A study out of Iran titled “Therapeutic touch for nausea in breast cancer patients receiving chemotherapy: Composing a treatment” was recently published in the journal Complementary Therapies in Clinical Practice. It is a great example of the Tooth Fairy science that permeates much of the research in complementary and alternative medicine. In Tooth Fairy science, researchers attempt to study a phenomenon without first determining whether it exists.
What is therapeutic touch?
Therapeutic touch (TT) is a type of energy medicine; practitioners claim to be able to:
- sense a patient’s “human energy field” with their hands,
- manipulate the energy field by moving their hands near (but not touching) a patient’s skin surface, and
- thereby improve the patient’s health.
TT was the delusional invention of a nurse and a theosophist, and it has no scientific basis. Scientists can detect and measure minute energies down to the subatomic level, but they have never detected a “human energy field.” And when TT practitioners were tested on their ability to detect such a field, they failed miserably.
“Therapeutic touch is pure vitalism, the belief in a soul or animating force,” writes Paul Ingraham, “exactly like the Force in Star Wars, and just as fanciful. Auras and life energy do not exist and cannot be felt, let alone manipulated therapeutically.”
Despite the combination of extreme implausibility and a total lack of evidence, TT is taught to nurses in many otherwise reputable institutions, and there are more than 90,000 practitioners worldwide. There is even a Therapeutic Touch International Association that claims TT is evidence-based. It is not.
TT practitioners believe they are helping patients. That belief is reinforced by seeing patients improve due to the natural course of illness, suggestion, and the “placebo” or nonspecific contextual effects of the provider/patient encounter. They allow confirmation bias to overcome scientific reality, and they do poorly-conceived research seeking further confirmation. Since the studies are designed to show that TT works rather than to ask if it works, they find evidence that is convincing to believers but not to the scientific community as a whole. (more…)
