The research question
How do pain and function change alongside routine treatment, activity and weight-management efforts?
Proposed design
Observational diary with periodic condition-specific function assessments; steps or performance tests can be added after validation.
Illustrative design: 12-week follow-up; setup and recruitment are scoped separately.
Data to collect
- Knee pain and stiffness
- Walking and daily-task difficulty
- Reported activity and analgesic use
- Weight measurements with recorded provenance
Planned outputs
- Pain and function trajectories
- Reported treatment and activity patterns
- Within-person variation and missing-data summaries
What we confirm with you
We agree the population, sample size, country, collection tools, analysis plan and budget. Collection starts after the required consent, ethics or other permissions and a signed scope are in place.
- Confirm osteoarthritis diagnosis and symptom location
- Check function-scale permissions
- Do not infer structural joint changes from patient reports
Clinical records, laboratory results, photographs and device integrations are included only when access, collection quality and permitted use have been verified. Self-reported findings are identified as such.
