About

One of the important causes of low back pain is lumbar spinal stenosis. With the increasing prevalence of magnetic resonance imaging (MRI), lumbar spinal stenosis grading systems have been developed. The Lee and Schizas lumbar spinal stenosis grading systems are widely used. Patient questionnaires are also used especially in treatment follow-ups. This study aimed to compare the compliance of patient questionnaires with the presence or absence of radiological stenosis and the degree of stenosis if present.

Full description

Patients who apply to our Physical Medicine and Rehabilitation out-patient clinic with complaints of low back pain and who have or do not have lumbar spinal stenosis on lumbar spinal MRI will be screened. Demographic values, accompanying diseases, radiological staging of lumbar spinal stenosis, Oswestry Disability Index, Istanbul Low Back Pain Disability Questionnaire, Swiss Spinal Stenosis Questionnaire will be evaluated. Pain levels will be evaluated with Visual Analog Scale (VAS). Radiological stenosis level will be determined with Lee radiological spinal stenosis classification system. Those with and without stenosis will be determined. In addition, subgroup analysis will be performed by creating subgroups with mild, moderate and severe stenosis in the stenosis group. Evaluations will be made at the L4-L5 vertebrae level, where degenerative spinal stenosis is most frequently seen. All questionnaires will be filled in both groups with and without stenosis.
