heat therapy & cryotherapy Flashcards
heat therapy modalities (6)
warm whirlpool infared heat w/ solux lamp hotmud warmhydrocollator packs paraffin baths fluidotherapy
what is Warm whirlpool
postsurgical modality to increase systemic blood flow and mobilization of the affected body part.
Infrared heat with a Solux lamp
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.
Paraffin baths
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.
Fluidotherapy
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.
uses of heat therapy
- reduction of pain and inflammation in subacute conditions
- improves blood flow thus improving tissue injury
- increases local metabolic rate which in turn produces more heat improving blood flow and supply of oxygen, wbc and nutrients
- relaxation and decreases guarding of skeletal muscles so can be used in strains and sprains and muscle spasms
Contraindications
⦁ Acute musculoskeletal conditions. ⦁ Impaired circulation. ⦁ Peripheral vascular disease. ⦁ Skin anesthesia. ⦁ Open wounds or skin conditions.
what is cryotherapy
tissue temperature decrease for a variety of therapeutic purposes
cryotherapy modalities (8)
⦁ Cold spray ⦁ Cold hydrocollator packs ⦁ Cold or ice whirlpool ⦁ Ice packs ⦁ Ice massage. ⦁ Ice immersion ⦁ Contrast baths ⦁ Cryo-cuff ⦁ Cryokinetics
indication for the use of Cold hydrocollator packs
indicated in any acute injury to a musculoskeletal structur
indication for the use of Ice packs
indicated in acute stages of injury, as well as for prevention of additional swelling after exercise of the injured part.
indication for the use of Cold or ice whirlpool
indicated in acute and subacute conditions in which exercise of the injured part during a cold treatment is desired.
Cold spray
such as Fluori-Methane, do not provide adequate deep penetration,
provide adjunctive therapy for acupressure techniques to reduce muscle spasm.
Contrast baths indication
treat subacute swelling,
gravity-dependent swelling,
vasodilation-vasoconstriction response.
indication for Cryo-cuff (device that uses both cold and compression simultaneously)
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.
indications for Cryokinetics: (technique that combines cryotherapy with exercise)
numb the injured part to the point of analgesia and then work toward achieving normal range of motion through progressive active exercise.
how does cryotherapy affect metabolism
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.
when is cryotherpy used
acute stages of the healing process immediately following injury
how does cryotherapy affect vessels during acute injury
used immediately after injury to decrease pain and promote local vasoconstriction, thus controlling hemorrhage and edema.
how does cryotherapy affect inflammation
used in the acute phase of inflammatory conditions, such as bursitis, tenosynovitis, and tendinitis, in which heat may cause additional pain and swelling.
how does cryotherapy affect muscle spasms
reducing muscle spasm.
Contraindications: (6)
⦁ Impaired circulation.
⦁ Peripheral vascular disease (Raynaud’s phenomenon).
⦁ Hypersensitivity to cold.
⦁ Skin anesthesia.
⦁ Open wounds or skin conditions (cold whirlpools and contrast baths).
⦁ Infection.
