Brief Summary

Background: It is estimated that 14% of the Swedish population have knee osteoarthritis. Common osteoarthritis symptoms are pain, stiffness and impaired physical function. To evaluate muscle strength in the lower extremities could indicate if there is a risk for a patient with osteoarthritis to worsen their disease. Increased muscle strength could improve physical function and pain for this patient group. A reliable self-test to evaluate physical function could help patients with diagnosed or suspected knee osteoarthritis to seek healthcare in time. The 30 seconds chair stand test (30 CST) is part of a test battery which is recommended to use for patients with osteoarthritis, both in research and in a clinical setting. It is a valid and a reliable measurement for patients with osteoarthritis. However, reliability studies of the 30 CST as a self-test is lacking. Objective: To determine whether 30 CST is a reliable self-test to evaluate physical function among patients with knee osteoarthritis, we want to explore how much it differs in the test results when the patient is performing the test by herself and also compare it with when it is conducted in a clinical setting. Methods: 147 participants with knee osteoarthritis will be recruited from three rehabilitations centers in primary care. The participant will perform the self-test twice at home, and the self-test will be compared with when the test is guided by a physical therapist at a rehabilitation center. The reliability results will be presented with an intraclass correlation coefficient and standard error measurement. Estimated results: It is expected that the results from this study will clarify if 30 CST can be used as a self-test for persons with suspected or diagnosed/confirmed knee osteoarthritis. If this performance test show enough reliability to be used as a self-test, it could be used as an indicator if the patient should seek healthcare or not due to impaired function. To seek healthcare in an earlier phase usually require less efforts and often leads to shorter healthcare process. These improvements of the healthcare process could be of value to manage the expected future increase of osteoarthritis consultations to primary care.

Study Arms (1)

Test-retest reliability

OTHER

Patients with knee osteoarthritis will perform the 30 seconds chair stand test as a self test twice at home to evaluate intra rater reliability. Same patients will be tested with the same performance test by a physical therapist to evaluate the inter rater reliability.

Other: Intra rater reliability; Other: Inter rater reliability

Interventions

Intra rater reliability OTHER

Patients will perform the 30 seconds chair stand test as a self-test twice at home with approximately two days apart. The last self-test should be performed approximately one week before the testing with a physical therapist.

Test-retest reliability

Inter rater reliability OTHER

Same patients performing the self-test will be tested by a physical therapist approximately one week after the last self-test. The physical therapist will be blind to the self-test results.

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients diagnosed with knee osteoarthritis. The patients should have most problem with their knees, but are allowed to have osteoarthritis in other lower extremity joints.
• Independent in walking, with or without walking aids.
• Understand test instructions verbally and in writing.

You may not qualify if:

• Neurological disorders that affects the patients balance or gait.
• Severe somatic or mental illness that affect the physical functional performance or the ability to understand test instructions verbally or in text.
• Knee or hip replacement the past six months.
• Other knee surgery the past six months that could affect the physical functional performance.
