Brief summary (from the registry)
The aim of this study is to analyze the effect of Repeated Peripheral Magnetic Stimulation (rPMS) in patients with chronic low back pain. This is a controlled, randomized, multicenter clinical trial (Brazil x Portugal). The sample will consist of individuals with chronic low back pain with a score between 40 and 80 on the Oswestry scale, who will be randomly divided into 2 groups: control (CG) and intervention (IG). The instruments used for evaluation will be: visual analog pain scale (VAS), brief pain inventory (BPI), McGill questionnaire, Roland Morris scale and WHOQOL-BREF. Both groups will use the EMP device, with 10 sessions over a period of 2 weeks, in the IG applied in the flat tangential orientation lasting 20 minutes and an intermittent stimulation protocol consisting of 5 seconds of stimulation at a frequency of 20 Hz followed by 25 seconds of rest with a minimum intensity of 20% up to the maximum intensity to induce sufficient contraction of the paraspinal muscle and in the CG in transverse orientation with the stimulus intensity level set at 5% of the maximum output of the stimulator to minimize stimulation, both in the most painful lumbar region. The Wilcoxon test will be applied. Then, the Mann-Whitney test will be applied, adopting a significance level of 5%. It is expected that this research will contribute to more accurate protocols and evaluation methods for the EMP intervention, which generates responses in pain relief and non-surgical treatment.
