Body Mechanics and Safe Client Transfers

Principles of Ergonomics and Health Care Worker Safety

Practicing sound body mechanics protects health care workers from disabling physical injuries while ensuring client security during movement. Adhering to ergonomic safe client handling policies minimizes occupational musculoskeletal injuries among nursing staff. The foundation of safe movement begins with establishing balance. A wide base of support provides stability by placing the feet shoulder-width apart. The nurse maintains balance by keeping the center of gravity low and within this base of support. When preparing to lift an item or provide bedside care, bending at the knees and hips rather than at the waist significantly reduces strain on the lumbar spine.

How a nurse handles physical forces directly influences the risk of injury. For light loads that can be handled manually, the nurse must use the strong muscles of the legs and hips rather than relying on the back. However, manual lifting of clients must be avoided; the nurse must use approved equipment instead of manually lifting clients. Pushing or using friction-reducing aids generally requires less physical effort than lifting. When carrying light items manually, the nurse keeps loads close to the body, but safe-handling equipment must always be used rather than manually lifting clients.

Body alignment during movement is critical for preventing spinal trauma. Twisting the spine while lifting or moving a client significantly increases the risk of back injury. To change direction while moving a client, the nurse pivots on the feet instead of twisting the torso. Working height must also be adjusted thoughtfully throughout the shift. The nurse raises the bed to a comfortable working height for bed care to avoid excessive bending, and then lowers it to a safe height for transfers. Once care is completed, lowering the bed to its lowest position and locking the wheels ensures client safety.
