The ArthroStimâ„¢ is an FDA approved instrument developed by IMPAC technology in Oregon. It introduces energy/force/information to the body to realign segments and remove nerve pressure at a speed of 12 “taps” per second (12 hertz). It is a fast, accurate, low force and controlled adjustment. The ArthroStimâ„¢ gives patients a very specific adjustment, meaning that only the segment that is out of position is adjusted; there is no twisting, turning or “cracking” of joints. This technique permits adjusting in different postures.
