Cryotherapy & Thermotherapy Flashcards
Define inflammation
Complex physiological response to vascularized tissues to stressors including pathogens, chemical irritants,
and tissues damage
Inflammation is _______ to cause, tissue type, or location
Nonspecific
Immune response system is _____
Specific
When does inflammatory response start
Immediately after injury and last several days
What are S&S
Redness Swelling Pain Increased temp LOF
What is the goal of inflammatory response
Limit blood loss and remove debris
Define Vasodilation
Increase blood flow to area to bring WBC (heat&redness)
Define increased capillary membrane permeability
Allows WBCs to leak through walls into intracellular space and plasma protein to leak out (swelling)
Define phagocytosis
WBCs remove damaged tissue (neutrophils arrive first and are chemotactic)
How long does formation of a clot take?
12-48 hrs
What are the three types of tissue
Labile cells
Stabile cells
Permanent cells
What are Labile cells
Have EXCELLENT regenerative capacity(skin, bone marrow, respiratory etc.)
What are stabile cells
Have LESS regenerative ability (liver, kidneys, pancreas, etc.)
What are Permanent Cells
Have NO regenerative ability( caradic cells, CNS nerves, eye nerves, etc.)
What is Fibroplasia
Scar formation
What stage is fibroblastic repair
Development of new tissue (fibroblasts form type 3 collagen)
What stage is the maturation-remodeling
Type 3 collagen is replaced with type 1 which makes the fibers stronger
How long does the maturation-remodeling stage take?
From a couple months to years
What are the three stages of healing
Inflammatory response
Fibroblastic Repair
Maturation-Remodeling
What is Wolff’s Law
Tissue and bone remodel along lines of greatest stresses
If inflammation is necessary why do we control it
Prevent it from becoming more swollen
Is there a why to totally stop inflammation?
Yes by using corticosteroids
Why do we want to stop inflammation
to prevent further damage
Define cryotherapy
The application of cold for therapeutic purposes to decrease both superficial and deep tissues temps
Define thermotherapy
The application of heat for therapeutic purposes to increase superficial tissues temp
What are the 4 ways of energy transfer
Convection
Conversion
Radiation
Conduction
What is conduction
Transfer of heat through DIRECT CONTACT between a hotter and cooler areas ex: ice and heat pack
What are corticosteroids
It blocks tissue from swelling used for c-spine injury
What is keloids
Abnormal scar tissue
What is convection
Transfer of heat by MOVEMENT OF AIR OR LIQUID between regions of unequal temp
Ex: whirlpool/fluidotherapy
What is radiation
Radiation is the exchange of heat energy produced by ELECTROMAGNETIC waves
Results in largest amount of heat transfer
What is conversion
Energy change from one form to another
Does not apply to superficial cold or heat
Ex: Ultrasound
