Which is an eccentric function of the trapezius?

Question

Quizplus · Accepted Answer

The trapezius muscle is responsible for multiple movements and functions including elevation, depression, and upward rotation of the scapula, as well as extension and lateral flexion of the neck. However, the eccentric function of the trapezius is to restrain or slow down retraction (adduction) of the scapula at the scapulocostal joint. This is because the trapezius is often overactive and hypertonic, leading to difficulty in isolating other muscles of the shoulder girdle. By focusing on the eccentric control of scapular adduction, the trapezius can be trained to work with other muscles of the shoulder for improved movement and function.
