Magnetic therapy is a treatment that uses the effects of the magnetic field on the body.
Two solenoids (electromagnet) are applied to the joint to be treated.
When the electromagnet is crossed by an electric current creates a magnetic field, so it transmits magnetic energy.
The human body contains many metallic substances inside, as everyone knows, in blood tests there is also the “iron”.
The magnetic field exerts a force on ferromagnetic, paramagnetic and diamagnetic molecules.
Within the body, there are a large number of ions, or molecules with a positive or negative electrical charge.
The properties of magnetic therapy devices are frequency and intensity.
In medicine machines are often used around 30 to 60 Hz because scientific research shows that working this way can achieve greater energy transfer at the joint level.
The magnetic field is not static, but must reverse the polarity to give positive effects on the pathology.
The intensity is the measure of the amount of electrical charges that travel through the solenoid or the electromagnet and is expressed in degrees.
The rented appliances do not exceed the peak power of 30 degrees while the ambulatory machines reach up to 100 degrees. We can distinguish three types of magnetic therapy:
- With static magnetic field
- With low frequency
- With high frequency.
The static magnet applied to the joint or bone can hardly interact with the anatomical region properly, as it only works in one direction.
Magnetic therapy with a static magnetic field can not be considered scientifically proven.
High or low frequency magnetic therapy only benefits if the duration of treatment is long enough.
Scientific studies show that magnetic therapy can reduce healing time by half, especially in the case of fracture and arthropathy.
It requires an application of at least one hour per day for a few weeks, the minimum treatment lasts for 20 days.

Why is a therapy that gives excellent results (as demonstrated by many scientific studies since the 1970s and 1980s) rarely prescribed by doctors?
Often the patient who has suffered a fracture leaves the emergency room without a prescription for magnetic therapy that can reduce recovery times and bone healing.
What is the difference between a portable and an outpatient magnetic therapy?
The intensity of the machine is measured in degrees.
A portable device has a power between 3 and 30 degrees, while the professional fixed appliance has a peak power of 100 degrees.
With a higher intensity the healing time is shorter and the sessions are shorter.
It is generally recommended to keep the portable machine at least 4-8 hours a day; for convenience, the patient can carry in the pocket during the day or sleep with her at night.
If the intensity is between 50 and 100 degrees a session of 30-60 minutes is sufficient for the musculoskeletal disorders in which it acts.
Magnetic therapy is inexpensive because manual intervention of the physiotherapist is not necessary.
How does the magnetic field work in the human body?
The effects on the body are:
- At the level of the cell membrane depolarization may occur due to : trauma , inflammation, etc. In this case, there is an accumulation of sodium inside the cell, which invokes the inflammatory fluid causing swelling or edema. Magnetic energy depolarizes the cell membrane that can restore adequate sodium content in the cell. Consequently, it improves the permeability of the cell membrane, the consequence is an increase and acceleration of the exchanges between the cell and the external environment.
- Increases cellular metabolism , releases energy contained in energy molecules ( ATP ) and consumes more oxygen.
- Anti-inflammatory and anti-emetic effect (promotes drainage of swollen joints).
The effect on the muscles is relaxation , so it tends to dissolve the contractures .
- At vascular level, magnetic therapy works by increasing peripheral blood flow and therefore the effect is better circulation.
- Piezoelectric action favors osteoblasts (cells that hold calcium in the bones) and inhibits osteoclasts, the cells that destroy the bone.
- An increase in the production of collagen fibers.
The magnetic flux penetrates the body up to 5/6 centimeters; in deep joints such as the hip and knee, it is necessary to apply at least two electromagnets.
What is the minimum duration of treatment?
The treatment should be customized according to the disorder.
If the patient has suffered a fracture or suffers from osteoporosis you should apply the machine for at least one hour a day.
In the case of arthrosis and joint inflammation, the duration of treatment may be less, but a session of less than 30 minutes is useless.
What are the effects?
The machine acts on cells helping to regenerate bone tissue, improving blood circulation and reducing swelling. Magnetic therapy has scientific evidence in the stimulation and assimilation of calcium in the bones, which is vital for those who have suffered fractures.
The indication of therapy is for recent fractures, delayed consolidation, osteoporosis, Sudeck’s disease, pseudarthrosis, inflammatory and degenerative arthropathy, back pain , metatarsalgia , heel spurs and is contraindicated in cases of people with macarpasso and during pregnancy .
What are the contraindications?
Magnetic therapy is contraindicated to:
- Persons with pacemakers or electronic equipment because there may be interference
- In the presence of neoplastic diseases because they accelerate development.
As a relative contraindication it may have vasodilatation effects and is not recommended in case of: hematological disorders, coronary disease or vascular epilepsy, some infectious diseases , mycosis, hyperthyroidism , endocrine syndromes, tuberculosis and pregnancy.
