Age-related changes of Shearwave velocity in healthy middle-aged adults

October 2013 to June 2014

Shearwave velocity may serve as a quantitative biomarker to asses tendon disease.
The Achilles tendon is the largest and most commonly injured tendon in the body.
We have studied shearwave velocity in a cohort of young healthy subjects between
the ages of 18-41. We found that shearwave velocity changes in different parts of
the Achilles tendon and in different positions of the ankle (dorsilflexed vs.
plantar flexed). We hypothesize that shearwave velocity
will be different (decreased) in an older population of healthy adults.
