Abstract: (724 Views)
Background: Chronic low back pain (CLBP) is one of the most common spine disorders, which is seen in 65-80% of people. Knowing the normal patterns of spine and pelvic parameters is very helpful in determining the susceptible subjects for CLBP.
Methods: This study was conducted in healthy people during April 2017 until April 2018 in Golestan hospital of Ahvaz. Inclusion criteria include; Age group 20-65 years, no history of surgery, spine disorders, and having normal radiographs were performed. People who have complained of back pain in the last three months, neuromuscular disease, lumbosacral anomalies, kyphosis and obvious scoliosis, history of spine surgery and vertebral fracture, were excluded. A 36-inch radiology stereotype was prepared in the standing position. Pelvic and spine parameters that were investigated in this research included the following, Pelvic incidence, Pelvic tilt, Sagittal Vertical Axis, T9 Sagittal Angle, Thoracic Kyphosis, Lumbar Lordosis, and Sacral Slope. All data were analyzed with SPSS software, version 24 (SPSS Inc., Chicago, IL, USA).

Results: 50 participants including 27(54%) men and 23(46%) women with an average age of 33±12.5 years and BMI of 25±5.5 kg/m2 were examined. After examining the vertebral and pelvic parameters, it was found that PI is significantly higher in women than in men (P=0.02). It was also found that with increasing age, the amount of Pelvic incidence also increases (P=0.043), so that in people over 60 years of age, the amount of pelvic incidence is significantly higher than other people (P<0.05). Further analyzes showed that BMI has a direct effect on the amount of Thoracic Kyphosis (P=0.03) and Lumbar Lordosis (P=0.04). Thus, the highest amount of Lumbar Lordosis and Thoracic Kyphosis was seen in people with BMI 30-34.9 Kg/m2.
Conclusion: The findings of the present study showed that spine and pelvis indices have an important effect on the occurrence of CLBP. Hence, it is highly recommended to check these parameters in asymptomatic people, especially in older people. |
