What does shearing refer to in the context of tissue integrity?

Shearing refers to the force exerted against the skin by movement, particularly when the skin remains in place while the underlying tissues shift or slide. This occurs in situations such as when a patient is moved or repositioned in bed, where the skin may stick to the surface of the bed while the bones and other tissues underneath continue to move. This type of force can cause damage to the blood vessels and connective tissues, leading to tissue injury and increasing the risk of pressure ulcers or sores.

In context, shearing is particularly important to understand for maintaining tissue integrity, as it directly relates to how movement affects the skin and underlying structures. Identifying and managing shearing forces is essential in preventive care, especially for individuals with limited mobility.
