The AuraWave® is the first FDA-cleared Class II medical device available without a prescription for treating pain in the lower back and extremities with TENS technology. Simply place the AuraWave® electrode pads over your area of pain, select the setting that's right for you, and stop your hurt where it starts! The AuraWave is equipped with six manual modes that deliver specific treatment techniques and four automatic modes that have been specially calibrated, using a series of pre-programmed pulses, to optimally deliver therapeutic results - ranging from soothing relaxation, to deep-tissue stimulation, to invigorating muscle-building. Much like pain, all people are different. Being able to not only choose from the 10 preset modes, but also from 10 levels of intensity, allows users to customize their pain treatment to their pain levels!Complete AuraWave Pain Relief Package Includes:?
