Q

do all injuries recover in the same amount of time?

A
  • different injuries take different periods of time to recover
  • muscles recover quicker than ligaments and tendons due to higher blood supply and content of cells that repair

Q

what are the two management processes used in the inflammatory phase?

A
  • PEACE
  • LOVE
17
Q

what does PEACE stand for?

A

Protection
Elevation
Avoid anti- inflammatory
Compression
Education

18
Q

how do you protect?

A
  • avoid activities and movements that increase pain during first few days
19
Q

describe elevation

A
  • elevate injured limb higher than heart as often as possible
20
Q

why should you avoid anti- inflammatory medicine?

A
  • as they reduce tissue healing
  • no icing
21
Q

what do you use for compression?

A
  • use elastic bandage or taping
  • reduces swelling
22
Q

what is the importance of education ?

A
  • avoid unnecessary passive treatments as body knows best
23
Q

what does LOVE stand for?

A

Load
Optimism
Vascularisation
Exercise

24
Q

describe load

A
  • let pain guide your gradual return
25
Q

what does optimism mean?

A
  • condition your brain for optimal recovery by being confident and positive
26
Q

what is vascularisation?

A
  • choose pain- free cardiovascular activities
    ^ blood to repairing tissues
27
Q

what does exercise restore?

A
  • restores mobility, strength and proprioception by adapting an active approach
28
Q

what does large amount of inflammatory exudate contain? what does this do?

A
  • contains lots of fibrins
  • coats structures and becomes organised into scar tissue in unwanted places
29
Q

what does large amounts of inflammatory exudate in joints cause?

A
  • thickened, contracted joint capsule or adhesion formation
30
Q

what is not used in the inflammatory process?

A
  • ice
31
Q

what should you keep an eye on in inflammation stage?

A
  • check joints, swelling, amount of pain and functional loss
  • ensures inflammation hasn’t got worse
32
Q

what treatment do you use in the proliferation phase?

A
  • protection and optimal loading
33
Q

what treatment do you use in the remodelling phase?

A
  • optimal load
34
Q

what does chronic inflammation cause? what could occur?

A
  • causes continuous pain, swelling and lack of function
  • could occur with no preceding acute inflammation
35
Q

what does chronic inflammation involve?

A
  • adhesions and fibrosis
  • pathological remodelling
36
Q

what is gradually causes chronic inflammation?

A
  • gradual avascularisation of fibrous tissue
  • becomes scar tissue
  • shrinkages as ages
  • leads to contractures
