SONICTENS can be used as either an ultrasound machine or in combination with TENS therapy to heal pain. Ultrasound therapy uses micro-vibrations to induce deep heating in tissues, stimulating blood flow and oxygen to the painful area to accelerate healing. TENS therapy produces electrical impulses that stimulate nerves, creating a tingling sensation to block pain signals from reaching the brain while increasing the body's natural painkillers. Using both ultrasound and TENS together promotes even faster healing and better results than using either individually.
