Q

how long does it take hot pack to get skin to its max

17
Q

do contrast baths or ice packs get more intramuscular temperature change

18
Q

T/F evidence of reduction in local oedema from contrast baths

A

no but evidence in decrease in mm soreness

19
Q

ratio hot to cold

A

4:2 mins or 5:3 or 3:1
repeat 3-4 times
20-30 mins max

20
Q

effects of whirlpool baths

A

water agitation stimulates skin

gently debrides wounds for learning of dirt/necrotic tissue

21
Q

precautions with superficial heat

A

local burns
altered sensation
altered heat loss mechanism (obese)

infection
skin diseases (eczema)
open wounds
unreliable patients

22
Q

indications for superficial heat

A
reduce pain
increase ROM
reduce mm spasm 
increase exercise tolerate 
fine motor movements
23
Q

what is the extent of temperate change in tissues dependent on

A

rate of heat energy removal
amount of heat energy removal

body part
towel
size of area
duration

24
Q

what types of cold recommended

A

crushed n cryo

25
does cold help metabolic reduction
current research says no
26
POLICE
``` Protect optimal loading ice compress elevation ```
27
therapeutic uses of cooling
``` promote healing pain reduction dec swelling dec mm spasm dec spasticity mm strengthening chronic inflammatory conditions ```
28
how to apply ice
check at 1 and 5 minutes
29
when can you do continuous immersion for cold when can you do 1 minute
16-28 degs lets you do 15-20 minutes 10 lets you do 1 minute
30
any evidence begining in either hot or cold
none
31
benefits of ice towels
you can move or exercise while applied switch towels 2-3 minutes
32
benefits of ice massage
improves mm function | greater intramuscular cooling than ice packs
33
dangers /contraindications for ice
ice burn frostbite open wounds vasospasm (raynauds)
34
why open wounds bad w ice
may reduce vascular supply to area to delay repair
35
cold urticaria
degranuatlion of mast cells, release histamine
36
how to check skin testing
hot n cold sticks and capillary fill rate ice cube test
37
disadvantages of cold
increase stiffness | decrease tissue extensibitly
