Biomechanics Terminology: Viscoelasticity

Biomechanics Terminology: Viscoelasticity In this 18-minute mini-lecture, I discuss how our body's structural tissues, including bone, cartilage, muscle, tendon, ligament, fascia and skin,all exhibit time-dependent load vs deformation characteristics called viscoelasticity. All the structural tissues of the body have both elastic and fluid (i.e. viscous) properties and as such, when loaded by tension, compression, torsional, shear or bending forces, they will deform more over time or, in other words, will show time-dependent load-deformation characteristics. Included within this discussion is the histology of viscoelasticity, the important time-dependent concepts of creep response, stress relaxation and strain rate dependence, along with a short discussion of viscoelastic models and hysteresis. A better understanding of viscoelasticity and how these load-deformation characteristics of our body's tissues affect the function of the foot and lower extremity is vitally important for the podiatrist and foot-health professional to gain a full appreciation of the biomechanics of injury of the foot and lower extremity.
