1

What are the timeframes of acute, subacute and chronic injuries?

Acute: 0-6 weeks
Subacute: 5-12 weeks
Chronic: 6+ weeks

2

What type of health facilities would subacute patients be referred to?

Rehab centre, palliative care, convalescence

3

When does a scar occur?

When there is more than 33% damage and when it takes longer than 3 weeks to heal

4

What is the normal healing time for skin?

2-3 weeks, stitches out day 7-10, scar management day 10-18 months

5

What are three types of scars?

Normal, hypertrophic, keloid

6

How are muscle tears classified?

Grade 1: Sprain/strain (few fibres)
Grade 2: Disruption (bleeding, dysfunction)
Grade 3: Complete tear, requires surgery

7

What is the acute treatment for Grade 1 & 2 tears?

RICE, gentle mobilisation within first week

8

What does rehab for muscle tears involve?

ROM, stretching, strengthening, core work, coordination work

16

What are ligaments and tendons made up of?

Collagen bundles with few blood vessels

17

What is the paratendon?

Surrounds the whole tendon, contains most of the blood vessels and nerves
