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).
