PEMF stands for Pulsed Electromagnetic Field (or Fields), which is a non-invasive physical therapy that uses lowfrequency
electromagnetic pulses to stimulate the body's cells and promote healing.
How It Works:
The human body naturally uses electromagnetic signals for cellular communication and function. When the body's cells are
damaged due to injury, stress, or illness, their natural electrical charge can be disrupted, which slows down the healing
process.
PEMF therapy works by:
Inducing microcurrents: The applied time-varying magnetic field induces small electrical currents within the target tissues,
mimicking natural bioelectric processes in the body.
Restoring cellular function: These currents help to "recharge" the cells, restoring their optimal electrical potential. This, in
turn, improves the movement of ions (like calcium, sodium, and potassium) across cell membranes, which are crucial for
cellular functions.
Enhancing cellular processes: The restored cellular function leads to increased oxygenation and blood microcirculation in
the affected area, production of essential proteins and growth factors (like collagen), and faster removal of waste products.
Reducing in flammation:
PEMF has an anti-in flammatory effect by modulating in flammatory pathways and balancing proand
anti-in flammatory cytokines.
Clinical Applications:
PEMF therapy is considered safe and is used as a standalone or adjunctive treatment for various conditions, primarily related
to the musculoskeletal system. In the United States, speci fic PEMF devices have received FDA approval for certain uses:
Healing non-union bone fractures (approved in 1979)
Adjunct treatment to spinal fusion surgery
Treatment of post-operative pain and edema
It is also widely used for other conditions such as:
Osteoarthritis and osteoporosis
Chronic pain and in flammation
Tendon and ligament repair
Wound healing and soft tissue regeneration
Important Considerations:
PEMF therapy is non-invasive and generally associated with few side effects. However, it is generally contraindicated for
individuals with pacemakers or other implanted electronic devices, pregnant women, and people with a history of epileptic
seizures.
