Strand 3 (Injury & Healing Process) Flashcards
Acute Injury
Injury with sudden onset with a definite time of occurrence
Ex: Sprained Ancle, Torn ACL
Chronic Injury
Injury from prolonged overuse
Ex: Shin Splints, Osgood Schlatters
Inflammation is…
The body’s normal response to injury
3 Phases of Healing
Acute, sub-acute & remodeling
Acute Phase: Alternate Name
Inflammation
Acute Phase: Time Frame
2-3 days
Acute Phase: what is happening?
Blood vessels are ruined (hypoxia), pain, swelling, redness, loss of function
Sub-Acute Phase: Alternate Name
Repair & Regeneration
Sub- Acute Phase: Time
3-4 weeks
Sub-Acute Phase: what is happening?
Cellular debris cleared, normalize blood flow, regeneration of tissue
Remodeling Phase: Alternate Name
Maturation
Remodeling Phase: Time
1 year
Remodeling Phase: what is happening?
Activity of fibroblasts decreases, collagen fibers strengthen and attempt to align with existing fibers
Signs of Inflamation (5)
Redness, heat, swelling, pain, loss of function
Causes of Pain (2)
Processes that contribute to Swelling (4)
