localized between the lower costal margin and the gluteal fold, with at least 12 weeks of evolution.\n* Lumbar pain intensity of at least 5\u002F10 on the Numeric Pain Rating Scale (NPRS).\n* Predominantly mechanical pain, exacerbated by activities such as prolonged standing, trunk movements, extension, or lumbar rotation, and without clinical data of predominant radicular pain.\n* Plain radiograph of the lumbar spine available as part of the baseline evaluation.\n* Ability to attend all 4 treatment sessions and subsequent follow-up evaluations.\n* Signed informed consent form previously approved by the Institutional Review Board \u002F Research Ethics Committee.\n\nExclusion Criteria:\n\n* Low back pain of probable non-mechanical origin or secondary to a specific cause that substantially modifies clinical management.\n* Clinical data of predominant lumbar radiculopathy, including pain radiating below the knee with a dermatomal distribution, focal motor deficit, objective sensory alterations, or compatible reflex changes.\n* Diagnosis or suspicion of cauda equina syndrome.\n* History of previous lumbar spine surgery.\n* Current vertebral fracture or recent history of lumbar fracture.\n* Spondylolisthesis grade II or higher.\n* Significant structural scoliosis or severe lumbar deformity that prevents treatment standardization.\n* Suspicion or evidence of a tumor, infection, spondylodiscitis, or axial inflammatory disease.\n* Severe clinically documented osteoporosis or history of vertebral fragility fracture.\n* Pregnancy or lactation.\n* Coagulation disorder, use of anticoagulants at therapeutic doses, or a hemorrhagic condition that increases procedure risk.\n* Previous epidural infiltration, facet block, radiofrequency, or other lumbar interventional procedure within a recent period defined by the protocol.\n* Current treatment with another physical rehabilitation modality or instrumental therapy directed at low back pain, if it cannot be suspended during the intervention period.\n* Current use of nonsteroidal anti-inflammatory drugs (NSAIDs) that the patient cannot suspend according to the study indications.\n* Concomitant neurological, rheumatological, oncological, or musculoskeletal disease that significantly interferes with pain or disability evaluation.\n* Cognitive impairment, decompensated psychiatric disorder, or any condition that prevents understanding instructions, answering questionnaires, or completing follow-up.","ALL","18 Years","80
