Biofeedback
Protocol for Migraines &
Some Patients with IBS
Consider This Therapy For:
This specialized type of training allows people to gain control over
physiological reactions that are ordinarily unconscious and automatic.
Malfunctions in these automatic responses contribute to a wide variety of
medical problems. In study after study, biofeedback has shown the ability
to help bring such counterproductive reactions back into line, providing
significant relief for many of the people who try it.
Although it's not a sure cure, biofeedback helps many
people with chronic pain, including the pain of arthritis, muscle spasms,
and headache (both migraine and tension headache). It can reduce tension
and anxiety, combat chronic insomnia and fatigue, alleviate depression,
reduce hyperactivity and attention deficit disorder, and even help
overcome alcoholism and drug addiction. Some people have found it helpful
for controlling high blood pressure or an abnormal heart rate. It's also
useful for retraining, reconditioning, and strengthening muscles after an
accident or surgery, restoring loss of control due to pain or nerve
damage, and overcoming urinary (or bowel) incontinence.
For asthmatics, biofeedback offers the possibility of
controlling bronchial spasms and reducing the severity of attacks. Many
victims of Raynaud's disease (periodic loss of circulation in the fingers)
have been able to rectify the problem through biofeedback. The technique
has helped others deal with digestive disorders such as ulcers, irritable
bowel syndrome, acidity, dysfunction of the esophagus, and difficulty
swallowing.
Biofeedback is under study as a potential aid in the
treatment of a number of other ailments as well, although results are more
mixed. It may help relax the muscles in temporomandibular joint syndrome
(TMJ). It appears to reduce the severity and frequency of seizures in some
(though not all) epileptics. It can help ease the symptoms of chronic
fatigue syndrome. It has even been tried as a remedy for chronic
constipation, motion sickness, and the uncontrollable tics and compulsions
of Tourette syndrome.
How the Treatments Are Done
Biofeedback is not a passive treatment. It requires your intensive
participation as you learn to control such normally involuntary
("autonomic") functions as heart rate, blood pressure, brain waves, skin
temperature, muscle tension, breathing, and digestion.
At your first session, you'll be asked a few questions
about your own health and that of family members. The biofeedback
therapist will then apply sensors to various points on your body. The
location depends on the problem that needs treatment. If you have
migraines, sleep problems, and mood disorders, for example, the electrodes
are often attached to your scalp; to treat heart problems and muscle
tension, they will be placed on your skin. Other possible sites include
the hands, feet, or fingers.
The sensors are connected to a computer, a polygraph, or
another piece of monitoring equipment that provides instant feedback to
you on the function you're trying to control, such as the tension in a
particular set of involuntary muscles or circulation to a specific part of
the body. Some biofeedback machines signal changes graphically on a
computer display, others beep, buzz, or blink to indicate the strength or
level of the function you're targeting.
The therapist will teach you mental or physical
exercises that can help you affect the function that's causing a problem.
You can easily gauge your success by noting any changes in the intensity,
volume, or speed of the signals from the machine. Gradually, you'll learn
to associate successful thoughts and actions with the desired change in
your involuntary responses.
Once you've thoroughly learned an effective pattern of
actions, you'll be able to assert control without the aid of the feedback
device.
Among the feedback instruments you're most likely to
encounter are the following:
Electromyographs (EMGs) measure muscle tension.
Therapists use them to relieve muscle stiffness, treat incontinence, and
recondition injured muscles.
Skin Temperature Gauges show changes in the
amount of heat given off by the skin, a measurement that indicates any
change in blood flow. These gauges are used in the treatment of Raynaud's
disease, high blood pressure, anxiety, and migraines.
Galvanic Skin Response Sensors (GSRs) use the
amount of sweat you produce under stress to measure the conductivity of
your skin. They are often used to reduce anxiety.
Electroencephalographs (EEGs) measure brain-wave
activity. Conditions that may benefit from training on these machines
include attention deficit/hyperactivity disorder, tooth grinding, head
injuries, and depression (including bipolar depression and seasonal
affective disorder).
Electrocardiographs (ECGs) monitor the heart rate
and may be useful in relieving an overly rapid heartbeat and controlling
high blood pressure.
Respiration feedback devices concentrate on the
rate, rhythm, and type of breathing to help lessen symptoms of asthma,
anxiety, and hyperventilation and promote relaxation.
Along with biofeedback training, the therapist may also
give you instruction in deep breathing, meditation, visualization, and
muscle relaxation--all of which may aid in relieving stress-related
symptoms.
Treatment Time: Sessions usually last between 30
minutes and 1 hour.
Treatment Frequency: In most cases, people can
learn to raise or lower their heart rate, relax specific muscles, lower
blood pressure, and control other functions in 8 to 10 sessions. Some
problems, such as attention deficit/hyperactivity disorder, take
longer--sometimes up to 40 sessions.
Depending on the severity of the problem and the
technique used, therapists suggest you attend 1 to 5 sessions per
week.
What the Treatment Hopes to Accomplish
Biofeedback is a "mind over matter" form of therapy that has only recently
begun to filter into mainstream medicine. Although ancient Greek, Chinese,
and Indian healers were convinced that the mind could influence the body,
either causing illness or curing disease, the concept fell into disrepute
as Western medicine began to discover the infectious agents and chemical
malfunctions that lie at the root of so many familiar ailments. It was
only when modern instrumentation made it possible to measure subtle
changes in unconscious physical reactions that medicine once more turned
its attention to the mind-body connection.
Although biofeedback promises to remedy certain ailments
through disciplined mental effort, it has nothing in common with other
forms of mind-body therapy such as meditation and yoga. It does not rely
on maintenance of some sort of theoretical balance or harmony in order to
achieve its effects. Instead, it seeks control over specific, measurable
physiological reactions that have somehow gone awry. As such, it can prove
especially useful for any disorder caused or aggravated by involuntary
muscular tension or tightening. Like other forms of mind-body therapy,
it's entirely useless for fighting infections, curing cancer, relieving
allergies, or healing injuries.
Who Should Avoid This Therapy?
If you use a pacemaker or have a severe heart disorder, check with your
doctor before using a biofeedback device that measures your perspiration
output. These machines use a small amount of electricity to produce
readings, and, even though no problems have been reported to date, there
is a chance that they may affect your pacemaker or damage your heart.
What Side Effects May Occur?
Like other mind-body forms of therapy, biofeedback is notably free of side
effects. Indeed, it's often turned to by people seeking a respite from the
side effects of conventional medicines.
How to Choose a Therapist
Select a biofeedback therapist with training in psychology and, ideally,
physiology. He or she should be certified by the Biofeedback Certification
Institute of America. Directories of biofeedback practitioners are
available from the Institute.
You may also check with a biofeedback association in a
major city near you, ask your physician for a recommendation, or (as a
last resort) find a therapist in the Yellow Pages.
When Should Treatment Stop?
If you see no improvement in 10 to 20 sessions, or if your problem
worsens, you're probably one of the people for whom biofeedback doesn't
work. You should discontinue the training and ask your doctor about other
alternatives.
See a Conventional Doctor If...
Although biofeedback is harmless--and can often be helpful--it is not a
substitute for regular visits to the doctor if you have a serious chronic
condition such as diabetes, epilepsy, heart disease, or high blood
pressure. For such problems, failure to continue conventional care can be
more dangerous than any alternative you care to try.
Likewise, if you try biofeedback to help ease
depression, do not suddenly drop other forms of treatment. Continue to see
your doctor. Eventually, he may be able to reduce the dosage of your
antidepressant medication as you continue your training.
Remember, too, that if your biofeedback techniques
suddenly fail to work, you may be facing a new medical problem for which
biofeedback is ineffective. At such times, it's wise to see your doctor
for a thorough diagnosis.
