Research Abstract |
The purpose of this study was to determine the muscle fascicle behavior using high framerate ultrasound in the onset of voluntary muscle contraction. For this purpose, we usedlocal phase differences between successive raw radio frequency(r-f) signals of ultrasound. Authors could visualize the onset of fascicle movement in wider range of muscle comparedto previous studies. This high-precision analysis of spatio-temporal muscle dynamics wouldgive some new insight into muscle mechanics.
