Dry Needling Versus Percutaneous Electrolysis in Lumbar Multifidus Muscles in Patients With Chronic Low Back Pain
Dry Needling Versus Percutaneous Electrolysis in Lumbar Multifidus Muscles in Patients With Chronic Low Back Pain
The aim of this study is to evaluate the reduction of pain of two different treatments in patients with chronic low back pain. Patients were divided in two groups. The control group will receive DN treatment, and the experimental group will receive PE, both in the lumbar multifidus muscles.
Background: Low back pain is one of the most common health problems and a leading cause of disability and absence from work. Between 70% and 80% of adults will experience an episode of low back pain and approximately 10.0% of them will become chronic. This has a direct impact on the lumbar stabilizing muscles, giving rise to both structural and functional changes. Among the different treatment options, it has been observed that both dry needling (DN) and percutaneous electrolysis (PE) are effective techniques in the management of musculoskeletal pain.
Aim: To evaluate whether the reduction of pain after the application of PE is superior to the one obtained with DN.
Methods: A single-blind randomized clinical trial will be conducted in patients with chronic low back pain. The subjects will be divided into two groups. The control group will receive DN treatment, and the experimental group will receive PE, both in the lumbar multifidus muscles. The study variables will be: pain (VAS), disability index (Oswestry Scale), fear of movement (TSK-11SV) and quality of life (SF-12). The measurements will be assessed before, right after and 7 days after a single intervention.
