The goal of this clinical trial is to evaluate whether auricular vagus nerve stimulation using the VIVO® device can improve function and reduce pain in adults with high-impact chronic low back pain when added to standard medical care. It will also assess the safety and usability of this therapy. The study includes adult patients aged 30 to 55 years who have had moderate to severe chronic low back pain for more than 6 months and who did not experience sufficient relief with standard pain treatments. The main questions this study aims to answer are: * Does adding the VIVO® device to standard care help people function better in daily life? * Does the VIVO® device help lower pain and improve wellbeing, sleep, and quality of life? Researchers will compare standard care plus VIVO® to standard care alone to see if the device improves outcomes. Standard care may include medication, physiotherapy, or other usual treatments. The main outcome is the change in disability (measured using the Oswestry Disability Index) after 6 weeks of treatment. Participants will: * Attend a baseline visit where medical history, physical examination, and questionnaires about pain, function, mood, sleep, and quality of life are collected; * Be randomly assigned to one of the two treatment groups; * Attend weekly visits for 6 weeks during the treatment phase; * Keep a diary of their pain levels and any treatments or medications used; * Complete questionnaires about pain, function, sleep, and wellbeing during the study. Participants in the intervention group will: Receive a VIVO® wearable device applied to the ear, which delivers electrical stimulation to the vagus nerve; Use the device continuously over 6 weeks, with weekly replacement and adjustment of stimulation settings; Be able to adjust the stimulation intensity themselves using a handheld device. After the treatment period, all participants will be followed for 12 months, with additional visits or contacts to assess long-term effects, safety, and sustainability of the treatment.
