Background: A previous study examined the relationship between the sacral inclinationangle (SIA), lumbosacral angle (LSA) and sacral horizontal angle (SHA) and spinal mobility in acute low back pain and chronic low back pain patients. We chose to investigate thelumbar lordosis angle, segmental lumbar lordosis angle, SIA, LSA and SHA in acute andchronic low back pain (LBP) patients as well as the correlation between spinal stability andthese angles.Objectives: To investigate the biomechanics of the lumbosacral spine region in acute andchronic LBP patients, as well as to examine the correlation between spinal stability and lumbosacral angles.Study Design: Randomized controlled evaluationSetting: Physical Medicine and Rehabilitation outpatient clinicMethods: Sixty participants with LBP were recruited and categorized as either acute LBP(pain 6 months), with 30 subjects in each group. All subjects underwent standing, lateral lumbosacral x-rays, which were analyzed for lumbar stability, SIA, LSA, SHA, lumbar lordosis angle and segmental lumbar lordosis angles.Results: The mean age of the ALBP subjects was 41.00 ± 11.63 (18 – 66) and that of thechronic LBP subjects 49.26 ± 15.6 (22-74), with females comprising 50% of the acute LBPgroup and 73.3% of the chronic LBP group. Lumbar stability was observed in 62.1% ofacute LBP patients and 36.8% of chronic LBP patients. A statistically significant differencewas found between the 2 groups in terms of age, gender, and lumbar stability. There wasno statistical difference regarding SIA, LSA, SHA, total and segmental lordosis angles between acute and chronic LBP patients (p>0.05).Conclusion: We were unable to find a difference between the radiological values for theshape of the SIA, LSA, SHA, and total and segmental lordosis as noted on screening x-raytechniques regarding the occurrence of acute or chronic LBP, but a statistically significantdifference was found for lumbar stability. Further extensive studies are needed to examinelumbar stability and its relationship between angles of lumbosacral region.Key words: biomechanic, acute low back pain, chronic low back pain, lumbar stability,lumbosacral, sacral, lumbar lordosis
