What is meant by shearing force in relation to moving someone?

Shearing force refers to the force that is applied when one part of the body moves in one direction while an adjacent part moves in the opposite direction. In the context of moving someone, shearing force can result in skin friction and tissue damage if the person is dragged or moved in a way that causes opposing forces on different parts of their body. It is important to minimize shearing forces when moving someone to prevent injury.
