thermal Flashcards
benefits of warm thermal modalities
increase vasodilation
increased metabolic rate
relaxation of muscle spasm
pain relief
increase elastic of muscle tissue
benefit of cold thermal modalities
vaso contriction and decreased blood flow
decreased metabolic rate
pain relief
reduce edema
reduce spaticity
what kind of heat transfer is ultra sound
conversion
non thermal energy is converted to heat
what are some examlpes of patients that might need hot and cold testing
spinal cord injury
peri neuropathy
stroke
what is vasodilation
increased blood flow > soft tissue healing
how does heat effect pain
increase thermoreceptor activity which has a counter irritant effect
contra for heat
Do not use over areas of impaired sensation,
area of malignancy,
hemorrhagic areas,
acute inflammation,
confused patients,
abdomen of pregnant women,
USE adequate layers
paraffin bath used mostly for what population
RA
paraffin contra
same as heat pack
check the skin
contra to cold therapy
anesthetic skin,
cold sensitivity,
Raynaud’s,
open wounds, or
areas of decreased circulation
what are the types of ultra sound
MIST
conventional
low intensity pulse
MIST
debribment of wounds
open wounds
conventional
used for soft tissue pathology
soft tissue, wounds
low intensity pulse
bone healing
bone fracture
ultra sound penetration - 1MHZ and 3MHz
1 MHz - deeper (low freq)
3 MHZ - superficial (high freq)
