Official title

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

Overview

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.

Interventions

  • Procedure Submaximal cycle ergometer test-retest
    Performing a submaximal cycle ergometer test twice

Primary outcome measures

  • Estimated VO2-max value. [Time frame: Time between first and second submaximal cycle ergometer test should be one week.]

Eligibility criteria

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.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
