Document Summary
Pain receptors- nocioreceptors- responsive to different stimuli- carry it to spinal cord. 2 types of pain signals- a delta and c fibres. A delta: fast, large diameter, myelinated- important role because fast protection. C fibres- unmyelinated (slower), located on skin and deep tissue, tell us were sore after the fact. Our job with our modalities is to try and knock out the c fibres. 4 hz taps on ankle x 10 min. If a nerve is submitted to the passage of constant To conduct heat to or away from body. Blood flow drops below normal then you have vasoconstriction, vasodilation, vasoconstriction, vasodilation, then it is hypothalamus mediated and it levels out. Bottom of slide: bleakley et al (2006) 10 on -10 off -10 on is superior to 20 min on. Less pain in first week no change after that. Sites because they aren"t getting the oxygen they need. Moist heat goes deeper but dry heat is more tolerated.
