About this study
Official title: Which Factors Are the Strongest Predictors of a Positive Outcome After Physiotherapy for Patients With Knee Osteoarthritis?
Individuals with painful knee osteoarthritis (OA) experience restricted physical function. Few previous studies have investigated comprehensive sets of constructs and tests to investigate physical function in these patients. Most single studies of knee OA patients show limited scope for explaining physical function in the perspective of WHO's International Classification of Functioning, Disability and Health (ICF) 3 levels: Body functions (the bodily level), Activities (individual level), and Participation (societal level). On the bodily level there is limited case-control knowledge on muscle strength beyond the knee and endurance-strength in general. On the activity level, there is similar limitation of biomechanical bodily features in stair climbing. On the participation level the situation is similar for objective performance. Measures are needed that inter-relate all three levels of ICF. These should also include well discriminating tests e.g. knee strength, walking, and activities of daily life (ADL), as well as both objective and subjective measures.
The purpose of this study is to explore mechanisms that can explain physical function in patients with knee OA in primary care. The study's main and primary goal is to quantify which baseline factors and change scores are the strongest predictors of a positive treatment outcome in terms of patients' global perceived change after physiotherapy. Secondary research question is: which factors are the strongest predictors of a positive outcome of physiotherapy in knee OA, in terms of pain intensity, patient specific functional scale, and function in daily living?

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Individuals with painful knee osteoarthritis (OA) experience restricted physical function. Few previous studies have investigated comprehensive sets of constructs and tests to investigate physical function in these patients. Most single studies of knee OA patients show limited scope for explaining physical function in the perspective of WHO's International Classification of Functioning, Disability and Health (ICF) 3 levels: Body functions (the bodily level), Activities (individual level), and Participation (societal level). On the bodily level there is limited case-control knowledge on muscle strength beyond the knee and endurance-strength in general. On the activity level, there is similar limitation of biomechanical bodily features in stair climbing. On the participation level the situation is similar for objective performance. Measures are needed that inter-relate all three levels of ICF. These should also include well discriminating tests e.g. knee strength, walking, and activities of daily life (ADL), as well as both objective and subjective measures.
The purpose of this study is to explore mechanisms that can explain physical function in patients with knee OA in primary care.

Questions about this trial
What is this clinical trial studying?
An observational study of Osteoarthritis, Knee, run by Norwegian University of Science and Technology at 1 site in Norway.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 24 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Recruitment too slow, probably due to the procedure considered too complicated.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
patient global perceived effect (time frame: Change from baseline 'patient global perceived effect' at 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Nov 2017; AzTrials last refreshed its copy on 7 Nov 2026.
