WERA Instructions and Worksheet

The Workplace Ergonomic Risk Assessment  (WERA) method has been developed by Mohd Nasrull Abd Rahman (from UTHM, Malaysia and currently a Ph.D student from UTM, Malaysia) with Prof Dr Mat Rebi Abdul Rani and Jafri Mohd Rohani (from UTM, Malaysia) .

 The WERA covers an extensive range of physical risk factors including posture, repetition, forceful, vibration, contact stress and task duration and it involved the five main body regions to be assessed (shoulder, wrists, back, neck and legs). It has a scoring system and action levels which provide a guide to the level of risk and need for action to conduct more detailed assessments. The WERA has been tested on its psychometric properties including reliability and validity trials during the development process.

A full description of the WERA method is contained in the original journal article: (Accepted & In-press) Rahman, M.N.A., Rani, M.R.A., and Rohani, J.M. (2011) WERA: An observational tool develop to investigate the physical risk factors associated with WMSDs, Journal of Human Ergology, 40(2).
