1
Q

where is the greatest effect superficial heating

A

1-2mm

2
Q

how long for heat to reach 2cm

A

20-25 mins and only 1 deg increase

3
Q

6 Therapeutirc effects of superficial heating

A

TIIRRS

Tissue healing
increase ROM
Infection control
Relief of Pain
Reduction of mm spasm
Sedative
4
Q

T/F heat in inflamattroy stage is beneficial

A

no, but mild heating after initial risk of further bleeding can stimulate early repair tho

5
Q

T/F chronic inflammation can be treated w heat

A

true, with exercise and stretch

6
Q

why does tissue healing happen with heat

A

inc blood flow, inc leukocytes, antidotes, nutrients oxygen

remove by products of inflammatory response

7
Q

does superficial heat help sympathy or para sympathetic nervous system

A

Sympathetic

8
Q

how does heat reduce mm spasm

A

reducing ischaemia associated with prolonged contraction

9
Q

why joint increase in ROM after heat

A

analgesic effects increase tolerance of stretch

collagen tissue extensibitly increases at higher temperatures

10
Q

therapeutic effets of heat depend on

A
extent of temperate increase
modality, blood flow
rate of which heated
volume of tissue heated
composition of tissue
11
Q

what temperature do you see therapeutic effects

A

40-45C

12
Q

how long can you tolerate 45 c, 50c, and 65s

A

1 hr
1 minute
1 secon

13
Q

dangers of wax

A

don’t enter open wound
skin infections
acute inflammation
fire blanket extinguisher closer

14
Q

types of hot packs

A

hydrocollator (wax), microwavable (gel), disposable (warmers)

15
Q

what do you not do with hot packs

A

lie on it

16
Q

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

A

8 mins

17
Q

do contrast baths or ice packs get more intramuscular temperature change

A

packs

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
Q

does cold help metabolic reduction

A

current research says no

26
Q

POLICE

A
Protect
optimal loading
ice
compress
elevation
27
Q

therapeutic uses of cooling

A
promote healing
pain reduction 
dec swelling
dec mm spasm
dec spasticity
mm strengthening 
chronic inflammatory conditions
28
Q

how to apply ice

A

check at 1 and 5 minutes

29
Q

when can you do continuous immersion for cold

when can you do 1 minute

none

31
Q

benefits of ice towels

A

you can move or exercise while applied

switch towels 2-3 minutes

32
Q

benefits of ice massage

improves mm function

greater intramuscular cooling than ice packs

33

vasospasm (raynauds)

34
Q

why open wounds bad w ice

A

may reduce vascular supply to area to delay repair
