This information was re-collected after a four-month ergonomic audio-visual training course. Then, by using the paired t-test, the effectiveness of this training course was evaluated.


Data indicated that almost half of the workers were in the worst possible posture; The number of people in this group did not change before and after the training, also two thirds of the samples had a moderate productivity score that training couldn’t change number of this group too. However, despite the lack of significant changes in the categories of exposure to risk factors of ergonomics and productivity, the changes in scores within these two groups were significant. It means that this was not significant in the way that the levels of these two variables in the studied samples Change.
