How the Best Portable TENS Unit Works?

The best portable TENS units are completely wireless ike those that iTENS Australia offers. These units consist only of the electrode pads, each of which has its power supply. The pads are adhesive on their own, which means that you can place them directly on the skin without any additional tape or gel. Once you place the pads on the skin, you can begin the treatment.

Therapy sessions are controlled via the Bluetooth app on a smartphone. In the app, you can control TENS settings, like intensity levels and duration of sessions. This allows each person to easily customise how they conduct their therapy sessions. The minimal amount of equipment also makes it easy to carry and set up. Essentially, all it takes to start is putting on the pads and taking out your phone.

The electrical pulses TENS uses are very low power. This means that it does not affect the body outside of the intended pain relief. Furthermore, you can use TENS therapy while doing other activities without it getting in the way or distracting you.

Wireless vs Wired Unit

TENS machines are categorised into two types – wired and wireless. The wired unit has a separate control unit that connects to the pads via cables. The pads for these types tend to be lighter, but the device is less mobile than wireless.

The recommended type of unit is wireless. It offers dual modes through direct and app modes. The unit has pads with their power supply and a wireless connection to the control unit. This is usually a Bluetooth connection to a smartphone. A person can therefore control the therapy session via an app on their phone, giving them maximum control over it.

Guidelines of the Best Portable TENS Unit

Since the best portable TENS unit is wireless, it is a lot much easier and more convenient to use. Through the smartphone app, it is easier to operate. Firstly, you may start the app by selecting the treatment depending on your condition.

Secondly, you may set the frequency, pulse rate, intensity, and time. The app allows user-defined manual settings for more efficient use. Furthermore, the iTENS electrode pads are light and slim. The wing-like pads are more flexible which can reach other parts of the body that are difficult to reach. For example, small wing pads are suitable for your ankle, whereas large wing pads are for your back.

Lastly, you can conduct TENS therapy as often as you like. It is recommended to perform self-treatment for 20 – 30 minutes per session and about 2-3 times a day. Excessive use of the device will cause skin irritation and mild rashes. Therefore, you should give yourself a break or rest for at least 20 minutes in between sessions. 

Safety Guidelines in Using TENS Machine

While using TENS, be sure to remember the basic safety guidelines. Do not place pads over sensitive areas. This includes wounds, the temples, the spine, and joints. If you have a heart condition, do not put pads on your chest, and consult with a doctor before using it.

The most common side effect of TENS is occasional mild skin irritation. This occurs when TENS is used repeatedly in the same spot. To avoid this, be sure to wait at least 20 minutes between therapy sessions. If you notice your skin starting to hurt or turn red, try moving the pads to a different location.
