Brief summary

The purpose of this study was to examine the relationship between non-specific low back pain (NSLBP) and lumbar lordosis angle (LLA) and lumbar muscle thickness (LMT) by evaluating magnetic resonance images (MRI) in individuals with LBP.

Detailed description

The study included a total of 96 individuals, 43 males, and 53 females, who applied to the Department of Radiology of the Karabuk University Training and Research Hospital between March-June 2019 with complaints of LBP. Individuals' sociodemographic information and medical history were recorded using the LBP assessment form. The Oswestry LBP Disability Questionnaire was used for LBP. Thickness measurements of muscle (m.) psoas major, m. multifidus, m. quadratus lumborum and m. erector spinae were taken on MRI corresponding to the L3-L4 vertebra level. Cobb Angle method was used for LLA determination. Measurements were made in three repetitions using the Radiant DICOM viewer program, and their averages were recorded.

Design outcomes

Primary

MeasureTime frameDescription
Disability caused by low back pain assessed by Oswestry Low Back Pain Disability Questionnaire6 monthsLow back pain disability is assessed with Oswestry Low Back Pain Disability Questionnaire. Oswestry Disability Index (ODI) score as a percentage is obtained from the questionnaire result.
Lumbar lordosis angle6 months* Measured with the COBB angle method as LLA degree. * It is determined by looking at the angle between the vertebrae forming the lumbar lordosis curvature (L1-L5). * All radiological measurements are performed on the RAdiant DICOM viewer program.
Muscles thickness measurements6 months* Measured on the horizontal plane corresponding to the L3-L4 level in the sagittal plane. * Bilaterally, the thickest parts of the muscles are measured anterior-posterior and transverse and recorded in millimetres (mm). * All radiological measurements are performed on the RAdiant DICOM viewer program. * Muscles measured are listed below: * m. psoas major * m. multifidus * m. erector spinae muscles * m. quadratus lumborum
