How long does the positive effect of a three-week treatment with open-label placebos (OLP) last in chronic back pain? This research question was posed by the team led by Dr. Julian Kleine Borgmann and Prof. Ulrike Bingel from the Center for Translational Neuro- and Behavioral Sciences at the University Hospital Essen, where they started a three-year follow-up study. The results have now been published as a research paper in the journal PAIN and can be read here. After three years, the effect was no longer detectable in terms of pain intensity, movement restrictions and mood. Read more about the study here!
