What are the physiological effects of cryotherapy?
- Decreased circulation
- Local vasoconstriction
- Decreased inflammatory effects
- Decreased metabolism
- Increased tissue stiffness
- Decreased muscle spasm
- Decreased pain
- Decreased nerve conduction velocity
Cryotherapy is the modality of choice in __ trauma?
Acute
What are the indications of use for cryotherapy?
- Acute pain
- Acute inflammation
- Muscle spasm
- Acute sprains/strains
- Febrile states
- Insect bites
- Burns/boils
What are the contraindications for cryotherapy?
- Allergy to cold
- Reynaud’s disease
- Open wounds
- Peripheral vascular disease
- Local infection
- Over the heart
- Over a pregnant (gravid) uterus
- History of frostbite
What is the recommended treatment time for cryotherapy?
5 minutes (wait at least 60 minutes between treatments)
What are the four stages of cold?
- Cold (1-3 minutes)
- Aching/stinging/discomfort
- Pain/burning (2-7 minutes)
- Numbness (5-15 minutes)
What is the mode of heat transfer for cryotherapy?
Conduction
What is the amount of penetration for cryotherapy?
1/2 inch
How many towel layers must be placed between the cold pack and the patients skin?
1 moist towel layer
What are the physiological effects of superficial heat?
- Increased blood flow
- Increased cellular metabolic rate
- Increased inflammation and edema
- Increased risk of hematoma infection
- Promotes abnormal ossification
- May prevent adhesion formation
- Promotes reabsorption of hematomas
- Analgesic
What are the indications of use for superficial heat?
- Chronic pain
- Muscle spasm
- Vascular stasis
- General anxiety
What are the contraindications for superficial heat?
- Peripheral vascular disease
- Malignant neoplasm
- Local edema
- Skin rashes
- Decreased sensation
- Open wounds
- Over a pregnant (gravid) uterus
- Over an active infection
- Acute conditions
What is the recommended treatment time for superficial heat?
10-20 minutes
What is the mode of heat transfer for superficial heat?
Conduction
What is the amount of penetration for superficial heat?
1/4 - 1/2 inch
How many towel layers must be placed between the hot pack and the patients skin?
6-8 towel layers
What are the indications of use for microcurrent?
- Swelling
- Pain
- Wound healing
What are the contraindications for microcurrent?
- Cardiac arrhythmia
- Vascular disease
- Hypersensitivity
- Over a pregnant (gravid) uterus
- Implanted electrical devices
What are the methods of application for microcurrent?
- Pads
- Probes
- Electromassage
- Transcranial
What is the intensity for microcurrent when using probes?
350-550 uA
What is the frequency for microcurrent when using probes?
0.5-10 Hz
What is the polarity for microcurrent when using probes on an acute condition?
Positive
What is the polarity for microcurrent when using probes on a chronic condition?
Negative
What is “circle the dragon”?
The technique used when using probes, in which you treat at least 4-6 points for 10 seconds each (3 passes each treatment cycle)
