Evaluation of selected ergonomic assessment tools for use in providing job accommodation for people with inflammatory arthritis.

Inflammatory arthritis (IA) is a leading cause of work disability, especially for those with jobs involving repetitive, hand-intensive or manual work. Ergonomic interventions may mediate against job loss. Our objective was to identify desirable features of an ergonomic tool for use in providing job accommodation for people with IA, and to evaluate a selection of ergonomic and rehabilitation tools against these features. Eight desirable features were compared across 16 assessment tools. None of the tools met all the pre-determined features. Ergonomic assessment tools should incorporate objective assessment of risk factors together with subjective perceptions of symptom aggravation, and identify risk factors that may not currently be causing problems, but may increase risk of aggravation or injury in the future. To accommodate the needs of people with IA, the tool should allow for evaluation of risks and generation of solutions without a worksite visit in situations where the client does not want to disclose their illness. Finally, an assessment tool needs to be applicable to a wide range of worksites, easy to use, valid, and reliable. Against these criteria, it appears that there is a lack of appropriate ergonomic assessment tools for use in people with IA.
