In this session, you will learn about PEMF (Pulsed Electromagnetic Field) stimulation and how it can enhance acupuncture. PEMF has been extensively studied since World War II. Veterinarians working with racehorses were early adopters of this modality. The FDA approved the first non-invasive PEMF devices for human use in the 1970s. Interest increased when NASA research showed that PEMF therapy could alleviate the most common health problems experienced by astronauts, which also happen to be the most frequent complaints among terrestrial patients who come to PEMF therapy, including pain in muscles and joints, fatigue, insomnia, inflammation, impaired blood flow, and kidney stones among others. This presentation will provide an overview of mechanisms, theory, function, and benefits of PEMF. An overview of PEMF devices will also be provided.
