Conditions
Summary
This study aims to learn how symptoms and daily functioning change over time in people with hip or knee osteoarthritis (OA). The goal is to use this information to build computer models that can predict these changes. In the future, these models may help give people with OA the right self-care advice at the right time through a web application called ArtroseCoach. People with OA will take part in this study for one year. Every two weeks, they will fill in online questionnaires covering various aspects of their health and daily functioning, such as pain, daily activities, and participation in life. During the year, participants will be randomly assigned to one of several self-care programs in the ArtroseCoach web app. These programs focus on physical activity, weight management, or sleep. Each program lasts 12 weeks. At four points during the year (weeks 3, 15, 27, and 39), participants will receive one of these programs or no program at all. No one will receive the same program twice. The ArtroseCoach web app provides education about OA, lifestyle advice, and tips to support behavior change. The study will help researchers understand which factors are linked to changes in pain and physical functioning over time. This knowledge will be used to improve the ArtroseCoach and other future tools that support people with OA in managing their condition on their own.
Eligibility
Inclusion Criteria9
- Have a hip or knee joint that, self-administered through a questionnaire, meets the National
- Institute for Health and Care Excellence clinical criteria for osteoarthritis:
- Aged 45 years or over and;
- Activity-related pain at the joint and;
- Joint morning stiffness that lasts no longer than 30 minutes or no morning stiffness at the joint;
- History of pain at the joint for at least 3 months;
- Have access to a smartphone with internet connection and an email address;
- Able to give informed consent and willing to commit to all study evaluation and assessment procedures
- Able to read and understand texts in Dutch at B1 level.
Exclusion Criteria2
- Self-reported systemic arthritis (e.g., rheumatoid arthritis, gout) avoid confounding due to overlapping symptoms;
- Scheduled for lower limb joint surgery within the next year or underwent lower limb joint surgery (total hip, total knee) the last year as surgical interventions could affect outcomes and confound the assessment of treatment effects.

Interventions
Aims to increase knowledge and levels of physical activity, and improve muscle strength through three components: 1. weekly education on movement, pain, energy management, and recommended moderate to vigorous physical activity levels; 2. a graded activity module with baseline measurement (Fitbit Inspire 3 or self-reported physical activity), goal setting, weekly increases of 10% moderate to vigorous physical activity, and reinforcement; 3. strength exercises provided via instructional videos, performed twice weekly for 20 minutes. The physical activity program is developed in line with existing osteoarthritis guidelines and builds on previous research done by our team.
Aims to improve insomnia severity through three components, in line with insomnia guidelines: 1. weekly education on sleep and sleep hygiene, including recommended behaviours to promote sleep hygiene (e.g., relaxation, consistent routines, environment modification, limiting caffeine and screen time); 2. behaviour change support with goal setting, tailored feedback, and prompts to encourage healthier sleep habits. 3. mindfulness exercises such as progressive muscle relaxation and meditation.
Supports participants in adopting a healthier diet and achieving a healthier weight if needed. Participants can monitor their weight, complete a food frequency questionnaire (FFQ) for personalized feedback, and select food components to focus on. The FFQ represents the Dutch food-based dietary guidelines. Participants receive daily tips and weekly information on healthy eating and weight loss.
For 12 weeks, participants receive no program. They only fill in questionnaires through the ArtroseCoach web-app.
