METHODS: In this retrospective study, we included women aged ≥ 65 years who were attending the outpatient clinic for osteoporosis at our hospital. A total of 287 patients (mean age ± SD, 76.8 ± 7.1 years) with measured SAD were included in the analysis. Patients were divided into two groups based on SAD cutoff (160 mm) and age (75 years), respectively. The patients were examined using the two-foot 20 cm rise test, 3 m Timed Up and Go (TUG) test, two-step test, open-eyed one-leg standing time, and spinal alignment. Normally distributed data are expressed as means (standard deviations) and non-normally distributed data as medians (interquartile range), depending on the results of the Kolmogorov-Smirnov test. Student\'s t-test and χ2 test were used for between-group comparisons. Regression analysis was performed with SAD as the objective variable. A two-sided p < 0.05 was considered statistically significant.
RESULTS: The shorter SAD group performed better in the two-step test, TUG test, and open-eyed one-leg standing time (p < 0.001) as well as in the two-foot 20 cm rise test (p < 0.01) compared to the longer SAD group. Spinal alignment was better in the shorter SAD group than in the longer SAD group, with a shorter sagittal vertical axis (p < 0.001), smaller pelvic tilt (p < 0.001), and greater sacral slope (p < 0.05).
CONCLUSIONS: SAD was associated with posterior pelvic tilt and movement performance parameters. In addition to testing for osteoporosis, movement performance parameters should be evaluated in women with osteoporosis who are aged ≥ 65 and have greater SAD (≥ 160 mm in this study). The SAD is a new assessment method, and further research is required to verify its validity and reproducibility. This is the first attempt to determine how age and SAD affect movement performance in older adults.
方法:在这项回顾性研究中,我们纳入了年龄≥65岁的女性,她们在我院接受骨质疏松症门诊就诊.共287例患者(平均年龄±SD,76.8±7.1年),测量的SAD包括在分析中。根据SAD截止值(160mm)和年龄(75岁)将患者分为两组,分别。使用两英尺20厘米上升测试对患者进行检查,3m定时上行(TUG)测试,两步测试,睁眼单腿站立时间,和脊柱对齐。正态分布数据表示为均值(标准差),非正态分布数据表示为中位数(四分位数范围),取决于Kolmogorov-Smirnov测试的结果.组间比较采用学生t检验和χ2检验。以SAD为客观变量进行回归分析。双侧p<0.05被认为是统计学上显著的。
结果:较短的SAD组在两步测试中表现更好,TUG试验,与较长的SAD组相比,睁眼单腿站立时间(p<0.001)以及两英尺20cm上升测试(p<0.01)。较短的SAD组的脊柱对准优于较长的SAD组,矢状垂直轴较短(p<0.001),骨盆倾斜较小(p<0.001),和更大的骶骨斜率(p<0.05)。
结论:SAD与骨盆后倾斜和运动性能参数相关。除了检测骨质疏松,对于年龄≥65岁且SAD较大(本研究≥160mm)的骨质疏松症女性,应评估其运动性能参数.SAD是一种新的评估方法,需要进一步的研究来验证其有效性和可重复性。这是首次尝试确定年龄和SAD如何影响老年人的运动表现。
