Uterine Position and Pain and Central Sensitization Parameters in Women With Chronic Low Back Pain
ClinicalTrials.gov Studies
Summary
A new observational clinical trial (NCT07549009) registered on ClinicalTrials.gov will study the relationship between uterine position and chronic low back pain in women aged 18-75. The study will evaluate pain severity using the Visual Analog Scale and assess central sensitization via the Central Sensitization Inventory. Participants will be divided into two groups based on uterine position (posteriorly vs anteriorly positioned) and undergo pressure pain threshold measurements at multiple anatomical sites. No treatments or interventions will be administered; all data will be collected through face-to-face interviews using validated Turkish-language instruments.
“Female patients aged 18-75 years with chronic low back pain (lasting at least 3 months) will be included in the study.”
About this source
ClinicalTrials.gov is the NIH-run registry of every clinical trial conducted in the United States, plus most international trials sponsored by US-based companies or institutions. By federal law, sponsors must register Phase 2 through Phase 4 studies before enrolling patients and post results within a year of completion. This feed tracks every new trial registration and study update, around 700 a month: drug interventions, device studies, behavioral protocols, observational research. Watch this if you scout drug candidates moving into mid or late-stage development, monitor competitor pipelines, or follow rare disease research where new trials signal patient hope. GovPing parses sponsor, phase, intervention, and target indication on each entry.
What changed
A new observational clinical trial registration has been added to the ClinicalTrials.gov registry under NCT07549009. The study focuses on female patients aged 18-75 with chronic low back pain lasting at least three months, examining whether uterine position (posteriorly vs. anteriorly positioned) correlates with pain severity and central sensitization parameters. Participants will complete validated assessment tools including the Visual Analog Scale, Central Sensitization Inventory, and Pain Catastrophizing Scale, along with pressure pain threshold measurements at lumbar, gluteal, and deltoid sites. No interventions or treatments will be provided as part of the study protocol.
Healthcare providers and researchers treating women with chronic low back pain may find this registry entry useful for patient referral to ongoing research. Patients meeting the inclusion criteria (females 18-75, chronic low back pain ≥3 months) seeking participation in pain research may benefit from contacting the listed study investigators.

Uterine Position and Pain and Central Sensitization Parameters in Women With Chronic Low Back Pain
Observational NCT07549009 Kind: OBSERVATIONAL Apr 23, 2026
Abstract
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...
