What condition is primarily caused by repetitive movements?

1. Musculoskeletal disorders

2. Carpal tunnel syndrome

3. Chronic fatigue syndrome

4. Stress-related illnesses

The correct answer is: Carpal tunnel syndrome

The condition primarily caused by repetitive movements is carpal tunnel syndrome. This condition develops when repetitive hand movements lead to increased pressure on the median nerve that runs through the wrist. Over time, activities such as typing, using a mouse, or performing assembly line work can lead to symptoms like pain, numbness, and tingling in the fingers. Carpal tunnel syndrome is directly associated with the mechanical stress on the wrist and the repetitive nature of the tasks being performed. It represents a specific type of musculoskeletal disorder characterized by its connection to repetitive motion rather than trauma or degenerative diseases. Understanding this link helps emphasize the importance of ergonomics and proper techniques in the workplace to prevent the onset of such conditions. Musculoskeletal disorders encompass a broader range of issues that can arise from repetitive movements, but they can also include other non-repetitive mechanisms and causes. Chronic fatigue syndrome and stress-related illnesses are influenced more by psychological aspects and overall health, rather than specifically by repetitive movements.
