During long-term TENS use, sensory receptors may accommodate to the continuous current. Which modulation strategy prevents this accommodation?

Explanation:
Receptors adapt to a continuous electrical stimulus, so the sensation and the pain-relieving effect can fade with long-term TENS use. Switching to burst-mode modulation introduces brief on/off periods, giving receptors time to reset and preserving the intermittent input needed to sustain gate-control analgesia. This intermittent stimulation prevents sensory accommodation better than simply increasing current, stopping use, or changing electrode size, which don’t address the adaptation mechanism.
