ExPa supports physicians in promoting PA in people with CBP by addressing multiple aspects of patient counselling (a.o. enhance physician-patient-communication, support patients in recognising the benefits of PA, and help them integrate PA in their lives). At the top is the screen showing the positive effects of PA on pain, mood and flexibility. At the bottom is the screen showing a catalogue of options to increase PA. The whole software is German as we conducted the study in German primary care practices. For publication, we translated the software in English
