Gate Control Theory
This theory suggests that non-painful input closes the “gates” to painful input, which prevents pain sensation from traveling to the central nervous system. TENS therapy is thought to activate these gates. For example, the electrical impulses from a TENS unit can override the pain signals from the inflamed plantar fascia, offering a period of relief. This allows individuals to perform stretches or exercises that might otherwise be too painful.
-
Endorphin Release
TENS therapy may stimulate the release of endorphins, the body’s natural pain relievers. Endorphins interact with opioid receptors in the brain, reducing pain perception. While the exact mechanisms are still being investigated, the potential for increased endorphin levels offers another pathway for pain management in plantar fasciitis. This can contribute to an overall improvement in comfort and function.
-
Modulation of Pain Signals
TENS can directly affect the transmission of pain signals along nerve fibers. The electrical pulses interfere with the signals, reducing their intensity before they reach the brain. This can lessen the perceived severity of plantar fasciitis pain. The adjustable settings on a TENS unit allow for personalized treatment, targeting specific pain levels and locations.
-
Reduced Muscle Tension
Tight muscles in the calf and foot can exacerbate plantar fasciitis pain. TENS therapy can help relax these muscles, alleviating tension and contributing to pain reduction.

Inflammation is a key component of this condition, contributing significantly to pain and dysfunction. Though TENS does not directly address the inflammatory process, its influence on other factors can create a more conducive environment for healing and inflammation reduction.
-
Improved Circulation
TENS therapy can promote vasodilation, increasing blood flow to the affected area. Enhanced circulation delivers more oxygen and nutrients, supporting tissue repair and potentially aiding in the removal of inflammatory mediators. For instance, increased blood flow can help flush out metabolic byproducts that contribute to inflammation in the plantar fascia. This improved circulatory response can play a supporting role in the overall healing process.
-
Muscle Relaxation
Tight muscles in the calf and foot can exacerbate plantar fasciitis symptoms and contribute to inflammation. TENS-induced muscle relaxation can alleviate this tension, indirectly reducing the mechanical stress that contributes to inflammatory processes. Relaxed muscles are less likely to compress surrounding tissues, including the plantar fascia, thereby reducing irritation and inflammation. This can create a more favorable environment for healing.
-
Pain Reduction and Movement
Reduced pain allows for increased movement and engagement in therapeutic exercises. Movement is essential for maintaining tissue health and promoting circulation, indirectly impacting inflammation. By enabling more movement, TENS therapy can indirectly support the natural healing processes that reduce inflammation in the plantar fascia. For example, gentle stretching facilitated by reduced pain can help improve tissue flexibility and reduce inflammation over time.
