Which of the following activities poses a risk for developing back disability?

Lifting heavy loads poses a significant risk for developing back disability due to the strain and stress it places on the spine and surrounding muscles. When individuals lift objects that are beyond their capacity or use improper lifting techniques, they can experience acute injuries such as muscle strains and herniated discs. This is especially true if the lifting involves twisting or bending, which can further exacerbate the risk of injury. Over time, frequent heavy lifting can lead to chronic back problems and disabilities, making it crucial to use safe lifting practices and ergonomic techniques to minimize risk. Ensuring proper body mechanics, using lifting aids, and maintaining good physical conditioning can help reduce the likelihood of back injuries associated with heavy lifting.
