TENS therapy is a great way to realize drug-free pain relief. If this is an option your physician has advocated for you to perform at home, or you're interested in the potential this pain relief treatment holds, OTC Wholesale has everything you need to get started. Once you have a TENS unit, browse our inventory to find all the right TENS accessories for your unit. We even make it easy to shop by choosing from economy, standard and premium electrodes. Like anything, the higher the quality, the longer the electrodes will typically last. But no matter which option you choose, you can be certain you're getting the best price from OTC Wholesale.

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 affected site.
Results of a dispersion test on Silver Electrodes vs. Carbon Electrodes will show a much greater dispersion area with more intensity on the silver coated electrode.
Our silver electrodes also use copper lead wires with special heads that help promote greater dispersion and prevent the wire from pulling out. You simply cannot buy a better TENS Unit Electrode!
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 silver coated electrodes.
Many clinical therapists recommend foam backed electrodes when the treatment is combining hot and cold therapies with electrode stimulation. The foam backing repels moisture created by the treatment and adds insulation between the external therapy and the electrode pad. Many of our customers prefer the foam backed electrodes for their smooth touch and flexibility, though they are somewhat more high profile than the mesh backing. Mesh or cloth backing is generally slightly more flexible than their foam backed counterparts.
We select all of our electrodes from reputable suppliers and most of our electrodes feature a brand name or an American made gel for maximum reusability. This adds a slightly higher cost to the manufacturing process and to the price of the electrodes. There are less expensive electrodes available using a foreign made adhesive and we are currently testing their reusability to make sure it meets our standards. Some of our economy electrodes use a foreign made gel and feedback has been very good.
We recommend that you purchase our Essential TENS Care kit with your electrodes. View this short video describing the proper care and usage of your electrodes:
Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drug free method of controlling pain. TENS Units use tiny electrical impulses sent through the skin to stimulate the nerves and modify 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. Different people will have different results. For some, TENS electrical pulses interrupt the pain signals so effectively that they are literally without pain. Others may experience different levels of relief. However, in most cases, there will be some degree of relief from chronic pain. The TENS Unit overrides the pain signal by "tricking" the brain into thinking there is no pain. TENS Units use nerve stimulation to provide relief from back pain, foot pain, shoulder pain, neck pain and virtually any other acute or chronic pain.
Two small electrodes 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 there is no pain. TENS Units use nerve stimulation to provide relief from back pain, foot pain, shoulder pain, neck pain and virtually any other acute or chronic pain.
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.
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.
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.
