Video Summary

This video discusses the definitions and classifications of pain. The revised definition of pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. It covers various types of pain such as paresthesias, dysesthesia, hyperesthesia, hyperalgesia, hyperpathia, aloadenia, phantom sensation, and phantom pain. Pain is classified as acute, subacute, or chronic based on the duration. It can also be classified as nociceptive, neuropathic, or idiopathic based on the underlying cause. The video explains the mechanisms involved in pain perception, including transduction, transmission, modulation, and perception. It also discusses the gate control theory and how input from low threshold fibers can inhibit nociceptive input.
