Moderate Protection; Controlled Motion

Answer 5

Phase: Proliferative
Stage: Subacute

Question 6

What phase and stage of these PT Goals of?

• increase tissue extensibility

minimum to no protection; return to function

Answer 6

Phase: Maturation
Stage: Chronic

What phase and stage of these Interventions of?

• Cold

Control effects of inflammation; prevent deleterious effects of rest

Answer 7

Phase: Inflammatory
Stage: Acute

Question 8

What phase and stage of these interventions of?

• superficial heat

develop mobile scar

Answer 8

Phase: Proliferative
Stage: Subacute

Question 9

What phase and stage of these interventions of?

• Heating

increase tensile quality of scar

Answer 9

Phase: Maturation
Stage: Chronic

Question 10

What phase is characterized by vascular increases in permeability and the resultant swelling?

Answer 10

Inflammatory

Question 11

In which stage do cells (macrophages and neutrophils) migrate to the site of tissue repair?

Answer 11

Proliferative

Question 12

In which stage of blood-borne proteins (fibrinogen and fibronectin) aggreated in the involved area

Answer 12

Proliferative

Question 13

Are the following local or systemic factors affecting healing?

• type, size, and location of injury
• infection
• vascular supply
• movement/excessive pressure
• temperature and deviation
• topical medications
• electromagnetic energy
• retained foreign body

Answer 13

Local

Question 14

Are the following local or systemic factors affecting healing?

• age
• infection or disease
• metabolic status
• nutrition
• hormones
• medication
• fever
• oxygen

Answer 14

Systemic

Question 15

Which tissue is this?

• lacks lymphatics, blood vessels and nerves and has a limited ability to heal
• injuries here involved subchronical bone allow inflammatory cells from bone to gain access to repair injured tissue

Answer 15

Cartilage

Question 16

What tissue is this?

posses a unique scar maturation phase that can achieve an advanced state of repair

Answer 16

tendons

Question 17

What tissue is this?

heal better with controlled passive mobilization

Answer 17

Ligaments

Question 18

What tissue is this?

• can be injured by trauma, strain or muscel diseases
• healing can occur through stem cells and can proliferate and differentiate in some cases
• severe contusion, myositis ossificnas (calcified hematoma) may develop here

Answer 18

Skeletal muscle

Question 19

Which stage of bone healing is this?

• begins shortly after impact
• creates hematoma, disrputs blood supply, lowers pH

Answer 19

Inflammation

Question 20

Which stage of bone healing is this?

• begins after swelliing subsides
• stabilizes fracture, decreases pain, and reduces chance of fat embolism

Answer 20

Soft callus

Question 21

Which stage of bone healing is this?

• 3 weeks - 4 months
• corresponds to clinical healing period

Answer 21

Hard callus

Question 22

Which stage of bone healing is this?

• takes months to years
• healed fibrous bone is converted to lamellar bone, and medullary canal becomes patent again

Answer 22

Bone remodeling
