Conventional TENS is characterized by what pulse frequency?

• A. Low (2-4 pps)
• B. High (30-150 pps)
• C. Moderate (60-80 pps)
• D. Variable (5-20 pps)

Answer: (B)

Conventional TENS relies on high-frequency stimulation to rapidly engage large-diameter sensory fibers and modulate pain signals at the spinal cord level, producing quick, comfortable analgesia with minimal or no muscle contraction. The pulse frequency is high, typically 30 to 150 pulses per second (pps), with common clinical use around 50–100 Hz. This high-frequency delivery creates immediate sensory relief by the gate control mechanism, distinguishing it from modes that use lower frequencies to achieve longer-lasting, opioid-mediated analgesia.
