Ergonomics Awareness Training for Supervisors Practice Test

What is the impact of repetitive motions on workers' health?

1. It can decrease productivity

2. It leads to improved muscle strength

3. It has no impact

4. It can cause musculoskeletal disorders

The correct answer is: It can cause musculoskeletal disorders

Repetitive motions can significantly impact workers' health by leading to musculoskeletal disorders (MSDs). These are injuries related to the muscles, tendons, ligaments, and nerves, which can develop over time as a result of performing the same motion repetitively. The lack of variation in movement can cause fatigue in the muscles and joints, leading to strain and injury. Common examples of MSDs include carpal tunnel syndrome, tendonitis, and strain injuries, which can result in pain, discomfort, and a decrease in an individual's ability to perform their job efficiently. Furthermore, these disorders not only affect workers' physical health but can also have psychological effects, such as increased stress or job dissatisfaction due to chronic pain. Understanding the impacts of repetitive motions underscores the importance of ergonomic practices in the workplace, where modifications to tasks, tools, and ergonomics can help minimize these risks, improve worker safety, and sustain productivity in the long term. Engaging in job rotation, varying tasks, and incorporating adequate breaks can be effective strategies in mitigating the adverse health effects associated with repetitive motions.
