Hypnosis Goes Mainstream
Michael Waldholz Wall Street Journal
Hypnosis, often misunderstood and
almost always controversial, is increasingly being employed in mainstream
medicine. Numerous scientific studies have emerged in recent years showing that
the hypnotized mind can exert a real and powerful effect on the body. The new
findings are leading major hospitals to try hypnosis to help relieve pain and
speed recovery in a variety of illnesses.
At the University of North
Carolina, hypnosis is transforming the treatment of irritable bowel syndrome, an
often-intractable gastro-intestinal disorder, by helping patients to use their
mind to quiet an unruly gut. Doctors at the University of Washington's regional
burn center in Seattle regularly use it to help patients alleviate excruciating
pain.
Several hospitals affiliated with Harvard Medical School are employing
hypnosis to speed up post-surgical recovery time. In one of the most persuasive
studies yet, a Harvard researcher reports that hypnosis quickened the typical
healing time of bone fractures by several weeks.
"Hypnosis may sound like magic,
but we are now producing evidence showing it can be significantly therapeutic,"
says David Spiegel, a Stanford University psychologist. "We know it works but we
don't exactly know how, though there is some science beginning to figure that
out, too."
Hypnosis can't help everyone,
many practitioners say, and some physicians reject it entirely. Even those who
are convinced of its effect say some people are more hypnotizable than others,
perhaps based on an individual's willingness to suspend logic or to simply be
open to the potential effectiveness of the process.
These days, legitimate hypnosis
is often performed by psychiatrists and psychologists though people in other
medical specialties are becoming licensed in it, too. It can involve just one
session, but often it takes several -- or listening to a tape in which a
therapist guides an individual into a trance-like state.
Whatever the form, it
is increasingly being used to help women give birth without drugs, for muting
dental pain, treating phobias and severe anxieties, for helping people lose
weight, stop smoking or even perform better in athletics or academic tests. Many
health-insurance plans, even some HMOs, now will pay for hypnosis when part of
an accepted medical treatment.
Until the last decade, many
traditional science journals regularly declined to publish hypnosis studies, and
research funding was scarce. That's changing. Dr. Spiegel, for instance, is
co-author of a widely referenced randomized trial involving 241 patients at
several prestigious medical centers. Published several years ago in the Lancet,
a respected medical journal, it found that patients hypnotized before surgery
required less pain medication, sustained fewer complications and left the
hospital faster than a similar group not given hypnosis.
Using new imaging and brain-wave
measuring tools, Helen Crawford, an experimental psychologist at Virginia
Polytechnic Institute in Blacksburg, Va., has shown that hypnosis alters brain
function, activating specific regions that control a person's ability to focus
attention. "The biological impact is very real and it can be quantified," Dr.
Crawford says.
Still, proponents say they
typically spend a great deal of time dispelling commonly held myths and
answering skeptics. Hypnosis, they say, cannot make people do or say something
against their will. Credible hypnotists don't wave a watch in front of their
clients, as portrayed in many old movies. People who enter into a so-called
hypnotic trance are not, generally, put to sleep. On the contrary, practitioners
say, they refocus their concentration to gain greater control.
Even so, the field continues to
be hurt by quacks, says Marc Oster, president of the American Society of
Clinical Hypnosis. His group, along with the Society for Clinical and
Experimental Hypnosis, publishes research studies, conducts educational seminars
for health providers and certifies those who complete course work and meet other
standards. Dr. Oster suggests that people interested in hypnosis see a health
provider licensed in a medical discipline, who is also certified by one of the
hypnosis societies -- someone who "uses hypnosis as an adjunct" to a principal
medical practice.
Researchers say that most people
unwittingly enter into hypnosis-like trances on their own in everyday life. When
reading a riveting novel or watching a film or TV, many people are experiencing
a trance-like state when they are so focused they become only vaguely aware of
nearby noise, conversation or activity. In a dream, when someone imagines
falling off a cliff and is startled awake by the sensation of falling, they are
triggering the same mental machinery that in hypnosis allows the mind to
influence the body, says Dabney Ewin, a psychiatrist at Tulane University
Medical School.
Katie Miley used self-hypnosis
taught to her by a Chicago-area psychologist to help her give birth "without
being so anxious and without pain medication." For weeks preceding the delivery
Dr. Miley, herself a psychologist, used tapes provided by the therapist to
practiced slipping into a hypnotic state. During the birth, and as suggested by
the therapist, she muted the pain by imagining the contractions "as a warm
blanket enveloping me," she says.
"It was weird," she says. "I was
aware of everyone in the room and I was interacting, but mentally my focus was
elsewhere and I just allowed the process to unfold."
Some of the clearest clinically
measured results come from using hypnosis to mute severe and chronic pain -- as
the University of Washington's regional burn-treatment center in Seattle is
doing with burn patients. Patients sent there must undergo frequent therapy to
sterilize their damaged skin, and get new grafts. They must be awake and alert
during the treatment, and even the most powerful narcotics rarely diminish the
intense pain.
David Patterson, a psychologist
at the center, induces a hypnotic trance with a typical and relatively quick
technique. Patients are told to close their eyes, breath deeply, and imagine
they are floating. Through a variety of verbal suggestions, Dr. Patterson then
helps the patient imagine themselves elsewhere, away from the treatment. "The
pain is still there, of course, but patients simply don't experience it as
before," he says.
While relieving physical pain is
one of the more common uses of hypnotism, it is also the hardest to explain. Dr.
Patterson and others report that hypnosis doesn't appear to act on the body's
natural pain-killing chemicals, the way drugs do. Instead, scientists believe,
through hypnosis a person can be trained to focus away from the pain, not on it
as most people usually do. Many athletes often unconsciously use such a
technique to play through severe pain, concentrating their attention on the game
or task ahead, instead of on their injury.
Recently, Dr. Patterson added
another tool to transport hypnotized patients to a "safer emotional
environment." He and his colleagues created a virtual reality film; patients
placed in a helmet during therapy watch a three-dimensional depiction of a
snow-covered set of mountains and canyons. By interacting with the film,
patients can feel they are suspended over a cool and calming world. Michael
"Mac" MacAneny, one of the first burn patients to use the 3-D film, says he is
certain that "it saved my life."
Early last year, Mr. MacAneny
sustained deep burns over 58 percent of his body when building a bonfire for his
sons in his backyard. A gas tank he was using suddenly exploded, enveloping him
in flames. Before Dr. Patterson began treating him, the 39-year-old Mr. MacAneny
says he dreaded his daily therapy, "freaking out" whenever the nurses came to
get him. Hypnotized and inside the 3-D virtual world, "I knew what was going on,
but I just didn't pay attention to it," he says.
Hypnosis, in some form or
another, has been used for more than 200 years. It began gaining credibility as
a medical tool in the early decades of the last century as psychiatry and
psychoanalysis began to show how the unconscious mind often rules daily life.
Its usefulness was cemented when combat physicians reported using it during
World War II for the wounded.
By 1958, as more doctors
described their experiences in the war, the American Medical Association
certified the technique as a legitimate treatment tool. Nevertheless, few
doctors employed it. But in 1996, a National Institutes of Health panel ruled
hypnosis as an effective intervention for alleviating pain from cancer and other
chronic conditions. These days, as many people accept that stress can exacerbate
illness, the potential curative power of hypnosis is becoming more acceptable,
too.
Carol Ginandes, a Harvard
psychologist at McLean Hospital in Boston, is trying to prove that "through
hypnosis, the mind can have a potent effect not only on mental well-being but
also on the acceleration of bodily healing itself."
She has co-written a study
showing ankle fractures among patients receiving a hypnotic protocol healed
weeks faster than usual and another study showing wound-healing benefits for
hypnotized breast-cancer surgery patients. Though these studies were
preliminary, Dr. Ginandes believes that hypnosis enabled her subjects to
stimulate the body's own healing mechanism to work more efficiently.
Elvira Lang, director of
interventional radiology at Beth Israel Deaconess Medical Center in Boston, has
made similar findings. She recently reported that hypnotized patients who must
remain awake during certain vascular and kidney procedures fared measurably
better than similar patients who didn't undergo hypnosis.
Still, says Dr. Lang, until very
recently, "I didn't dare use the 'H' word around here."
