Thus, it is a single-group study, with the participants being their own controls. 150 participants with osteoarthritis will be included. For this study, a mobile application will be developed. It will include self-administered questionnaires, allow physical activity data collection, and deliver the intervention (goal setting, data feedback, notifications to the user and self-completion questionnaires). The intervention will last 6 months, with a further 6-month follow-up.\n\nAfter signing the explicit consent and data protection notice, participants will encode data and information about individual and chronic pain characteristics, sport history, general health status: Individual questionnaire will include demographic data and general health status. The osteoarthritis pain questionnaire focuses on disease history and evaluation that will include a SF-WOMAC questionnaire. In order to deliver the same intervention for every participant, sham notifications will be send the first week, until the next Sunday for the first goals to be set. First real notification will be send the first Monday after the registration to the study.\n\nThe daily step count will be collected in background during the whole study. Then the intervention will be delivered though the phone application: each week, the participant will define a new daily step goal for the following week. Then he\u002Fshe will receive daily notifications (except Sundays) about physical activity, sedentary behaviour and their consequences on general health and osteoarthritis specifically.\n\nHe\u002Fshe will also be asked to fill in a pain questionnaire once a week. The participant can also spontaneously notify pain at any moment in the same questionnaire. At the end of each month, the participant will be asked about her\u002Fhis functional status with the WOMAC-SF questionnaire.\n\nAt the end of the 6-month intervention, a questionnaire will be sent to the participant to evaluate the application.\n\nDuring the 6-month follow-up, daily step count will still be collected in background, and pain questionnaires will be sent twice a month, but without any intervention delivered.",[41],{"label":42,"type":43,"description":44,"interventionNames":45},"Physical activity promotion","EXPERIMENTAL","The entire population will receive the physical activity promotion intervention, composed of weekly goal setting and daily notification with information about physical activity and sedentary behavior.",[46],"Behavioral: Physical activity promotion",[48],{"type":49,"name":42,"description":50,"armGroupLabels":51,"otherNames":36},"BEHAVIORAL","The intervention will be delivered through a phone application: each week, the participant will define a new daily step goal for the following week.
