What is a TENS Machine: Definition and Features

A man holding his nape and lower back Individuals looking for alternative pain management solutions may ask what is a TENS machine. It is a small, portable device that helps relieve various pain conditions. It works by sending electrical impulses through the skin using electrode pads. Transcutaneous Electrical Nerve Stimulation (TENS) machines come in different types, either wired or wireless, and have adjustable pulse rates and intensity levels. They also often have pre-set modes for different types of pain.

The use of TENS machines or electrotherapy dates back as far as 2500 B.C. Ancient Greek medical practitioners discovered that certain fish or eels emitting electrical impulses could provide pain relief. It was not until the late 19th century that electrotherapy devices gained mainstream recognition. Since then, TENS therapy has become more popular. This article will provide information on what a TENS machine is, including its features and proper usage.

What is a TENS Machine?

People may wonder what is a TENS machine. It is a portable, battery-operated electronic device that provides pain relief. It uses a set of electrode pads to deliver electrical impulses through the skin. This non-invasive device targets the sensory nerves and induces them to block pain signals through the pain gate mechanism. Particularly, high-frequency TENS (50-120 Hz) causes the spinal nerves to close, preventing the pain signals from reaching the brain.

Another way a TENS machine relieves pain is through endorphin release. The machine utilises low-frequency electrical stimulation (10 Hz or below) to produce endorphins or natural painkillers. Endorphins help suppress the nerve cells from sending pain messages and reduce stress and anxiety. They have similar effects as oral analgesics but without the risks of dependence or harmful side effects.

Moreover, the TENS device can help boost circulation. The constant stream of electrical pulses stimulates the motor nerves and muscles. This increases blood flow and oxygen in the area, which can help reduce inflammation and cramping sensations. It is advisable to consult with a medical professional before using TENS.

Treatable Conditions

  • Acute pain: a sudden and intense pain that typically lasts for a short period of time. This includes postoperative pain, fractures, broken bones, labour pain, muscle sprain, and period pain.
  • Chronic pain: it refers to ongoing pain that persists for more than three months, even after the initial injury or illness has healed. These include conditions such as cancer pain, fibromyalgia, ankle tendonitis, osteoarthritis, frozen shoulder and bursitis.
  • Body aches: it can be a general feeling of soreness or localised pain in specific areas. This includes wrists, elbows, shoulders, knees, ankles, hips, thighs, hands, or feet.

What is a TENS Machine – Features

Aside from knowing what is a TENS machine, people have to consider its features. TENS devices have different features that are suitable for various types of pain in adults. Firstly, the device type. This refers to the traditional (wired) and wireless TENS units. Traditional TENS connect the remote control to the adhesive pads via wires. On the other hand, wireless machines integrate Bluetooth technology.

Secondly, the settings or programs. This includes adjustable pulse rates and intensity levels. A customisable setting allows each person to tailor the treatment to their comfort level. Meanwhile, the pre-set modes are programs with pre-determined settings. It provides users with convenient pain management by selecting an automatic option.

Thirdly, it is advisable to consider the size, portability, and ease of use. These preferences depend on the pain condition or lifestyle. For example, people with active lifestyles may opt for a wireless TENS machine to carry them easily or use them discreetly. Moreover, the controls should be easy to operate. Lastly, users may choose either rechargeable or non-rechargeable batteries.

Benefits of the Electrotherapy

Electrotherapy, specifically through the use of a TENS machine, offers numerous benefits as a drug-free method of pain relief. It serves as an effective alternative to traditional pain medications, providing a non-addictive solution without lasting side effects. Additionally, the non-invasive nature of TENS is an advantage because the electrical device removes the need for needles or surgery.

Moreover, a TENS machine grants individuals greater control over their pain relief. The adjustable settings allow for personalised treatment plans tailored to specific needs. Lastly, TENS provides targeted pain relief. Users can strategically place the electrode pads on the affected areas, directly stimulating sensory nerves.

What is a TENS Machine – How to Use

People can apply TENS therapy in a few simple steps after understanding what is a TENS machine and its features. To begin, they should clean and dry the area of the skin where they will apply the electrode patches. It is crucial to ensure that the skin is free from any lotions, oils, or creams. These substances may interfere with the effectiveness of the treatment.

After preparing the skin, the person should carefully place the TENS electrodes on the treatment area. Additionally, they need to make sure to space the pads evenly to ensure uniform distribution of electric current. Moreover, the user can adjust the intensity and frequency based on their comfort level. Physical therapists recommend starting with a low setting and increasing gradually if needed.

Once the session is over, individuals have to remove the electrodes slowly, peeling them off the skin gently. Furthermore, it is best to clean the pads after each use and store them properly. By following these steps, people can effectively manage their acute or chronic conditions.

Safety Guidelines

Safety is a vital aspect of learning how to use a TENS machine. Firstly, consult a medical professional to determine if TENS is a suitable treatment for a particular medical condition. These professionals can also advise the correct electrode placement and settings to use. Secondly, do not place the TENS pads on open wounds or broken skin.

Thirdly, it is crucial to avoid sensitive areas like the head, eyes, throat, spine, and near varicose veins. The electric nerve stimulation in these locations may worsen the condition or cause complications. Furthermore, prolonged use may cause overstimulation. For continuous treatment, allow a 20-minute break between sessions.

Conclusion

What is a TENS machine is a common question for people looking for alternative methods of pain relief. It is a portable device that runs on batteries and alleviates pain by sending electrical impulses through electrode pads. These impulses block pain signals and trigger the release of endorphins. Whether wired or wireless, with customisable settings or pre-set modes, TENS machines provide user-friendly pain management. Considerations like size, controls, and battery preference enhance the overall experience.

Using a TENS device involves simple steps. One must clean and dry the skin, apply electrodes evenly, and adjust settings for comfort. Afterwards, removing the electrodes gently and proper pad maintenance ensures effective management of conditions. More importantly, users should follow some safety guidelines. Consulting a medical professional, avoiding open wounds, and steering clear of sensitive areas is crucial. Furthermore, a 20-minute break between sessions prevents overstimulation. Following these guidelines empowers individuals to harness the benefits of TENS therapy.
