thermotherapy Flashcards
(31 cards)
how thermotherapy works:
heat dilates blood vessels, increases circulation, increases blood flow (hyperemia)
local superficial heating is indicated for ______ conditions.
subacute
produces lower temperature at the site of the pathology relative to the higher temperatures in the superficial tissues, which results in analgesia
local superficial heating
____ ______ effect is desired in later stages of healing
deeper heating
diathermy and ultrasound are ____ heating
deep
HP, paraffin, fluidotherapy, whirlpool are all ____ heating
local superficial
physiological effects of heat application:
increased (5)
- cardiac output
- metabolic rate
- pulse rate
- respiratory rate
- vasodilation
physiological effects of heat application:
decreased (5)
- blood pressure
- mm
- blood to internal organ
- blood flow to resting mm
- stroke volume
reasons why we should use therapeutic agent
indications
- pain
- DOMS
- sprains
- strains
- articular problems
- mm pain and spasms
- Jt stiffness
- decreased ROM
- myofascial TP
- mm guarding
are all ______ for thermotherapy
indications
goals for thermotherapy:
- to produce relaxation
- to increase ROM/flexibility
- reduce pain
- accelerate healing
- preparation for other interventions
precautions(9):
- cardiac insufficiency
- edema
- impaired circulation
- impaired thermal regulation (MS)
- metal in tx site (US/diathermy)
- topic creams/lotions
- demyelinated nerves (MS, TOS, CTS)
- open wounds
- pregnancy
CONTRAindications (9):
- acute or early subacute traumatic and inflammatory conditions
- decreased sensation
- Deep vein thrombosis DVT
- Peripheral Vascular Disease PVD
- impaired cognitive function (precautionish)
decreased circulation (precautionish) - malignant tumors
- tendency towards hemorrhage or edema
- very old/very young patients (precautionish)
heat transfer from warmer object to cooler object by means of direct molecular interaction from physical contact
conduction
heat transfer by movement of air or fluid from a warmer area to a cooler area by moving past cooler area
convection
transfer of heat from a warmer object to a cooler object by means of electromagnetic energy without the heating of a medium
radiation
Tx Guidelines
- must be performed by qualified PT, PTA, SPTA
- Position patient comfortably, expose drape appropriately, remove jewelry
- inspect and assess tissue and sensation
- call bell or alert instructions given to patients
- check patient frequently
- dry and inspect skin at conclusion of tx
- document specific procedure used
The 10 questions to ask:
- When did your injury occur?
- Did you have any bruising or bleeding?

- Do you have normal feeling in this area?
- Do you have a history of cancer?
- Are you pregnant or trying to get pregnant?
- Do you have any heart or circulation problems?
- Do you have any metal in this area?
- Have you applied creams to this area today?
- Do you have any nerve issues (CTS, MS)?
