Which TENS Unit is the Best?

The best TENS unit is the one that provides relief for your particular pain on a regular basis, as well as the one that is within your financial means. It’s as simple and as complex as that; there are no right or wrong answers that fit all cases. That is why most TENS devices feature multiple treatment modes; as few as three, as many as ten. Your doctor may preset your machine’s settings based on his knowledge of your condition and history, and though those settings may be locked in place, they may also be adjusted to yield better results. In other words, there is a bit of trial and error. 
Fortunately, in general it is not so much a matter of which TENS unit is the best to relieve your pain, but more of what intensity and length of treatment is more suited to your type and source of pain. Taking into account all of the facts, you and your doctor may be able to choose beforehand the model that will eventually better fit your needs. The principle of TENS is rather the same for all units, which is the delivery of pain soothing electrical impulses through the skin and to the nerves, via electrode pads and lead wires.

However, there are other factors that may influence your decision, and which are all up to you. For example, if you are going to sit still at home for the application of TENS, then you could use the somewhat bulkier (in comparison to other units) TENS 3000. On the other hand, if you need or want to be moving around during application, or are constantly traveling and require to bring pain relief with you anywhere you go, then lightweight devices are more recommendable, such as the TENS 7000, the TENS AA Digital Unit, or the Ultima 3T.
Price also plays a part in deciding which TENS unit is the best. Although most devices are reasonably priced, the difference in price between one and another may sway your judgment as a consumer. For instance, the TENS 7000 may be around $10 more expensive than the TENS 3000 (once again, we use the word expensive only as a way of comparison). Hence, you might prefer a previous model with a lower price tag. As a result, even though most people might consider the newest product to be better, it would be the other way around for you. And as long as it works for you, both practically and cost-wise, it will be better.
