Do the TENS devices used in physical therapy, chiropractic and pain clinics use micro currents (micro amps)?
No. These devices use much stronger currents called milliamps (currents in the thousandth of an amp range). Milliamps produce a strong, buzzing feeling and don’t produce long-lasting effects. They are so overbearing on the body’s innate electrical activity that they literally shut down some of the pain-carrying pathways in the central nervous system, thus reducing the sensation of pain.
