NPTE - Therapeutic Modalities: Cryotherapy, Superficial and deep thermotherapy, Hydrotherapy Flashcards
Indications for use of modalities (4)
- Pain
- Inflammation and repair
- Restriction in motion
- Abnormal tone
Principles of Heat Transfer: (5)
- Conduction
- Convection
- Conversion
- Evaporation
- Radiation
Conduction
Gain or loss of heat resulting from direct contract between tow materials at different temps
Convection
The gain or loss of heat resulting from air or water moving in a constant motion across the body
- Capable of transferring large amounts of heat
Conversion
Heating that occurs when nonthermal energy (e.g. mechanical, electrical) is absorbed into tissue and transfored into heat
Rate of heat transfer with conversion is determined by:
The power of the energy source
Evaporation
Transfer of heat that occurs as a liquid absorbs energy and changes form into a vapor
Radiation
Direct transfer of heat from a radiation energy source of higher temp to one of cool temp
Rate of heat transfer with radiation is influenced by:
- Intensity and size of the energy source
- Target area
- Angle of the radiation to the target area
- the distance between the energy source and target area
Cryotherapy
Local or general use of low temperatures in rehab
Generates therapeutic effects by influencing hemodynamic (blood flow), metabolic (metabolic rate), and neuromuscular processes (nerve conduction)
Therapeutic Effects of Cryotherapy (7)
- Decreased blood flow to treatment area
- Decreased edema
- Decreased local temp
- Decreased metabolic rate
- Decreased nerve conduction velocity
- Decreased tone
- Increased pain threshold

Indications for Cryotherapy (9)
Contraindications of Cryotherapy (10)
- Cold intolerance
- Cold urticaria
- Cryoglobulinemia
- Infection
- Over an area of compromised circulation
- Over regenerating peripheral nerves
- Paroxysmal corl hemoglobinuria
- Peripheral vascular disease
- Raynaud’s phenomenon
- Skin anesthesia
Ice massage
Applied directly to the treatment area
Ideal for small or contoured areas
Easily intigrated into an HEP
Pt in relaxed position, ideal elevated
Cold Pack
Should be cooled for at least 30 min between uses and 2+hrs before initial use
Should be applied over a moist towel
Approximately 20 min application
Can be applied every 1 to 2 hrs for inflammation and pain control
Extend to 30 min if goal is spasticity reduction (skin requires inspection every 10 min!)
Cold Bath
Used for the immersion of the distal extemities
Allows for circumferential contact
Temps ranging from 55-64°F
15-20 min
Lower temp = shorter tx time
Controlled Cold Compression Unit
Circulates cooled water through a sleeve that is applied to an extremity
Temps ranging from 50-77°F
Combination is more effective than cold or compression alone in controlling inflammation
