Pivot joint in rotating an arm inward). When rotating the forearm, these movements are typically called pronation and supination. In the standard anatomical position, the forearms are supinated, which means that the palms are facing forward, and the thumbs are pointing away from the body. In contrast, a forearm in pronation would have the palm facing backward and the thumb would be closer to the body, pointing medially. Examples of a pivot joint include: In contrast, spherical joints (or ball and socket joints) such as the hip joint permit rotation and all other directional movement, while pivot joints only permit rotation.

Pivot turn basically maintained during the turning. The turn starts with the right foot raised from the floor. While continuously revolving, on each strong beat (downbeat) the right foot is stepped flat and on each weak beat (upbeat) the left foot is stepped on the ball (by the right heel). Various types of pivot turns are performed in ballroom dance, including slip pivot, reverse pivot, chains of pivot turns, half pivot (as in fourth step of a natural spin turn), man's first step of an outside spin, and man's third step (toe pivot) of a double reverse spin.
