Pulsed electromagnetic field therapy
Pulsed electromagnetic field therapy (PEMF), also known as low field magnetic stimulation (LFMS), and tumor treating fields (TTF) is a therapy method used in the field of orthopedics, physiotherapy, sports medicine, oncology, and neurology. This therapy involves the use of electromagnetic fields in an attempt to heal non-union fractures and depression.
History[edit | edit source]
The history of PEMF dates back to the early 20th century with Tesla's pioneering work in electromagnetism. However, it was only in the late 20th century that the therapy gained scientific interest and began to be used for medical purposes.
Mechanism of action[edit | edit source]
PEMF works by directing powerful, pulsed energy waves toward damaged or injured areas of the patient's body. These waves quickly pass through the cells in the damaged region, increasing the spin of the electrons contained within them as a result.

Applications[edit | edit source]
PEMF therapy is used in various medical fields. In orthopedics, it is used to treat non-union fractures, in physiotherapy and sports medicine, it is used to treat pain and inflammation. In oncology, it is used as a method of tumor treating fields (TTF), and in neurology, it is used to treat depression.
Effectiveness[edit | edit source]
The effectiveness of PEMF therapy has been widely studied. While some studies report positive effects of the therapy, others do not find any significant improvement. The effectiveness of the therapy may depend on a variety of factors including the condition being treated, the intensity and duration of treatment, and the specific device used.
Safety[edit | edit source]
PEMF therapy is generally considered safe, with few side effects reported. However, the therapy should not be used in people with certain medical conditions, such as epilepsy or pregnancy, without first consulting a healthcare provider.
