What is Microcurrent Stimulation?
Whereas ordinary, common TENS (Transcutaneous Electrical Nerve Stimulation) devices are used for pain relief by sending a milli-amperage blast of electricity to temporarily block the transmission of the pain signal (Melzack & Wall – Pain Gate Theory), microcurrent, because of its close proximity to our own body’s level of electrical current, is thought to work on a cellular level to aid in the activation of the body’s natural self-healing process restoring electrical balance once disrupted when the body is injured at a particular site.
Microcurrent is a modality providing electricity in millionths of an ampere. It has the ability to relieve pain, increase the rate of wound healing, increase protein synthesis, stimulate the regeneration of injured tissue, stimulate lymphatic flow and relieve Myofascial trigger points. Because microcurrent is at the level of one millionth of an ampere, it is delivered on the same scale as the current the body produces on its own within each cell; it is therefore physiologic and bio-compatible.
Microcurrent is sub sensory and cannot be felt while it is being delivered because there is not enough current to stimulate the sensory receptors. Traditional electrotherapy units such as TENS, Interferential and Galvanic deliver current in milliamps, which a higher level of current. They can cause muscle contraction, severe tingling, tetanization whereas microcurrent cannot.
Microcurrent increases ATP production by 500%. ATP is the primary molecule from which our body produces energy, and it is found in every cell of all living tissue. In a study done by Ngok Cheng, M.D. entitled “The Effects of Electric Current on ATP Generation, Protein Synthesis and Membrane Transport,” it was demonstrated that ATP production increased five times with currents from 50 uA to 1000 uA. With currents exceeding 1000 uA, which is the milliamp range, ATP production leveled, and with 5000 uA ATP production was reduced. Microcurrent was also shown to increase protein synthesis and amino acid ion transport.
Microcurrent applied to injured tissue supports the natural current flow in the tissue, allowing cells in the traumatized area to regain their capacitance, or flow of electrons. Trauma affects the electrical potential of the damaged cells. The injured area has a higher electrical resistance than the surrounding tissue. This decreases electrical conductance through the injured area, and decreases cellular capacitance, leading to impairment of the healing process and prolonged inflammation. When microcurrent is applied, resistance is reduced, allowing bioelectricity to flow through and reestablish normal impedance values. This process helps to initiate and perpetuate the many biochemical reactions that occur in tissue healing.
- Helps speed the healing process both by bioelectrical means and stress reduction
- Relieves chronic and acute spinal, back & neck pain
- Orthopedic injuries and post-operative recovery times shorten
- Neuro-muscular disorders have been shown to be responsive
- Myofascial pain, tendon and ligament damage repairs more quickly
- Reduces swelling and inflammation
- Releases muscle trigger points
- Improves soft tissue regeneration
