Online Intervention Based on Pain Neuroscience Education for Women with Pregnancy-related Lumbopelvic Pain

The patients in the intervention group will receive, in addition to the prenatal educational content, the 12 Pain neuroscience education lessons in audiovisual format. Each lesson will last between 10-15 minutes. The contents of PNE will be an adaptation, focused on the context of a pregnant woman, of the Butler \& Moseley postulates. These contents have already been previously adapted according to the nature of the patients' pain, both in chronic pain and in acute pain. In summary, the participants will receive a detailed explanation about the biopsychosocial component of pain through the use of diagrams, metaphors and practical examples. In turn, the objectives of this program could be summarized as: (1) Reformulate erroneous beliefs about pain, (2) Inform about the biology and protective nature of pain and (3) Provide techniques to reduce kinesiophobia and, consequently, promote physical activity, with the beneficial effect it entails for patients with pain.

The standard prenatal education is based on the Pregnancy and Postpartum Clinical Practice Guide, consisting of general information about pregnancy (visits and monitoring of pregnancy, diet, phases of delivery, lactation, etc.), as well as specific recommendations for lumbopelvic pain associated with pregnancy. These contents will be developed by midwives from the participating hospitals. Participants will receive 12 educational sessions, with an estimated duration of 10 minutes each.
