Movement of a body part toward the midline (axis) of the trunk.
Detail
Adduction is movement toward the axis of the trunk. Examples include lowering the arm to the side and lowering the leg back to anatomical position. At the shoulder, adduction draws the arm from the side-horizontal position to the side; this is described as a weak action that is assisted by the latissimus dorsi. Source attributes the movement terminology to Thompson (1989).
Key facts
- Adduction = movement toward the axis of the trunk.
- Examples: arm lowered to the side; leg returned to anatomical position.
- Shoulder adduction is a weak action assisted by the latissimus dorsi.
Connections
- abduction — the opposite movement (away from the midline).
- hip-adductors — muscles that produce hip adduction.
- latissimus-dorsi — assists arm adduction at the shoulder.

The hip adductors are the pectineus, adductor brevis, adductor longus, adductor magnus, and gracilis.Hip Joint Range of Motion
Hip flexion 90° (knee extended) to 120° (up to 135°, knee flexed); hyperextension 10–30°; adduction 30°; abduction 45°; medial rotation 30–45°; lateral rotation 45–60°.Latissimus Dorsi
A 2-joint back muscle; its strongest action is adduction (drawing the arm to the side from side-horizontal, rotating inward), with extension second.
