heat therapy & cryotherapy

Question 1

heat therapy modalities (6)

Answer 1

warm whirlpool
infared heat w/ solux lamp
hotmud
warmhydrocollator packs
paraffin baths
fluidotherapy

Question 2

what is Warm whirlpool

Answer 2

postsurgical modality to increase systemic blood flow and mobilization of the affected body part.

Question 3

Infrared heat with a Solux lamp

Answer 3

biggest advantage of an infrared lamp is that superficial tissue temperature can be increased, even though the unit does not touch the patient. The infrared energies have a depth of penetration of less than 1 cm, thus the physiologic effects are primarily superficial and directly affect the cutaneous blood vessels and nerve receptors.

Question 4

Paraffin baths

Answer 4

It is a simple and efficient, although somewhat messy, technique for applying a fairly high degree of localized heat. Paraffin treatments provide six times the amount of heat available in water because the mineral oil in the paraffin lowers the melting point of the paraffin. The combination of paraffin and mineral enhances the patient’s ability to tolerate heat from paraffin better than from water of the same temperature.

Question 5

Fluidotherapy

Answer 5

It is a dry heat modality that uses a suspended air stream, which has the properties of a liquid. Its therapeutic effectiveness in rehabilitation and healing is based on its ability to simultaneously apply heat, massage, sensory stimulation for desensitization, levitation, and pressure oscillations.

Question 6

uses of heat therapy

Answer 6

1. reduction of pain and inflammation in subacute conditions
2. improves blood flow thus improving tissue injury
3. increases local metabolic rate which in turn produces more heat improving blood flow and supply of oxygen, wbc and nutrients
4. relaxation and decreases guarding of skeletal muscles so can be used in strains and sprains and muscle spasms

Question 7

Contraindications

Answer 7

⦁	Acute musculoskeletal conditions.
⦁	Impaired circulation.
⦁	Peripheral vascular disease.
⦁	Skin anesthesia.
⦁	Open wounds or skin conditions.

Question 8

what is cryotherapy

Answer 8

tissue temperature decrease for a variety of therapeutic purposes

Question 9

cryotherapy modalities (8)

Answer 9

⦁	Cold spray
⦁	Cold hydrocollator packs
⦁	Cold or ice whirlpool
⦁	Ice packs
⦁	Ice massage.
⦁	Ice immersion
⦁	Contrast baths
⦁	Cryo-cuff
⦁	Cryokinetics

Question 10

indication for the use of Cold hydrocollator packs

Answer 10

indicated in any acute injury to a musculoskeletal structur

Question 11

indication for the use of Ice packs

Answer 11

indicated in acute stages of injury, as well as for prevention of additional swelling after exercise of the injured part.

Question 12

indication for the use of Cold or ice whirlpool

Answer 12

indicated in acute and subacute conditions in which exercise of the injured part during a cold treatment is desired.

Question 13

Cold spray

Answer 13

such as Fluori-Methane, do not provide adequate deep penetration,
provide adjunctive therapy for acupressure techniques to reduce muscle spasm.

Question 14

Contrast baths indication

Answer 14

treat subacute swelling,
gravity-dependent swelling,
vasodilation-vasoconstriction response.

Question 15

indication for Cryo-cuff (device that uses both cold and compression simultaneously)

Answer 15

acutely following injury and postsurgically.
It is made of a nylon sleeve that connects via a tube to a 1-gallon cooler/jug.
Cold water flows into the sleeve from the cooler. As the cooler is raised, the pressure in the cuff is increased.

Question 16

indications for Cryokinetics: (technique that combines cryotherapy with exercise)

Answer 16

numb the injured part to the point of analgesia and then work toward achieving normal range of motion through progressive active exercise.

Question 17

how does cryotherapy affect metabolism

Answer 17

to lower the temperature in the injured area, thus reducing the metabolic rate with a corresponding decrease in production of metabolites and metabolic heat.

helps the injured tissue survive the hypoxia and limits further tissue injury.

Question 18

when is cryotherpy used

Answer 18

acute stages of the healing process immediately following injury

Question 19

how does cryotherapy affect vessels during acute injury

Answer 19

used immediately after injury to decrease pain and promote local vasoconstriction, thus controlling hemorrhage and edema.

Question 20

how does cryotherapy affect inflammation

Answer 20

used in the acute phase of inflammatory conditions, such as bursitis, tenosynovitis, and tendinitis, in which heat may cause additional pain and swelling.

Question 21

how does cryotherapy affect muscle spasms

Answer 21

reducing muscle spasm.

Question 22

Contraindications: (6)

Answer 22

⦁ Impaired circulation.
⦁ Peripheral vascular disease (Raynaud’s phenomenon).
⦁ Hypersensitivity to cold.
⦁ Skin anesthesia.
⦁ Open wounds or skin conditions (cold whirlpools and contrast baths).
⦁ Infection.
