A pulse generator in the unit sends electrical impulses to the spinal cord, stimulating and regulating the nervous system. This treatment relieves fatigue, increases blood supply, strengthens immunity, and relieves body pain. Bionic TENS (Transcutaneous Electrical Nerve Stimulation) is used in the system, which penetrates 1.2-2 inches (3-5 cm) deep into the skin (without hurting) and specifically targets the pain points. The speed and electrical pulses can be tailored to the user's preference.
