Which factors can contribute to back injury?

Back injuries can often be attributed to several risk factors, and the selection of poor posture, tension, stress, and accidents captures the essence of common contributors to these injuries. Poor posture is significant because it places undue strain on the spine and surrounding muscles over time, potentially leading to chronic pain or injury. Tension and stress can exacerbate muscle tightness, which may further compromise spinal integrity and flexibility. Accidents, whether they are slips, falls, or improper lifting techniques, can directly cause back injuries by leading to sudden strains or trauma to the back.

In contrast, while regular exercise and good posture, as well as using proper lifting techniques and maintaining a healthy weight, are all vital components of back health and injury prevention, they do not represent contributing factors in the context of causing back injuries. Instead, they are preventive measures that help reduce the risk of injury. Recognizing the factors that contribute to injuries, such as those listed in the correct answer, is essential for understanding how to improve workplace safety and personal health practices.
