[Purpose] This study evaluated the efficacy of a newly designed chair, equipped with a Posture Sensing Composite Display Device (PSCD), for correcting poor trunk posture while performing computer work. [Subjects] We recruited 10 male workers who regularly used a computer for at least 8h per day. [Methods] Subjects performed computer work while sitting on the newly designed chair with or without the PSCD. Lumbopelvic kinematic data were recorded for 60 s following 10, 20, and 30 min of computer work using a three-dimensional motion analysis system. [Results] The newly designed chair equipped with the PSCD significantly reduced lumbar flexion, lateral bending, and rotation during computer work. [Conclusion] The PSCD may prevent work-related musculoskeletal disorders by enabling a worker to maintain an upright posture during computer work.
