Photograph-based ergonomic evaluations using the Rapid Office Strain Assessment (ROSA)
We examined the use of photographs to perform ROSA evaluations of office workstations. Photo assessment interrater reliability ranged from fairly good to excellent, and was comparable to previous results. Photo-assessments had more false-positives, which could lead to unnecessary additional ergonomic interventions. Sources of error include the parallax effect, and boundary errors in postural binning.
