Tissue strain from Tissue Velocity Imaging (TVI) during sub-maximal isotonicmuscle contractions

摘要

We have used Tissue Velocity Imaging (TVI) as a method to quantify the deformation of skeletal muscle tissue during contraction. The parameters used to describe tissue dynamics in this study were strain and strain rate, respectively. Eight subjects were evaluated performing submaximal isotonic contractions of biceps brachii before and after muscle fatigue.
