Frequency Specific Microcurrent (FSM)

In 1946, an Osteopathic Physician named Harry Van Gelder discovered the beneficial health effects of using microcurrent frequencies to heal the body. Gelder utilized a machine which emitted microcurrent frequencies and combined it with other conventional therapies to treat patients successfully. Since then, more advanced FSM machines using two-channel microcurrent frequencies have been developed with even greater healing effects.  

FSM uses low-level electrical currents to treat pain and other health conditions. Frequencies are simultaneously applied using two channels so they intersect or cross in the area to be treated. Both frequencies are accurately placed on the body to reflect the condition being treated and the tissue being affected.

How Does Frequency-Specific Microcurrent Work?

FSM is applied to the body with a device that delivers a mild current. Microcurrent is an extremely mild electrical current (one millionth of an ampere). The human body actually produces its own current within each cell.

In FSM, depending on the tissue involved, specific frequencies are selected to encourage natural healing of the body and to reduce pain. Frequencies have been identified for nearly every type of tissue in the body.

One of the ways FSM works is by potentially increasing the production of the substance ATP in injured tissues. ATP is the major source of energy for all cellular reactions in the body. Because treatment with FSM can increase ATP production by as much as 500% in damaged tissues, this may help with the recovery process. Depending on the condition, treatment with FSM can “loosen” or soften the muscles, which can help relieve pain and/or stiffness.

What Conditions Can Be Treated With FSM?

FSM is most often used to treat pain, especially nerve and muscle pain, inflammation, and scar tissue, from the following conditions:

  • Shingles
  • Burns
  • Kidney stones
  • Asthma
  • Irritable bowel syndrome
  • Disc injuries
  • Fibromyalgia
  • Diabetic neuropathy
  • Neuromas (overgrowth and scarring to a nerve after an injury)
  • Tendinopathy (inflammation and/or swelling of the tendon)
  • Acute (sudden) and chronic (long-term) musculoskeletal injuries
  • Acute and chronic neuropathic (nerve) pain
  • Chronic fracture and bone pain
  • Arthritis
  • Torticollis (the head is tilted to one side)
  • Disc injuries/discogenic- and facet-based pain
  • Viscerally-referred pain
  • Concussions
  • Headaches
  • Plantar fasciitis (pain in the heel and foot)
  • Sports injuries
  • Wounds

Is Frequency-Specific Microcurrent Painful?

Treatment with FSM is non-invasive and painless. The currents used in FSM are so low that the patient often does not feel them. During FSM treatment, patients may notice certain effects, including warmth and a softening of affected tissues.

How Is Frequency-Specific Microcurrent Applied?

To treat a patient with FSM, the caregiver first sets the frequencies to be used for that particular condition. In many cases, the frequencies are set at two different levels; for example, one microcurrent channel might be set at 10 Hz, and the second at 40 Hz.

The current is most often applied with a moistened towel or with skin patches. It’s very important for the patient to be well hydrated (drink plenty of fluids) before FSM treatment.

How Long Do The Effects of an FSM Treatment Last?

Depending on the condition and the patient’s level of pain, the effects of an FSM treatment for pain can last several days or longer. For acute injuries, lasting pain relief can often be achieved.
