Abstract

Maintaining a neutral pelvic position and balanced center of gravity is essential for promoting spinal health in college students. This study examines how pelvic neutral displacement impacts scoliosis progression, based on the mediating effect of center of gravity movement. Method: (1)A cross-sectional study was conducted with 506 randomly selected college students (294 females, 212 males; age 21.73 ± 2.74 years). Measurement indicators included the Angle of Trunk Rotation (ATR), pelvic rotation angle, pelvic tilt angle, and center of gravity movements within 10 seconds. (2) Multivariate linear regression analysis examined correlations between pelvic rotation, pelvic tilt, center of gravity movement, and scoliosis characteristics (type, region, and direction). (3)A structural equation model was used to assess how pelvic neutral displacement and center of gravity movement interact in scoliosis progression. (4)Based on the above, the importance of center of gravity balance and pelvic neutrality for spinal health was validated. The scoliosis detection rate was 18.5%, with lumbar scoliosis accounting for 49.2%. Scoliosis with ATR > 5° showed a positive correlation with pelvic rotation (r = 0.304, P < 0.01). Lumbar scoliosis was linked to pelvic tilt and center of gravity movement. Pelvic tilt directly influenced ATR (e = 0.2344) and indirectly affected ATR via center of gravity movement (e = 0.1002), with the strongest effect observed in right-sided lumbar scoliosis. College students with ATR > 5° scoliosis exhibit increased pelvic rotation and center of gravity movement, leading to reduced balance ability. Pelvic tilt influences lumbar scoliosis via center of gravity movement. Neutral pelvic position should be fully considered in the treatment of lumbar scoliosis patients to enhance symmetrical pelvic mobility and stabilize the center of gravity.
