Summary: Musculoskeletal disorder risk was examined during the current assembly processes compared to that using a cantilever chair intervention tool. The results indicate in which regions of the vehicle the cantilever chair intervention tool was most effective at reducing the risk of low back and shoulder disorders. The cantilever chair was a good intervention in the front far reach region regardless of height, because it reduced spine loads and reduced normalized shoulder muscle activity. In the middle and close reach distance regions the cantilever chair caused spine loads to be reduced however other interventions would be necessary to reduce normalize shoulder muscle activity. In the back region of the vehicle the cantilever chair caused no change in spine loads and increased shoulder muscle activity, therefore it was not an effective intervention tool in this region.
