If your doctor has prescribed Transcutaneous Electrical Nerve Stimulator, or TENS, units for relief from chronic pain, look no further than OTC Wholesale's TENS Unit Pain Relief Center for all of the devices and accessories you need. These units send electrical impulses directly to your nerves, which help modify the perception of pain, particularly when it comes to back, foot, shoulder and neck pain. TENS units are typically used for joint or muscle pain, but are also sometimes associated with the treatment of pain associated with nerve problems. OTC Wholesale has all the pain relief products you need, including nerve-stimulation options. We also carry superior quality Muscle Stimulators, TENS Electrodes, Portable Ultrasound Units, and other TENS Unit Accessories at the lowest prices on the net.

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drugfree method of controlling pain. TENS Units use tiny electrical impulses sent through the skin to nerves to modify your pain perception. The main use of a TENS machine is for pain relief, particularly in the case of chronic pain. It is most often used for joint or muscle pain that won't go away, but can also be used to help treat nerve problems without resorting to drugs. It isn't uniformly effective, that is, different people will have different results. For some, TENS electrical pulses interrupt the pain signals so effectively that they are literally without pain. For others, the relief is nearly non-existent, but most commonly, this treatment provides considerable relief from the chronic pain that haunts the user.When the TENS Unit overrides the pain signal, it "tricks" the brain into thinking their is NO PAIN. TENS Units provide relief with nerve stimulation for back pain, foot pain, shoulder pain, neck pain, and virtually any other acute or chronic pain. How does a TENS Unit help pain? Two small electrodes that are placed on either side of the area where the pain originates. The higher frequencies tend to block the pain signals, while much lower frequencies will stimulate the body to produce endorphins which naturally reduce pain. When the TENS Unit overrides the pain signal, it "tricks" the brain into thinking their is NO PAIN. TENS Units provide relief with nerve stimulation for back pain, foot pain, shoulder pain, neck pain, and virtually any other acute or chronic pain. What is the difference between TENS and Muscle Stimulation? The main difference between the two is that a muscle stimulator is used to cause muscle contraction, while TENS focuses on nerve stimulation and tries to avoid contracting the muscles. Both use electrical pulses to do their job, but have different purposes. Muscle Stimulation is a very similar machine to the TENS, also using two electrodes to send electrical pulses through the body. However, the purpose is quite different. Here, the purpose is to cause the muscles to contract and the reasons have nothing to do with pain relief. Both TENS machines and muscle stimulators have their uses, but they are very different in their reasons for being used. If you are looking for an alternative to standard pain relief, then the TENS machine is what you should be looking at. However, for the prevention of atrophied muscles and to define specific muscle groups, the muscle stimulator is the way to go. What does Single, Dual or Quad Channel mean? Generally, the TENS or muscle stimulator signal is between two electrodes or on a single channel. Therefore, the user can apply electrode stimulation to one site per channel. A dual channel device allows for stimulation in two locations using 4 electrodes and a quad channel device can use up to 8 electrodes. It is not necessary to use all of the channels available on a device, but each channel requires a pair of electrodes. The modes of the device refer to preset stimulation effects with changes to pulse rate, pulse width, modulation, frequency and sometimes amplitude. These modes are sometimes programs that start off at a certain rate and then proceed to other modes of stimulation. The purpose of these modes are to help the user quickly and effectively apply a therapy that is suitable for an individual complaint. Stimulation can be very specific to an area of the body and the cause of the pain. For instance, the Ultima 20 mode device has specific mode setting for Neck, Torticollis, Low Back, Sciatica, Epicondylitis, Wrist Pain, Post-Surgery knee pain, Ankle sprain, Knee pain, Hip pain, Menstrual pain, and Neuralgia, as well as, 8 additional preset modes. How are IF Units and Galvanic Units different from TENS Units? Interferential Stimulation differs from TENS because it allows a deeper penetration of the tissue with more circulation and comfort.
Interferential Stimulator (I.F. Unit) is used to treat, relieve and manage chronic pain. It can also be used as adjunctive treatment in the management of post surgical and post traumatic acute pain. Interferential Units provide deeper stimulation that traditional TENS Units. Galvanic stimulation is most useful in acute injuries associated with major tissue trauma with bleeding or swelling. In contrast to TENS and IF units, which apply alternating current, galvanic stimulators apply direct current. High-voltage Pulsed Galvanic Stimulation (HVPGS) is being used for wound healing, edema reduction and pain relief carpal tunnel syndrome and diabetic neuropathy are examples of where galvanic stimualation is used. Direct current creates an electrical field over the treated area that, theoretically, changes blood flow. The positive pad behaves like ice, causing reduced circulation to the area under the pad and reduction in swelling. The negative pad behaves like heat, causing increased circulation, reportedly speeding healing. Why use Silver Electrodes instead of Electrodes? Silver Electrodes refer to carbon electrodes that include a thin layer of silver between the pad and the backing where the actual wire connection is made. This silver forms a better connection between the wire lead and the electrode, and distributes the electricity more uniformly across the pad. Silver Electrodes are slightly more expensive to produce, but they are substantially more effective at delivering the electrode stimulation treatment to the effected site. Whether you are using a TENS unit, Muscle Stimulator, Interferential unit or a Galvanic unit, you will get a lot more out of it using a silver coated electrode. |
