Which of the following practices helps prevent repetitive motion injuries?

Sitting or standing as straight as possible is an important practice for preventing repetitive motion injuries because maintaining proper posture reduces strain on muscles and joints. Good posture helps to align the body properly, minimizing the wear and tear on the musculoskeletal system. When you maintain a neutral spine position, you can distribute physical stress more evenly across the body, which decreases the likelihood of overuse injuries that often occur from repeated motions, such as typing or using machinery.

In contrast, other practices such as taking short breaks every hour are also beneficial for preventing injuries but do not specifically address the importance of posture. Using the same motion repeatedly is clearly counterproductive in injury prevention. Meanwhile, positioning equipment at eye level can aid in reducing strain during tasks, but without proper posture, the body may still be subjected to unnecessary stress. Overall, while several practices contribute to injury prevention, emphasizing correct posture is fundamental for long-term musculoskeletal health and comfort.
