Gate Control Theory
TENS is thought to operate based on the Gate Control Theory of pain. This theory posits that non-painful input closes the “gates” to painful input, preventing pain signals from reaching the brain. TENS, by delivering low-voltage electrical pulses, effectively floods the nervous system with non-painful signals, potentially reducing the sensation of pain from the inflamed plantar fascia. This can translate to a decrease in perceived pain intensity and an increased ability to engage in activities previously limited by discomfort.
-
Endorphin Release
Electrical stimulation from TENS can trigger the release of endorphins, the body’s natural painkillers. These endogenous opioids bind to opioid receptors in the brain, reducing pain perception and producing an analgesic effect. This natural pain relief mechanism complements the Gate Control Theory, providing a two-pronged approach to pain management in plantar fasciitis. Increased endorphin levels can contribute to an overall sense of well-being and potentially reduce reliance on pharmaceutical pain relievers.
