Randomized Controlled Trial Comparative Study Clinical Trial
Can medical hypnosis accelerate post-surgical wound healing? Results of a clinical trial.
Although medical hypnosis has a long history of myriad functional applications (pain reduction, procedural preparation etc.), it has been little tested for site-specific effects on physical healing per se. In this randomized controlled trial, we compared the relative efficacy of an adjunctive hypnotic intervention, supportive attention, and usual care only on early post-surgical wound healing. Eighteen healthy women presenting consecutively for medically recommended reduction mammaplasty at an ambulatory surgery practice underwent the same surgical protocol and postoperative care following preoperative randomization (n = 6 each) to one of the three treatment conditions: usual care, 8 adjunctive supportive attention sessions, or 8 adjunctive hypnosis sessions targeting accelerated wound healing. ⋯ In addition, at both the 1 and 7 week post-surgical observation intervals, one-way analyses showed the hypnosis group to be significantly more healed than the usual care controls, p < 0.02. The mean scores of the subjective assessments of postoperative pain, incision healing and functional recovery trended similarly. Results of this preliminary trial indicate that use of a targeted hypnotic intervention can accelerate postoperative wound healing and suggest that further tests of using hypnosis to augment physical healing are warranted.

Review
Operationalizing "trance". I: Rationale and research using a psychophenomenological approach.
Despite the popularity of the term "trance" among clinicians to describe the subjective effects associated with being hypnotized, heretofore there has been no means to operationalize that definition. The authors present a rationale and psychophenomenological method to operationalize the term "trance" in terms of (a) hypnotic depth, a quantitative measure of subjective trance assessed via a pHGS (predicted Harvard Group Scale) score, derived from regression analysis, and (b) "trance typology profiles," a qualitative differentiation of empirically derived (via cluster and discriminant analyses) categories of subjective trance experiences. The authors then discuss theoretical and clinical implications of this psychophenomenological approach for developing an operational definition of the concept of trance.

On the bases of Hilgard's neodissociation theory and Spano's (1982) sociocognitive theory, volunteers stringently selected for high (N = 10) and low (N = 10) hypnotizability were exposed to a cold pressor pain test during counterbalanced conditions of waking relaxation, distraction, and hypnosis. To better discriminate between hypnosis and distraction conditions, a new distraction procedure was developed involving the memorization of a sequence of colored lights. ⋯ Quantitative electroencephalographic (EEG) findings showed significantly greater high theta (5.5-7.5 Hz) activity for highs as compared to lows at parietal (P3) and occipital (01) sites during both hypnosis and waking relaxation conditions. The findings fail to support the socio-cognitive conceptualization of hypnotic behavior while providing additional evidence supporting the neo-dissociation theory and state based theories of hypnosis in general.

Biography Historical Article
Attributions, awareness, and dissociation: in memoriam Kenneth S. Bowers, 1937-1996.
Research by Kenneth S. Bowers on posthypnotic suggestion, positive hallucinations, hypnotic analgesia, and posthypnotic amnesia is reviewed, along with his nonhypnotic research on the person-by-situation interaction and on intuition in problem solving. Bowers's intellectual style, serious curiosity, is offered as a model for hypnosis research.

Case Reports
Hypnosis as an adjunct to medical care in the management of Burger's disease: a case report.
Burger's disease is a peripheral vascular disorder characterized by constricted blood flow, ischemic pain, and necrotizing tissue processes. This report describes the application of a brief hypnosis intervention in conjunction with standard medical procedures to increase peripheral blood flow in a patient with advanced Burger's disease. Using suggestions for foot warming and increased blood flow, substantial increases in surface foot temperature were obtained prior to and following an epidural sympathectomy. ⋯ Treatment gains were maintained through discharge and at two month follow up. The results suggest that hypnosis may serve as a parsimonious, yet efficacious adjunct to standard medical care in the management of reduced peripheral blood flow in patients with Burger's disease. Further, it illustrates the feasibility of hypnosis as an adjunct treatment in busy, inpatient hospital settings.
