What are the three main movements of the shoulder joint?

The three main movements of the shoulder joint include abduction, adduction, and rotation.

Abduction refers to the movement of the arm away from the body, which is critical for lifting and raising the arms. Adduction is the opposite movement, bringing the arm closer to the body, essential for actions like lowering the arms down to the sides. Rotation encompasses both internal and external rotation of the shoulder, allowing the arm to turn towards or away from the body.

These movements are fundamental to a wide range of activities, from everyday tasks to more complex motions in sports and exercise. Understanding these key movements aids in both assessing shoulder function and developing targeted rehabilitation or strength training programs.
