Abstract: Manual tasks in many operational settings can force individuals in awkward postures that may cause human discomfort, musculoskeletal fatigue, and disorders. Designers often fail to reasonably take into account human capabilities and body postures. This study shared the designer to choose one of the available drafting tables which characterize of causing fewer work stresses. There were three evaluation methodologies implemented to differentiate between the two types of tables. Electromyogram (EMG) measure, subjective assessment and biomechanical technique were applied to demonstrate the importance of introducing the use of these tools in the design for human beings. Results of the study proved that adjustable table had less biomechanical and muscular stresses when compared to fixed surface table. Also, the adjustable table had more comfort ratings when compared to fixed surface table.
