Concepts of Healing - Test 1 Flashcards
What is the best treatment during the inflammation phase?
Therapeutic Modalities
Which type of Collagen is stronger?
Type I
What is angiogenesis?
Growth of new blood vessels
What is the best treatment during the rehabilitation phase?
Strength Training Exercises
During remodeling phase, type __ collagen is broken down and is replaced by type __ collagen.
Type III
Type I
What is tensile strength of a wound directly related to?
amount of collagen present
What is/are the causes of pain during the inflammation phase of healing?
Edema putting pressure on nerve endings
Chemical Mediators increasing the sensitivity of nerve endings
When is collagen produced?
Proliferation Phase
What are factors that affect healing?
Treatment modalities Drugs/NSAIDs Age Disease Wound size Surgical Repair Infection Nutrition Swelling Muscle Spasms
Immobilization of injured tissue will ___ cross-link formation and cause restricted ROM.
Increase
What are effects of periarticular connective tissue immobilization?
Thickening and fibrotic connective tissue
Diminished extracellular matrix water content
During what phase of healing would PROM and/or AROM techniques e best at limiting edema formation and the effects of immobilization?
Inflammation
During immobilization, what causes an increase in fibrosis tissue to form?
Prolonged edema
Define Elasticity.
Ability to return to normal length after an elongation force or load has been applied.
Define Viscosity.
The resistance to an outside force that causes a fluid-like, permanent deformation.
Define Viscoelasticity.
The ability of a structure to resist change but inability to completely return to its former state.
Define Plasticity.
The ability of a substance to undergo a permanent change in size or shape after a force is applied.
During what phase of healing would collagen be less influenced by attempts to increase ROM?
Late remodeling
During what phase of healing would flexibility techniques be best to limit or breakdown cross-link formations?
Proliferation
What are the effects of muscle immobilization?
Reduction of muscle fiber size
Reduction of myofibrils
Decrease ATP production
Decreased oxidative capacity
