Retraction
Scapular Retraction (Scapular Adduction): A joint action of the scapula (shoulder blade) that is movement toward the spine and the back of the body, following the curvature of the ribcage. This motion also causes the glenohumeral joints (shoulders) to move posteriorly. This joint action is sometimes referred to as "scapular adduction" because the scapula moves toward the midline of the body.
- Opposing Joint Action: Scapular Protraction
- Plane of Motion: Transverse
- Direction Bias: Medially and posteriorly
- Note: Joint actions may be referred to as "osteokinematic motions" or "osteokinematic joint actions" to differentiate them from "arthrokinematic motions " (e.g., spin, glide, roll, compression, and distraction).

Joints that Perform Scapular Protraction (and Sample Exercises):
- Scapulothoracic Joint (Shoulder Girdle): Scapula retraction occurs around a vertical axis in a medial and posterior motion around the rib cage. This action may be observed during during rows , including suspension rows , and rope rows .
