TENS Medical Equipment: What It Is, How It Works, and How to Use

A female reporter showing news about TENS as a new faster pain relief

A Transcutaneous Electrical Nerve Stimulation or TENS medical equipment is an electronic device that sends electrical impulses to the body as a method of pain relief. Consequently, these stimulating pulses work in various mechanisms. It blocks the transmission of pain signals to the brain and prompts the release of endorphins. Furthermore, using the medical device is easy. Start by preparing the device. Then, identify the treatment area and place the pads. Finally, turn on the unit and adjust the settings.

Living with a constant pain condition can significantly impact daily activities, productivity, and overall well-being. Fortunately, advancements in medical technology have introduced innovative products to manage different types of pain effectively. An effective TENS device is one such breakthrough that has gained significant popularity. This article will present the TENS unit medical equipment, including how it works and how to use the machine.

What is TENS Medical Equipment?

One advancement in the healthcare setting is the use of TENS medical equipment. It is a small, battery-operated device that delivers electrical pulses to the body via adhesive electrodes placed on the skin. Consequently, healthcare professionals, pain clinics, and pain specialists often use TENS as part of their treatment plans for their patients. Additionally, the medical equipment can be utilised by individuals at home.

TENS devices come in various forms to cater to different needs. There are small, portable TENS machines that can be discreetly worn. This enables people to use it whenever needed. Meanwhile, there are larger TENS units, typically seen in clinics or healthcare facilities. Nevertheless, people can control the management of pain manually or on a smartphone via Bluetooth.

Furthermore, TENS therapy can treat various types of pain. They are commonly used for managing chronic conditions. This may include knee pain, neck pain, arthritis, fibromyalgia, and neuropathy. Moreover, TENS can be beneficial for acute conditions. This typically results from menstrual cramps, tension headaches, postoperative discomfort, and injuries.

Features of the Device

  • Adjustable pulse settings: it allows users to modify the pulse rateintensity levels, and duration.
  • Pre-set program modes: some advanced TENS models have pre-programmed settings to directly target a specific condition.
  • Portable design: it is compact, lightweight, and can be easily carried around.
  • Multiple electrode pads: TENS units come with multiple electrodes that can be placed on different parts of the body.
  • Rechargeable battery: many TENS devices come with a rechargeable battery. This eliminates the need for frequent battery replacements and ensures continuous usability.
  • Easy operation: the straightforward controls and clear instructions make it suitable for people with varying levels of technical expertise.

How TENS Medical Equipment Works

The TENS medical equipment operates on the basis of several physiological mechanisms. When the TENS device delivers electrical impulses, it stimulates nerve fibres, prompting the release of endorphins. Endorphins are the natural chemicals in the body that act as neurotransmitters, binding to opioid receptors. Nevertheless, it functions as a natural painkiller, promoting a sense of well-being.

TENS therapy also works in accordance with the Gate Control Theory of Pain. According to this theory, the sensation of pain is regulated by a “gate” in the spinal cord. This can open or close to allow or block pain signals from reaching the brain. By stimulating the nerve fibres through TENS therapy, it can essentially close the “gate”, inhibiting the transmission of pain signs and alleviating discomfort.

In addition, TENS treatment can modulate blood circulation in the treatment region. This potentially promotes the delivery of oxygen and nutrients to the tissues. Hence, it may contribute to reducing discomfort and supporting tissue healing. Moreover, the electric pulses from the TENS device can stream in low frequencies (below 10 Hz) and high frequencies (above 50 Hz).

Benefits

TENS therapy allows for the precise targeting of specific areas of the body experiencing discomfort. This provides localised relief without affecting the entire body. Accordingly, TENS equipment is versatile. It can manage various types of conditions. Furthermore, TENS treatment is non-invasive and drug-free. It does not involve any injections, surgical procedures, or the intake of oral medications.

Moreover, TENS equipment allows for the customisation of treatment parameters. This enables people to tailor the therapy to specific needs and preferences. TENS therapy is also cost-effective. It eliminates the cost of certain pharmaceutical treatments or surgical procedures.

How to Use a TENS Medical Equipment

To use the TENS medical equipment, begin by ensuring that the device is properly charged or has fresh batteries. Then, connect the electrodes to the central machine using lead cables or to a smartphone via Bluetooth for wireless. Next, identify the treatment location and prepare the skin by cleaning and drying it. After that, position the self-adhesive electrodes, adhering to the proper pad placement.

Once the electrode pads are in place, turn on the TENS unit. Most TENS devices allow individuals to adjust the settings (frequency, intensity, and duration). Also, some models may enable people to choose a pre-set program. Thus, select a program for a specific condition. Medical practitioners recommend starting with the lowest settings and moderately increasing them to a comfortable level.

Accordingly, once the TENS device is set up, the user can initiate the electrical stimulation. The advisable duration of TENS therapy is 15 to 30 minutes. Hence, have breaks for longer treatment sessions. When the therapy session is complete, turn off the TENS unit and carefully remove the electrodes from the skin. Clean the skin to remove any gel residue from the electrode pads.

Safety Precautions

Before using TENS equipment, it is crucial to consult with a healthcare professional. They can assess whether TENS therapy is suitable for the specific condition. Additionally, individuals with specific medical conditions, such as pacemakers, heart conditions, epilepsy, or pregnancy, should not use TENS without consulting a medical practitioner.

When placing the electrodes, do not position the pads on certain areas, including the head, eyes, mouth, throat, chest, bony regions, and broken skin. During the therapy, pay attention to any sensations experienced and take action as necessary. Avoid using TENS equipment while sleeping, bathing, driving, or operating machinery.

Conclusion

In summary, TENS medical equipment is a battery-powered device that sends electrical currents to the body via electrodes placed on the skin. The device comes in various forms: small (usually wireless) and large (usually wired). It includes features such as adjustable settings, pre-set programs, portable design, and easy operation. Nevertheless, health professionals, therapists, and individuals often use TENS to treat different types of conditions. TENS therapy can manage conditions, whether chronic or acute discomforts.

Furthermore, TENS works based on the principle of the pain gate mechanism and the release of endorphins. Also, it extends benefits. It is versatile, non-invasive, drug-free, customisable, cost-effective, and provides targeted relief. Moreover, using the TENS device is easy. One must begin by preparing the unit. Then, locate the treatment area and place the electrodes. Lastly, turn on the device and adjust the settings. However, it is crucial to know the safety precautions for optimal relief.
