Acute

30
Q

What are the 3 stages of inflammation and repair?

A

1) Acute Stage (Inflammatory Reaction)
2) Subacute Stage (Repair & Healing)
3) Chronic Stage (Maturation & Remodelling)

31
Q

Signs of inflammation (e.g. swelling, redness, heat, pain at rest, loss of function) are present in this stage. Movement is painful and the patient usually guards against motion before completion of range (pain before tissue resistance).

A

Acute Stage (Inflammatory Reaction)

32
Q

Pain and impaired movement in the _____ stage are from the altered chemical state that irritates the nerve endings, increased tissue tension due to edema/joint effusion and muscle guarding (spasm). This is the body’s way of ____________ the painful area.

A

Acute
Immobilizing

33
Q

The acute stage (inflammatory reaction) usually lasts __ to __ days, unless the injury is aggravated.

A

4-6 days

34
Q

Signs of inflammation progressively decrease and eventually disappear. Revascularization is occurring and fibroblasts produce collagen which mends the tissue, however it is still fragile and easily damaged.

A

Subacute Stage (Repair & Healing)

35
Q

Immature connective tissue is thin and unorganized in the ________ stage and proper growth/alignment can be stimulated by appropriate tensile loading. Collagen fibres will align according to the ________ placed upon them.

A

Subacute
Stresses

36
Q

In the ________ stage, new tissue may adhere to surrounding structures, which can:
- Restrict ROM
- Become a source of pain
- Impair circulation to the tissue

A

Subacute

37
Q

T/F - At the end of the chronic stage, a stable scar is formed.

A

False - At the end of the SUBACUTE stage, a stable scar is formed.

38
Q

With ROM testing in the ________ stage, pain may be experienced synchronous with tissue resistance towards the end of available range. Pain only occurs when the newly developing tissue is stressed and muscles may test ____ and function is limited as a result of the weakened tissue.

A

Subacute
Weak

39
Q

The subacute stage (repair & healing) usually lasts ___ to ___ days (14-21 days after the onset of injury). It may last up to __ weeks in some tissues with limited circulation (e.g. ligaments, tendons).

A

10-17 days
6 weeks

40
Q

No signs of inflammation are present in this stage and the molecular structure of collagen changes by becoming thicker and stronger.

A

Chronic Stage (Maturation & Remodelling)

41
Q

In the _______ stage, immature collagen can be remodelled with gentle persistent treatment ( __ to ___ weeks) and after 14 weeks, scar tissue is unresponsive to remodelling stresses.

A

Chronic
8-10 weeks

42
Q

Old scars do not respond well to __________ and require adaptive lengthening of surrounding tissues.

A

Stretching

43
Q

In the _______ stage, ther may be muscle weakness limiting normal function as well as contractures/adhesions that limit range. Connective tissue continues to strengthen and remodel.

A

Chronic

44
Q

With ROM testing in the _______ stage, stretch pain may be felt when testing tight structures at the end of their available range. Function may be limited by weakness, poor endurance or poor neuromuscular control.

A

Chronic

45
Q

The chronic stage (maturation & remodelling) may last __ months to __ year depending on the tissue involved and the amount of damage.

A

6 months-1 year

46
Q

What are the 3 levels of severity of tissue injury?

A

1) Grade 1 (First Degree)
2) Grade 2 (Second Degree)
3) Grade 3 (Third Degree)

47
Q

Grade __ severity of tissue injury involves:
- Mild pain at time of injury or within 24 hours
- Mild swelling, local tenderness & pain when tissue is stressed

A

Grade 1 (First Degree)

48
Q

Grade __ severity of tissue injury involves:
- Moderate pain that requires stopping the activity
- Stress & palpation of tissue greatly increase pain
- With injury to ligaments, some of the fibres are torn = increased joint mobility

A

Grade 2 (Second Degree)

49
Q

Grade __ severity of tissue injury involves:
- Near-complete or complete tear/avulsion of tissue (e.g. tendon, ligament) with severe pain
- Stress to tissue is usually painless
- Palpation may reveal the defect
- Torn ligament results in instability of joint

A

Grade 3 (Third Degree)

50
Q

T/F - Skin is intact with contusions common sites are soft tissue structures that are exposed to contact, as well as bony prominences.

A

True

51
Q

What are the 3 classifications of contusion injuries?

A

1) Mild
2) Moderate
3) Severe

52
Q

With a ____ contusion injury:
- 2/3 ROM available
- Minimal bleeding
- Minimal to no loss of function

A

Mild

53
Q

With a ________ contusion injury:
- 1/3-2/3 ROM available
- Some bleeding
- Difficulty with function

A

Moderate

54
Q

With a ______ contusion injury:
- < 1/3 ROM available
- Significant bleeding
- Very little to no function

A

Severe

55
Q

A swelling comprised of a mass of blood that is confined to an organ, space or tissue and caused by a break in a blood vessel. Usually a normal occurence with contusions. If palpable, it will feel like a hard lump at the lesion site and should resolve as injury heals.

A

Hematoma

56
Q

With significant ________, there is a risk of severe bleeding or re-bleeding. This is a feature of more severe contusions and we must use care during treatment.

A

Hematoma

57
Q

Bleeding is between the muscles. Blood disperses early and recovery is faster with less scar tissue.

A

Intermuscular Hematoma

58
Q

Bleeding occurs within the muscle (contained by fascia/surrounding tissue) and there is a longer recovery with more scar tissue formation. There is also a higher risk of developing myositis ossificans or compartment syndromes.

A

Intramuscular Hematoma

59
Q

Formation of osseous tissue within muscle (e.g. quadriceps, brachialis). Incidence increases with severity and/or repetitive contusions, along with poor treatment.

A

Myositis Ossificans

60
Q

We should be suspicious of _________ __________ (red flag), when there is an increase in pain, return of inflammation and increasing hardness of the hematoma.

A

Myositis Ossificans
