Electrical stimulation in low voltage is what the TENS machine uses through the electrodes that are hooked to the device to obstruct the pain signals from going to the brain. The best TENS unit can be purchased from your local pharmacies, medical supply stores and online retailers. The device is an OTC (over the counter) item, so you can buy it even without a doctor’s prescription. However, because some insurance companies require a prescription in order to cover the cost of a TENS machine, it will be to your benefit if you ask your physician to issue a prescription for this product.

Finding the best TENS unit for your particular condition is not a difficult thing. You just need to check with your physical therapist or doctor the features of the TENS machine that you need, so you can get favorable results from the therapy. The battery life is one feature that you should look into when looking for the best TENS unit. If you choose a cheaper unit, it is very likely that the battery that comes with it is a regular disposable battery, which easily wears out with use. A higher priced TENS has a rechargeable battery which offers savings, because you just need to recharge, not buy a new battery.

The next feature of the best TENS unit is to check is the control. If you have a condition that affects your ability to use your hands, or you have arthritis, you might find it difficult to operate the small buttons and knobs of the TENS machine. You may want to buy your unit from your local store, rather than online, so you can try touching the buttons to be sure that you can turn them on and off very easily.

The width control is a feature that enables you to determine the level of pain relief that you get from the device. The width control also tells you how long the TENS device stays on before it is set off. Choose a device with simple settings; one that allows you to adjust the width control, not the type that is used in doctors’ clinics. Some features may not be necessary for your home use.

Next is the warranty. Most TENS devices are affordable, and because they are such, it will not mean that you would not need any warranty for these. The Transcutaneous Electrical Nerve Stimulation unit is a major electronic that is purchased, so you should check all warranties and compare them before buying. This will allow you to get your money’s worth. If your machine does not have a warranty, you may end up shelling out big money when replacement parts or repairs become unavoidable.

If possible, look for a company that will allow you to try their TENS devices in your home for a limited period. Trial is an ideal way to determine if a machine suits your pain relief needs, because different machines have different key features, electrode set ups, and intensity levels. If you are not allowed a trial, then make sure that you read and understand the company’s return policy, so you can send back the machine without hassles if it does not work for you.
