ABSTRACT
A RULA assessment represents a moment in the work cycle and it is important to observe the postures being adopted whilst undertaking the tasks prior to selecting the posture(s) for assessment. Depending upon the type of study, selection may be made of the longest held posture or what appears to be the worst posture(s) adopted. In some instances, for example when the work cycle is long or the postures are varied it may be more appropriate to take an assessment at regular intervals. It will be evident that if assessments are taken at set intervals over the working period the proportion of time spent in the various postures can be evaluated.
