What does the term rotation refer to in joint movement?

The term rotation in joint movement specifically describes the action of turning or spinning a body part around its own axis. This can occur in various joints of the body, such as the shoulder or hip, where the bone moves in a circular manner around a fixed point.

When a joint rotates, it allows for movements such as turning the head from side to side or the internal and external rotation of limbs. This makes rotation crucial for a variety of physical activities, including sports and exercises, where efficient movement patterns around an axis are needed for performance and injury prevention.

Understanding rotation helps in assessing joint function and mechanics, especially in rehabilitative settings where restoring normal movement patterns is vital for recovery.
