Title: Body pressure distributions of the varying sitting postures in office work
Abstract: Objective: The aim of this study is to find the ratio of right sitting posture in office workers’ daily job. Background: Although office workers know the right sitting posture, their postures observed are likely to be biased improperly. These behaviors are caused by bad design of chair or by task variables. To find the problem of bad postures, a body pressure mat can be used. Method: Three office workers’ seat and back pressure during daily work were measured by using two 36 x 36 pressure mats. Then the average pressure of right/left and posterior/anterior area and back pressure were used to categorizing good and bad postures. Results: Office workers pose properly in only 3.2% of daily work. Most of time, 81.5%, their back were separated from seat back. Also they bent and twisted their back improperly to perform tasks. Conclusion: The result showed that office works pose improperly during work. To maintain the proper posture, ergonomic design in seat pressure is needed. Application: The evaluation method used in this study can be applied to evaluate chairs.
