Study Notes

Understanding Pain Physiology

Referred pain is perceived in an area other than the site of injury, often felt at a distance and generally referred to other structures in the same sensory dermatome.
Slow pain sensation is primarily transmitted by unmyelinated C fibers, which are poorly localized and have a dull or aching quality.
Anticonvulsants are helpful in treating neuropathic pain but are not used for acute pain management.
The physiologic mechanisms involved in the pain phenomenon are termed nociception, not sensitization, neurotransmission, or proprioception.
Conceptualizing pain physiology in four stages provides an opportunity for intervention in the pain experience, making it clinically useful.
Most sensory afferent pain fibers enter the spinal cord via the posterior nerve roots, not anterior, C fiber, or anterolateral roots.
Pain threshold is the level of painful stimulation required to be perceived and is similar from one individual to another.
Pain modulation is thought to be mediated by the release of endorphins, which are important modulators of pain perception.
Headache is one of the most common causes of acute pain, accounting for approximately 13 million visits each year in the United States.
