Study Notes
Creep in Connective Tissue
- Permanent deformation of connective tissue occurs when a stress is applied for an extended period, resulting in elongation.
- Creep is related to the viscosity of the tissue and is therefore time-dependent.
- The amount of deformation depends on the amount of stress and the rate at which the stress is applied.
Factors Affecting Creep
- Low-magnitude loads, within the elastic range, and applied for long periods increase deformation of connective tissue.
- This leads to gradual rearrangement of collagen fiber bonds (remodeling) and redistribution of water to surrounding tissues.
Temperature and Creep
- Increasing the temperature of the affected part increases creep and therefore the distensibility of the tissue.
- Physical therapists use heating methods, such as moist heat (towels) or infra-red radiation, before stretching to take advantage of this phenomenon.
