NCT ID NCT07383740
First seen Jun 25, 2026 · Last updated Aug 21, 2026 · Updated 3 times
Summary
This study aims to see if a submaximal bike test, called the Ekblom-Bak test, gives consistent results when repeated in people with hip or knee osteoarthritis. Forty patients will take the test twice, one to two weeks apart. The goal is to determine if this test can be reliably used in routine care to estimate fitness levels in this population.
