What is the main use of leg restraints in correctional situations?

In correctional situations, leg restraints are primarily used to limit the movement of a subject. This is crucial for maintaining safety and security in corrections environments. Restraining a subject's legs helps to prevent potential escape attempts, as well as minimizes the risk of injury to the individual, staff, and other inmates during transport or when managing volatile situations. By confining the subject's movement, correctional officers can exert greater control, ensuring that the individual remains compliant and does not pose a risk of harm to themselves or others.

The other options do not reflect the primary purpose of leg restraints. Enhancing mobility or providing comfort are not goals achieved through the application of restraints; instead, they are designed specifically to restrict movement for the reasons mentioned. Similarly, while assistance during walking may be a minor consideration in some contexts, the primary function of leg restraints is to ensure control and manage behavior safely.
