The influence of job rotation and task order on muscle responses in females
Job rotation aims to reduce muscle fatigue by switching between functionally different tasks to theoretically lessen the risk of site-specific fatigue and work-related musculoskeletal disorders (WMSDs). The effectiveness of job rotation in mitigating the onset of muscle fatigue is partially known, but there is limited ergonomic data on female populations despite comparatively lower upper body strength and increased risk of WMSDs. Rotating between two functionally different tasks, continuing a single task, and varying task order were assessed in the present study for influence on muscle fatigue...
Visual and psychological stress during computer work in healthy, young females - physiological responses
Purpose: Among computer workers, visual complaints, and neck pain are highly prevalent.
