Summary
Brief summary
The aim of this study is to evaluate the effect of educational information, with and without
a general practitioner recommendation to exercise, on willingness to undertake
exercise/physical activity for knee osteoarthritis. Eligible participants will be aged 45+
years and will not currently have osteoarthritis, knee pain, or any condition that makes them
unable to exercise. Participants will be asked to complete an online survey, during which
they will be randomised to one of three groups and shown different types of educational
information to read. Outcome measures will be collected as part of the survey before and
after participants read the educational information presented to them.
