• atrophy
• corticosteroids
• keloids and hypertrophic scars
• infection
• humidity, climate, oxygen tension
• health, age, nutrition

Question 6

How long does it take for a ligament to heal?

Answer 6

full healing of a ligament may require 12 months

Question 7

True or false: exercised ligaments are stronger

Answer 7

true

Question 8

How long does it take for skeletal muscle to heal?

Answer 8

6-8 weeks depending on which muscle was injured

Question 9

True or false; injured central nervous system nerves heal at the same rate as peripheral nerves

Answer 9

false

injured CNS nerves do NOT heal as well as peripheral nerves

Question 10

What are NSAIDS and give examples of some common types

Answer 10

Non-steroidal anti-inflammatory drugs

eg., aspirin, ibuprofen, naproxen

Question 11

What are the stages of acute fractures?

Answer 11

• hematoma formation
• cellular proliferation
• callus formation
• ossification
• remodelling

Question 12

How long does it take for bone to heal?

Answer 12

3-8 weeks

Question 13

Where are common sites for stress fractures? (7 points)

Answer 13

• tibia
• MTs
• fibula
• femur
• calcaneus
• ribs
• humerus

Question 14

Clot formation is part of Phase ___ (1/2/3) and begins around ____ hours post injury and completed within _____ hours

Answer 14

1, 12, 48

Question 15

Which phase does scar begin to develop?

Answer 15

Phase II: Fibroblastic Repair

Question 16

True or false: Fibroblastic repair phase starts when macrophages have finished

Answer 16

true

Question 17

True or false; exercised ligaments are weaker due to increased stretch and thus leads to instability of the joint

Answer 17

false; exercised ligaments are stronger

Question 18

What are some exercise methods to modify soft-tissue healing?

Answer 18

• increase ROM
• increase strength and endurance
• limit atrophy

What are the 5 stages of acute fractures?

Answer 19

1 - hematoma formation 
2 - cellular proliferation 
3 - callus formation 
4 - ossification 
5 - remodelling

Answer 20

3-8 weeks

Question 21

true or false; in the event of bone fracture, bone must not be immobilised and client must do exercise ASAP

Answer 21

false; client must be immobilised until X rays reveal the presence of a hard callus

Question 22

true or false; fractures can limit participation for weeks or months

Answer 22

true
