Which item below is a principle of good body mechanics?

Keeping the natural curve of the spine when lifting is a fundamental principle of good body mechanics. This practice helps to maintain proper alignment and reduces the risk of back injury. The natural curve of the spine supports weight distribution more effectively and allows for better balance and control while lifting objects. It ensures that the muscles used in lifting are engaged properly, minimizing strain on the back and promoting safer lifting techniques.

In contrast, bending from the waist, reaching into deep tubs and bins, or twisting sharply at the waist can lead to poor body mechanics. These actions can put undue stress on the spine, potentially causing injuries or discomfort. Proper lifting techniques are crucial for those in caregiving roles, such as direct support professionals, to ensure both their safety and the safety of those they are assisting.
