Magnetterapi Following are descriptions of recent studies, published in
peer-reviewed scientific journals, on the impact of treatment with
magnetic fields on a variety of conditions. Alzheimer's Disease This article reports on two Alzheimer's patients who
experienced significant improvement in visual memory and drawing
performance following the external application of electromagnetic fields
ranging from 5 to 8 Hz. Improvements were also seen in other cognitive
functions, including spatial orientation, mood, short-term memory, and
social interactions.1 This article reports on three patients with amyotrophic
lateral sclerosis who experienced beneficial effects following treatment
consisting of three sessions per week of pulsed magnetic fields
administered via a Magnobiopulse apparatus. Patients received upwards of
75 total sessions prior to achieving maximum recovery.2 This study examined the effects of low-frequency and constant
magnetic fields in patients suffering from rheumatoid arthritis and
osteoarthrosis. Low-frequency magnetic fields were shown to produce
beneficial effects in patients with both stage I and II rheumatoid
arthritis and with osteoarthrosis deformans, especially with respect to
the wrists, knees, and ankles.3 This study examined the effects of bone grafting and pulsed
electromagnetic fields on a group of 83 adults with ununited fractures.
Results showed a successful healing rate of 87 percent in the 38 patients
originally treated with bone grafts and PEMF for ununited fractures with
wide gaps, synovial pseudarthrosis, and malalignment. A healing rate of 93
percent was shown among the 45 patients who had initially been
unsuccessfully treated with PEMF alone and had bone-grafting and were
re-treated with pulsing electromagnetic fields.4 Results of this study found that 20-30 sessions of
magnetotherapy administered preoperatively exhibited antitumor effects in
patients suffering from lung cancer.5 Results of this study found that the addition of
magnetotherapy to the treatment of patients suffering from ischemic heart
disease and osteochondrosis led to clinical improvements.7 In this study, 320 diabetics received impulsed magnetic field
treatment while 100 diabetics (controls) received conservative therapy
alone. Results showed beneficial effects with respect to vascular
complications in 74 percent of the patients receiv-ing magnetotherapy
combined with conservative methods, compared to a 28-percent effectiveness
rate among controls.8 This article reports on the cases of three patients with
partial seizures who received treatment with external artificial magnetic
fields of low intensity. Such treatment led to a significant attenuation
of seizure frequency over a 10-14-month period.10 In this study, patients with primary open-angle glaucoma with
compensated intraocular pressure were administered magnetotherapy using an
ATOS device with 33-mT magnetic field induction. The procedure was
administered to a patient in a sitting posture with a magnetic inductor
held before the eye. Sessions lasted 10 minutes and each course included
10 sessions. Following 4-5 months of therapy, results showed improved
vision acuity 0.16 diopters, on an average of 29 out of 30 eyes with
vision acuity below 1.0.11 This
double-blind, placebo-controlled study examined the
effects of pulsed electromagnetic fields on hair loss in men suffering
from male pattern baldness. PEMF exposures were administered to the head
for 12 minutes and were given weekly or twice weekly over a period of 36
weeks. Results found the PEMF treatment both prevented hair loss and
promoted regrowth without side effects.12 Results of this double-blind, placebo-controlled study
demonstrated that the administration of a pulsed magnetic field for less
than one hour to headache patients produced significant beneficial effects,
as shown subjective patient reports, as well as EEG activity.13 This review article examined the data concerning impulsed
magnetic fields in the treatment of lupus erythematosus. Studies indicate
that the treatment can be beneficial due to its anti-inflammatory and
analgesic effects, its positive action on microcirculation, and
immunological reactivity.15 This article reports on the case of a 55-year-old female
chronic progressive multiple sclerosis patient who received a single
external application of low magnetic fields (7.5-picotesla; 5-Hz frequency)
which lasted 20 minutes. The treatment quickly led to improvements in a
variety of areas, including fatigue, sleep, vision, bladder function,
movement and speech problems, and mood.16 This study examined the effects of pulsed electromagnetic
fields (Gyuling-Bordacs device) in patients suffering from peripheral
muscle paralysis. Treatment consisted of 20-minute exposures (2-50 Hz, 70
G). Results showed 50-Hz pulsed electromagnetic fields to be the most
effective level of treatment and that such therapy enhanced muscle
irritability in peripheral paralysis patients as well as in healthy
controls.17 This
double-blind, placebo-controlled study examined the
effects of low-energy pulsed electromagnetic fields administered via soft
collars on patients suffering from persistent neck pain. Results indicated
significantly beneficial effects following three weeks of treatment.18 This controlled study found that exposure to pulsed
electromagnetic fields enhanced the speed and degree of peripheral nerve
regeneration twofold in rats with experimentally severed sciatic nerves.19 Results of this double-blind, placebo-controlled study
indicated that exposure to pulsed electromagnetic fields had beneficial
effects in the treatment of patients suffering from painful osteoarthritis
of the knee or cervical spine. PEMF therapy consisted of 18 exposures
lasting 30 minutes and administered 3-5 times per week.
20 This study examined the effects of a 72-Hz pulsating
electromagnetic field administered for 10 hours per day over a period of
12 weeks on bone density in women prone to osteoporosis. Results found
significant increases in bone mineral density in the area of EMF exposure.21 Externa This study examined the effects synchronizing pulse
waves in the impaired area when treating patients suffering from acute
diffuse otitis externa with low-level magnetic fields in combination with
conventional therapies. Patients were divided into 3 groups. The first
received ultrahigh-frequency or very-high-frequency electromagnetic waves.
The second received 15-minute daily exposures to 50-Hz alternating or
pulsating 20-mT magnetic fields. The third group was treated switching on
the same magnetic fields only during propagation of the pulse wave through
the ear vessels. Results showed a 100 % recovery rate in patients across
all 3 groups, with recovery taking the least amount of time among those in
group 3.22 This controlled study examined the effects of combining
pulsed electric stimulation and laser light with conventional treatment in
patients suffering from acute pancreatitis. Results showed the combined
therapy to have the most significant effects in patients with severe forms
of the disease. 23 This article reports on the case of a medicated 61-year-old
Parkinson's patient who experienced rapid reversal of symptoms following a
single external application of picotesla-range magnetic fields.24 Results of this study showed that magnetic laser therapy
decreased the severity of acute respiratory insufficiency and treatment
course, and prevented destructive complications in children with
infiltrative acute destructive pneumonia between the ages of 1 and 12
years. 25 Noting the well-established dangers associated with
electroconvulsive therapy, the author, in this theoretical article, argues
that transcranial magnetic stimulation should be looked at as an
alternative psychiatric treatment. The author asserts that TMS has several
advantages over ECT in that it is painless, noninvasive, and more
effective on deep structures of the brain.26 Results of this study showed that the use of low-frequency
magnetic fields helped to prevent and treat critically ill patients
suffering from pyoinflammatory bronchopulmonary complications, and to
prevent such complications as well.27 Results of this double-blind, placebo-controlled study
indicated that low-energy-emission therapy significantly improved sleeping
patterns among patients suffering from chronic psychophysiological
insomnia. Therapy was administered 3 times per week, always in late
afternoon and for 20 minutes, over a period of 4 weeks.28 Results of this study found that exposure to constant magnetic fields improved healing in rats with experimentally induced spinal cord injury, and in human patients suffering from spinal cord trauma as well. 29 Results of this study demonstrated that treatment with
sinusoidal modulated currents coupled with transcerebral magnetic fields
proved more effective than either therapy on its own in the treatment of
stroke patients during the period of early rehabilitation.30 This article reports on the case of a 6-year-old boy
suffering from Tourette's syndrome who experienced improvements in
visuoconstructional and visuomotor skills, along with more general
symptomatic improvements, following the extracranial application of
electromagnetic fields in the picotesla range of intensity. 31 This study compared the effects of traditional drug treatment
(TDT) to those of microwave resonance therapy (MRT) in patients suffering
from duodenal ulcers. Results indicated the mean hospital stay for
patients in the TDT group was approximately 22 days. Throughout this
period, ulcers healed in 38% of patients, were reduced in 17%, showed no
change in 43%, and increased in 2%. No pain relief was seen in 32%.
Contrast, mean discharge time for patients in the MRT group was
approximately 12 days. Pain was generally stopped in 3-6 days. Complete
healing occurred in 81%, a decrease was seen in 16%, and ulcer size did
not change in just 3%. Remission occurred in 98% of such patients.32 This review article discusses the theoretical and clinical
applications of magnetic field therapy in the treatment of trophic ulcers
of the lower limbs.33 In this article, the authors report on their successful use of magnetic-laser therapy in inflammations of the urinary system in a urological clinic setting.34 Se även www.bravara.se |
