Computer based observational technoques for assessing exposure to risk factors for workrelated musculoskeletal disorders: A review

The aimed of this review is to make an overview of the current techniques for computer based observational methods in assessing Work-related Musculoskeletal Disorders (WMSDs).Articles related to computer based observational method for assessing WMSDs are searched and collected from scientific database starting from 1977 to 2016. Seven methods are identified for computer based observational techniques and from these methods, only three methods have been evaluated as the intra-observer reliability and five methods are evaluated as inter-observer reliability where the average results are moderate to good agreement. For concurrent validity, five methods have been evaluated with moderate agreement.There is no method for computer based observational techniques which cover all of the risk factors of WMSDs. In addition, these current techniques did not fulfil the criteria of reliability and validity testing during the development of these methods
