Best TENS Unit for Back Pain 2022 – Device Types

Individuals should consider the different device types while looking for the best TENS unit for back pain 2022. TENS units are typically composed of electrode pads and a control unit. The electrode pads deliver low-voltage electric currents, while the control unit allows the user to adjust the output. Generally, there are two types of TENS machines: wired and wireless.

Wired or handheld units are often seen in hospitals and pain clinics. These use lead cables to connect the electrodes directly to the control unit and power supply. Many value them for the high levels of power they can send. They can have single, dual, or four channels.

Meanwhile, wireless TENS machines utilise Bluetooth to link the electrodes to the controller. The electrodes may link to a specialised device controller or a smartphone application for wireless units. Many value them because they use advanced technology to enhance the convenience of using TENS. Although some units may cost more than handheld types, wireless machines can be more cost-effective in the long term.

Wireless machines have several advantages over their traditional counterparts. Firstly, wireless machines allow users more freedom to move because of the lack of cables. This is ideal for those with active lifestyles or those who wish to do simple activities. It also requires less set-up time since the electrodes can quickly connect via Bluetooth.

Secondly, wireless devices may offer the user a wider selection of preset modes. This makes it more convenient for people who wish to quickly soothe their pain without adjusting the settings manually. Lastly, wireless units offer more varieties of pad shapes and sizes.
