Flashcards in Healing Deck (18)
What factors impede healing?
Health Status of individual (ie.diabetes)
Medications (ie. anti-coagulants, corticosteroids, NSAIDs)
What are the 3 phases of healing?
Proliferation (fibroblastic remodelling)
Maturation (differs for every individual)
How do you describe the inflammatory phase?
Loss of Function
What is the 1st mechanism of the inflammatory phase?
-reduction in volume of blood flow promotes increased blood cell viscosity or resistance to flow
What is the 2nd mechanism of the inflammatory phase?
-provokes clotting as individual cells combine w/each other & fibrin to form mechanical plug
- prevents invasion from other foreign bodies & bacteria
What is the 3rd mechanism of the inflammatory phase?
-brings neutrophils & macrophages to rid the area of debris & infectious agents through phagocytosis
- ⬆️ blood flow to area causes swelling
What happens during the Proliferation phase?
Involves repair & regeneration of injured tissue & takes approx. 3 days post injury through the next 3-6 weeks
- new blood vessels develop (angiogenesis)
- fibrous tissue formation (fibroplasia)
- generation of new epithelial tissues (re-epithelialization)
- wound contraction
What happens during the Maturation phase?
Involves maturation of newly formed tissue into scar tissue
- fibroblastic activity
- increased organization
- decreased tissue water content
- reduced vascularity
- return to normal histochemical activity
Scar tissue tends to be....
Less strong & less functional than original tissues
Development of scar typically causes wounds to shrink, resulting in ⬇️ flexibility of affected tissues
What is proprioception?
Ability to determine the position of a joint in space
What is Kinesthesia?
Ability to detect movement
What is Physiological Movement?
Results from active muscle contraction which are voluntary
(Flex, ext, rot, abd, add)
What are Accessory Movements?
Manner in which one articulating surface moves relative to the other (roll,spin,glide)
Necessary for full ROM to take place
What is a concentric muscle contraction?
Muscle fibres contract while shortening
What is eccentric muscle contraction?
Muscle fibre contract while lengthening
- critical for deceleration of limb motion
( baseball pitchers need eccentric lateral rot. strengthening
-also use plyometric
-very tough on tissue & is done in the maturation/remodelling stage
What is isokinetic muscle contractions?
Fixed speed w/ accommodating resistance
Incorporated during the later stages of proliferation phase
Can also be used for objective measurements of strength, endurance & power ratios
When are isometric contractions used?
-Early stages of rehab (after inflammation) & during immobilization
-Useful when full ROM will do further damage to injured tissue
-Increase static strength
-muscle pumping action (I.e. W/ankle swelling)
