The Impulse TENS D5, dual channel digital TENS device, incorporates a "Clam Shape" design that when closed, covers the LCD screen and control buttons. The inside flip top cover includes an instruction diagram to guide the user through five modes of operation; constant, width modulation, rate modulation and two different types of burst. A timer allows the patient to use the device for a specified period of time and a low battery indicator light illuminates when the AA batteries need to be changed. If the device is not correctly attached to the patient, the amplitude does not increase. The waveform is symmetrical, biphasic square wave with adjustable pulse rate and pulse width. Measures 4.2" x 2.9" x 1.4" (10.7cm x 7.4cm x 4cm) and weighs 3.35 oz (94.97 grams). Includes carrying case, 2 AA batteries and instructions. 3-year limited warranty.
TENS (Transcutaneous Electrical Nerve Stimulator) is a type of electrotherapy equipment that works by sending small electrical pulses through the skin via ten unit electrodes to the underlying peripheral nerves. TENS is thought to work in two ways. First, "high frequency" continuous, mild, electrical activity blocks the pain signal traveling to the brain. Brain cells perceive pain. If the pain signal does not get through to the brain, the pain is not "felt." The second way is by stimulating the body's own natural pain-control mechanism. "Low frequency" or short bursts of mild electrical activity cause the body to release its own pain easers called beta endorphins. Ask your doctor or clinician for more details on this type of electrotherapy equipment.
