What is the goal of transcutaneous electrical nerve stimulation (TENS)?

Transcutaneous electrical nerve stimulation (TENS) is primarily aimed at providing pain relief. This is achieved by delivering low-voltage electrical currents through the skin to stimulate the underlying nerves. The mechanism behind this involves the activation of the body's natural pain control systems, potentially leading to the release of endorphins and blocking the transmission of pain signals to the brain.

While the other options, such as muscle enhancement, improved circulation, and joint stability, may have their own therapeutic modalities, they are not the main focus of TENS. Muscle enhancement typically involves different types of electrical stimulation specifically designed for strengthening muscles. Improved circulation often requires methods like compression therapy or more active physical interventions that engage circulation directly. Joint stability is usually addressed through specific exercises and rehabilitation techniques designed to strengthen the muscles and ligaments around a joint. Thus, the primary goal of TENS remains firmly rooted in the management and relief of pain.
