Given that recently the effectiveness of intratissue percutaneous electrolysis (EPI) has become of interest in the treatment of chronic musculoskeletal pain, when conventional physiotherapy management is not successful, the EPI can promote the healing biological processes. Several studies have demonstrated that inflammation can play an important role in the progression of muscle degeneration, in addition to potentially contributing to painful symptoms in individuals with chronic low back pain. This technique involves nonthermal, electrochemical ablation of the lesion via the use of a cathodic fluid. The inflammation provoked is very localized and healing is rapid. Although EPI has been widely employed lately, the literature contains few studies validating its use. The good results reported in studies of tendinopathies have to the undertaking of the present work, which compares the long-term effectiveness of EPI and dry needling-both ultrasound-guided-for the treatment of chronic low back pain. A double blind clinical trial will be developed in a sample of 80 subjects with chronic low back pain. Patients will receive 1 weekly sessions of intratissue percutaneous electrolysis for 3 weeks, for a total of 3 sessions. The aim is to compare the effectiveness of applying percutaneous electrolysis in the lumbar nerve root versus applying it to the trigger points of the gluteus medius, quadratus lumborum, and erector spinae muscles on disability, pain, fear of movement, quality of life, resistance of the trunk flexors, lumbar mobility and muscular electrical activity.
