For TENS, which description matches its typical use?

• A. Pain for smaller areas
• B. Pain for larger areas
• C. Muscle strengthening
• D. Wound healing

Answer: (A)

TENS is used primarily for pain relief by stimulating cutaneous nerves at the skin surface, and it is most effective when applied to a localized, smaller area near the painful site. This modality works by altering pain signal processing—often through the gate control mechanism and, with certain settings, endogenous opioid release—so the patient feels reduced pain in the targeted region. Because the goal is analgesia for a specific location, the typical use is not about covering large areas. It’s also not intended for muscle strengthening (that role belongs to electrical muscle stimulation) or for wound healing (which uses different electrical approaches).
