Electrical Stimulation TENS Unit: The Need to Know

electrical stimulation tens unit

Transcutaneous Electrical Nerve Stimulation (TENS) uses an electrical device to deliver electrical current to the body as a method of pain relief. The electrical stimulation TENS unit works by blocking pain signals and stimulating the release of endorphins. When using TENS, it is essential to follow proper guidelines. Foremost, inspect and prepare the electronic device. Then, locate the treatment area and place the electrode pads. Lastly, turn on the device, adjust the settings, and activate the stimulation.

Throughout history, individuals have sought various forms of pain relief. Traditional pain management methods include medications, physical therapy, and heat therapy. However, they may not always provide the desired relief. Hence, this led to the development and popularity of TENS devices. It emerges as an effective treatment option for various types of pain. This article will present the electric stimulation TENS unit, including how it works and the usage guidelines.

What is an Electrical Stimulation TENS Unit?

An electrical stimulation TENS unit is a portable device that sends electrical pulses to the body to manage medical conditions. The delivery of electric currents to the body is possible through the electrode patches placed on the skin. Accordingly, pain clinics, healthcare providers, and physical therapists often incorporate TENS into their treatment plans for patients. Individuals may also use TENS as part of their home-based pain management strategies.

The stimulation for pain relief devices comes in two main types: wired and wireless. Wired TENS uses lead cables to connect the electrodes to the central unit. Wireless TENS, on the other hand, utilises wireless technology, eliminating the need for physical wires. Nevertheless, individuals can control the machine manually or via smartphone or tablet.

Both devices offer numerous features to enhance the treatment. Most TENS units allow users to adjust the intensity, pulse width, and pulse rate. Also, TENS machines may include guidelines to assist users in correctly placing the electrode patches on the skin. Moreover, some devices offer pre-programmed modes designed for specific types of pain.

Treatable Conditions

  • Acute pain: often sudden and sharp. It can result from labour painpostoperative painprimary dysmenorrhoea, and tension headaches.
  • Chronic pain conditions: persists over a long period of time. This can be caused by conditions such as arthritis pain, fibromyalgia, and backaches.
  • Musculoskeletal pain: it affects the bones, tendons, muscles, ligaments, and nerves. It can result from overexertion, poor posture, or conditions like osteoarthritis.
  • Neuropathic pain: caused by the damage of nerves. Conditions like diabetic neuropathy and sciatica can lead to nerve discomfort.
  • Achy muscles: this can result from sore musclesmuscle strain, or spasms. TENS can aid in the management of muscle-related discomfort.

How an Electrical Stimulation TENS Unit Works

When a person experiences pain, nerve fibres carry pain messages from the site of discomfort to the spinal cord and then to the brain. Accordingly, the electrical stimulation TENS unit works by closing the “gate” in the spinal cord. Hence, it effectively blocks the transmission of pain signals to the brain. This operation is known as the pain gate mechanism.

TENS devices can also stimulate the release of endorphins. Endorphins are the natural pain-relieving chemicals of the body. When the TENS unit delivers electrical pulses, it can trigger the production and release of endorphins. This mechanism can help reduce the level of pain intensity and promote a sense of well-being.

Furthermore, TENS can influence the blood circulation in the treatment region. The electrical currents cause blood vessels to dilate. As a result, it can help in delivering oxygen and nutrients to the body tissues. This also removes waste products, thereby aiding in the healing process. Overall, these mechanisms contribute to providing pain relief and improving the quality of life.

Benefits of TENS Therapy

Firstly, TENS therapy can provide effective relief for various conditions. Secondly, it is known for its non-pharmacological and non-invasive approach. This makes it an attractive option for people who prefer to avoid reliance on medications or invasive procedures. Thirdly, TENS treatment is highly customisable. People can modify the settings to suit specific needs.

Fourthly, TENS units are portable and easy to use. This allows individuals to incorporate TENS into their daily routines. Additionally, TENS therapy offers a potential alternative or complement to other pain management strategies. Moreover, TENS is safe with minimal risks of adverse effects.

Usage Guideline When Using an Electrical Stimulation TENS Unit

Before using an electrical stimulation TENS unit, it is essential for individuals to consult a health professional. This is particularly important for people with underlying health issues. Once clear, prepare the TENS device by connecting the electrodes to the central unit using lead cables. For wireless devices, connect it to a smartphone or tablet via Bluetooth technology.

After that, locate the treatment area and clean the skin to remove oil or dirt. Then, place the electrodes on or around the area of pain. It is vital to follow the proper electrode placement for optimal results. Once the electrodes are in place, turn on the TENS unit. Users can adjust the settings, and some models may allow individuals to choose a pre-set program.

Start the TENS therapy with the lowest setting and gradually increase it to a comfortable level. During the treatment, feeling a tingling or buzzing sensation is normal. However, it is crucial to monitor the skin to ensure that there is no irritation or discomfort. The duration of the therapy may last 15 to 30 minutes. Once complete, turn off the device and remove the electrodes from the skin.

When to See a Doctor?

If the user experiences persistent redness, swelling, or irritation at the electrode placement site, it is essential to consult a health professional. This may indicate an allergic reaction or an issue with the electrode placement. Also, if the pain does not improve or worsen with TENS unit use, it is vital to see a doctor. Professionals can help determine the most effective treatment approach.

Additionally, if the individual experiences unexpected side effects, such as dizziness or nausea, it is crucial to seek medical attention. These symptoms may indicate an adverse reaction to the electrical stimulation and require evaluation.

Conclusion

In summary, an electrical stimulation TENS unit is a beneficial and effective tool for pain management. This is a wired or wireless device with various features that deliver electrical pulses to the body. It is commonly used by health professionals, therapists, and individuals. Accordingly, it works based on the Pain Gate Theory, the release of endorphins, and improving blood circulation. These mechanisms are helpful in managing chronic pain, acute pain, neuropathic pain, and musculoskeletal pain.

Furthermore, TENS provides numerous benefits. It can treat various conditions, it is drug-free, non-invasive, customisable, portable, and can complement other treatment strategies. Moreover, knowing the usage guidelines is important. Begin by preparing the device. Then, locate the treatment area, place the pads, and adjust the settings. However, knowing the signs when to see a doctor is crucial. TENS devices are available in numerous stores, including the online retailer iTENS Australia.
