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

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Forty adults with hip- or knee-osteoarthritis enrolled from a Swedish primary care program will perform the Ekblom-Bak submaximal ergometer bicycle test twice within 1-2 weeks after eligibility screening. The goal is to determine the test-retest reliability of the exercise test in this population. Exclusion criteria include other conditions or medications that affect heart rate or contraindications for the test. The findings could support using this test in routine clinical assessment if reliability is demonstrated. The study is led by Vastra Gotaland Region at Närhälsan Gibraltar Rehab in Gothenburg.
