Cryotherapy is used just as heat is, in the rehabilitation of injuries. Cryotherapy is often used for pain relief, fever reduction, control bleeding, prevention or reduction of edema from trauma and inflammation, decrease in muscle spasm, and reduction of spasticity. Cold is usually applied during the first 24 to 48 hours following an injury. Applying cold first usually results in decreased fluid filtration into the tissue interstitium, decreased inflammation and pain, and a decrease in metabolic rate.
Effects Of Cold Therapy
The decrease in the temperature of Skin/Soft Tissue leads to:
Decrease in the blood flow
Vasoconstriction (narrowing of blood vessels) afterward followed by Vasodilatation
It prevents it against Hypoxic (absence of enough oxygen) damage. Cold therapy basically decreases the amount of blood flow delivered to an area
Helps in reducing muscle spasm.
Decreases metabolic rate by limiting the oxygen flow to cells.
Reduces inflammation by decreasing blood flow due to contraction in blood vessels.
