Osteoarthritis

Question 13

When is the contrast bath used and why?

Answer 13

In the subacute phase. Used to transition from cold to nmodalities.

Question 14

Is the contrast bath good for swelling?

Answer 14

No

Question 15

What kind of analgesic effects can the contrast bath have?

Answer 15

Sharp sensory change tends to cause a decrease in pain and break the pain spasm cycle.

Question 16

When should you end your treatment with cold modalities?

Answer 16

When you want vasoconstriction.

Question 17

When should you end your treatment with warm modalities?

Answer 17

When you want vasodilation

Question 18

What is cryokinetics?

Answer 18

Combination of cold and exercise

Question 19

What does CIVD stand for

Answer 19

Cold induced vasodilation

Question 20

What is CIVD?

Answer 20

AKA Huntington response. Increase in tissue temp during cold therapy

Question 21

What are the goals of cryotherapy?

Answer 21

Decrease/relieve pain
Decrease blood flow/metabolism
Protect injured tissue
Decrease muscle spasm

Question 22

T/F

You should freeze and reuse a chemical ice pack?

Answer 22

Never

Question 23

What are the advantages of cold whirlpool

Answer 23

can envelope entire joint. Can perform active exercises while cooling tissue. Whirlpool prevents thermopane (warm layer around foot), but causing turbulence in the water.

What are the disadvantages of whirlpool

Answer 24

Part cannot be elevated. Not ideal for acute situation.

Question 25

Is ice massage good for an acute injury?

Trigger points. Cutaneous numbing of pain. Does not cause temperature change below the epidermis.
Decreased ROM
Muscle spasm

Question 29

What are the indications for cooling and rewarming therapy?

Answer 29

Acute injury
Pain (decrease nerve conduction velocity)
Spasm
Chronic and inflammatory arthritis
