CRYOTHERAPY

Question 1

CRYOTHERAPY is…

Answer 1

therapeutic application of a substance to the body which results in withdrawal of heat from the body

Question 2

What is Conduction?

Answer 2

the transfer of energy through direct contact

Question 3

How does Conduction work?

Answer 3

the colder surface extracts heat from the warmer surface

Question 4

The magnitude of the temperature changes depends on

Answer 4

1. Temperature difference
2. Time exposed
3. type of cooling exposed
4. thermal conductivity of the area cooled

Question 5

Cold causes … which decreases blood to the cooled area by increasing smooth muscle contraction

Answer 5

Vasoconstriction

Question 6

2 Hemodynamic Effects of Cold

Answer 6

1. Decreased local metabolites in the blood - edema is kept to minimum
2. decreased blood flow

Question 7

Pain is received (via cryotherapy) by

Answer 7

decreased or blocked sensory nerve conduction

Question 8

Other Effects of COLD

Answer 8

decreased inflammation
decrease ROM by decreasing collagen extensibility
decrease muscle spasm and spasticity (decreased nerve conduction velocity)
Connective Tissue will become stiffer

Question 9

20-30+ minutes of cold leads to a …. ?

Answer 9

Hunting Response

Question 10

The Hunting Response is …. ?

Answer 10

Cold induced vasodilation where you get cyclic warming (heat) and increased metabolism of cooled areas to maintain homeostasis

Question 11

Purpose of the Hunting Mechanism

Answer 11

a mechanism THOUGHT to prevent cold induced tissue damage

Question 12

The Superficial tissue response to cold

Answer 12

first skin temp decreases then subcutaneous adipose THEN intra-articular region THEN core-temp drops

Question 13

STAGE 1 of Perceived Cryotherapy

Answer 13

intense cold within 3 minutes of application

Question 14

STAGE 2 of Perceived Cryotherapy

Answer 14

burning/aching from 4-7 minutes

Question 15

STAGE 3 of Perceived Cryotherapy

Answer 15

8-15 analgesia and local anesthesia

Question 16

STAGE 4 of Perceived Cryotherapy

Answer 16

15-20/30 minutes- Numbness

Question 17

Tissue Destruction occurs at

Answer 17

55 F

Question 18

3 Types of Cryotherapy

Answer 18

Cold Packs, Ice Massage, Vapocoolant Spray, Ice bath & Whirlpool

Question 19

With Vapocoolant you … (It causes… Evaporation)

Answer 19

Spray and Stretch

Question 20

9 Indications for Application of Cryotherapy

Answer 20

1. Muscle Tone and Spasticity
2. Quick cold can facilitate muscle contraction
3. Early acute injury, bleeding & edema
4. Emergency care for acute thermal burns
5. increased pain threshold
6. decrease edema
7. decrease joint inflammation
8. Decreased synovial inflammation (RA)
9. Decreased collagenolysis (RA)

Question 21

CONTRAINDICATION for Cold

Answer 21

1. Developed cold sensitivity - nerve impairments, cryoglobulinemia, Raynaud’s phenomena,
2. Not over impaired Circulation
3. Cardiac or respiratory involvement
4. regenerating peripheral nerves
