Modalities Flashcards
Chemical activity in cells and metabolic rate will increase ___ for each ___ rise in temperature.
2-3 times; 10 deg C
temperature after which tissue will burn
45-50 deg C
use of heat modality (3)
- increase interstitial fluid and cause mild edema
- decrease pain
- in combination with stretch
superficial heat (3)
heats tissue within 0.5 cm from the surface
- hot packs
- paraffin
- fluidotherapy
moist heat pack
kept in ~160 deg F water
usual multiple layers of towel or cover and towel
needs 30 to reheat when returning to water
check after 5 min
15-20 min
DO NOT LIE ON TOP OFF
paraffin (4)
superficial, moist heat most commonly used for distal extremity
- dip and wrap - elevate hand
- dip and reimmerse - rarely used
- paraffin ‘packs’
- cooled paraffin - used for closed skin grafts
fluidotherapy
dry heat
temp and agitation can be controlled
usually 115-117 deg F
allows patient to exercise while heating
contraindications/precautions for superficial heat (5)
- circulatory impairment
- cancer at site of heat application
- sensation impairment
- easy bleeding
- infection
home program options - heat (3)
- heating pad
- microwave gel pads
- rice socks
use of cold modality (4)
- used in acute stages of inflammation
- reduction of muscle spasms
- reduction of pain
- decrease swelling
cold modalities (2)
- cold packs
2. ice massage
precautions for cold modalities (2)
- patients with cold-sensitivity (ex. Raynaud’s)
2. patients with circulatory-compromised areas
documentation of temperature modalities (4)
- thermal agent used
- duration
- body area treated
- position
ultrasound
deep heating agent
water-based gel used as a couple
uses of ultrasound (6)
- joint contracture
- scar tissue
- tendinitis
- bursitis
- muscle spasms
- pain
ultrasound - frequency
of oscillations a molecule undergoes in 1 second
1.0 MHz, 2.0 MHz, 3.0 MHz are used in therapy
frequency determines the depth of penetration
ultrasound depth with 1 MHz frequency
2-5 cm
ultrasound depth with 3 MHz frequency
up to 2 cm
ultrasound tissues (3)
US is absorbed in tissue high in protein (collagen)
- tendon
- ligament
- joint capsule
ultrasound wave settings (2)
- pulsed waves
2. continuous waves
pulsed ultrasound
used when the desired effect is non-thermal such as acute soft tissue injuries
