A TENS unit is battery-powered, medical-grade, disposable electrodes that deliver a low-voltage electrical current directly to the affected area. When applied to the skin, they excite nerves to decrease inflammation and pain. There are various basic TENS unit characteristics that give the greatest flexibility and functionality for various applications:

Treats multiple body areas

TENS electrodes are available in sizes to treat various body parts, such as feet, hands, legs, elbows, shoulders, elbows, and back. For maximum relief, choose a size that will cover the largest area possible. The best tens unit for an individual’s particular condition and needs should be customized with the patient’s age, weight, gender, health status, desired relief level, desired use, and personal preferences. For example, younger and older people may prefer a smaller, lower-profile unit that is easier to access; a stronger, larger unit may be needed for a person with arthritis.

Dual-channel operation

Some TENS units offer dual channels, meaning that they can be used in one hand and taken in the other. This capability allows for greater dexterity and comfort, as well as dual-frequency operation. Dual-frequency TENS provides higher overall stimulation and faster pain management than monocular or inter-firing modes.

Easy application and removal

The convenience of quickly and easily applying and removing a TENS unit makes it an ideal choice for many types of therapies, including electrotherapy. These units can be worn like any other piece of clothing and can be carried around discreetly. They are small enough to easily fit in the pocket or purse and are not very bulky, making them easy to transport or place in the office. Many Electrotherapy devices also come with their own charger and cables, making the application process simple and quick.

Ease of use and comfort

The ease of use and comfort of TENS is reflected in its price. Many models can be purchased at a reasonable cost, making it an affordable treatment option for the everyday user. Most units also come with replacement pads and electrodes, so users do not need to worry about buying new units every day.

Versatility

There are many different types of TENS units available on the market. For example, there are stimulator based units that are more suited for muscle and joint pain relief, or there are topical applications that work to reduce inflammation, itching, and dilation. A person can choose which modes he or she wants to use based on his or her specific needs. This ease of use and versatility makes the TENS unit a popular choice.
