The 2023 Ultimate Guide to Wireless TENS Machines

Today, dealing with everyday pain or discomfort is manageable due to the comprehensive options available. People experiencing pain employ various tactics to ease their conditions. People seek medical help for the proper diagnosis and treatment for severe pain. On the other hand, home remedies or oral medicines can help reduce mild to moderate symptoms. Moreover, additional forms of pain relief include physical therapy and electrotherapy. Physical therapy involves massage, acupuncture, hot and cold therapy, and exercises, among many others. On the other hand, electrotherapy uses portable devices to aid in pain relief. Physiotherapists also recommend electrotherapy such as Transcutaneous Electrical Nerve Stimulation (TENS) to patients with chronic or acute pain. Anyone can use TENS therapy through modern devices such as a wireless TENS machine. 

TENS therapy using a wireless TENS machine is a non-invasive and drug-free pain management alternative. Therefore, people seeking natural pain relief use TENS to minimise their intake of pain medication. Additionally, doing TENS therapy is more accessible through the availability of personal devices like the wireless iTENS from iTENS Australia. This post will guide you on TENS treatment and the advantages of a wireless TENS machine. 

Why do we Feel Pain?

Firstly, knowing how and why we feel pain is essential to understand better how a wireless TENS machine works. Pain is an uncomfortable sensation often described as a deep, throbbing, pulsating, or burning feeling. Additionally, it acts as a warning signal that tells us something is wrong with our bodies. People feel pain when a signal travels through the nerve fibres in the spinal cord to the brain. In effect, the brain receives the signal and interprets it as pain. Furthermore, pain receptors called the nociceptors are found in the muscle, joints, and skin. Particularly, the skin has more receptors, so it is easy to tell the location and the type of pain.

Body pain is common and can happen at any life stage and for various reasons. It can range from mild to intense and all-over or to a specific body part. Some pain may go away without treatment, while some persist. Short-lived pain is called acute pain. It can directly result from injuries such as broken bones, wounds or cuts. When an injury or wound heals, the discomfort also disappears. In contrast, pain that is long-term or recurring is called chronic. It usually lasts at least six months due to an underlying health condition or illness. Moreover, pain may worsen if untreated and can affect everyday activities. Therefore, people seek various methods to minimise unpleasant sensations. Using a wireless TENS machine is an excellent option to help manage pain without sacrificing comfort.


What is TENS?

Transcutaneous Electrical Nerve Stimulation or TENS therapy is a treatment type intended to relieve musculoskeletal and joint pain using low-voltage electrical currents. A wireless TENS machine emits mild electrical impulses to the nerves through the skin. Additionally, external stimulation elicits a reaction from the nervous system that helps reduce pain. TENS therapy can minimise pain symptoms in two ways:

  • Pain Gate Control – the Gate Control Theory of Pain proposes that the nerve fibres in the spinal cord serve as gate controllers for pain messages. During electrical stimulation, the nerve pathways close, blocking the pain signals from reaching the brain. Therefore, when the brain receives fewer signals, it decreases the perception of pain. Setting the TENS machine to a high frequency of 50-130 Hz activates the “neural gates” to close. 
  • Natural Pain Reliever –  when we feel pain or stress, our bodies release hormones called endorphins. Endorphins are neurotransmitters created in the brain and act as messengers in the nervous system. They block the nerve cells that receive the pain signals, thus, negating the pain sensation. Their effect is similar to morphine which is an opiate pain reliever. Therefore, they are known as natural painkillers. Endorphins help relieve pain, reduce stress and anxiety, and promote pleasure. A TENS machine at a low frequency of 2-10 Hz induces the release of endorphins. 

Types of TENS Machines: Wired vs Wireless TENS Machines

A TENS machine is a compact battery-operated unit comprising a set of electrodes and remote control. Electrotherapy or e-stim devices like TENS is commonly found in physiotherapist or pain clinics to treat patients with acute or chronic pain. Professionals would position the electrode pads near the area of pain to stimulate the underlying nerves. Moreover, contemporary TENS devices have two kinds: wired and wireless TENS machines. Treatment facilities and clinics typically use conventional wired TENS units. However, modern versions like a wireless TENS machine enable individuals to treat pain in the comfort of one’s homes. The iTENS from iTENS Australia is a revolutionary wireless TENS device to help treat a variety of pain conditions.  

What are the differences between wired and wireless TENS machines? The key distinction of these devices is their electrode pad connection. The electrode pads are flat adhesive patches that stick to the affected area’s skin. A standard TENS machine uses wires to connect the controller to the electrode pads. Therefore, you need the cables to operate the machine. In contrast, a wireless TENS machine like the iTENS utilises Bluetooth-capable electrodes to enable nerve stimulation. The wireless electrode pads of iTENS sync with iOS and Android devices to access various treatment modes. Despite being more compact, the iTENS delivers stable and consistent electrical impulses as effectively as a standard TENS device. 


What Can TENS Therapy Treat?

TENS therapy is an effective technique for alleviating discomfort in most body parts. Using electricity for treatments dates back to 2500 B.C. Early medical practitioners discovered that fishes capable of generating electric shocks could help relieve pain. However, it was in the 19th century that gave rise to electrotherapy. The first TENS machine was used to test the tolerance of chronic pain patients to electrical stimulation. Although initially intended for testing tolerance, many patients said they received pain relief. Since then, TENS therapy has been used to provide therapeutic effects arising from various health conditions. Modern developments such as a wireless TENS machine enable pain management to be more convenient.  In general, TENS therapy can help treat symptoms from the following:

  • Nerve pain – also called neuralgia or neuropathic pain. Nerve pain occurs when there are problems in the central nervous system or an illness. The common conditions associated with nerve pain are sciatica, fibromyalgia, carpal tunnel syndrome, and peripheral neuropathy. 
  • Musculoskeletal pain – afflictions that affect bones, joints, ligaments, tendons or muscle. Fractures and swelling or tenderness of joints can cause severe pain. Additionally, chronic conditions like arthritis, tendinitis, lateral epicondylitis and other joint disorders cause musculoskeletal pain.
  • Muscle soreness and spasm – tension, stress, and overuse cause the muscles to stiffen and become sore. For example, muscle pain may result from exercise or periods of inactivity. In addition, muscle spasms are involuntary contractions and tightening of the muscles that cause pain. 

iTENS: The Innovative Wireless TENS Machine

Chronic pain or sudden injuries can interfere with everyday activities or routines. Many people with chronic pain use TENS therapy to relieve pain without the risk of developing adverse side effects. The mild electrical currents from a TENS machine have been proven safe and do not cause further harm. Therefore, TENS is an excellent solution to help people with chronic conditions manage pain safely and efficiently. Furthermore, a wireless TENS machine like the iTENS is a simple yet innovative device that anyone can easily use. The iTENS from iTENS Australia is a modern-day electrotherapy device that incorporates wearable technology with the effectiveness of TENS treatment.
