Test-Retest Reliability of a Submaximal Exercise Test in Patients With Hip and Knee Osteoarthritis

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.
