CH 4: Stretching of soft tissue contractures Flashcards
What do stretching of soft tissue contractures involve?
- Muscle
- Capsule
- Tendon
- Ligaments
- Bursa
- Skin
What type of stretching has been effective technique that produces long-lasting connective tissue changes?
Low-duration, low-load static stretching
What is a permanent or transient limitation of movement or shortening of muscles or soft tissue?
Contracture
What is the result of healed tissue that forms a fixed, rigid scar and causes cosmetic deformity or functional deficits?
Contracture
What involves a limitation of function resulting from scar tissue that forms between structures?
Adhesion
How many weeks is immature scar tissue adaptable?
8 weeks
When does a scar become a mature scar and less changeable (inadaptable)?
14 weeks
What type of scar is highly vascular with many cells (myofibrocytes) that give the scar the ability to contract?
Adaptable
What type of scar tissue has a high rate of remodeling?
Immature
What is the process of tissue restructuring in response to stress or stimulation?
Remodeling
As new scar tissue forms, what becomes highly unorganized and arranged randomly, creating an immobile structure?
Collagen
What type of scar tissue becomes increasing organized and oriented with specific directional lines of stress?
Adaptable or immature scar tissue
What forms in response to stress imposed from mechanical loads?
Collagen
What are the critical components where stretching is concerned?
- Time dependent, stress reactive nature of scar tissue
- Fragility of immature adaptable scar
- New scar tissue organizes and aligns itself along lines of stress, so appropriately place stress helps remodel
- Low load, long duration stretching combined with preheating the involved are to improve treatment
At 5 days, new scar is only ____ of its maximum potential strength?
10%
