Effect of a suspension seat support chair on the trunk flexion angle and gluteal pressure during computer work

Purpose We assessed the effects of a suspension seat support chair on the trunk flexion angle and gluteal pressure during computer work. Subjects Ten males were recruited. Methods The suspension seat support was developed to prevent abnormal gluteal pressure and a slumped sitting posture during computer work. The gluteal pressure was measured with a TekScan system and the trunk flexion angle was measured with a video camera, to compare the differences between a general chair and the suspension seat support. Results The gluteal peak pressures were decreased significantly in the suspension seat support versus the general chair. The trunk flexion angle was also decreased significantly in the suspension seat support compared with the general chair. Conclusions This study suggests that the suspension seat support chair contributes to preventing abnormal gluteal pressure and a slumped sitting posture.
