test 2.2 Flashcards
what are examples of deep thermotherapy
ultrasound & shortwave diathermy
–Depth of heating effects = greater than 2 cm
what are examples of superficial thermotherapy
l: heat packs, paraffin
–Transfer of heat occurs through conduction
–Depth of heating effects = capable of increase skin temperature (less than 2 cm)
true or false
heat can be used 48-72 after an injury
false
how long does it to heat the tissue 1-2 cm
15-30 mins
what is the optimal temperature of thermotherapy
104-113F
what is the max WWP for the following: wrist/hand, foot/ankle, elbow, knee, thigh
Wrist/hand-112 foot/ankle-110 elbow-108 knee-106 thigh-104
true or false
First 5-6 minutes: body absorbs heat faster than it can dissipate it
true
true or false
After 7-9 minutes: temperature gradients begin to even out & slightly decline
true
when does rebound vasoconstriction occur
20 min into the treatment
true or false
Modalities such as hot packs encounter rebound vasocontriction
false
what does endorphin release when encountered with heat
relaxing effect
what is the primary limiting factor for the effective depth of heat penetration
