PAM interventions partially control pain by activating non-nociceptive sensory nerves.

PAM interventions partially control pain by activating non-nociceptive sensory nerves.

• A. True
• B. False
• C. Only when used with medications
• D. They completely eliminate pain

Answer: (A)

Pain modulation with physical agent modalities works through gate control: stimulating large-diameter, non-nociceptive fibers (like Aβ fibers) activates inhibitory processes in the spinal cord that dampen the transmission of nociceptive signals to the brain. This reduces how strongly pain is perceived but does not completely remove it, so relief is partial rather than total. That’s why this statement is best: PAMs provide analgesia by engaging non-nociceptive nerves, and they can be effective on their own or as part of a multimodal pain-management plan. They do not require medications to work, and they don’t eliminate pain entirely.
