Cryotherapy

Question 0

Brief application of cold

Answer 0

Under :60 stimulating
Increase respiration, heart rate, no and muscle tone
Decrease muscle tone
Reduction of Edema and pain

Question 1

Main reactions to cold

Answer 1

Local vasoconstriction
Decreased circulation
Manage inflammation/congestion

Question 2

Prolonged cold

Answer 2

10+ minutes
Analgesia due to reduced conduction velocity
Decreased spasm activity (⬇️motor neuron impulses, ⬇️muscle spindle sensitivity)
Decreased elasticity and extensibility
Decreased respiration HR BP muscle tone

Question 3

Retrostasis

Answer 3

Fluid being mobilized from body surface toward deeper tissues and internal organs.

Question 4

Heat conserving mechanisms

Answer 4

Superficial vasoconstriction
Shivering
Decreased respiration

Question 5

Hunting response

Answer 5

Occurs when tissue temperature is reduced 12-15+ minutes OR brought below 10 degrees.

Cyclic periods of vasodilation and vasoconstriction

Derivation: drawing fluid away from main pathway toward chilled tissue
[active derivation: body expands E]

Only useful if person has relatively warm core temperature before being exposed to cold.

Question 6

Answer 6

SHARP

Swelling
Heat
Altered function
Redness
Pain

Question 7

Acute stage of inflammation

Answer 7

24-48 hours post injury
All cardinal signs present
Cold
Can lead to secondary hypoxia injuries resulting from swelling or accumulation of metabolic wastes

Question 8

Subacute stage of inflammation

Answer 8

72 hours to a few weeks
Regenerating stage
Contrast

Question 9

Chronic inflammation

Answer 9

Scar tissue and healing stage.

Heat therapy

Question 10

Hypoxia

Answer 10

Inadequate O2 supply to tissues

Question 11

Factors that influence cold’s effects

Answer 11

Temperature of application 
Temperature of individual
Duration of treatment
Size of treatment are
Adipose tissue
