What is the primary purpose of TENS as an adjunctive therapy?

• A. Reduce the amount of pain meds needed
• B. Cure underlying condition
• C. Replace all analgesics
• D. Cause muscle stimulation in legs only

Answer: (A)

TENS provides nonpharmacologic analgesia that is used alongside other therapies, with the main aim of reducing the amount of pain medication a patient needs. The electrical stimulation delivered through skin electrodes modulates pain signals, typically by activating larger nerve fibers that can inhibit transmission of pain at the spinal cord level (gate control theory) and, with certain settings, can also trigger the release of endorphins. This adjunct approach helps lower reliance on systemic analgesics, which can reduce side effects and improve participation in rehabilitation. It does not cure the underlying condition or replace all analgesics, and it isn’t limited to a single muscle group—electrodes can be placed at various sites to address different pain locations. In short, its primary purpose is to lessen reliance on pain meds as part of a broader pain management plan.
