Test-Retest Reliability of a Submaximal Exercise Test in Patients With Hip and Knee Osteoarthritis
40 participantsStarted 2026-03
Plain-language summary
The aim is to evaluate the test-retest reliability of the primary care-adapted Ekblom-Bak submaximal ergometer bicycle test in patients with hip- and/or knee osteoarthritis (OA).
Forty patients with hip- and/or knee OA eligible for the Swedish national OA treatment program in primary care are to be recruited. After screening for contraindications, participants will perform the aEB-test twice within 1-2 weeks.
The investigators hypothezise that the test will demonstrate acceptable test-retest reliability in patients with hip- and/or knee OA.
To establish reliability is essential for future studies using this test in this population and may support its integration into routine clinical assessment.

Inclusion Criteria:
* Currently listed on the waiting list for an osteoarthritis rehabilitation program due to clinically diagnosed hip and/or knee osteoarthritis.
Exclusion Criteria:
* Another primary cause of symptoms or disability, such as inflammatory joint disease or fracture.
* Another condition currently causing more symptoms than osteoarthritis, for example fibromyalgia.
* Insufficient understanding of written and spoken Swedish.
* Medication that affects heart rate.
* Contraindications for a submaximal ergometer bicycle test according to the screening protocol, such as heart disease.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
