What is FSM?

FSM for Pain and Tissue Repair

Frequency-specific microcurrent (FSM) is a technique for treating pain by using low-level electrical current. The current is delivered to certain parts of the body in an attempt to relieve the pain.

A frequency is the rate at which a sound wave or electronic pulse is produced. This measurement is registered in hertz (Hz). In using FSM to treat pain, it’s been found that various frequencies can be used to potentially reduce inflammation (swelling), repair tissue, and reduce pain.

How does frequency-specific microcurrent work?

FSM uses Ultra low current and increases ATP

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.

Who Should NOT use FSM?

DO NOT use FSM if:

  • Pregnant

  • Infection

  • Uncontrolled Seizures

  • Implanted Pacemakers or pumps

Be Wary if​

  • Recent Cut or Fracture

People who should not receive FSM treatment include those who have pacemakers, implanted pumps, or uncontrolled seizures, and women who are pregnant.

In addition, certain frequencies should not be used in cases of acute infection, new scar tissue (within 6 weeks), and acute fractures. Please discuss any of these concerns with your provider during consultation so that appropriate recommendations can be made.

How Often? or What is the FSM Committment?

Please try to attend FSM 2 times a week for 4 to 6 weeks.

Chronic Musculo-Skeletal issues are established over a period of time.

Acute issues are due to an injury to trauma.


You MAY have both!  "The straw that broke the Camels back." is a common phrase and applicable in movement issues. A tired, dehydrated, undernourished body is more prone to injury than a well cared for body.


Experience over the decades of use by practitioners indicates that the best outcomes are when the client can attend an FSM session 2 times a week for 4 to 6 weeks.  Often results take less time. 


Each person is different in the layers of causal impact, ability to heal, and foundations for health.

Most therapies for health and healing similarly recommend intensive participation early in treatment, with potential to adjust later.
