Frequency Specific Microcurrent (FSM) is a type of electrical therapy that uses low-level electrical currents to treat pain and other conditions. It's a non-invasive procedure where specific frequencies of microcurrent are applied to targeted areas of the body to promote healing and reduce inflammation. FSM can be used to treat a variety of conditions, including pain, inflammation, and scar tissue.

Here's a more detailed explanation:

  • Low-Level Current:

    FSM uses microamperes of electrical current, which is significantly lower than other electrotherapy methods like TENS units. This low-level current is designed to interact with the body's natural electrical activity and promote cellular healing. 

  • Frequency Specific:

    The key aspect of FSM is that it uses specific frequencies of microcurrent tailored to the condition being treated. Different frequencies can target specific tissues and cellular processes, allowing for a more precise and effective treatment. 

  • Application:

    FSM is typically applied using moistened towels or skin patches, with conductive gloves or other conductive materials. The practitioner sets the appropriate frequencies for the condition and applies the current to the targeted area. 

  • Mechanism of Action:

    FSM is believed to work by increasing cellular energy production, reducing inflammation, and promoting tissue repair. It may also affect endorphin release and other biochemical processes to help alleviate pain. 

  • Applications:

    FSM is commonly used to treat nerve and muscle pain, inflammation, and scar tissue, as well as conditions like fibromyalgia, diabetic neuropathy, and sports injuries. It can also be used to promote healing after injuries or surgeries. 

In essence, FSM is a form of electrical therapy that uses low-level, frequency-specific microcurrents to target specific areas of the body, aiming to promote healing, reduce pain, and improve overall well-being.
