Hypnotherapy For Pain and Other Conditions

Hypnotherapy is the use of hypnosis as a medical intervention, usually for the treatment of pain and other subjective symptoms. It remains controversial, primarily because the evidence for its efficacy is not yet compelling, but also because it is poorly understood. This situation is not helped by the fact that it is often characterized as an “alternative” therapy, a label that can “ghettoize” an otherwise legitimate treatment modality.

What Is Hypnosis?

Any meaningful discussion of hypnosis, or any other phenomenon, needs to start with a specific, and hopefully operational, definition.  If we cannot define hypnosis then it becomes impossible to meaningfully discuss it. The problem of definition plagues the science dealing with many so-called alternative therapies, such as acupuncture.  Good science requires controlling for specific variables, so that we can determine which variables are having what effects. If we don’t know which variables are part of the operational definition of a specific therapy, then we cannot conduct proper studies or interpret their results.

For example, with acupuncture, in my opinion the only meaningful definition of this procedure is the placing of thin needles into specific acupuncture points in order to elicit a specific response. Research has shown, however, that acupuncture points do not exist, that placing needles at specific points is not associated with a specific outcome, and even that sticking needles through the skin (as opposed to just poking the skin superficially) does not correlate with outcome. When these variables are isolated they do not appear to contribute anything to efficacy, therefore one might conclude that acupuncture does not work. Research into acupuncture, however, often does not adequately isolate these variables from the therapeutic ritual that surrounds acupuncture, or even mixes in other modalities, such as electrical stimulation.
