TENS Unit Machine: What are the Treatable Conditions?

A female newscaster reporting about TENS as a new faster pain relief

A Transcutaneous Electrical Nerve Stimulation or TENS unit machine is an electronic device that delivers electrical currents to the body. This electrical stimulation can modulate the way the body perceives pain signals. Also, the electrical impulses can stimulate the release of endorphins. With such basic science mechanisms, TENS can treat different types of pain or conditions, whether acute pain or chronic pain. Additionally, it can address neuropathic pain, musculoskeletal pain, and muscle discomfort.

Managing different types of pain is a common struggle for many individuals. Whether it is from injury or medical conditions, finding effective pain management techniques can be a challenge. Fortunately, advancements in technology have brought about the development of TENS devices. It is a safe treatment commonly used by pain clinics, health professionals, physical therapists, and individuals. This article will present how a TENS unit device works, the treatable conditions, and how to operate it.

How Does a TENS Unit Machine Work?

A TENS unit machine works by streaming low-voltage electrical pulses to the nerves through electrode pads placed on the skin. This operation involves several mechanisms of action. Foremost, when TENS devices deliver electric currents to the nerves, it can trigger the release of endorphins. Endorphins act as the natural painkillers of the body, which can create a sense of well-being.

Another way TENS therapy operates is by activating the Pain Gate Theory. According to this theory, the spinal cord contains a “gate” that can either allow or block pain signals from reaching the brain. When TENS units stream electric impulses, they can stimulate the sensory nerves that compete with pain messages. Hence, it can effectively close the “gate”, preventing the transmission of pain signals.

TENS treatment may also have an impact on blood circulation in the targeted area. The electrical stimulation from TENS can cause the blood vessels to dilate, increasing blood flow. As a result, it can enhance the delivery of oxygen and nutrients to the tissues. Nevertheless, this may contribute to the reduction of pain and the promotion of healing in the treatment region.

Benefits of TENS Therapy

  • Pain relief: it has the ability to provide relief from various types of pain or conditions.
  • Non-invasive and drug-free: it does not involve surgical procedures or the use of medications.
  • Customisable: many TENS devices feature adjustable pulse settings. This includes modifying the pulse rateintensity settings, and duration.
  • Portable: most TENS units are lightweight and compact. This allows individuals to incorporate TENS therapy into their daily routine.
  • Cost-effective: it eliminates the ongoing cost of medications or the frequent visits to healthcare providers.
  • Reduced side effects: this makes it a favourable option for people seeking relief with a lower risk of adverse reactions or complications.

Conditions a TENS Unit Machine Can Treat

The TENS unit machine can effectively treat a variety of conditions. Firstly, TENS therapy has been widely used to manage chronic pain conditions. This may include arthritis, shoulder pain, fibromyalgia, and backaches. Secondly, TENS treatment is beneficial in addressing acute pain conditions. This may result from labour pain, menstrual cramps, tension headaches, and sports injuries.

Thirdly, TENS devices can offer effective relief to neuropathic pain. It stems from the damage to the nerves. This may involve conditions such as sciatica, diabetic neuropathy, and post-herpetic neuralgia. Fourthly, TENS units are well-suited for addressing musculoskeletal pain. This affects the bones, muscles, and connective tissues. It may include conditions like joint pain, rheumatoid arthritis, and osteoarthritis pain.

Furthermore, TENS therapy can be beneficial for individuals experiencing localised muscle discomfort. This often results from overexertion, tension, or repetitive strain. The electrical stimulation from TENS can promote relaxation, which relieves muscular discomfort. Overall, TENS stands as a valuable tool for managing diverse sources of conditions.

Are There Potential Side Effects?

While the use of TENS is generally safe, there are still minimal potential side effects. In some cases, individuals may experience skin irritation at the electrode placement sites. Hence, proper skin preparation and regular checking of the skin are essential to reduce the likelihood of skin-related effects. Also, some may experience discomfort during the therapy due to the electrical pulses. Adjusting the settings can help address this discomfort.

In certain cases, the electrical impulses may cause involuntary muscle twitching. While this is not typically harmful, some people may find it uncomfortable. Modifying the settings can minimise the occurrence of muscle twitching and enhance overall comfort.

How to Operate a TENS Unit Machine

Operating a TENS unit machine involves several key steps. Begin by ensuring the device is powered off before starting the setup process. Then, check the unit to see if it is adequately charged or has fresh batteries. Next, attach the electrodes to the central unit using the lead cables. Alternatively, connect it to a smartphone via Bluetooth for wireless TENS devices.

Subsequently, identify the treatment area and prepare the skin. Place the electrode patches on the skin according to the specific placement recommendations provided in the user manual or by a health professional. Once the electrodes are in place, power on the TENS unit. This may include adjusting the settings (frequency, intensity, and duration) or choosing a pre-set program.

It is advisable to start the therapy with the lowest setting and moderately increase it to a comfortable intensity. Throughout the therapy session, it is essential to monitor the comfort level. Consequently, the treatment may last between 15 to 30 minutes. Once the therapy session is complete, power off the TENS unit and carefully remove the electrodes from the skin.

Safety Guidelines

Before using a TENS unit, it is essential to consult a healthcare professional. They can provide guidance on whether TENS therapy is appropriate for the specific condition. Accordingly, ensure that the electrode patches are placed on clean, dry, and healthy skin. Avoid positioning the pads on the head, eyes, mouth, throat, chest, bony regions, and broken skin.

Additionally, do not start the therapy session with a high setting. This can cause electrical shock and can lead to further discomfort. Moreover, if an individual experiences any unexpected side effects or discomfort, stop using TENS and consult a medical practitioner.

Conclusion

In conclusion, a TENS unit machine is a highly beneficial device for individuals seeking pain relief. It is an electrical device that works by delivering electrical currents to the body via electrodes placed on the skin. Consequently, this electrical stimulation operates in various mechanisms of action. It blocks the transmission of pain signals and triggers the release of endorphins. Hence, TENS can treat a variety of conditions. This may include fibromyalgia, tension headaches, diabetic neuropathy, rheumatoid arthritis, and muscle discomfort.

Moreover, TENS therapy provides benefits to users. It is non-invasive, drug-free, customisable, portable, cost-effective, provides pain relief, and has reduced side effects. Furthermore, operating the TENS unit involves several key steps. This includes preparing the device, locating the treatment area, placing the electrodes, adjusting the settings, and activating the electrical stimulation. Nevertheless, it is crucial to recognise the safety guidelines and the potential side effects of TENS therapy.
