The authors present their experience with the healing influence of
permanent magnets on postoperative wounds. The responses of 20 patients
who underwent suction lipectomy and postoperative negative magnetic
field therapy were studied in a double-blind fashion. Magnets in the
form of patches (10 patients) or sham magnet patches (10 patients) were
placed over the operative region in each of the patients. Pain, edema,
and discoloration (ecchymosis) were evaluated at 1, 2, 3, 4, 7, and 14
days postoperatively. Our results show that the treatment group had
significant reductions in pain on postoperative days 1 through 7, in
edema on days 1 through 4, and in discoloration on days 1 through 3 when
compared with the control group. These results demonstrated that
commercially available magnets have a positive influence on the
postoperative healing process in suction lipectomy patients.

Use of permanent magnetic field in reconstructive surgery of the main arteries (experimental study).
Lud GV, Demeckiy AM.
Department of Surgery, Vitebsk Medical Institute, USSR.
To achieve better results in reconstructive surgery on the main
arteries using venous graft, the authors used a permanent magnetic field
from different sources: elastic magnets with external effect and
absorbable magnets implanted into the surgical wound. This physical
source was found to possess the following effects: stimulation of the
central and peripheral blood flow, hypercoagulation prevention,
reduction on edema and inflammation. The restored specific properties of
these magnetic sources should be taken into account in the selection
and use during the postoperative period.

Morphological evaluation of MRC-5 fibroblasts after stimulation with static magnetic field and pulsating electromagnetic field.

The quality of tissue repair and the speed with which that repair can
be accomplished are the two major variables in the healing of any
injury. Today, magnetic field exposure to traumatized areas has shown to
be a promising tool in the healing process. The exact mode of action by
which radiating and unchanging magnetic fields still has to be
elucidated. The objective of this study was to evaluate the morphology
of MRC-5 fibro-blasts after stimulation with static and pulsating
magnetic fields. Under sterile environment, a total of 24 wells were
loaded with 50,000 MRC-5 cells each and further divided into three
groups. Groups 1 and 2 were exposed to magnetic fields, static and
pulsating respectively. Group 3 wells were unexposed and served as the
control group. The cells were monitored at 0, 24, 48, and 72 hours and
representative views were captured using digital analysis techniques.
The live cells were screened for cellular mobility, cell distribution,
and cellular morphology (size, shape, lysis, and background). After 72
hours, the supernatants and cells of all three groups were collected and
MDA analysis was performed to determine possible cellular damage. Group
1 cells continued to grow at a reasonable rate, but there was
substantial cell membrane damage (high MDA levels, p < 0.05). Group 2
cells appeared to be very stressed under these conditions especially at
the initial phase (24 hours). In conclusion, the use of pulsating
magnetic stimulation can be beneficial in the healing process of soft
tissues.

Electromagnetic fields and magnets. Investigational treatment for musculoskeletal disorders.
Trock DH.
Yale University School of Medicine, New Haven, Connecticut, USA.
Certain pulsed electromagnetic fields (PEMF) affect the growth of
bone and cartilage in vitro, with potential application as an arthritis
treatment. PEMF stimulation is already a proven remedy for delayed
fractures, with potential clinical application for osteoarthritis,
osteonecrosis of bone, osteoporosis, and wound healing. Static magnets
may provide temporary pain relief under certain circumstances. In both
cases, the available data is limited. The mechanisms underlying the use
of PEMF and magnets are discussed.

Clinical effectiveness of magnetic field therapy - a review of the literature.

To verify the efficacy of electromagnetic fields on various diseases
we conducted a computer-assisted search of the pertinent literature. The
search was performed with the aid of the Medline and Embase database
(1966-1998) and reference lists. Clinical trials with at least one
control group were selected. The selection criteria were met by 31
clinical studies. 20 trials were designed double-blind, randomised and
placebo-controlled. The studies were categorised by indications.
Electromagnetic fields were applied to promote bone-healing, to treat
osteoarthritis and inflammatory diseases of the musculoskeletal system,
to alleviate pain, to enhance healing of ulcers and to reduce
spasticity. The action on bone healing and pain alleviation of
electromagnetic fields was confirmed in most of the trials. In the
treatment of other disorders the results are contradictory. Application
times varied between 15 minutes and 24 hours per day for three weeks up
to eighteen months. There seems to be a relationship between longer
daily application time and positive effects particular in bone-healing.
Patients were treated with electromagnetic fields of 2 to 100 G (0.2 mT
to 10 mT) with a frequency between 12 and 100 Hz. Optimal dosimetry for
therapy with electromagnetic fields is yet not established.

Evolution of magnetic therapy from alternative to traditional medicine.
Vallbona C, Richards T.
Department of Family and Community Medicine, Baylor College of Medicine, Houston, Texas, USA.
Static or electromagnetic fields have been used for centuries to
control pain and other biologic problems, but scientific evidence of
their effect had not been gathered until recently. This article explores
the value of magnetic therapy in rehabilitation medicine in terms of
static magnetic fields and time varying magnetic fields
(electromagnetic). A historical review is given and the discussion
covers the areas of scientific criteria, modalities of magnetic therapy,
mechanisms of the biologic effects of magnetic fields, and perspectives
on the future of magnetic therapy.

Pulsed magnetotherapy in Czechoslovakia - a review.
Jerabek J.
National Institute of Public Health, Praha, Czech Republic.
Pulsed magnetotherapy has been used in Czechoslovakia for more than
one decade. It has been proved that this type of physical therapy is
very efficient mainly in rheumatic diseases, in paediatrics (sinusitis,
enuresis), and in balneological care of patients suffering from
ischaemic disorders of lower extremities. Promising results have also
been obtained in neurological diseases (multiple sclerosis, spastic
conditions) and in ophthalmology, in degenerative diseases of the
retina.

Beneficial effects of electromagnetic fields.
Bassett CA.
Bioelectric Research Center, Columbia University, Riverdale, New York 10463.
Selective control of cell function by applying specifically
configured, weak, time-varying magnetic fields has added a new, exciting
dimension to biology and medicine. Field parameters for therapeutic,
pulsed electromagnetic field (PEMFs) were designed to induce voltages
similar to those produced, normally, during dynamic mechanical
deformation of connective tissues. As a result, a wide variety of
challenging musculoskeletal disorders have been treated successfully
over the past two decades. More than a quarter million patients with
chronically ununited fractures have benefitted, worldwide, from this
surgically non-invasive method, without risk, discomfort, or the high
costs of operative repair. Many of the athermal bioresponses, at the
cellular and subcellular levels, have been identified and found
appropriate to correct or modify the pathologic processes for which
PEMFs have been used. Not only is efficacy supported by these basic
studies but by a number of double-blind trials. As understanding of
mechanisms expands, specific requirements for field energetics are being
defined and the range of treatable ills broadened. These include nerve
regeneration, wound healing, graft behavior, diabetes, and myocardial
and cerebral ischemia (heart attack and stroke), among other conditions.
Preliminary data even suggest possible benefits in controlling
malignancy.
