Figure 3

The ultrasound image shows the three range of interest (ROI) manually placed in the first frame of the video sequence of each muscle in longitudinal projection. The superficial sternocleidomastoid (A) shown at the top, followed by the common carotid artery (B), longus capitis (C) and longus colli (D). The ROI measuring the deformation (elongation and shortening) and the deformation rate (how fast the shortening and elongation occurs). Each ROI are indicated as a blue line with a square at each end.
