Ergonomics is designed to help reduce disorders associated with:

Ergonomics focuses on designing work environments, tools, and tasks to fit the capabilities and limitations of the human body. It aims to optimize human performance while minimizing the risk of injuries, particularly musculoskeletal disorders. The practice of ergonomics addresses various factors that contribute to these disorders, including bad posture, overuse of muscles, and repeated physical tasks.

Bad posture can lead to chronic pain and strain on various parts of the body, particularly the back, neck, and shoulders. Ergonomic interventions often include assessments and modifications of workstation setups to promote proper posture.

Overuse of muscles is another significant concern, as repetitive motions can lead to fatigue and repetitive strain injuries. Ergonomics seeks to balance workloads and introduce breaks or changes in tasks to prevent overuse injuries.

Additionally, repeated physical tasks can create wear and tear on muscles and joints, leading to long-term damage. Ergonomics encourages job rotation, variation in tasks, and the use of ergonomic tools to mitigate these risks.

By addressing all these aspects, ergonomics is a comprehensive approach that effectively targets the various contributors to musculoskeletal disorders, making the answer that encompasses all of them the most accurate choice.
