Electromyographic study of levator scapulae and rhomboideus major muscles in movements of the shoulder and arm

In 21 normal adult male subjects, the muscular activity of the levator scapulae and rhomboideus major muscles was studied electromyographically during the movements of the shoulder and arm. Two single coaxial needle electrodes were used for registering the action potentials. Concerning shoulder movement, it was shown that the levator scapulae was active in elevation and rhomboideus major was active in retraction. Both muscles were inactive during protrusion, in most events. Concerning free movements of the arm, both muscles were active in abduction, elevation, adduction, flexion and circumduction, but inactive in extension. During the same movements, performed with a load, we observed greater intensity in the activity of these muscles in comparison to their activity during free movements.
