Randomized Controlled Trial Clinical TrialClinical hypnosis in the alleviation of procedure-related pain in pediatric oncology patients.
This prospective controlled trial investigated the efficacy of a manual-based clinical hypnosis intervention in alleviating pain in 80 pediatric cancer patients (6-16 years of age) undergoing regular lumbar punctures. Patients were randomly assigned to 1 of 4 groups: direct hypnosis with standard medical treatment, indirect hypnosis with standard medical treatment, attention control with standard medical treatment, and standard medical treatment alone. ⋯ Therapeutic benefit degraded when patients were switched to self-hypnosis. The study indicates that hypnosis is effective in preparing pediatric oncology patients for lumbar puncture, but the presence of the therapist may be critical.

Biography Historical ArticleBenjamin Franklin and Mesmerism, revisited.
The authors revisit and update their previous historiographical note (McConkey & Perry, 1985) on Benjamin Franklin's involvement with and investigation of animal magnetism or mesmerism. They incorporate more recent literature and offer additional comment about Franklin's role in and views about mesmerism. Franklin had a higher degree of personal involvement with and a more detailed opinion of mesmerism than has been previously appreciated.

Meta AnalysisA meta-analysis of hypnotically induced analgesia: how effective is hypnosis?
Over the past two decades, hypnoanalgesia has been widely studied; however, no systematic attempts have been made to determine the average size of hypnoanalgesic effects or establish the generalizability of these effects from the laboratory to the clinic. This study examines the effectiveness of hypnosis in pain management, compares studies that evaluated hypnotic pain reduction in healthy volunteers vs. those using patient samples, compares hypnoanalgesic effects and participants' hypnotic suggestibility, and determines the effectiveness of hypnotic suggestion for pain relief relative to other nonhypnotic psychological interventions. ⋯ The results also indicated that hypnotic suggestion was equally effective in reducing both clinical and experimental pain. The overall results suggest broader application of hypnoanalgesic techniques with pain patients.

Research on hypnosis as an adjunct to cognitive-behavioral psychotherapy.
There is a growing body of research evaluating the use of hypnosis with cognitive-behavioral techniques in the treatment of psychological disorders. The central question for research is whether the addition of hypnosis enhances the efficacy of cognitive-behavioral treatments. ⋯ For cognitive-behavioral hypnotherapies to be recognized as empirically supported treatments, a number of well-designed, randomized clinical trials are necessary. Currently, the efficacy of hypnosis as an adjunctive treatment remains unresolved.

Hypnotic analgesia: 1. Somatosensory event-related potential changes to noxious stimuli and 2. Transfer learning to reduce chronic low back pain.
Fifteen adults with chronic low back pain (M = 4 years), age 18 to 43 years (M = 29 years), participated. All but one were moderately to highly hypnotizable (M = 7.87; modified 11-point Stanford Hypnotic Susceptibility Scale, Form C [Weitzenhoffer & Hilgard, 1962]), and significantly reduced pain perception following hypnotic analgesia instructions during cold-pressor pain training. In Part 1, somatosensory event-related potential correlates of noxious electrical stimulation were evaluated during attend and hypnotic analgesia (HA) conditions at anterior frontal (Fp1, Fp2), midfrontal (F3, F4), central (C3, C4), and parietal (P3, P4) regions. ⋯ Over three experimental sessions, participants reported chronic pain reduction, increased psychological well-being, and increased sleep quality. The development of "neurosignatures of pain" can influence subsequent pain experiences (Coderre, Katz, Vaccarino, & Melzack, 1993; Melzack, 1993) and may be expanded in size and easily reactivated (Flor & Birbaumer, 1994; Melzack, 1991, 1993). Therefore, hypnosis and other psychological interventions need to be introduced early as adjuncts in medical treatments for onset pain before the development of chronic pain.
