RULA proved to be, in general, a suitable
method for evaluating student’s posture. A
relationship was seen between increasing Action
Level and increasing frequency of reported
discomfort in the back/neck area and the shoulders.
An increase in average discomfort score was seen
from Action Level 2 to Action Level 3 but this
relationship was not observed from Action Level 3 to
Action Level 4. This finding is limited due to the
small number in Action Level 4. Further
investigation is required with a larger population.
