In brief-intense TENS, the intensity is typically:

In brief-intense TENS, the intensity is typically:

• A. Higher than sensory-mode TENS to provoke stronger responses.
• B. Lower than sensory-mode TENS to avoid sensation.
• C. About the same as sensory-mode TENS.
• D. Not related to patient sensation.

Answer: (A)

Brief-intense TENS delivers a strong, short-duration stimulus that reaches beyond a comfortable tingling to engage deeper nerve fibers and trigger analgesic mechanisms. To achieve this effect, the intensity is set higher than sensory-mode TENS, so the patient experiences a stronger paresthesia (and sometimes a brief muscle response) but remains within tolerance. This higher intensity is what allows the deeper fiber input needed for the rapid pain relief sought with this mode, unlike sensory-mode TENS which uses a lower, comfortable intensity. If the intensity were lower, it wouldn’t recruit the deeper pathways; if it were about the same, there would be no distinct analgesic advantage; and if it weren’t related to patient sensation, it would ignore the crucial factor of patient tolerance and feedback.
