The purpose of this clinical trial is to evaluate and compare the efficacy of two different dosing regimens of focal extracorporeal shock wave therapy (F-ESWT) in patients diagnosed with chronic mechanical low back pain. Participants will be randomly assigned to one of two experimental groups to receive different parameters of shock wave intervention. The main objective is to determine which dosing scheme provides a more significant reduction in pain intensity and a better recovery of lumbar function.
Individuals of both sexes.
Age between 18 and 65 years.
Clinical diagnosis of mechanical chronic low back pain (cLBP), defined as pain localized between the lower costal margin and the gluteal fold, with at least 12 weeks of evolution.
Lumbar pain intensity of at least 5/10 on the Numeric Pain Rating Scale (NPRS).
Low back pain of probable non-mechanical origin or secondary to a specific cause that substantially modifies clinical management.
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.
Diagnosis or suspicion of cauda equina syndrome.
History of previous lumbar spine surgery.
