Abstract: Objective: The objective of this study was to determine the changes
in left and right gluteal pressures and posterior inclination angles between
the anterior superior iliac spine (ASIS) and posterior superior iliac spine
(PSIS) on both sides after continuous cross-legged sitting. Methods and participants: Fourteen young adults (nine males and five females) were
recruited. The statistical significance of differences in parameters between
before and after continuous cross-legged sitting was tested by paired
t-tests. Results: After sitting in a right-crossed-leg position for
10 minutes and then returning to a upright sitting posture, the subjects' right
gluteal pressure increased significantly compared to before cross-legged
sitting (p< 0.05). After sitting in a right-crossed-leg position and then
returning to an upright standing posture, the posterior inclination between the
right ASIS and PSIS increased significantly compared to before cross-legged
sitting (p< 0.05). Conclusion: These results indicate that
continuous cross-legged sitting may cause malalignment of the pelvis after the
cross-legged sitting period.
