5 sensations of COld | 1.Intense cold 2.Burning 3.Aching 4.Analgesia 5.Numbness |
Effects of Cold | Vasoconstriction followed by vasodilation if cold is applied longer then 15-20 min(hemodynamic effect). Decrease in nerve conduction velocity starting 5 min of cooling (neuromuscular effect). Decrease Metabolic Rate |
What is the Hunting Response to application of Cold | repeated vasoconstriction + vasodilation after 15 min of cooling. |
4 Uses of Cryotherapy | 1.Inflammation Control 2.Edema Control 3.Pain Control 4.Modification of Spacticity 5.Symptom Management of MS 6.Facilitation 7.Cryokinetics 8.Cryostretch |
COntraindications to Cryotherapy | Cold Hypersensitivity, Cold intolerence, cryoglobulinemia, paroxysmal cold hemoglobinuria, raynaurds disease, over regenerating peripheral nerves, over an area with circulatory compromise or PVD |
Cold has greatest effect on which nerve type | greatest effect on conduction of small myelinated fibers, with least effect on unmylineated large fibers. |
