How do you do Circumduction?

Circumduction is the movement of the limb, hand, or fingers in a circular pattern, using the sequential combination of flexion, adduction, extension, and abduction motions. Adduction/abduction and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.

Which joint is capable of Circumduction?

Ball and socket joints (e.g., the hip joint ) are capable of circumduction (circular motion). Limbs as a whole are capable of rotation (supination/pronation) and movement away from (abduction) and toward (adduction) the body.
