Abstract

[Purpose] We investigated whether ultrasonography can detect changes in the right and left sternocleidomastoid (SCM) and longus colli (LC) muscles between different loads in the craniocervical flexion test. [Subjects and Methods] The subjects were 12 male and 12 female healthy adults. Still images of the subjects at rest, and at 5 different loads in the craniocervical flexion test, were captured by ultrasonography. The thicknesses of SCM and LC, and the cross-sectional area of LC were measured on the images. [Results] The cross-sectional area of LC on the non-dominant side showed a large value compared with that on the dominant side. In the craniocervical flexion test, the cross-sectional areas of both the right and left LC showed significant increases at loads greater than the intermediate level. [Conclusion] Changes in LC muscle activity can be verified on ultrasonography images, suggesting its usefulness as a test feedback method.
