Bed mobility refers to an individual’s ability to move or reposition their body while lying in a bed or similar sleep surface. This includes changing positions, adjusting the body, or moving to a sitting position. Maintaining this ability is a fundamental part of functional independence and is recognized as one of the essential Activities of Daily Living (ADLs) that contribute to overall health and comfort.
Essential Actions of Bed Mobility
Bed mobility involves specific, fundamental movements that allow for functional independence within the bed space. The first category is repositioning, which includes movements like “scooting” the body up, down, or side-to-side on the mattress. This action often relies on the “bridging” movement, where the individual lifts their hips off the bed by pushing down with their feet and elbows, allowing for small, controlled shifts of the lower body.
The second core action is turning or rolling, which involves moving from a supine (back-lying) position to a side-lying position. This is typically accomplished by bending the leg opposite the direction of the roll and reaching across the body with the opposite arm, effectively using momentum and leverage. Rolling is a necessary movement for performing self-care tasks and preparing for transfers out of bed.
The third and most complex action is transitioning, specifically moving from a lying position to sitting up at the edge of the bed. This maneuver, often called a supine-to-sit transfer, requires using the arms to push the torso upright while simultaneously swinging the legs off the side of the mattress. Mastering this allows a person to adjust their position for comfort and prepare to stand or transfer to a chair.
Clinical Importance of Maintaining Bed Mobility
Maintaining the capacity for unassisted or assisted bed mobility is directly linked to the prevention of serious health complications. The most recognized benefit is the prevention of pressure injuries, commonly known as bedsores or pressure ulcers. These injuries develop when sustained pressure on bony prominences, such as the sacrum, heels, or hips, restricts blood flow to the skin and underlying tissue, leading to tissue damage.
Repositioning, which should ideally occur at least every two hours for individuals with severely limited mobility, redistributes pressure and allows blood to flow back into compressed areas. Preventing these injuries is a primary concern because pressure ulcers can lead to severe infections and prolong recovery times. Regular movement in bed also promotes better respiratory and circulatory health.
Changing body positions helps prevent the pooling of fluid in the lungs, which can lead to conditions like pneumonia, especially during prolonged bed rest. Movement also encourages venous return, helping to prevent the formation of blood clots like deep vein thrombosis (DVT). The ability to move stimulates circulation and supports overall tissue oxygenation.
Equipment and Assistance Techniques
When a person’s physical ability to perform bed mobility is compromised, various tools and specific techniques are employed to provide assistance. Assistive devices like bed rails or trapeze bars provide a stable handhold, allowing an individual to use their upper body strength to pull themselves up or roll over. These devices offer leverage that can significantly reduce the physical effort required for repositioning, promoting greater independence.
Specialized equipment, such as friction-reducing slide sheets or transfer sheets, are utilized by caregivers to move individuals with minimal effort and reduce the risk of injury to both the patient and the helper. These sheets are made from low-friction material, allowing a person to be slid across the mattress rather than lifted, which minimizes harmful shear and friction forces on the skin. Caregivers must also employ proper body mechanics to ensure safety during assisted movements.
Techniques such as maintaining a straight back, bending the knees, and keeping the person being moved close to the body reduce the risk of musculoskeletal injury to the caregiver. Clear verbal cues also help the person being assisted to engage their muscles and participate in the movement. This combined approach ensures that necessary repositioning can be performed safely and effectively.
