2 HEAT AND COLD Flashcards
THERAPEUTIC HEAT: HOW IS HEAT CREATED? (3)
Chemical sources, metabolism.
Electrical sources.
Frictional sources.
CONDUCTION
Heat is transmitted through the touch of a heating agent.
Ex: hot packs.
CONVECTION
Movement of air or fluids.
Ex: fluidotherapy.
CONVERSION
Changing one state to another to create heat.
ex: ultrasound.
RADIATION
Heat that comes from a light source.
ex: infrared light.
EVAPORATION
Sweating.
3 RESPONSES TO HEAT
- Increased metabolism.
- Increased blood flow.
- Stimulation of nerve endings in skin and tissues.
WHAT SHOULD THE CLIENT FEEL WITH HEAT
A feeling of warmth in area.
A feeling of relaxation.
INDICATIONS FOR THERAPEUTIC HEAT
Relaxation.
Promotes soft tissue extensibility.
Decrease muscle spasm.
PRECAUTIONS TO THERAPEUTIC HEAT
Edema.
Poor circulation.
Sensory deficits.
Very young and very old.
Skin or lymphatic cancer.
Metal implants.
Pacemakers.
Pregnancy.
Menstrual cycle.
CONTRAINDICATIONS TO HEAT
Deep vein thrombophlebitis. (DVT)
Acute inflammation/hemorrhage.
Malignant tumor.
Existing fever.
DVT
Deep Vein Thrombosis: blood flow in one of the deep veins of your body is blocked by a blood clot.
TYPES OF HEATING MODALITIES
Hot packs.
Wax.
Infrared radiation.
Warm whirlpool.
Fluidotherapy.
Short wave diathermy.
Ultrasound.
SENSATION TESTING
Soft touch test.
10 times.
HOW MANY LAYERS UNDER A HEAT PACK?
6-8 Layers.
CRYOTHERAPY
Therapeutic cold.
HOW DOES THE BODY LOSE HEAT
Conduction.
Convection.
Radiation.
Evaporation.
WHAT SHOULD THE CLIENT FEEL WITH COLD
A feeling of cold/discomfort in the area.
Stinging.
Burning/aching.
Numbness.
Being tense then relaxed.
Experiencing less pain (analgesia) and possibly less muscle spasm.
BODYS RESPONSE TO COLD
Decrease in tissue temperature.
Decrease in local metabolism.
Decrease followed by an increase in local blood flow.
INDICATIONS FOR COLD
Reduce pain.
Reduce spasticity/spasm.
Reduce muscle spasm.
Reduce swelling.
Promote repair.
Provide excitatory stimulus when muscles have low tone.
PRECAUTIONS TO COLD
Psychological considerations.
Poor circulation.
Cardiac conditions.
Altered sensation.
Cold sensitivity.
Very young or very old.
Mental status.
Peripheral vascular disease.
Open wound.
