What type of movement does a 'circular movement of a limb' correspond to?

Circumduction is the term that accurately describes the circular movement of a limb. This movement involves a combination of flexion, extension, abduction, and adduction, allowing the distal end of the limb to move in a circular path while the proximal end remains relatively stable.

For example, when you move your arm in a circular motion, like when waving, your shoulder performs circumduction. This distinctive movement is common in joints that allow a wide range of motion, such as the shoulder and hip. Understanding circumduction is important in orthotic fitting as it pertains to recognizing how different devices may interact with or restrict movement in the joints.

In contrast, abduction and adduction refer specifically to movements away from or toward the midline of the body, and weight-bearing relates to the ability to support body weight through particular limbs or structures, rather than describing a circular motion. Thus, circumduction is the correct choice as it specifically captures the nature of the described movement.
