Frequency Specific Microcurrent (FSM)

Photo of attendees of the March 2014 FSM Core course held in PortlandFrequency Specific Microcurrent is an innovative modality using micro-amperage current to create beneficial changes to symptoms and health.  Microcurrent increases ATP production by 400-500%.  Due to the resonance effects of the frequencies on tissues and conditions, it can effect changes in inflammation, range of motion, nerve and muscle pain

The effectiveness of FSM depends almost entirely on an accurate diagnosis.  Pain in a joint can come from muscles, tendons, bursae, discs, nerves, etc.  If the pain is coming from the bursa and you treat the muscle and tendon you may change them but you will not affect the pain coming from the bursa.  This analogy applies to every condition.

Since 2011 when I began using FSM, back pain patients take about half as much time to recover.  I have surprised patients and myself many times, treating conditions that can otherwise be resistant, such as knee bursitis, nerve traction injuries, chronic whiplash and many more.  Micro current can people who have pelvic pain and visceral scarring–even a policeman with a gunshot wound to the flank (with chronic scarring into the viscera).  These are a few of the difficult conditions that microcurrent can help. your loss of function.  Response to active, passive, resisted and repeated motion testing is used to determine an individualized treatment.  You will learn the tools needed to correct the injury; and receive the treatment you need to support the healing process.

Treating nerve pain has always been a very difficult part of physical medicine and pain management. Frequency Specific Microcurrent (FSM) has been a remarkably effective way to treat nerve and muscle pain for over 15 years.

FSM uses frequencies from a list created by medical physicians in 1922 but applies them with a modern digital two-channel microcurrent unit instead of the antique equipment originally used. The frequency from the list said “to reduce inflammation” reduces IL-1 by a factor of 10 when applied to nervous system tissue, reduced LOX inflammation by 62% and COX inflammation by 30% in animal studies. (1,2) IL-1 is known to be associated with neuropathic pain and peripheral LOX and COX inflammation are known to increase musculoskeletal and joint pain. Micro amperage current increases ATP production by 500% in both vivo and in vitro studies (3,4,5) and applies voltage sufficient to change voltage gated ion channels and repolarize the nerve membrane.

With this tool even chronic nerve pain (6) and spinal sensitization become easy to treat. When you can treat the neuropathic component of myofascial pain and neuromuscular dysfunction, recovery becomes the expected outcome. (7,8)

David Simons, author of The Trigger Point Manual, said “FSM is a whole new approach to the treatment of musculoskeletal pain patients that is far superior to any other treatment available. This was my personal experience.”
