Cryo/thermotherapy Flashcards
used to produce a local heating or cooling of superficial tissue
conductive thermal energy modalities
direct contact, continues until equal temps reached. Heat can be transferred to or from patient
conduction
direct contact of a circulating medium. Transfers more heat than conduction
convection
various forms of energy into the body where they convert to heat. Mechanical, electrical, or electromagnetic. US, diathermy
conversion
emission of thermal energy from excited energy. Does not need medium to transport. Infrared.
radiation
Material must absorb energy first. Energy released when changing from liquid to gas
evaporation
conduction modalities
- ice/cold/hot pack
- cryocuff
- paraffin
- cold spray
convection modalities
- hot/cold whirlpool
- fluidotherapy
radiation modalities
- infrared
- laser
- ultraviolet
conversion modalities
- US
- Diathermy
With convection, the faster the medium circulates…
the faster heat can transfer
Greatest physiologic effects of cooling modalities
analgesic effect
_____ contraction strength can be improved with application of ice
eccentric
heating/cooling has minimal to no effects on
- proprioception
- joint position sense
- balance
______ has a prolonged effect on reducing pain
cryotherapy
local temp is low for about 30 min, intermittent periods of vasodilation occur for 4-6 min, then return to vasoconstriction for 15-30 min to warm up superficial tissue
Hunting response/ hunter’s reflex
thermotherapy effects
- increased metabolism
- vasodilation/increased vascular pressure
- increased blood flow
decreases mm spindle sensitivity to stretch
thermotherapy
thermotherapy modalities
- warm whirlpool
- hydrocollator packs (moist hot packs)
- paraffin
- fluidotherapy
- infrared
Paraffin uses ________ to deliver heat
conduction
Methods of paraffin application
- dip and wrap
- immersion
- paint
Instructions prior to paraffin use
- remove jewelry
- inspect area
- wash and dry
Dip and wrap parameters
- 6-10 redips
- wrapped for 10-15 min
dip immersion parameters
- dip and wait to dry
- redip for up to 20min
paint method parameters
- 6-10 layers
- 20 min cool down
paraffin contraindications
- open lesions
- rashes
- skin infection
- new skin/scar
