PEMF for Osteoporosis
What is osteoporosis?
Osteoporosis affects an estimated 75 million people in the USA, Europe and Japan. Fractures related to osteoporosis are expected to double during the next 5 decades, and it is also expected that the occurrence of osteoporosis in men will increase.
The currently accepted definition of osteoporosis is “systemic skeletal disease characterized by low bone mass and micro architectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture risk”.
Bone mass is the amount of bone tissue contained in the skeleton. It may be expressed in terms of bone mineral content (total grams of bone mineral within a given area of bone) or in terms of bone mineral density (bone mineral content normalized for the projected area).
The measuring of bone mineral is reasonably accurate and therefore these tests form the basis for diagnosing osteoporosis and predicting bone fracture risk.
Bone density begins to decrease after the age of 40. If it decreases enough to reach the “fracture threshold”, the person is at significant risk of a fracture. This threshold is individual and may occur at different ages and is also dependant on generic and environmental factors, including one's diet and activity level.
Osteoporosis and back pain
Osteoporosis patients often suffer from persistent back pain. This pain is caused by very painful micro-fractures in the vertebrae of the spine. Using the Parmeds system for a few weeks relieves the pain as it closes these micro-fractures.
A longer series of treatments improves bone density.
A study at the Pacific Health Research Institute in Honolulu was designed to provide concrete data on the restoration of bone mass in post-menopausal females. Bone density rose with an average of 5.6%. At the University of Graz in Austria a similar study clearly showed an increase in bone density after one year of around 6%. These results make all the difference in functioning in good health or suffering with an increasing risk for spontaneous fractures. The proportionate increase in fracture risk is directly related to decreased bone density.
Electro-Magnetic Field Therapy for Osteoporosis
Selected low-energy time-varying electromagnetic fields have been used to treat un-united fractures (non-unions) during the past 15 years. More than 100,000 patients have been treated, and retrospective studies have substantiated their biological effectiveness in large numbers.
Bone is responsive to the mechanical demands placed on it. When loading diminishes, as it does during bed rest, immobilization and weightlessness, bone mass is lost. On the other hand when loading is increased correctly, bone mass increases.
Results of bio-mechanical and histological investigations prove that electromagnetic fields not only prevent bone loss, but also restore bone mass, once lost.
A program was set up at McGill University of Montreal, where it was found that electromagnetic fields damp bone resorption activity. In addition it was found that selected electro-magnetic fields increase bone formation.
The resorption of bone is lowest and the formation of new bone the greatest when energy of the imposed fields is concentrated in the lower frequency components.
These results are consistent with other studies showing that cells respond to a broad spectrum of frequencies. They appear to be most sensitive to frequencies in the range of those produced endogenously, that is in the range of 1000 Hz or less. Tissue dosimetry studies show that the frequency response of cortical bone over a range of 100 Hz to 20 kHz shows a steep roll off between 100 and 200 Hz.
Electro-magnetic fields at specific frequencies have been shown to produce osteogenic effects in a turkey ulna model. Furthermore low-amplitude signals decrease bone resorption in a canine fibular model.
Lifestyle factors like malnutrition, smoking, excessive use of alcohol and a sedentary lifestyle contribute to, and worsen, osteoporosis. It is not known whether this response derives from decreased osteoblastic activity, increased osteoclastic resorption, or both.
Fractures in elderly people can heal in normal intervals, showing that osteoblasts can be activated by appropriate stimuli.
A study led by Associate Prof. Dr. W. Passath and Prof. Dr. G. Leb of the Medical Clinic of the Karl Franzen University of Graz in Austria was designed to provide concrete data on the restoration of bone mass in post-menopausal females. A total of 36 female patients between the ages of 46 and 61, all with decreased bone mineral density as defined by a bone densitometer, were treated during a period of 8 to 12 weeks. One year after the study the average bone density had increased by 5.81 percent.
In another study “Prevention of osteoporosis by pulsed electromagnetic fields” by Clinton T. et.al. of the Department of orthopedics, State university of New York, Stony Brook, increased bone mass of 12.3 and 9.7 percent are mentioned.
Electromagnetic fields do modify biological behavior by inducing electrical changes around and within the cell. The key to rational use of electro-magnetic fields lies in the ability to define the specific treatment parameters (amplitude, frequency, wave form, orientation and timing). Various studies have clearly shown that bone density does increase in osteoporosis-prone patients exposed to specific pulsed electromagnetic fields. Properly applied pulsed electromagnetic fields, if scaled for whole body use, have clear clinical benefits for treatment of osteoporosis.
Bone density values in individuals are expressed in relation to a reference in Standard Deviation (SD) units. This reduces the problems associated with differences between the various measuring instruments; however it does require defined “normal” ranges.
In young healthy women, low bone mass (osteopenia) is present when the bone mineral density (BMD) is below 1 SD but not below 2.5 SD of the mean value of peak bone mass. If this value is more than 2.5 SD below this value, the patient is suffering from osteoporosis.
Until a fracture occurs, osteoporosis is asymptomatic. Fracture risk is related to bone mass, and when bone mass decreases, the risk of fracture increases.
The risk of fractures can change significantly even due to relatively small changes in bone mass.
Osteoporotic fractures are associated with significant morbidity and mortality. The most important complaint of patients with osteoporosis is acute or sporadic back pain following normal activity. The pain usually lasts a few days or weeks and then subsides. Such episodes recur and may result in chronic backache. The episodes are due to crush fractures of vertebrae. As the disease progresses, loss of height, spinal deformity and fractures occur.
Hip fractures, in particular, frequently have grim prognosis. The mortality rate of osteoporotic hip fractures is between 15% and 20%, primarily due to pulmonary emboli, pneumonia, and other complications of surgery and prolonged hospitalization. The lifetime risk of hip fractures in white women is as great as the risk of breast, endometrial and ovarian cancer combined. One half of patients who survive a hip fracture are unable to walk unassisted and 25% are confined to nursing homes. In up to 20% of hip fractures the patient dies within 6 months
Parmeds PEMF therapy Improves Bone Density
Case Study: Parmeds PEMF system improves bone density!
In January 2008, J.N., a trim, active 87 year old female, came in to the Viera Diagnostic Center and was diagnosed with a modern Lunar bone densitometer.
According to the classification of the World Health Organization, a T-score lower than -2.5 shows that a person suffers from osteoporosis.
The measured Bone Mass Density of J.N in her Spine was 0.785 g/sq.cm corresponding with a T-score of -3.3, affirming that she was suffering from severe osteoporosis.
Around June 2008 she purchased a Parmeds 2000XP device with a full body mattress and used the device on a daily basis.
In December 2009 [18 months after starting treatment with the Parmeds] she was diagnosed again at the same center; however this time she showed a huge improvement in the measured values with a Bone Mass Density of 0.854 g/sq.cm corresponding with a T-score of -2.7, reflecting an improvement of 8.8% vs. her previous measured values! And all this within only 18 months!
Here is a scan of the report of Viera Diagnostic Center:
Here follows the testimonial & full documentation proof of more than 10% increase in bone density after only one year of Parmeds PEMF use!
I purchased the Parmeds XP after being diagnosed with osteoporosis. The last thing I wanted to do was drug therapy. I gave myself one year using the Parmeds mattress and high energy coil before returning to my specialist for a follow up bone scan.
The results were quite amazing a 10.4% increase in bone density in the area between L1 to L4. I have forwarded my old and new scans on to Ben at Parmedsic and given him permission to share these results with anyone who would like to view them. My wife loves it for all sorts of ailments and my 15 year son is on it often for sporting injuries. It is the absolute best thing I have ever done for my overall health.

Bone Density. How are the measurements done?
Single- and Dual Photon Absorptiometry
Single photon absorptiometry (SPA) was already developed half a century ago. This technology makes use of a focused beam of radionuclide radiation which passes across the arm. Denser tissue like bone blocks radiation better than soft tissue and bone density can be calculated out of these differences.
The disadvantage of this technology is that it requires uniform soft tissue surrounding the bone to be measured. It is also not possible to use this technology for measurements of bone density of the hip and spine and these are important places where fratures happen more often.
Single photon absorptiometry has provided important information based on epidemiological studies, especially on the effects of skeleton aging.
More sophisticated technique based on the same principle as used for SPA is dual photon absorptiometry (DPA).
Development of this technology was done in the 1970's and the first systems came on the market in the 1980's.
DPA makes use of radioactive isotopes by emitting radiation at two different intensity levels, instead of the single intensity level used for SPA measurement.
During whole body scans both different energy levels are detected and form the basis to perform calculations to obtain different values for the different amounts of energy transmissions through the body. This technology is more accurate and precise for obtaining the bone density values.
Single Energy X-ray Absorptiometry
An X-ray tube is used for SPA instead of a radio nuclide photon source. Disadvantage of this technology is that this technology cannot be used for spine and hip measurements.
Dual Energy X-ray Absorptiometry
Dual Energy X-ray Absorptiometry (DXA or DEXA) was introduced during the 1980's. Nowadays DXA devices are used world-wide and this technology is standard to obtain reliable bone density data.
The technology of DXA is in principle similar to DPA except for the radionuclide source. The source is now replaced with an X-ray system. DXA has many advantages compared to the older absorptiometry methods. Measurements are faster and expose the patient to less radiation. Of course the most important is that the results of the measurements are more precise. With the development of p-DXA technology it is also possible to measure the density of the forearm, which represents reasonably accurate both mid-distal and ultra-distal information during the same scan.
Bone density can also be determined by reference to a metal calibration wedge on X-ray film. Such a wedge is placed alongside the hand during an X-ray procedure. Radiographic densitometry is an old technology and not used anymore in the modern western world.
Quantitative Computed Tomography
Quantitative Computed Tomography (QCT) is done with the help of a modification on regular CT X-ray scanners.
Images generated by CT systems are used to compute a large quantity of X-ray transmission values measured in different directions. The X-ray system rotates around the body in a fixed plane. Calculations made from CT scans and bone density values are obtained by referencing to density of pre-calibrated phantoms.
Higher radiation exposure than with other bone density measuring technologies is a disadantage however. This form of measurement is sometimes used for older people where age-related osteoarthritis and aortic calcification do interfe with absorptiometric measurement technology.
A wide range of quantative ultrasound have flooded the market during the last few decades for the assessment of skeletal status.
Quantitative Ultrasound (QUS) measurements are done on patella, heel bone, tibia, and ulna.
Broadband Ultrasound Attenuation (BUA) and Velocity or Speed of Sound (SOS) are calculated. These devices give quantitative data averaged over the measurement area and Quantitative Ultrasound Index (QUI). Various calcaneal systems also generate a picture.
Ultrasound systems do have an advantage to obtain information without any ionizing radiation. On the other hand the quantity of radiation generated by modern DXA systems is very low. The main reason for buying an ultrasound system is the much lower price and portability for these devices than for DXA devices.
There are not yet many long term studies of QUS changes. Measurement results as percentage levels may be misleading because of the different devices and calibrations used. Studies show that precision errors for QUS measurement results are several times higher than corresponding DXA results.
Because this technology does not give absolute BMI data QUS should only be used only for fracture risk prediction.
Chemical measurements of blood and urine samples with the help of biochemical screening assays for bone markers are in use to determine bone resorption and bone formation.
Biochemical screening assays still have a large accuracy error and are thus not in much use.
These screenings are mainly used for bone turnover studies in large groups of people to compensate for individual statistic errors.
Laboratory tests for urinary hydroxyproline and pyridinoline crosslinks or serum alkaline phosphatase cannot be used to diagnose osteoporosis. In general they are not in use for evaluation of an imbalance between formation and destruction of bone. They might be useful to determine bone turnover and in identify people at risk for fast bone loss.
