- Select appropriate tasks to evaluate based on injury/complaint history, high-force demands, or awkward postures. Avoid assessing rare or insignificant tasks.
- Determine the optimal time to perform the REBA to observe “typical” exposures, not anomalies. Capture peak volumes, cadences, and fatigue.
- Involve experienced, trained assessors. Use multiple observers if possible and compare scores. Review criteria and practice scoring common postures as a team to improve consistency.
- Explain the purpose of the REBA to workers so they understand the importance and allow photos to be taken. Address any concerns about how results will be used.
- Use REBA as a screening-level tool to complement more in-depth assessments when warranted. REBA alone may not provide sufficient data for complex or highly dynamic tasks.
- Carefully interpret REBA scores in light of variability, combining it with input from workers, engineers, medical staff, and data analysis experts.
- Focus on the overall risk reduction strategy, not just generating a number. The REBA should guide an effective control plan, not just quantify risks.
With proper training, application, and interpretation, the REBA methodology can offer immense value in systematically assessing and controlling ergonomic risks. Being aware of its limitations allows you to maximize its utility within a comprehensive ergonomics program.
Therefore, I recommend primarily using REBA as an early indicator for MSD injuries and then taking proactive measures based on the results of the assessments.
