BUFFALO, N.Y. — Hypnosis can help alleviate the pain and suffering experienced by women being treated for breast cancer, according to a study by a University at Buffalo School of Social Work professor.

The randomized trial measured pain and suffering, frequency of pain and degree of constant pain among 124 women with metastatic breast cancer, according to Lisa D. Butler, associate professor in UB’s School of Social Work, a faculty member in the Buffalo Center for Social Research and first author of the study.

Researchers recorded levels of pain at four-month intervals for a year. Women who were assigned to the treatment group received group psychotherapy, as well as instruction and practice in hypnosis to moderate their pain symptoms. They reported “significantly less increase in the intensity of pain and suffering over time,” compared with a control group, who did not receive the group psychotherapy intervention.

However, those using hypnosis reported no significant reduction in the frequency or constancy of pain episodes.

“The results of this study suggest that the experience of pain and suffering for patients with metastatic breast cancer can be successfully reduced with an intervention that includes hypnosis in a group therapy setting,” according to Butler. “These results augment the growing literature supporting the use of hypnosis as an adjunctive treatment for medical patients experiencing pain.”

The study was published last year in an issue of the American Psychological Association journal Health Psychology.

The researchers also found that, within the treatment group, those patients who could be hypnotized more easily — a group the researchers said demonstrated “high hypnotizability” — reported greater benefits from hypnosis. These patients used hypnosis more overall, including outside of the group sessions, and in some cases used it to address other symptoms related to their cancer.

“These results suggest that although hypnosis is not at present standard practice for treating a wide range of symptoms that trouble cancer patients, it is worth examining that potential,” Butler says. “Together, these findings suggest that there may be a number of benefits to the use of hypnosis in cancer care including, but not necessarily limited to, its more traditional application for pain control.”

Butler joined the UB faculty in January 2009, after doing research at Stanford University’s School of Medicine. She was hired at UB to strengthen the university’s research focus on “extreme events” as part of the UB 2020 strategic planning initiative. She recently published a nationally recognized study on how some people living through an extremely traumatic event – including the 9/11 terrorist attacks — have the ability to recover or even grow in personal and interpersonal functioning.

The University at Buffalo is a premier research-intensive public university, a flagship institution in the State University of New York system and its largest and most comprehensive campus. UB’s more than 28,000 students pursue their academic interests through more than 300 undergraduate, graduate and professional degree programs. Founded in 1846, the University at Buffalo is a member of the Association of American Universities.

Hypnosis for Weight Loss: Does It Work?

Yes, hypnosis for weight loss does work!

In a 9-week study of two weight management groups (one using hypnosis and one not using hypnosis), the hypnosis group continued to get results in the two-year follow-up, while the non-hypnosis group showed no further results (Journal of Clinical Psychology, 1985).

In a study of 60 women separated into hypnosis versus non-hypnosis groups, the groups using hypnosis lost an average of 17 pounds, while the non-hypnosis group lost an average of only .5 pounds (Journal of Consulting and Clinical Psychology, 1986).

In a meta-analysis, comparing the results of adding hypnosis to weight loss treatment across multiple studies showed that adding hypnosis increased weight loss by an average of 97% during treatment, and even more importantly increased the effectiveness POST TREATMENT by over 146%. This shows that hypnosis works even better over time (Journal of Consulting and Clinical Psychology, 1996).

How Effective Is Hypnosis in Relieving Pain?

Hypnosis is a state of altered awareness in which we can become absorbed in more relaxing thoughts, ideas, images and feelings, and more easily distracted from negative or painful ones. Many people who benefit from hypnosis respond well to suggestions about feeling less pain, more comfort, increased energy, better sleep, and having rapid healing  outcomes. Only about 10-20% of the general population does not receive good results from hypnosis; this group may benefit more from biofeedback and other methods.

There are many published, well-controlled research studies that focus on the use of hypnosis with surgery.  In a recent review of 18 of these studies1, the overall result was that most patients treated with hypnosis have moderate to significantly better surgical outcomes including reports of less pain, use of fewer pain medications, and faster  recovery. For example, medical hypnosis for orthopedic hand surgery, which is typically very painful, showed benefits  that included significantly less post-surgery pain and anxiety, and fewer complications2. In a different study, 339  patients undergoing thyroid and parathyroid neck surgery, were divided into two groups. One group had hypnosis and an intravenous medication that kept them conscious while the other group was given general anesthesia. The hypnosis group had less pain, used fewer pain medications, and had shorter hospital stays3. In a similar study of 241 patients who underwent invasive medical procedures4, those who received pre-surgical instruction in self-hypnosis had less pain and anxiety than those who did not receive self-hypnosis instruction. In summary, a year 2000 review of published articles in the field of hypnosis concluded that “the research to date generally substantiates the claim that hypnotic procedures can ameliorate many psychological and medical conditions.” 5

There has also been evidence that hypnosis may affect the way that pain is processed in the brain. In a recent study, volunteers who plunged their hands into hot water were measured by a PET scan. Later, they were hypnotized and told that the water would not seem as painfully hot. During hypnosis, the PET scan was re-administered, showing significantly less activation in the anterior cingulate cortex, the part of the brain that is involved in expanding feelings of  emotional distress and can also influence the inhibition of pain. On the other hand, the PET scan data obtained during hypnosis showed no decrease in activation in the somatosensory cortex region which is involved in processing the  sensation of pain.6 These results suggest that even though the brain may continue to register the sensation of pain, hypnosis seems to help patients shift their experience of pain away from distress and suffering.

Hypnotic intervention has also been used successfully with many types of specific pain. In the treatment of burn patients, hypnosis has been used to reduce the pain associated with debridement (the scrubbing away of burned tissue to  give new tissue a chance to grow) and wound cleaning, to modulate anxiety related to burn procedures, and to enhance  coping styles such as repression and intellectualizing.7 With cancer patients, hypnotic suggestion helps to reduce the suffering related to many painful procedures such as the administration of chemotherapy and treatment-related throat pain and nausea. Hypnosis can also help to reduce the frequency and intensity of migraine headaches, and to relieve tension headaches8. In the area of dentistry, hypnosis is used to reduce orofacial pain held in the muscles and jaw,  and pain, distress, and anxiety related to specific dental procedures such as root canals and extractions. Other significantly effective applications of hypnosis include reduction of anxiety and physical pain related to invasive  medical procedures including endoscopies, intubation, catheter discomfort, and blood transfusions.
