What is Plantar Fasciitis?

Plantar fasciitis is a common foot condition characterized by inflammation of the plantar fascia, a thick band of tissue that runs along the bottom of the foot, connecting the heel bone (calcaneus) to the toes. The plantar fascia acts like a shock absorber and supports the foot’s arch during weight-bearing activities such as walking, running, or standing.

When the plantar fascia becomes irritated or overstretched, it can lead to microtears and inflammation, resulting in pain and discomfort. Plantar fasciitis typically causes sharp or stabbing pain in the heel, especially when taking the first steps in the morning or after prolonged rest periods. The pain may also worsen with activity and improve with rest.

What is TENS?

TENS, an acronym for Transcutaneous Electrical Nerve Stimulation, is a non-invasive and drug-free pain management technique that utilizes low-voltage electrical currents to alleviate acute and chronic pain.

The method involves using a compact, battery-operated TENS unit that delivers controlled electrical impulses through electrodes placed on the skin near the painful area. 

These electrical signals are thought to interfere with transmitting pain signals to the brain, providing temporary pain relief and promoting the release of endorphins, the body’s natural painkillers.

The TENS unit is programmable, allowing users to adjust the intensity and frequency of the electrical stimulation to suit their specific needs. The application of TENS is widespread in the medical field, frequently used in physiotherapy, sports medicine, and pain clinics. It can benefit conditions such as arthritis, back pain, musculoskeletal injuries, and neuropathic pain. 

TENS is generally well tolerated, but its effectiveness may vary from person to person and across different types of pain. It is essential for individuals interested in using TENS to consult with a healthcare professional to ensure proper electrode placement and to determine the most suitable settings for their condition.

While TENS is generally considered safe, certain precautions, such as avoiding using electrodes near the eyes, on broken or irritated skin, or in areas with reduced sensation, should be observed. 

Pregnant women and individuals with pacemakers or other electronic implants should also avoid using TENS without prior medical advice. Overall, TENS offers a non-invasive and potentially effective means of pain management for those seeking alternative approaches to pain relief without relying on medications or invasive procedures.

How does the TENS machine Work for Plantar Fasciitis?

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive pain management technique that uses a small battery-operated device to deliver electrical impulses to the nerves through the skin. While TENS does not directly treat the underlying cause of conditions like Plantar Fasciitis, it can help manage its pain and discomfort. Here’s how the TENS machine works for Plantar Fasciitis:

Nerve Stimulation

The TENS machine has electrode pads placed on the skin around the area of pain, in this case, the foot affected by Plantar Fasciitis. When turned on, the device emits mild electrical impulses that travel through the skin and stimulate the nerves in the area.

Gate Control Theory

One theory behind how TENS works is the “gate control theory” of pain. According to this theory, the electrical stimulation from the TENS machine interferes with transmitting pain signals to the brain. The electrical impulses activate non-painful nerve fibers, which essentially “close the gate” to transmitting pain signals, reducing pain perception.

Endorphin Release

Another proposed mechanism is that TENS may stimulate the release of endorphins, the body’s natural pain-relieving chemicals. Endorphins can help block pain signals and promote a sense of well-being.

Increased Blood Flow

TENS may also promote increased blood flow to the affected area, which can aid in delivering oxygen and nutrients to the tissues and facilitate the healing process.

What are The Benefits of a TENS machine for Plantar Fasciitis?

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive pain relief therapy using a low-voltage electrical current to stimulate nerve fibers through the skin. It can be beneficial for managing pain associated with various conditions, including plantar fasciitis. Here are some potential benefits of using TENS for plantar fasciitis:

  1. Pain Relief: TENS can help alleviate pain by blocking pain signals from reaching the brain. The electrical impulses stimulate the nerves, releasing endorphins, the body’s natural painkillers, which can relieve pain.
  2. Non-Invasive: TENS is a non-invasive treatment, meaning it does not involve surgery or the use of medications. It is considered a safe and low-risk option for managing pain.
  3. Reduced Need for Medications: By effectively managing pain, TENS may reduce the need for pain-relieving medications, potentially avoiding their side effects and interactions.
  4. Increased Circulation: The electrical stimulation from TENS may improve blood circulation in the affected area, promoting healing and reducing inflammation.
  5. Muscle Relaxation: TENS can help relax tense muscles around the plantar fascia, reducing muscle spasms and enhancing flexibility in the foot.
  6. Home Use: TENS devices are often portable and easy to use, which allows patients to use them at home, providing convenient and continuous pain management.
  7. Adjunct to Other Treatments: TENS can complement other therapies for treating plantar fasciitis, such as stretching exercises, physical therapy, and orthotics.

Where do you put the TENS for plantar fasciitis?

When using TENS for plantar fasciitis, the electrodes should be placed strategically to target the affected area and surrounding nerves. Here are some general guidelines, but please remember that these are not a substitute for professional medical advice:

Electrode Placement

Place the electrodes on the skin of the affected foot, targeting the area where you feel the most pain or discomfort. Common placement sites include:

  • Around the heel: Place one electrode on the bottom of the heel and another on the back.
  • Across the arch: Place one electrode on the ball of the foot and the other on the opposite end of the arch.
  • Across the sole: Place one electrode on the ball of the foot and the other on the heel.

Electrode Positioning

Make sure the electrodes are secure and adhere well to the skin. They should be positioned parallel to the direction of the plantar fascia to provide the best stimulation.

Intensity and Settings

Start with low intensity and gradually increase it to a comfortable level. Follow the instructions provided with your TENS device and consult with a healthcare professional for guidance on the appropriate settings.


The duration of each TENS session can vary, but it is generally recommended to use TENS for about 20-30 minutes per session, multiple times a day if needed.

Final Words

In conclusion, using a TENS (Transcutaneous Electrical Nerve Stimulation) machine for plantar fasciitis shows promising potential as a non-invasive and drug-free method to alleviate pain and discomfort associated with this common foot condition. The electrical impulses delivered through the TENS machine are believed to stimulate nerves and promote the release of endorphins, providing temporary relief to individuals suffering from plantar fasciitis. While further research and clinical trials are needed to establish its long-term efficacy, the TENS machine offers a convenient and accessible option for managing plantar fasciitis symptoms, complementing traditional treatments and enhancing overall patient well-being. It is essential for individuals seeking to use TENS therapy for plantar fasciitis to consult with healthcare professionals to ensure proper usage and suitability for their specific condition.
