CT and Inflammation Flashcards
Creep, hysteresis, and set are all examples of…
changes that can occur in the connective tissues with loading and unloading
Connective tissue deformation can be due to…
posture, repetitive motions, ADLs, etc.
Macro or microtrauma
What is creep?
Progressive deformation (change in length) of a viscoelastic structure when a sustained force is applied to it
Which structures can be affected by creep?
Ligaments, capsule, disc, fascia
Creep involves gradual rearrangement of…
collagen, proteoglycans, and water
Effects of creep vary with…
age, injury, and disease
What can lead to creep?
- ADLs (especially if performed with poor body mechanics)
- Postural syndromes
- Lifestyle habits
- Work specific activities/positions
What is hysteresis?
Deformation of tissue from repeated loading and unloading
Hysteresis reflects ___ due to ___
loss of energy due to strain placed on the tissue
With hysteresis, strain is placed on which parts of the tissue?
Collagen, proteoglycans, and water content
What can lead to hysteresis?
- ADLs
- Lifestyle habits
- Work specific activities
What is set?
The measurable difference between the original shape or length of the tissue and the final shape or length of the tissue
Following changes, the tissue is more…
susceptible to injury
Is restoration and rearrangement of collagen and proteoglycans possible?
Yes, over time
Changes in the arrangement and behavior of tissues can affect future…
response to tissue deformation
