Value of the ERGOS work simulator as a component of functional capacity assessment in disability evaluation

Abstract

The use of assessment instruments in evaluating functional capacity is an important element in the process of social-medical judgement of whether a person will likely be able to reintegrate into working life. Standardized work processes are used in simulating occupational reality over several hours, with all the requirements involved, and the performance found is contrasted with the requirements to be expected at a workplace. Time-tested in the U.S. for more than 20 years and applied throughout Germany for some two years now, the ERGOS work simulation system is presented in the article, using a case example for more detailed description. Using five different work stations, performance data are collected for job tasks such as carrying, working in kneeling position or overhead, and subjected to computer-based comparison with the job requirements information contained in relevant databases. This enables computerized identification of excessive demands, and hence may point to a need for further rehabilitative action. An important feature is objective assessment, as subjective information on the basis of observation or reports of painfulness are raised separately, hence do not influence the findings of the work simulation performed.
