The purpose of this study was to investigate if spinal height increases using 3-dimensional (3-D) spinal position with and without manual distraction load and to assess the correlation between spine height changes and degrees of trunk rotation.
Fifty-six participants were randomly placed in one of two groups: (1) 3-D spinal position with manual distraction load, and (2) without manual distraction load. Spinal height was measured before and after the interventions using a stadiometer. For the statistical analysis, we used a 2 (Loading status: pre- versus post-intervention height) X 2 (3-D spinal position: with versus without manual distraction load) repeated measures Analysis of Variance (ANOVA) was used to identify significant interaction and main effects. Paired t-tests were used to calculate differences in spinal height changes between the two interventions. Pearson correlation coefficient was used to measure correlations between changes in spinal heights and degrees of trunk rotation.
Mean spinal height increase with 3-D spinal position with and without manual distraction load was 6.30 mm (±6.22) and 5.69 mm (±4.13), respectively. No significant interaction effect was present between loading status and 3-D spinal position but a significant main effect in loading status was. Paired t-tests revealed significant differences in spinal heights between pre-and post-3-D spinal position with and without manual distraction load. No significant correlation was measured between trunk rotation and spinal height changes.
3-D spinal position with or without distraction load increased spinal height. This suggests that 3-D spinal positioning without manual distraction could be used in home settings to help maintain intervertebral disc (IVD) health.
本研究旨在探讨在使用三维（3-D）脊柱定位并施加手动分离负荷和不施加手动分离负荷两种情况下，脊柱高度是否增加，并评估脊柱高度变化与躯干旋转程度之间的相关性。
56 名参与者被随机分为两组：（1）使用三维脊柱定位并施加手动分离负荷，（2）不施加手动分离负荷。使用测高仪在干预前后测量脊柱高度。对于统计分析，我们使用 2（加载状态：干预前后的高度）×2（3-D 脊柱位置：有手动分离负荷与无手动分离负荷）重复测量方差分析（ANOVA）来确定显著的交互和主要效应。使用配对 t 检验计算两种干预措施之间脊柱高度变化的差异。使用皮尔逊相关系数来衡量脊柱高度变化与躯干旋转程度之间的相关性。
使用三维脊柱定位并施加和不施加手动分离负荷时，脊柱高度的平均增加量分别为 6.30 毫米（±6.22）和 5.69 毫米（±4.13）。加载状态和 3-D 脊柱位置之间没有显著的交互效应，但加载状态有显著的主要效应。配对 t 检验显示，在施加和不施加手动分离负荷的情况下，三维脊柱定位前后的脊柱高度有显著差异。躯干旋转与脊柱高度变化之间没有显著的相关性。
使用三维脊柱定位并施加或不施加分离负荷可增加脊柱高度。这表明，在家庭环境中，可以使用不施加手动分离负荷的三维脊柱定位来帮助维持椎间盘（IVD）健康。
