Transcutaneous Electrical Nerve Stimulator TENS Machines: The Need to Know

A Transcutaneous Electrical Nerve Stimulator TENS machine is an electronic device that delivers electrical currents in the body. Accordingly, this electrical stimulation works in different mechanisms. It blocks the transmission of pain messages, triggers the release of endorphins, and improves blood flow. Nevertheless, the electrical device is easy to use. One needs to identify the treatment area and place the electrode pads. Then, turn on the device, adjust the settings, and activate the stimulation.

In a world where acute pain and chronic pain affects millions of people, finding a method of pain relief can be challenging. Pain management solutions, such as medications and physical therapy, may not always provide the desired relief. Hence, many individuals turn to TENS therapy to treat various types of pain. It is popular due to its non-invasiveness and drug-free form of pain relief. This article will present TENS machines, how it works, and how to use the device.

What is a Transcutaneous Electrical Nerve Stimulator TENS Machines?

The transcutaneous electrical nerve stimulator TENS machines are devices that provide a method of pain relief by sending electrical pulses to the body. This is done through the electrode patches placed on the skin. Accordingly, pain clinics, physical therapists, and medical professionals often use TENS as part of their treatment protocols. Also, individuals suffering from conditions may use TENS at home.

TENS devices come in both wired and wireless options. Wired TENS requires the use of lead cables to connect the electrodes to the central unit. Meanwhile, wireless TENS devices eliminate the need for wires. Hence, it promotes greater freedom of movement while undergoing TENS therapy. Users can control the electrical nerve stimulation manually or via smartphone through Bluetooth technology.

Both types of devices offer various features. Most TENS units have adjustable settings. This enables users to modify the frequency, intensity, and duration of electric current. Also, some models may extend pre-set programs. This directly targets a specific condition for convenience. Nevertheless, TENS devices can help manage different conditions and provide effective relief.

Treatable Conditions

  • Chronic pain: TENS therapy is often used to manage chronic conditions, such as arthritis pain, fibromyalgia, shoulder, neck, and backaches.
  • Acute pain: TENS devices are beneficial for addressing acute conditions like labour pain, postoperative pain, menstrual pain, and tension headaches.
  • Musculoskeletal pain: the unit can help treat joint pain, muscle spasms, and tendonitis. TENS machines can help relax muscles, reduce inflammation, and improve mobility.
  • Neuropathic pain: conditions involving nerve pain, such as sciatica, diabetic neuropathy, or nerve compression injuries, can be effectively managed with TENS.
  • Muscle tension: TENS units are frequently used in rehabilitation settings to manage and promote muscle recovery after injuries or surgeries.

How a Transcutaneous Electrical Nerve Stimulator TENS Machines Works

Transcutaneous electrical nerve stimulator TENS machines work by sending electrical currents to the body. This electrical stimulation triggers several physiological mechanisms. One key mechanism involves the stimulation of endorphin production. Endorphins are the natural painkillers of the body, and TENS therapy encourages the release of these neurotransmitters. This creates a sense of well-being and comfort.

Another way TENS operates is through the pain gate mechanism. This suggests that electrical pulses can override or close the neurological gates that allow pain signals to reach the brain. By flooding the nervous system with the non-painful sensation of electrical stimulation, TENS therapy effectively blocks the transmission of pain signals. Hence, it reduces the perception of discomfort.

Furthermore, TENS can also impact blood flow in the treatment area. The electrical stimulation can cause local blood vessels to dilate. Also, it delivers more oxygen and nutrients to body tissues. This improved circulation can help promote healing, reduce inflammation, and provide relief from pain and muscle tension. Overall, these physiological effects provide effective relief and manage a variety of conditions.

Benefits

TENS therapy provides a non-invasive approach. It does not involve surgery or the use of needles. Accordingly, TENS offer a drug-free alternative. This is particularly beneficial for individuals who prefer to avoid or minimise the use of medications. Also, TENS devices are portable. People can use it at home, work, or on the go. This enhances convenience and promotes consistent use.

Moreover, TENS provide customisable settings. This ensures that TENS therapy can be tailored to address different conditions. Additionally, TENS units offer a cost-effective long-term solution. It eliminates the need for ongoing medication refills or frequent visits to health professionals.

How to Use a Transcutaneous Electrical Nerve Stimulator TENS Machines

Using a transcutaneous electrical nerve stimulator TENS machine involves several key steps. Start by attaching the electrode pads to the central unit using lead cables. For wireless TENS, the user can connect it to a smartphone via Bluetooth. After that, locate the treatment area and prepare the skin before placing the electrodes. This promotes optimal conductivity for the electrical stimulation.

The next step is to position the electrodes on the skin. It is vital to adhere to the proper electrode placement for effective therapy. Typically, electrodes are placed around the perimeter of the painful area. Once the electrodes are in place, the user can turn on the settings. TENS devices may allow individuals to adjust the settings or choose a pre-set program for a specific condition.

Nevertheless, it is essential to start with the lowest settings and gradually increase them to a comfortable level. During the TENS therapy, the user should monitor their comfort level and any changes in pain perception. The duration of the treatment typically ranges from 15 to 30 minutes. Once the therapy is complete, turn off the device and gently remove the electrodes from the skin.

When to See a Doctor?

If the individual experiences an escalation of discomfort during or after TENS therapy, it is essential to consult a medical practitioner. This may indicate an underlying condition that requires medical assessment to address the source of the condition. Also, if the electrode placement site becomes red, itchy, or develops a rash, it is important to discontinue use and see a doctor.

Additionally, experiencing persistent or unusual sensations of numbness or tingling may indicate the need for medical evaluation. These symptoms may signify nerve compression, circulation issues, or other underlying concerns that necessitate examination by a healthcare professional.

Conclusion

In summary, transcutaneous electrical nerve stimulator TENS machines are a valuable tool for managing conditions. The devices are available in wired and wireless functionalities and offer various features. Accordingly, it works by sending electrical pulses to the body. This electrical stimulation can block pain signals, trigger the release of endorphins, and promote blood flow. Hence, these mechanisms can treat conditions like arthritis, postoperative pain, joint pain, tendonitis, diabetic neuropathy, and muscle pain.

Also, TENS units provide numerous benefits. It is non-invasive, drug-free, portable, customisable, and cost-effective. Furthermore, TENS devices are straightforward to use. The individual will identify the treatment area, place the electrodes, turn on the device, adjust the settings, and activate the stimulation. Nevertheless, it is essential to recognise the signs when to see a doctor. People may purchase a wireless and rechargeable TENS device from an online retailer, iTENS Australia.
