Physiology

 

Concentric Functions:

  • Elevation, downward rotations & abduction (protraction) of the scapula

 

Eccentric Functions:

  • Decelerates head & neck flexion (bilaterally)

  • Decelerates scapular depression & upward rotation (unilaterally)

  • Decelerates lateral flexion of the cervical spine (unilaterally)

 

Isometric Function:

  • Dynamically stabilizes the cervical spine during functional movements
