Q

what cools better and why, conduction or convection?

A

convection such as whirlpool because it continuously cycles cold water to pull heat from the body

Q

how does vapocoolant work (4 steps)

A
  1. heat tx to liquid to vapor
  2. spray stimulates thermal afferents
  3. reduced motor neuron activity
  4. increased ROM

Q

what is the hemodynamic effect of cold?

A
  1. cold applied
  2. vasoconstriction and increased blood viscosity
  3. decreased in bloodflow
17
Q

how does vasoconstriction occur?

A

cold stimulates thermal sensors which leads to INCREASED SYMPATHETIC ADRENERGIC fiber response

18
Q

how does vasodilation occur?

A

cold stimulates thermal sensors which leads to DECREASED SYMPATHETIC ADRENERGIC fiber response

19
Q

describe ice’s use post-trauma

A

reduces inflammation in the first 48, compression and elevation help with edema, overwhelmingly safe to use

20
Q

how does cold influence muscle contraction?

A

brief periods of cold (less than 10 min) may increase isometric contraction

21
Q

how does cold influence performance?

A

10+ min of cooling diminishes performance (40 yd dash, vert, agility)

22
Q

how does cold impact joint position sense?

A

decreases balance but doesn’t effect proprioception

23
Q

how do cold modalities have neuromuscular effects?

A

decrease spasticity, deep tendon reflexes, and muscle spindle activity

24
Q

how does cold affect MS patients?

A

improves balance and TUG while wearing a cooling vest

25
Q

what is megan’s sports team

A

steelers

26
Q

when do you choose ice? (5)

A 
acute msk trauma
pain
spasm
myofascial pain
guarding
27
Q

is ice good for DOMS

A

no, no evidence

28
Q

what are the six contraindications for cold

A
  1. cold urticaria
  2. cryoglobulinemia
  3. raynauds
  4. paroxysmal cold hemoglobinuria
  5. area of nerve regen
  6. area of compromised circulation
29
Q

what are seven precautions for cold

A
  1. HTN
  2. hypersensitivity
  3. circulation
  4. wound
  5. superficial peripheral nerve
  6. cold aversion
  7. poor cognition/comm
30
Q

why is ice more effective than gel?

A

takes more energy to melt ice

31
Q

how long to ice massage?

A

5-8 min

32
Q

how do you use vapocoolant? does it work?

A
  1. hold 12-18 inches
  2. spray proximal to distal
  3. stretch

no proof it works

33
Q

how cold is the water in a cold bath?

A

50-60 F

34
Q

what MUST you do after applying a modality

A

reassess pain/ROM and document

35
Q

what are the stages of cold

A 
cold
stinging
burning
aching
numbness
