Frequency-Specific microcurrent (FSM)


Frequency-specific microcurrent (FSM) is a non-invasive method of pain management that employs low-level electrical currents. This technique targets specific body tissues to alleviate pain caused by various conditions or injuries. By adjusting the frequency of electrical pulses, FSM aims to reduce inflammation, promote tissue repair, and provide pain relief.

Reasons for undergoing the procedure

The following conditions are among the most common for which FSM is used to treat pain, particularly pain from the nerves and muscles, inflammation, and scar tissue:

  • Acute and chronic musculoskeletal injuries.
  • Acute and chronic neuropathic pain.
  • Arthritis.
  • Asthma.
  • Burns.
  • Chronic fracture and bone pain.
  • Concussions.
  • Diabetes-related neuropathy.
  • Fibromyalgia.
  • Headaches.
  • Irritable bowel syndrome.
  • Kidney stones.
  • Neuromas (overgrowth and nerve scarring following an injury).
  • Plantar fasciitis (heel and foot pain).
  • Shingles.
  • Spinal injuries.
  • Sports injuries.
  • Tendinopathy (tendon inflammation and/or swelling)
  • Torticollis (the head is tilted to one side).
  • Viscerally-referred pain.
  • Wounds.


Particular individuals should not be treated with FSM, this includes the following:

  • Those who experience uncontrollable seizures.
  • Those who wear pacemakers.
  • Those with implanted pumps.
  • Those women who are pregnant.

Additionally, in cases of acute fractures, new scar tissue (within six weeks), and acute infections, certain frequencies should not be used. Before receiving any kind of treatment, make sure to discuss any of these worries with your healthcare provider.

Treatments for FSM frequently result in extremely minimal and minor side effects. You may experience nausea and drowsiness as a side effect of the procedure.


Your healthcare provider will use a specialized device to apply a small electrical current to specific parts of your body as part of your FSM treatment. One millionth of an ampere is the small electrical current employed in this procedure. Electrical current in such small amounts is safe.

Certain frequencies will be chosen based on the type of tissue in order to promote the body’s natural healing process and lessen the pain. Almost every kind of tissue in your body has a certain frequency.

Your healthcare provider will first choose which frequencies will be used for your specific condition during your FSM treatment. A common practice is to adjust the frequencies to two distinct levels. For instance, one microcurrent channel may be set to 10 Hz, while the second may be set to 40 Hz. Usually, skin patches or a towel moistened with water are used to apply the current. It’s important that you drink enough of water prior to your FSM treatment.


Frequency-specific microcurrent (FSM) treatment can lead to lasting pain relief, which may persist for several days or longer, depending on the severity of the condition. It is particularly effective for acute injuries, offering a non-invasive and often pleasant experience. The low-level currents used in FSM are typically imperceptible to patients. During treatment, you may notice a gentle warming and softening of the affected tissues.

One of the mechanisms through which FSM operates is by potentially increasing ATP production in injured tissues. ATP is crucial for cellular functions throughout the body. FSM therapy may enhance ATP production by up to 500% in damaged cells, aiding in the healing process. Additionally, FSM treatment can help alleviate muscle stiffness and pain by promoting tissue relaxation.
