بررسی تأثیر ایستادن روی شیب‌های مثبت و منفی 7/3 درجه بر زوایای افقی ساکروم و شیب ساکروم در زنان دارای هایپرلوردوزیس

 Background & Aims: One of the most important factors of development of mechanical lumbosacral anomalies and the resulting pain in human beings is mobility and body weight bearing. The purpose of this quasi experimental study was to investigate and compare the impacts of standing on different gradients on sacrum horizontal angle and sacrum gradient in women with hyperlordosis. Materials & Methods: The subjects were 12 females with hyperlordosis as well as healthy ones who voluntarily participated in the study. In order to measure sacrum gradient and horizontal angle in three gradients of 0˚, +3.7˚, and -3.7˚ lateral spinal radiography technique was used. The analysis of data was done using descriptive statistics and K-S test, ANOVA, and LSD following test at significance level of p≤ 0.05 using SPSS (v.18).Results: Statistical results implied ineffectiveness of the three gradients on different angles of lumbosacral of the control group. Also, in the experimental group, only the -3.7˚ had a significant effect on sacrum horizontal gradient, bearing in mind that, sacrum horizontal gradient is considered the most important indicator of hyperlordosis. Conclusions: We can conclude that in women with hyperlordosis, standing on -3.7˚gradient is effective on lumbosacral hyperlordosis.SOURCE: URMIA MED J 2013: 24(9): 651 ISSN: 1027-3727
