What does TENS stand for?

The correct answer is "Transcutaneous electrical nerve stimulator." TENS therapy involves the use of low-voltage electrical currents for pain relief, and the name accurately describes the method of delivering those electrical impulses through the skin (transcutaneous) to help manage pain.

This technique is commonly used in physical therapy, pain management, and rehabilitation settings. The electrical impulses work by stimulating the sensory nerves, which can alter the perception of pain and may also promote the release of endorphins, the body's natural painkillers.

The other options do not provide the correct terminology related to this therapy. For instance, while they reference nerve stimulation, they inaccurately describe the method or use terminology that does not align with established medical convention. Understanding the definition and application of TENS is crucial for recognizing its role in pain management and patient care.
