Changes in gluteal pressure and pelvic inclination angles after continuous cross-legged sitting

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.
