Endorphinic TENS: What It Is, Benefits, and Applications

iTENS small wing kit with written features

Transcutaneous Electrical Nerve Stimulation (TENS) is a natural method of pain relief that utilises an electrical device. The battery-operated unit emits mild electric currents to stimulate the sensory nerves. Endorphinic TENS can provide several benefits, including being non-invasive, drug-free, customisable settings, and portability. This treatment method is applicable for both acute and chronic pain conditions. Nevertheless, it is essential to consult a health professional before starting electrotherapy.

Dealing with pain due to health issues can be challenging to handle. Fortunately, different forms of pain relief are available. However, the effects of each one may vary from person to person. Thus, people should understand the components behind the treatment methods to make informed decisions. For instance, they should learn about the TENS unit before administering it. This article will provide more information about TENS endorphinic therapy, including its benefits and applications.

What is an Endorphinic TENS?

An endorphinic TENS machine is an electrotherapy device for analgesic purposes. Endorphinic refers to the release or activation of endorphins. The device works by sending low-voltage electric currents through electrodes placed on the skin. In addition, it has adjustable settings to give different pulsating effects for various types of pain. This ability allows users to use the device with the appropriate amount of stimulation for their pain level.

These machines are typical in physical therapy and pain centres to assist patients dealing with chronic pain or injuries. By providing targeted electrical stimulation, they help people manage their conditions and improve their ability to engage in daily activities with less discomfort.

TENS endorphinic devices come in two types: wired and wireless. Wired devices require a connection cable between the machine and the electrodes. Meanwhile, wireless models operate without such constraints. It uses Bluetooth technology so users can access a mobile app for further convenience and freedom of movement. Nevertheless, both types offer the same pain-relieving effects.

How It Works

  • Inhibition of pain signal: A TENS endorphinic machine may use high frequency (50-120 Hz) to activate the pain gate mechanisms. This approach stimulates certain nerve fibres in the spinal cord to close the pathways of pain signals, hindering them from reaching the brain.
  • Endorphin release: Low-frequency stimulation (2-10 Hz) induces the release of endorphins. These are hormones that act as natural painkillers and mood enhancers.
  • Improve blood circulation: it facilitates the healing process and provides the necessary resources for motor recovery, aiding in tissue regeneration and restoration of normal physiological conditions.
  • Muscle relaxation: TENS pain therapy helps reduce inflammation, alleviating muscle tension and soreness.

Benefits of Endorphinic TENS

Endorphinic TENS offers several benefits. Firstly, it is non-invasive, meaning it does not require any surgery or needles. Instead, small electrodes are placed on the skin to deliver gentle electrical impulses. This makes it a comfortable option for those seeking pain relief without penetrating procedures.

Secondly, it is drug-free, making it a safer alternative for people who may have allergies or sensitivities to certain drugs. Thirdly, this electrostimulator for pain offers customisable treatment options. Users can adjust the intensity and frequency of the electrical pulses to suit their specific needs. This customisation allows targeted pain relief, tailoring the electrotherapy session to address individual pain thresholds and preferences.

Fourthly, the TENS endorphinic device is portable, allowing users to carry the device and use it whenever needed. This portability enhances its convenience, enabling people to manage symptoms of pain on the go, whether at work, at home or during physical exercises. Lastly, it can be used as an adjunctive treatment alongside other pain management techniques.

Is It Safe and Effective?

TENS therapy is a safe and effective treatment method for pain relief. However, there are guidelines to follow to prevent adverse effects from electrical stimulation. Firstly, people should consult a health professional to ensure compatibility with TENS medical products. People with cardiac rhythm devices should avoid electrotherapy since it may cause their machines to malfunction.

Secondly, practice proper electrode placement. Do not apply pads to sensitive areas, such as the spinal cord, open wounds, skin rashes, throat, and head. Thirdly, do not overuse the machine. The entire session typically lasts between 15 to 30 minutes. Start with low settings to prevent electric shocks and discomfort.

Applications of Endorphinic TENS

An endorphinic TENS machine can effectively manage a variety of conditions. For instance, chronic pain. This is a pain condition that lasts for more than three months. Some examples are knee osteoarthritis pain, backaches, and carpal tunnel syndrome. Also, a TENS device can support the healing of acute pain, which typically fades within three months but may develop into chronic pain. These include labour pain, period cramps, postoperative pain, and sports injuries.

Additionally, the electrical nerve stimulation unit can treat musculoskeletal pain, a condition that affects the muscles, bones, ligaments, tendons, and nerves. TENS helps relieve knee joint pain, shoulder aches, and cervical pain, all of which are musculoskeletal conditions. People can even use multiple electrode patches in one session to target different areas of pain simultaneously.

Furthermore, TENS can help with neuropathic pain. Damage or dysfunction in the nervous system can cause this type of pain. Individuals with diabetic neuropathy, sciatica, and phantom limb pain can rely on electrical stimulation for pain relief. However, users should consult a healthcare provider beforehand because TENS does not suit everyone.

Signs to See a Doctor

People should consult a health professional if they experience severe or worsening pain despite using a TENS device. It may also include new or unexplained symptoms. This may indicate an underlying health issue that requires medical attention. In these cases, a doctor can determine the cause of the pain and explore other treatment options.

Additionally, it is necessary to seek medical care if there are allergic reactions that persist after using a TENS therapy unit. Allergic reactions may include skin rashes, itching, or swelling at the electrode placement site. A healthcare professional can assess the situation and provide appropriate guidance.


In conclusion, the endorphinic TENS machine emerges as a versatile and effective tool for managing pain. Its non-invasive nature, coupled with its drug-free approach, offers a safer alternative for people seeking relief from chronic pain or injuries. With customisable treatment options and portability, users can tailor their pain management regimen to suit their specific needs. Whether used independently or in conjunction with other therapies, TENS stands as a valuable asset in improving the quality of life.

TENS machine offers effective relief for various types of pain, including chronic, acute, musculoskeletal, and neuropathic pain. It can help manage conditions like knee osteoarthritis, backaches, labour pain, and diabetic neuropathy. However, users must consult a healthcare provider to ensure compatibility. If experiencing severe or worsening pain or allergic reactions, it is essential to seek medical attention promptly. Overall, when used correctly, TENS therapy is a safe and beneficial option for pain relief.
