Impaired mobility is probably the most common reason why patients are exposed to the prolonged uninterrupted pressure that causes pressure injuries. This situation may be present in patients who are neurologically impaired, heavily sedated or anesthetized, restrained, demented, or recovering from a traumatic injury. These patients cannot alter their position far enough or often enough to relieve the pressure. Prolonged immobility may lead to muscle and soft tissue atrophy, decreasing the bulk over which bony prominences are supported.
