The overall aim is to educate women to handle common pregnancy-related pain experiences to facilitate healthy life-long physical activity habits and prevent chronic pain. Our developed WOMENinMOTION model with person-centred preventions and interventions focused on management of pain components added to usual care, will be evaluated in a randomized control study against usual care. Data and method The model WOMENinMOTION is built on pain education and management of the sensory, emotional, and cognitive components of pain. Through pain management and motivation, pregnant women are guided to choose personal tools for health-promoting physical activity and adaptation of daily activities. Instructive films of exercises, pelvic belt application, and knowledge to meet worries are provided digitally. When the digital content is insufficient, the model is supported by physiotherapist.
