypnosis training intervention with recordings; (3) a two-session self-hypnosis training intervention with recordings and brief weekly reminder telephone calls; and (4) an eight-session active (biofeedback) control intervention.

Participants in all four groups reported significant pre- to post-treatment improvements in pain intensity, pain interference and sleep quality. The three hypnotherapy groups combined reported significantly more pain intensity reduction than the control group. There was no significant difference among the three hypnotherapy groups. Over half of the participants who received hypnotherapy reported clinically meaningful (≥30%) reductions in pain intensity, and they maintained these benefits for at least 6 months after treatment. Neither hypnotizability nor amount of home practice was associated significantly with treatment outcome.

The authors conclude that two sessions of self-hypnosis training with audio recordings for home practice may be as effective as eight sessions of hypnosis treatment. If replicated in other patient samples, the findings have important implications for the application of hypnosis treatment for chronic pain management.

Even though this trial has several important limitations, I do agree with the authors: these results would be worth an independent replication – not least because self-hypnosis is cheap and does not carry great risks. What would be interesting, in my view, are studies that compare several alternative LBP therapies (e.g. chiropractic, osteopathy, acupuncture, massage, various form of exercise and hypnotherapy) in terms of cost, risks, long-term effectiveness and patients’ preference. I somehow feel that the results of such comparative trials might overturn the often issued recommendations for spinal manipulation, i.e. chiropractic or osteopathy.
