Welcome to The International Hypnosis Research Institute Web site. Our intention is to support and promote the further worldwide integration of comprehensive evidence-based research and clinical hypnotherapy with mainstream mental health, medicine, and coaching. We do so by disseminating, supporting, and conducting research, providing professional level education, advocating increased level of practitioner competency, and supporting the viability and success of clinical practitioners. Although currently over 80% of our membership is comprised of mental health practitioners, we fully recognize the role, support, involvement, and needs of those in the medical and coaching fields.

A variety of pulsed electromagnetic fields (PEMFs) have already been experimentally used, in an effort to promote wound healing. The aim of the present study was to investigate the effects of short duration PEMF on secondary healing of full thickness skin wounds in a rat model. Full thickness skin wounds, 2 by 2 cm, were surgically inflicted in two groups of male Wistar rats, 24 animals each. In the first group (experimental group - EG), the animals were placed and immobilized in a special constructed cage. Then the animals were exposed to a short duration PEMF for 20 min daily. In the second group (control group - CG), the animals were also placed and immobilized in the same cage for the same time, but not exposed to PEMF. On days 3, 6, 9, 12, 18, and 22, following the infliction of skin wounds, the size and healing progress of each wound were recorded and evaluated by means of planimetry and histological examination. According to our findings with the planimetry, there was a statistically significant acceleration of the healing rate for the first 9 days in EG, whereas a qualitative improvement of healing progress was identified by histological examination at all time points, compared to the control group.

Hypnotizability, absorption and negative cognitions as predictors of dental anxiety

The authors conducted two pilot studies that investigated the roles of hypnotizability, absorption (defined as the ability to maintain focused attention on a task or stimulus) and state versus trait anxiety as predictors of dental anxiety. One of the studies also examined the effectiveness of hypnosis in managing dental anxiety. METHODS: Participants in study 1 completed measures of hypnotizability and anxiety, viewed a video of a dental procedure either under hypnosis or not, and completed dental anxiety questionnaires. Participants in study 2 were told either that the video showed major dental work or a routine polishing. All subjects watched the video and then completed measures assessing their perceptions of the video and their anxiety. RESULTS: The authors found a positive relationship between hypnotizability and scores on the Dental Anxiety Scale (DAS) (F(1,290) = 3.45, P = .06), as well as an interaction between hypnotizability and hypnosis (F(1,290) = 6.55, P = .01). An analysis of covariance found a relationship between trait and dental anxiety (F(1,290) = 11.50; P = .001). A two-way analysis of variance found a main effect for hypnosis (F(1,290) = 3.20, P = .07). The authors found an effect for group on the DAS (F(1,228) = 3.67, P = .057), such that subjects in the negative-cognition group scored higher on the DAS. The authors found an interaction between absorption and cognition in perceptions of pain experienced by the patient in the video (F(1,228) = 3.70, P = .05) and in ratings of one's own pain level if in the same situation (F(1,228) = 4.38, P < .05). CONCLUSIONS: Hypnotizability or absorption, pre-existing anxiety and cognitions about dental procedures predict dental anxiety, and hypnosis may be helpful for some, but not all, patients. CLINICAL IMPLICATIONS: Characteristics such as hypnotizability, trait anxiety and negative cognitions predict which people develop dental anxiety and who will be more responsive to hypnosis. The authors provide suggestions for dentists treating anxious patients.
