Collagen, Healing And Mobilisations

Question 1

What are the tissue repair phases

Answer 1

Bleeding, inflammation, proliferation, remodelling

Question 2

What happens in the late proliferation/ remodelling stage on a cellular level?

Answer 2

Fibroblasts produce collagen fibrils (type1)

Fine, easily broken- like candy floss, high blood content

Question 3

Main characteristics and time frame of remodelling stage?

Answer 3

May last up to 12/12
Fibroblast activity decreases
Collagen fibres mature (type2), thicken and shorten
Scar will contract over time

Question 4

Why does injury effect immobilisation?

Answer 4

Irregular collagen fibre arrangement
More random cross links between fibres and other tissue structures
Fibres won’t slide past each other correctly
Inappropriate shear forces more likely as fibres not longitudinally aligned over their long axis
Results in incorrect movement patterns across joints

Question 5

Why is it important to treat areas once healed?

Answer 5

If left untreated, permanent shortening of muscles, ligaments, tendons, joint capsule

Question 6

What are the main effects of mobilisations?

Answer 6

Mobilising injured tissues during the early remodelling stage will stress collagen fibres, encourage appropriate realignment of individual fibres, restore normal structure resulting in normal function
