How the technology works: The device sends out a series of signals through the skin and measures the response. The body can get accustomed to a chronic condition, which may have been caused by injury, disease or toxicity. The C-fibers, which comprise 85% of all nerves in the body, react most readily to the electro-stimulation and are responsible for the production of neuro-peptides and other regulatory peptides. The peptides produced last up to several hours, meaning the healing process will continue long after the treatment is over.
