Glenohumeral

Flexion

Bending the joint resulting in a decrease of angle; moving the upper arm upward to the front.
Shoulder Flexion

Extension

Straightening the joint resulting in an increase of angle; moving the upper arm down to the rear.
Shoulder Extension

Adduction

Medial movement toward the midline of the body; moving the upper arm down to the side toward the body.
Shoulder Adduction

Abduction

Lateral movement away from the midline of the body; moving the upper arm up to the side away from the body.
Shoulder Abduction

Transverse Adduction

Medial movement toward the midline of the body in a horizontal plane; moving the upper arm toward and across the chest with the back of the arm facing down.
Shoulder Transverse Adduction

Transverse Flexion

Medial movement toward the midline of the body in a horizontal plane; moving the upper arm toward and across the chest with the elbows facing out to the sides.
Shoulder Transverse Flexion

Transverse Abduction

Lateral movement away from the midline of the body in a horizontal plane; moving the upper arm away from the chest with the elbows facing down.
 Transverse Abduction Shoulder

Transverse Extension

Lateral movement away from the midline of the body in a horizontal plane; moving the upper arm away from the chest with the elbows out to the sides.
Shoulder Transverse Extension

Medial Rotation (Internal Rotation)

Rotary movement around the longitudinal axis of the bone toward the center of the body; turning the upper arm inward. See shoulder internal rotation inflexibility.

*When shoulder is flexed (Ackland DC, Pandy MG, 2011).

Medial Rotation (Internal Rotation)

Lateral Rotation (External Rotation)

Rotary movement around the longitudinal axis of the bone away from the center of the body; turning the upper arm outward. See shoulder external rotation inflexibility.

*When shoulder is abducted (Ackland DC, Pandy MG, 2011).
