Hip weakness may reveal hidden spine problems in back pain patients
NCT ID NCT07629466
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a simple hip weakness test (the Trendelenburg sign) is linked to spine problems seen on MRI in people with low back pain. Researchers will check MRI scans and measure hip strength in 120 adults aged 18 to 65. The goal is to better understand how hip function and spine health are connected.

Who is studied
Adults aged 18-65 years with low back pain and available lumbar MRI scans obtained within the previous 12 months. Participants will undergo clinical assessment for Trendelenburg sign and hip function, and lumbar MRI evaluation for degenerative changes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age between 18 and 65 years. * Patients who have previously presented to the clinic with a complaint of low back pain. * Willingness and ability to provide written informed consent for participation in the study. * Availability of lumbar MRI images obtained within the previous 12 months and accessible for evaluation. Exclusion Criteria: * Presence of red flag conditions associated with low back pain, including malignancy, infection, acute trauma, or significant neurological deficits. * History of lumbar spine surgery. * Structural spinal anomalies such as sacralization or lumbarization. * Spinal deformities, including scoliosis. * Rheumatologic diseases affecting the spine (e.g., axial spondyloarthritis). * Significant radiculopathy or advanced neurological deficits, and the presence of extruded or sequestrated lumbar disc herniation. * Clinically significant lumbar spinal stenosis. * Spondylolysis and/or spondylolisthesis. * Acute vertebral fracture, compression fracture, or recent fracture associated with severe osteoporosis. * Hip or pelvic conditions that may directly influence the Trendelenburg sign, including: History of hip arthroplasty or hip surgery, advanced hip osteoarthritis, residual deformity following lower-extremity fracture, significant leg length discrepancy (\>2 cm). * Systemic or neuromuscular disorders, including multiple sclerosis, myopathies, amyotrophic lateral sclerosis (ALS), stroke, or peripheral neuropathies. * Pregnancy. * Severe knee or ankle pathology or other conditions causing substantial gait impairment.
