Range of Motion: What Determines How Far a Joint Moves

Definition

Range of motion

The range of motion (ROM) refers to how far the bones of a joint can move relative to each other.

Several Factors Influence a Joint's Range of Motion

Joint structure
1. Hinge joints, such as the elbow and knee, move in one plane: flexion and extension.
2. Ball-and-socket joints, such as the hip and shoulder, move in many planes and have the greatest range of motion.
Ligaments and the joint capsule
1. Ligaments are strong fibrous tissues that connect bones and limit excessive movement.
2. The joint capsule surrounds the joint, adding stability and restricting motion.
Muscles and tendons
1. Muscles generate force and tendons connect muscle to bone.
2. The flexibility of these tissues strongly affects range of motion.
3. Regular stretching can lengthen muscles and tendons, improving mobility over time.
