In brief-intense TENS, what electrode placement technique is MOST commonly used?

• A. Stimulation point placement
• B. Dermatomal placement
• C. Bipolar placement
• D. Proximity to the injury site

Answer: (A)

Electrode placement strategy for brief-intense TENS aims to maximize rapid activation of the pain-modulating pathways. The best approach is stimulation point placement—putting pads over acupuncture points or motor points—because these sites respond more readily to electrical current. Targeting stimulation points lets the high-intensity, short-duration pulses recruit large-diameter A-beta fibers quickly, which helps gate the pain signals and can trigger endogenous opioid mechanisms for fast relief. Dermatomal placement follows a spinal segment but doesn’t guarantee optimal fiber recruitment for immediate analgesia. Bipolar placement refers to how two electrodes are arranged rather than where they’re placed for analgesic effect. Proximity to the injury site can work in some cases but is not as reliable as stimulation-point placement for achieving the rapid relief characteristic of brief-intense TENS.
