TENS (Transcutaneous Electrical Nerve Stimulation) units have gained popularity in Australia as a non-invasive and drug-free way to manage pain. These portable devices deliver low-voltage electrical currents through electrodes placed on the body. When these currents reach the nerves, they disrupt pain signals, leading to alleviation of symptoms. It also helps release natural painkillers called endorphins, providing further relief. People can buy TENS units in Australia to manage acute and chronic pain.
People with pain conditions may experience diminished quality of life and limited mobility. It can impact daily activities, such as missing work days and social events. Therefore, pain relief methods are essential to manage the symptoms. TENS therapy is one of the treatment methods that can help individuals control their pain. This article will provide an overview of TENS units, including how they work, their benefits, and safety considerations.
Overview of the TENS Unit in Australia
The demand for TENS units in Australia has been increasing due to their effectiveness in managing pain. These devices are small, portable, and easy to use, making them convenient for individuals to operate at home or on the go. TENS units typically come with electrodes that individuals attach to the skin near the pain area.
The device then delivers electrical currents through the electrodes, targeting the nerves and relieving pain. They are commonly used to treat a variety of conditions that may be acute or chronic. Historically, TENS machines were available in physical therapy and rehabilitation centres. However, technological advancements have made it possible to conduct therapy outside clinical settings.
The TENS units are available in two types: standard and wireless. A standard TENS machine comes with wires that connect the device to the electrodes, while a wireless TENS unit uses Bluetooth technology to transmit the electrical currents. Both types have adjustable settings for intensity and frequency, allowing users to customise their treatment based on their pain levels.
Types of Pain Treated by TENS
- Nerve pain: Also called neuralgia, this type of pain is caused by damage or dysfunction in the nervous system. It often feels like a burning, stabbing, or shooting sensation.
- Joint pain: It is a condition that causes aches or soreness in one or more joints. The risk factors are inflammation and infections.
- Muscle pain: It is a sign of injury, muscle overuse, infection, disease, or other health conditions like fibromyalgia. It can feel like a deep, steady ache or random sharp pains.
- Spinal pain: Conditions that affect the spine or thoracic regions. It is often due to poor posture and degenerative disc diseases.
How a TENS Unit in Australia Works
A TENS unit in Australia works by sending electrical impulses through the skin to the nerves. There are various mechanisms as to how it can alleviate pain. The first is stimulating the nerves to block or reduce the pain signals sent to the brain. It is attainable using high-frequency stimulation at 50-100 Hz.
Another mechanism is the release of endorphins, which are natural pain relievers. Endorphins also help reduce stress levels and promote a sense of well-being. In addition, they can improve blood circulation in the area, which helps reduce inflammation and accelerate healing. These effects are more effective using low-frequency electrical pulses at 2-10 Hz.
To use the TENS machine, it is crucial to identify the appropriate settings and electrode placement. Start by attaching the adhesive electrodes to the pain site and then turning on the device. Adjust the frequency and pulse duration to the desired setting. Also, begin at the lowest intensity level and gradually increase until the tingling sensations are comfortable.
Main Theories at Work
Two main theories explain how TENS work. The first is the Gate Control Theory. This theory suggests that mild electrical impulses stimulate the nerves in a way that “closes the gate” on pain signals travelling to the brain. By overwhelming the nervous system with the sensation, it can block the transmission of pain signals, providing relief.
The second theory is the Endorphin Release Theory. This theory proposes that the electrical impulses from the TENS unit trigger the release of endorphins in the body. They bind to opioid receptors and inhibit them from sending pain messages to the brain.
Benefits of Using a TENS Unit in Australia
There are several reasons why people use TENS units in Australia. One of the main benefits is its ability to provide drug-free relief. It can be a natural alternative to pain medications for those who have allergies or those who prefer to avoid their associated side effects. Additionally, TENS machines provide a non-invasive method of pain relief. It does not involve intrusive procedures, making them a safe and gentle treatment option.
Another benefit is its versatility in treating various pain conditions. Whether it is muscle soreness or neuropathic pain, a TENS unit is customisable to target specific areas of the body and provide targeted pain relief. This flexibility allows individuals to personalise their pain management approach and find the most effective treatment for their needs.
Furthermore, TENS machines are portable and easy to use. It enables people with chronic pain to incorporate their pain treatment into their daily routine. This accessibility allows individuals to take control of their pain management and improve their quality of life.
Is It Safe and Effective?
Using a TENS unit is generally safe and effective for many people. However, it requires operating the device as directed by the manufacturer and consulting with a healthcare professional before use. This is particularly crucial for those with certain medical conditions or implanted devices.
Moreover, following safety guidelines and not overusing the device is vital to prevent mild skin redness, irritation or other adverse effects. Also, be aware of sensitive areas to avoid, such as the eyes, head, and areas with reduced sensation. Lastly, do not use the device while sleeping, driving, or in water.
Conclusion
Many people use TENS units in Australia for good reasons. These portable devices offer a drug-free, non-invasive, and versatile option for pain relief. It utilises mild electrical pulses to stimulate nerves and trigger the release of endorphins. In addition, they are suitable for a wide variety of conditions, including chronic and acute pain. For effective treatment, it is advisable to understand the intensity and frequency settings of the device and their effects.
TENS machines are easy to use and allow individuals to control their pain management at their convenience. However, using them correctly is crucial to avoid any potential risks. Overall, TENS units can be a valuable tool in managing pain and improving the quality of life. Many types of devices are available in Australia, such as the wireless iTENS. Nevertheless, consulting a medical professional before use is vital for guidance and advice.
