Pulsed electromagnetic field therapy (PEMF) is a technique that treats diseases by applying electromagnetic field pulses to the human body to produce biological effects. The following is information about its treatment methods:
Therapeutic Principle
When applied to the human body, PEMF induces the vibration of ions and charged particles within tissues, thereby increasing cell membrane permeability, promoting cell metabolism, and reducing inflammation, thereby achieving the therapeutic effect.
Applications
Orthopedic Conditions: Low-frequency pulsed electromagnetic fields (PEMF) can accelerate fracture healing, especially for patients with nonunion or osteoporosis, by stimulating osteoblast activity and promoting calcium deposition.
Chronic Pain: For conditions such as osteoarthritis, cervical spondylosis, low back pain, and sciatica, PEMF can inhibit the release of inflammatory factors, relieve pain, and improve local microcirculation.
Sports Injuries: High-frequency electromagnetic waves are often used to repair soft tissue injuries, reducing muscle swelling and shortening recovery time.

Other Conditions: PEMF has also been used to improve sleep, control blood sugar, enhance immune function, and reduce weight. In a 2001 double-blind trial of PEMF therapy for insomnia, 70% of patients reported a complete resolution of their insomnia symptoms, 24% reported significant improvement, and 6% reported a small but significant improvement.

Safety
PEMF therapy is generally safe, but some new users, especially those using systemic therapy, may experience some unpleasant side effects, such as increased pain, mild weakness, dizziness, and brain fog. These effects are often caused by the temporary increase in blood circulation that puts a strain on the body. They typically occur only within the first week of treatment and are more common with systemic therapy than with topical therapy.
