Preventive health care is one of the basic challenges facing ergonomics. The aim to prevent occupationally generated musculoskeletal disorders and diseases may be achieved by appropriate workplace and product design. ERGOMan is a computer-aided 3D man model suitable for ergonomic and movement simulation at industrial workstations. Within a common project of the above mentioned institutions ERGOMan's inventory of ergonomics design tools shall be enhanced in a way that ERGOMan will be able to give detailed information on load or stress situations, which might effect the executability and tolerability of work situations with high probability. © 1997 John Wiley & Sons, Inc.
