thermal agents Flashcards
thermal energy works by
transferring that from one object to another
cryotherapy
causes tissue temp to decrease
therm-therapy
produces a tissue temp to increase
electrical to mechanical energy
conversion
ice on leg is what type of mechanism
conduction
examples of conduction
ice massage
cold/ice packs
hot packs
cold spray
ice bath
types of convention
hot whirlpool
cold whirlpool
fluidotherapy
whole body cryotherapy
types of radiation
infrared lamps
laser
ultraviolet light
types of conversion
ultrasound
diathermy
why cold therapy?
- decrease temp
- decrease blood flow
- decrease metabolis
- decrees inflammation
- decrease muscle spasm
- decrease elasticity
why heat therapy?
- increase temp
- increase blood flow
- increase metabolism
- increase elasticity
- increase healing process
- decrease pain
cryotherapy: depth of the tissue temperature changes up to
5cm
cryotherapy: hemodynamic effects – when tissue temperature <50, a cold induced
vasodilation occurs
cryotherapy: physiologic response (4 stages)
cold
burning
achy
numbness
tissue temperature for therm-therapy
104 to 113
thermotherapy: depth of tissue temperature change
most superficial 1-3cm
- 2 heating agents deep up to 5cm
therm-therapy: hemodynamic effects initial heating causes
vasodilation
true or false: no heat during actor injury
true
therm-therapy - connective tissue effects:
- increased elasticity
- decreased viscosity
- decreases joint stiffness
- increases muscle flexibility
frostbite
freezing a body part and occurs when tissue temperature falls below 32F
burning greater than 113F could cause
tissue damage or burning or skin mottling can occur
hunting response
oscillation from vasoconstriction to vasodilation
