"For
most of this century," says William Tiller, Ph.D., of Stanford
University, "science and medicines have seen health as being
dependent upon the balance of body chemistry and the functioning
of physical structures. However, attempts to treat illnesses and
imbalances chemically often lead to unwanted side-effects or the
body becoming insensitive to the chemicals."
This
fact has led many physicians and health professionals to look beyond
conventional drug-based therapies to the field of energy medicine.
Many of the most sophisticated diagnostic systems used today is
conventional medicine, such as the ECG (electrocardiogram), EEG
(electroencephalogram), EMG (electromyelogram), and MRI (magnetic
resonance imaging), employ the principles of energy medicine. Energy
medicine, or bioenergetic medicine as it is sometimes called, refers
to therapies that use an energy field-electrical, magnetic, sonic,
acoustic, microwave, infrared-to screen for or treat health conditions
by detecting imbalances in the body's energy fields and then correcting
them.
The
detection of energy level imbalances in the body is essential for
providing an early warning system for potential disruptions in chemical
balance that may lead to disease. Balance can then be restored using
holistic therapies, or with treatment devices that rebalance the
energy levels of the various fields before the chemical or structural
disturbances can occur.
Uses
Electricity
plays a prominent role in modern medicine. The charged paddles used
to jolt the heart back into action are a common sight in emergency
rooms everywhere. Electroencephalograms (EEGs) record electrical
brain waves and electrocardiograms (EKGs) read the rhythms of the
heart. Electrical devices ranging from the common x-ray to the gigantic
MRI (magnetic resonance imaging) machine routinely give us an accurate
diagnosis. The contraptions and procedures promoted under the rubric
of 'energy medicine' are, however, an entirely different matter.
They are either extremely controversial or totally unproven. Some
are simply electrified versions of other alternative therapies such
as acupuncture. Others are the last remnants of a fascination with
'black box' cures that extends form the dawn of the electrical age
through the present. Of all the electrical therapies currently available,
transcutaneous electrical nerve stimulation (TENS) is the
closest to adoption in the mainstream. It can be used for any type
of localized physical pain, although it is most commonly advocated
for arthritis, sciatica, neuralgia and chronic back pain. It is
sometimes used after knee, hip, or lower back surgery (usually in
combination with other analgesic treatments). And it has also been
used for dental pain, jaw muscle pain, cancer pain, angina pectoris,
menstrual pain, migraine, carpal tunnel syndrome, repetitive strain
injuries, pain from nerve damage, musculoskeletal trauma and the
pain of shingles. All other forms of energy therapy remain either
untested or unverified. Among the leading examples, electroacupuncture
and auricular acupuncture (acupuncture limited to the ear)
are advocated for treatment of disorders throughout the body. Similarly,
a device called the Mora delivers electromagnetic energy to various
acupuncture points, purportedly reliving headaches, migraines, muscular
aches and pains, circulation disorders, and skin disease. Another
variation on this theme-electroacupuncture biofeedback-is
promoted as a diagnostic tool capable of revealing the presence
of toxins, food allergies and 'imbalances.' Moving beyond acupuncture,
the electro-acuscope promises to relieve pain by running
current through damaged tissues. It is generally applied to such
conditions as muscle spasms, migraines, jaw pain, bursitis, arthritis,
surgical incisions, sprains and strains, neuralgia, shingles, bruises.
Microcurrent electrical therapy (MET) is also promoted for
pain relief in the muscles and joints, and is said to speed wound
healing as well. A device called the Light Beam Generator is advocated
for healing throughout the body. Other unproven devices attempt
to use sound and radio waves therapeutically. Cymatic instruments,
supposedly tuned to the 'frequency' of various tissues, are said
to diagnose aberrations and restore the tissues to health. Likewise,
the Sound Probe is employed to kill viruses, bacteria, and
fungi. A device called the Diapulse employs radio waves to
reduce swelling and inflammation following surgery. In almost all
cases, there is little, if any, published research in reputable
journals to back up the claims made for these instruments. It is
conceivable that some of them may actually be effective, but the
odds are not strongly in their favour.
Procedure
of Treatment
Transcutaneous
Electrical Nerve Stimulation: These treatments are administered
with a small electronic unit that sends pulsed currents to a set
of electrodes stuck to the skin. The electrodes are usually placed
near the painful area (often on either side), over a main nerve
leading to the painful area, on the spine one or two segments above
the spinal nerve receiving the pain, or at acupuncture points. Treatments
are typically given three to four times per day for 30 to 40 minutes
a session, or intermittently at the physician's and user's discretion.
Electroacupuncture:
Typically, the therapist inserts 4 to 20 thin disposable needles
into the patient's skin, either directly into the area of pain or
into traditional acupuncture points. Once the needles are in place,
they are stimulated with a low-level electrical charge. The treatment
generally takes 15 to 30 minutes.
Auricular
Acupuncture: Practitioners of this form of therapy believe that
each area of the ear is linked to a corresponding part of the body.
The therapist may apply gentle pressure to the part of the ear associated
with the problem, either by hand or with small acupuncture needles
and a weak electrical current or laser or infrared light. Electrical
therapy entails a very brief, 10-second burst of current at about
100 microamperes or less.
Microcurrent
Electrical Therapy: For these treatments, electrodes are placed
over the painful area on opposite sides of the body so that the
current will run through it. Treatment time varies with the size
of the injured or diseased site. The effect of the treatments is
said to be cumulative, so at least three treatments are typically
needed before pain relief sets in.
Benefits
of This Therapy
Transcutaneous
Electrical Nerve Stimulation: The pulsed currents delivered
in TENS are believed to 'drown out' pain signals in the affected
nerves, thus preventing the pain message from reaching the brain.
The method is based on the 'gate theory' of pain, which hypothesizes
that pain impulses must pass through a 'gate' in the spinal cord.
TENS units are also believed to stimulate the production of endorphins,
the body's natural painkillers. Although TENS has been intensively
tested, its degree of efficacy is still a subject to debate. While
a large 1990 study reported in The New England Journal of Medicine
pronounced TENS ineffective, several other trials have deemed it
capable of relieving pain, although it may be more helpful for m
ild to moderate discomfort than for severe pain. The type of tissue
may also be a factor; one study suggests that TENS works on skin
and connective tissue but not on muscle or the outer layers of the
bones.
Electroacupunctue:
Also called electro-acutherapy, this form of treatment operates
on essentially the same principles as regular acupuncture, with
the addition of a weak electrical current applied to the needles.
As in other forms of acupuncture, the goal is to correct purported
blockages in the flow of the life force qi, thus restoring
balance and health. Advocates of electroacupuncture say that it
is better suited to surgical anesthesia than manual therapy since
it reaches a large number of acupoints simultaneously. However,
use of any sort of acupuncture as the sole painkiller during surgery
is a feat that is rarely attempted.
Auricular
Acupuncture: The scientific basis of regular acupuncture has
never been explained, and acupuncture limited solely to the ear
is doubly mysterious. A few studies in the early 1980s-including
one Italian trial with 74 patients-claimed support for auricular
therapy. However, the technique was discredited by the American
Medical Association in 1984 when a study of 36 pain patients failed
to show a significant difference between those receiving the therapy
and those receiving a fake.
Electroacupuncture
Biofeedback: Employing a device called the Dermatron, advocates
of this procedure attempt to diagnose illness by measuring electrical
resistance at various acupuncture points that correspond to specific
organs and tissues An abnormal reading at any particular point is
the signal to check the other points associated with the organ in
question. Such devices have thus far been approved only on an experimental
basis in the U.S.
Cymatic Instruments:
According to proponents, each organ and tissue in the body emits
sounds at a particular harmonic frequency which can be recognized
by the cymatic device. Furthermore, it is said that any disturbances
can be remedied by bathing the site of the problem with sounds tuned
to the frequency pattern found in the organ's healthy state. The
existence of such frequencies has not, however, been accepted by
mainstream science.
The Diapulse:
This device emits radio waves that are said to produce short, intense
electromagnetic pulses capable of penetrating tissue to improve
blood flow, reduce pain and improve healing. Mainstream critics
charge that its value has yet to be verified in independent scientific
tests.
Electro-Acuscope:
This device is said to reduce pain, not by stimulating the affected
nerves as in TENS, but by promoting tissue repair. As the treatments
progress, the current is adjusted to alter the resistance from the
damaged tissue and thus accelerate recovery. Again, the treatments
await validation by independent scientific tests.
Light Beam
Generator: According to its proponents, this instruments works
by radiating light photons that assist in restoring the cells' normal
energy state, thus promoting healing. Mainstream critics are dubious.
Microcurrent
Electrical Therapy: Proponents of this therapy believe that
electrical stimulation of a wound or injured muscle promotes healing.
MET is one of the more intensively researched energy therapies.
To date, however, there is no consensus regarding its effectiveness.
MORA:
This instrument is supposed to receive electromagnetic signals directly
from the body, detect any aberrant wave patterns and replace them
with 'normal' waves delivered back to the patient via the acupoints
that correspond to the diseases area. As in traditional Chinese
acupuncture, this is thought to correct imbalances in the flow of
the life force, and thus the disorder. To grant this machine credibility,
you must assume the manufacturers know which waves are 'normal'
and which are not, that sending 'normalized' waves into the body
will correct them, and that these electromagnetic manoeuvres can
affect the undetectable life force posited by Chinese medicine.
There is no accepted scientific evidence for any of these contentions.
Sound Probe:
According to its advocates, this device emits a pulsed tone of three
alternating frequencies that can destroy any foreign matter, such
as viruses and bacteria, that is not in resonance with the body.
Who
Should Avoid This Therapy?
In
general, people with pacemakers and those who are pregnant should
avoid all forms of electrotherapy unless their doctor approves.
In addition, transcutaneous electrical nerve stimulation cannot
be used during electrocardiography or heart monitoring, and while
the patient is running a fever. The electrodes should not be applied
near the heart, head, and front of the neck or eyes. Although a
few studies have examined use of TENS for labour pains, the electrodes
should not be placed on the abdomen because their safety in pregnancy
has not been proven. All forms of electroacupuncture should be strictly
avoided during pregnancy, since there is a danger of triggering
premature uterine contractions. Techniques employing needles cannot
be used on people with bleeding disorders. It is also best to avoid
this form of therapy if you have a fever or any sort of irregular
heartbeat.
Side-effects
Transcutaneous
electrical nerve stimulation, the most thoroughly studies of these
therapies, appears to have no side effects. The stimulation with
the other forms of treatment is really unknown. Remember, however,
that with most of them you are playing with electricity.
