What to Look for When Buying a TENS Unit?

TENS therapy is a non-invasive and drug-free method of alleviating various pain conditions or disorders. People may know about TENS or Transcutaneous Electrical Nerve Stimulation after sustaining an injury or post-surgery. Likewise, people with chronic ailments learn about TENS to help minimise discomfort without medicines. In addition, physiotherapists may recommend TENS to help patients manage pain at home. Therefore, people may ask what to look for when buying a TENS unit. A TENS machine is a portable device utilising electrode pads to deliver mild electrical currents. There are many kinds of TENS machines on the market, and looking for the best TENS unit may be overwhelming. Fortunately, iTENS Australia offers the revolutionary iTENS, a modern TENS device with wireless features. 

TENS therapy is a self-administered pain treatment using a portable TENS device. People new to TENS therapy can quickly learn how to use the device through its simple instructions. It also enables them to control the level of pain relief through adjustable settings. Therefore, it is safe for use without medical supervision. However, it is best to consult your physician on the proper use of TENS for your specific condition. Additionally, this post will guide you on what to look for when buying a TENS unit. 

What is a TENS Unit and its Functions

It is vital to know how TENS works before discussing what to look for when buying a TENS unit. TENS is a type of electrotherapy specifically stimulating sensory nerves to relieve pain. The electrode pads are placed on the skin, allowing the flow of mild electrical currents to the body. Next, it elicits a response from the central nervous system to minimise pain or discomfort. TENS help manage uncomfortable sensations through two main functions: Gate Control and Endorphins Release theories. According to the Gate Control Theory of Pain, the spinal cord has a bundle of nerve fibres that control pain signals travelling to the brain. During a high-frequency TENS (50 to 100 Hz), it stimulates the “neural gates” to close, blocking the pain signals from reaching the brain. Meanwhile, low-frequency TENS (2 to 10 Hz) induces the release of natural painkilling chemicals called endorphins. 


What to Look for When Buying a TENS Unit

TENS machines come in various shapes and sizes. However, when examining what to look for when buying a TENS unit, it should have the basic features, like treating multiple body pain areas and built-in programs. Moreover, some devices may have more features than others. Furthermore, the following are essential guidelines for choosing the most suitable device:

  • Wired or wireless – standard TENS units use wires to connect the electrode pads to the controller. Meanwhile, a wireless unit like the iTENS utilises Bluetooth-capable electrodes to deliver efficient pain relief. 
  • Intensity levels – multiple intensities help relieve different pain conditions. For example, high pulse rates are suitable for intense pain. Meanwhile, low intensity is best for mild symptoms or boosting blood circulation. 
  • Pre-set modes – TENS machines come with built-in programs for quick administration. The settings are fixed, so you do not need to adjust them manually. Before buying a TENS unit, you may check how many pain modes are available. The iTENS app features numerous programs for different body areas or health conditions. 
  • Pad options – the TENS pads come in different shapes and sizes, from small to large. Using the right electrode pads is vital for effective treatment. For example, small pads fit tight joints, while larger pads can cover broad areas like the back. 
  • Other features – a wireless TENS device has additional functions like tracking usage, letting you manage pain more efficiently.

  • You may also customise the TENS treatment by manually adjusting the frequency, duration, and waveforms.
  • The device produces mild tingling sensations as the stimulation begins. 
  • You may adjust the intensity to the level where you feel most relieved. However, avoid turning it too high that it makes you feel uncomfortable.
