Everyone will suffer muscle pain at some point in time, but for millions of Americans, that pain is chronic and they feel it everyday. For those with chronic pain, simple stretches and aspirin are just not enough. You may be prescribed a stronger medication, but they can often be addicting or your body can gain a tolerance to it after high usage. An alternative for pain relief is a TENS Unit, also known as Transcutaneous Electrical Nerve Stimulation. This device has proven useful for many patients, but if you've never purchased one before, you might not know what features to look for.
Better TENS Units offer you great leeway with pulse rate, pulse width, and frequency. By changing these, you can control how much stimulation is sent to the affected area. Changing these rates can help you find the perfect amount of electro-therapy in order to relieve your pain. To make it easier, most TENS Units come with several modes, or preset rates and frequencies. By using modes, you can save yourself the trouble of figuring out which combinations work the best. If you experience pain in several areas of your body, you'll want a unit that has a handful of modes. Some are dedicated to lower backs, neck pain, knee pain, etc. Having a variety of these modes can be very effective, so the more the better.
Another feature to consider is the number of channels. The more channels you have, the more areas you can use the machine on at once. A single channel can receive a signal from two electrodes. A dual channel means you can use four electrodes in two locations, and so on. However, if your pain is limited to a small area, then don't feel that you need a quad channel unit.
Battery power also needs to be factored into your decision. Does the TENS Unit require a normal alkaline battery or does it come with a rechargeable battery? Rechargeable batteries are ideal, but if you're taking your unit on the go and it runs out of power, then you'll wish you had replaceable batteries. Will you be needing to transport this unit? Are you taking it with you to a physical therapist or is it simply for home use? Many brands make excellent portable devices, some small enough to fit in the palm of your hand. Most come with a carrying case and reusable electrodes, but it never hurts to double check.
You might be tempted to go for "bigger and better," but you need to consider your needs versus extreme power. Modes and channels are what you want to look at first, everything else is just an awesome bonus!
