Table 1 Summarized description of the job rotation definition

From: The effectiveness of job rotation to prevent work-related musculoskeletal disorders: protocol of a cluster randomized clinical trial

Step Definition Description
1 Ergonomic work analysis Evaluate the main demand of work posture adopted in the task, movements per body region (amplitude and frequency), autonomy, work rate, percentage of occupation in work cycles
2 Ergonomic exposure risk level assessment Classify the activity exposure level ergonomic (low, moderate, high and very high) by two observational protocols: Quick Exposure Check (QEC) and Rapid Entire Body Assessment (REBA)
3 Job rotation definition Propose the structure of job rotation in accordance with the following priority criteria: (1) the level of exposure intensity (low, moderate, high or very high), (2) predominantly stance taken by the completion task (sitting, kneeling, standing, walking), (3) the main physical demand (material handling, repetition of movements, static posture), (4) body regions of higher overhead (shoulders, elbows, wrists, hands, spine), (5) production’s specificities
