Microcurrent therapy uses extremely low levels of electrical current to support the body’s natural healing process. Because the current mirrors the scale of the body’s own bioelectrical signals, it can help injured tissue repair, reduce inflammation, and accelerate recovery, usually without the patient feeling anything at all.
What Is Microcurrent Therapy?
Microcurrent therapy delivers current measured in microamps, or millionths of an amp. For comparison, a TENS unit used for pain relief operates in milliamps, roughly a thousand times stronger. TENS works by overriding pain signals and creates a noticeable tingling. Microcurrent works at the cellular level and is typically below the threshold of sensation.
Frequency-specific microcurrent (FSM) is a specialized form of microcurrent that pairs low current with specific frequencies selected for the condition and the tissue being treated.
How Microcurrent Stimulates Tissue Repair
Increasing ATP Production
Adenosine triphosphate (ATP) is the energy molecule cells use to repair and rebuild. A frequently cited 1982 study by Cheng and colleagues found that low-level microcurrent increased ATP production in tissue by up to 500%, while higher currents reduced it. More cellular energy supports protein synthesis and the transport of nutrients and waste, both essential for healing.
Restoring the Body’s Electrical Signals
Injured tissue generates its own small electrical current, sometimes called the “current of injury,” which helps direct repair. Microcurrent is thought to reinforce these signals, supporting organized cell migration and tissue regeneration.
Reducing Inflammation
Inflammation is necessary for healing, but when it lingers it slows recovery and increases pain. Microcurrent therapy is used to help calm prolonged inflammation and reduce swelling, allowing the repair phase to proceed.
Who Benefits From Microcurrent Therapy?
Microcurrent therapy is commonly used for:
- Soft tissue healing: sprains, strains, and tendon and ligament injuries
- Post-injury and post-surgical recovery
- Muscle recovery after intense training or competition
- Overuse injuries such as tendinopathy and plantar fasciitis
- Nerve pain and neuropathy
- Chronic pain conditions such as fibromyalgia
- Wound and scar tissue management
Microcurrent vs. PEMF Therapy
Pulsed electromagnetic field (PEMF) therapy uses magnetic fields to induce small currents in the body, while microcurrent applies the current directly through pads or probes on the skin. Both aim to support cellular function and healing. Microcurrent, and FSM in particular, allows the practitioner to target specific tissues and conditions with defined frequencies.
What to Expect During Treatment
Treatment is painless and relaxing. Pads are placed on the skin around the treatment area, and sessions usually last 30 to 60 minutes. Many patients notice reduced pain or improved mobility within the first few sessions, though the number of treatments depends on the injury and how long it has been present. Microcurrent is not used during pregnancy or in patients with pacemakers or implanted electrical devices.
Frequently Asked Questions
What does microcurrent therapy do?
Microcurrent therapy uses very low electrical current to support cellular energy production, reduce inflammation, and help injured tissue heal faster.
Does microcurrent reduce inflammation?
Yes. Reducing prolonged inflammation is one of the most common reasons microcurrent is used, particularly after injury or surgery.
Is microcurrent therapy the same as TENS?
No. TENS uses stronger current to block pain signals. Microcurrent uses current about a thousand times lower to support healing at the cellular level.
