Rebound Phenomenon
Rebound Phenomenon negates the ___________ effect of heat and cold
Therapeutic
__ to __ minutes maximum vasodilation heat produces
20 to 30 minutes
__ F / __ C temp of the skin when maximum vasoconstriction
60F / 15C
Continuation of heat application beyond 20-45 minutes may result in…
Tissue Congestion
Vasoconstriction
Risk of burn
Continuation of cold application below 15C results in…
Vasodilation
Protective and Prevents freezing of body tissues
Prolonged Cold application may result in
Impaired Circulation
Cell deprivation
Subsequent Tissue Damage due to lack of oxygen & Nourishment
Signs of tissue damage
Bluish Mottled skin
Numbness
Stiffness
Pallor
Conducts heat better than air
Moisture
Length of time the body is exposed and the size of the skin area affects…
Body tolerate treatment
Smaller Area = Better tolerance
Physiologic responses to heat
Increase blood flow
Increase supply of oxygen
Decrease Blood viscosity
Increase tissue metabolism
Physiologic responses to cold
Decrease Blood circulation
Decrease capillary permeability
Delayed re absorption of fluid
Increase Coagulation of blood
Responds to signals from the thermal receptors
