Transcutaneous electrical nerve stimulator TENS machines are portable tools that can relieve pain. It blocks pain signals from reaching the brain. In addition, this pain relief can trigger the release of endorphins, which are the natural painkillers of the body. To use a TENS machine, simply place the electrodes on the treatment area, turn on the unit, and adjust the settings. It is always advisable to consult a health professional before starting electrotherapy.
Chronic pain and acute pain are prevalent issues that affect many individuals regularly. However, finding an effective pain management solution can be a challenge. Traditional methods like pain control medications and exercise may not always be sufficient, leading people to explore alternatives. TENS is an alternative, non-invasive method that is drug-free. People can use it at home or on the go. This article will present TENS units, including their mechanism of action and proper usage.
What is a Transcutaneous Electrical Nerve Stimulator TENS Machine?
A transcutaneous electrical nerve stimulator TENS machine is a medical tool that uses low-voltage electrical currents to alleviate pain from various acute and chronic pain conditions. Doctors and physical therapists often use these in medical settings, like hospitals and pain clinics. However, people can also buy personal units. These small, battery-operated electronic devices are easy to carry around for effective pain relief.
People can buy TENS machines from online retailers and pharmacies without prescriptions. Several models from various brands are available, but generally, there are two types of TENS units. The wired or traditional unit utilises cables to connect the control unit and the electrode pads. Some products offer quad-channels, which enable users to link up to eight pads simultaneously.
Meanwhile, wireless units use Bluetooth to link the pads with the control unit. They usually offer advanced features like pre-set modes along with manually adjustable settings. These are ideal for individuals with active lifestyles since movements remain unrestricted during sessions. Hence, this enables them to do simple activities at home or during work.
Brief History of TENS Machines
- TENS treatment was first introduced in the 1960s.
- Electrical nerve stimulation was developed as an alternative to more intrusive pain management methods, such as medication or surgery.
- Originally, TENS was primarily utilised in the field of anesthesiology. It relieves pain during surgeries.
- Physiotherapists started to adopt TENS as a non-pharmacological pain management tool.
- In the 1970s, professionals used TENS to aid chronic and acute pain conditions.
- The TENS machine became more widely available to patients for home use in the 1980s.
- Today, practitioners apply the TENS technique in physiotherapy to manage a wide range of medical conditions.
How a Transcutaneous Electrical Nerve Stimulator TENS Machine Works
A transcutaneous electrical nerve stimulator TENS machine uses electrical impulses to stimulate the sensory nerves. It has adjustable settings that enable users to modify them depending on their comfort level and the condition they wish to treat. Some also offer preset modes, which enhance the convenience of TENS by reducing the need for experimentation.
Different settings can bring about various effects. High-frequency electric current (50-120 Hz) is ideal for immediate relief from sudden and severe pains. It triggers spinal nerve cells to block the transmission of pain signals to the brain. It also has a massage-like effect that can help relieve sore muscles and increase blood flow to the target area. Then, this aids in healing, improving recovery speed.
On the other hand, low-frequency electrical stimulation (2-10 Hz) works well for chronic pain conditions. Although temporary, its effects can last longer since it triggers the production of endorphins. They can improve moods and promote a sense of well-being. Furthermore, they can help reduce inflammation, increasing the range of motion.
Types of Pain TENS Can Relieve
A TENS device is a handy tool for relieving various types of pain. Health professionals often recommend TENS for different kinds of discomfort, including musculoskeletal pain, such as joint pain and postoperative pain. For those suffering from conditions like rheumatoid arthritis, TENS can offer relief by reducing inflammation and soothing sore joints.
Additionally, TENS is effective for neuropathic pain. It arises from damaged nerves. Moreover, it can alleviate phantom pain and stump pain experienced by amputees. Another common use of TENS is easing the intensity of labour pain. Even primary dysmenorrhea, or menstrual cramps, can be eased with the help of this electrical device.
How to Operate a Transcutaneous Electrical Nerve Stimulator TENS Machine
Using a transcutaneous electrical nerve stimulator TENS machine is a straightforward process. It is easy to self-administer due to its intuitive controls and does not require medical supervision. Nevertheless, taking safety precautions is ideal when using any electrotherapy device. Hence, preparing for the session by washing the target area and reading the instruction manual is recommended for effective pain relief therapy.
To start, the individual must apply the electrode pads on muscles near or on the source of discomfort. Then, they may turn the machine on and adjust the settings accordingly. However, it is best to start with low settings to avoid skin irritation, muscle twitching, or unsettling tingling sensations. Hence, they should gradually increase the intensity settings.
Users may set a timer to keep track of the session duration. TENS therapy usually lasts around 15 to 30 minutes, depending on the settings and the health issues they are addressing. Once the time elapses, the user should turn the machine unit off and remove the electrode patches.
Safety Guidelines
Although TENS therapy is safe for most people, taking safety precautions is necessary to prevent adverse events. Foremost, individuals should consult a medical professional before using any electrotherapy devices. They can diagnose the medical condition and ensure they do not have underlying conditions that disallow them from using TENS. These include pregnant women and those with heart disease, seizures, and epilepsy.
Furthermore, users must practice proper electrode placement. They should avoid sensitive areas like the spinal cord and broken skin. Individuals must also refrain from using TENS while driving, operating heavy machinery, or in water. Lastly, they must refrain from overusing the machine.
Conclusion
In conclusion, a transcutaneous electrical nerve stimulator TENS machine offers a portable and convenient solution for managing acute and chronic pain. By delivering low-voltage electrical currents to stimulate sensory nerves, it provides relief and promotes healing. Whether through wired or wireless models, users can adjust settings to suit their needs and preferences. With high-frequency currents for immediate pain relief and low-frequency stimulation for long-term benefits, TENS machines offer versatile pain management options.
Operating a TENS machine involves simple steps but requires caution to ensure safety and effectiveness. Users should read the manual, apply electrode pads correctly, and start with low-intensity settings to avoid discomfort. Consulting a medical professional is crucial, especially for individuals with certain medical conditions. Safety precautions must be observed. These include avoiding sensitive areas and not using TENS in specific situations. By following proper guidelines, individuals can experience relief from pain and discomfort without any adverse effects.
