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.

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.

Inclusion Criteria:

• The age range of 18-65
• Having non-specific LBP
• Volunteering to participate in the study

Exclusion Criteria:

• Having any psychiatric and mental problems
• The presence of any disc, bone, and muscular pathology in the lumbar region
• Having any previous operation on the lumbar region
