Document Summary
Biopsychosocial models: gate-control theory: sensations that signal pain are modified, neural gate regulates pain experience. Brain can regulate pain signals and modify them. Signals also come from other places (e. g. peripheral fibers carrying info about other types of touch) Desending pathways from brain to this gate. Gate open: there is amplication from peripheral fibers and brain along with the signals from pain fibers. Gate less open: e. g. rubbing a sprained ankle to dull the pain and subjective experiences from the brain that reduce pain signal transmitted. Beliefs: catastrophizing, fear avoidance, perceived control, self-efficacy. Help chronic patients understand that pain is not a signal of harm or threat. Catastrophizing imagining the worst possible outcome have worse function. Those with chronic pain have a fear of incurring more pain start avoiding doing things. Those who have perceived control are more functional. Need to find ways to function in spite of pain and understand that pain is not going to go away.
