Whilst it is now generally accepted that both Hypnosis and acupuncture can alleviate pain, the precise mechanism that triggers the analgesic response remains unclear for both treatments.
It was for this reason that researchers at the Department of Anaesthesiology, Hopital Cantonal Universitaire of Geneva, Switzerland recently investigated and compared the analgesic effect of hypnosis and acupuncture .
Experimental pain was induced by cold pressor test (CPT) in eight male volunteers. The analgesic effects of hypnosis and acupuncture were assessed before and after double-blind administration of a placebo or naloxone, in a prospective, cross-over study.
The results showed that pain intensity was significantly lower with hypnotherapy as compared with acupuncture, and the pain scores did not differ significantly when naloxone or placebo was administered. The researchers concluded that both hypnosis and acupuncture can or AA nor by naloxone or placebo administration.
