Arm abduction
Arm abduction represents movement of the arm away from the midline of the body in the coronal plane and, in most cases isolated abduction can be achieved to 160-180°. It is the opposite of arm adduction and contributes to the combined movement of shoulder circumduction.
It is produced by:
- deltoid (middle fibers)
- supraspinatus
See also movements of the arm.
