Brief summary (from the registry)
Female patients aged 18-75 years with chronic low back pain (lasting at least 3 months) will be included in the study. Demographic data including age, height, weight, educational status, marital status, and comorbidities will be recorded. In addition, clinical characteristics such as pain duration, pain distribution, analgesic use, and concomitant musculoskeletal disorders will be assessed. Uterine position will be evaluated based on pelvic magnetic resonance imaging (MRI) or pelvic ultrasonography reports obtained within the last year. According to uterine position, participants will be divided into two groups: posteriorly positioned uterus (retroverted and/or retroflexed uterus) and anteriorly positioned uterus (anteverted uterus). Pain severity will be assessed using the Visual Analog Scale (VAS), and pain duration will be recorded in months. Pressure pain threshold measurements will be performed using an algometer at bilateral lumbar paraspinal muscles, gluteal regions, and the mid-deltoid muscle as a remote control point. Central sensitization will be assessed using the Central Sensitization Inventory (CSI), and pain catastrophizing will be evaluated using the Pain Catastrophizing Scale (PCS). All assessments will be conducted through face-to-face interviews. No additional laboratory tests, interventional procedures, or treatments will be applied to the participants within the scope of the study. Validated Turkish versions of all scales will be used. The collected data will be analyzed to investigate the relationship between uterine position and pressure pain threshold, central sensitization, and pain catastrophizing levels in women with chronic low back pain.
