Which statement best describes the role of TENS in pain management?

• A. Cures the underlying tissue damage.
• B. Helps manage pain without addressing the underlying cause.
• C. Reduces inflammation through mechanical means.
• D. Destroys nerve tissue.

Answer: (B)

TENS provides temporary relief by altering how pain signals are perceived, not by healing the tissue that’s causing the pain. It delivers electrical stimulation through the skin to nerves, which can dampen pain transmission at the spinal cord level (consistent with gate control) and, with certain settings, may trigger the body’s own pain-relieving chemicals. Because of this mechanism, TENS reduces pain while the underlying tissue problem remains untouched, making it a tool for symptom management rather than a cure. It doesn’t mechanically reduce inflammation, nor does it destroy nerve tissue. In practice, it’s used as an adjunct to rehabilitation to improve comfort and participation, while addressing the root tissue issue through other therapies.
