What is the function of TENS therapy?

TENS therapy, which stands for Transcutaneous Electrical Nerve Stimulation, primarily functions by stimulating nerves to provide pain relief. This is achieved through the application of low-voltage electrical currents via electrodes placed on the skin. The stimulation helps to mask pain perception by altering the way pain signals are transmitted to the brain, essentially blocking some of the signals that communicate pain.

Additionally, TENS can promote the release of endorphins, the body's natural painkillers, further contributing to pain control. It's commonly used in various settings, including physical therapy and pain management, helping individuals manage chronic pain, post-surgical discomfort, and acute injuries.

In contrast to the other options, TENS therapy does not primarily aim to cool down inflamed tissues, develop muscle strength, or promote healing in broken bones, which are associated with different therapeutic modalities.
