摘要：Objectives: This study investigated changes in craniocervical and trunk flexion angles and gluteal pressure on both sides during visual display terminal (VDT) work with continuous cross-legged sitting. Methods: The gluteal pressures of ten VDT workers, who were recruited from laboratories, were measured using a Teckscan system and videotaped using a single video camera to capture the craniocervical and trunk flexion angles during VDT work at 30 s, 10, 20 and 30 min. Results: The craniocervical angle was significantly increased at 10 and 20 min compared with the initial angle ( p <0.05). The trunk flexion angle was significantly decreased at 30 s, 10, 20 and 30 min ( p <0.05). The gluteal pressure of the crossed-leg side significantly increased at 30 s, 10 and 20 min ( p <0.05). The gluteal pressure of the uncrossed-leg side significantly decreased at 30 s ( p <0.05). Conclusion: We found that cross-legged sitting during VDT work may exert disadvantageous postural effects resulting from craniocervical and trunk flexion angles and gluteal pressure. Therefore, this posture could not be recommended during long-term VDT work.
