[Purpose] The purpose of this study was to show the changes in the center of force in gluteal region and pelvic tilt angle after continuous visual display terminal work. [Subjects] Ten male computer workers were recruited. [Methods] The subjects performed computer work for 1 hour, and the pelvic tilt angles before and after the 1 hour of work were measured using a palpation meter. A Body Pressure Measurement Mat of a TekScan system was used to measure the center of force at the gluteal region seat interface of the chair before and after 1 hour of computer work. [Results] The results showed that the left and right posterior pelvic tilt angles were significantly increased after work. The distance to the center of force in the gluteal region also showed significantly posterior movement. [Conclusion] These results indicate that continuous computer work may cause structural changes of the spine and pelvis.
