Hypothesis
What are the physical functions assessed by existing PBOMs and SROMs used to measure knee function and physical performance in people with knee OA, ACL injury, or patellofemoral pain (PFP)?
Conclusion
Current physical function outcome measures are not well suited to assess performance in knee OA populations with mild or diverse levels of impairment.
Supporting Evidence
- Climbing stairs was the most assessed physical function.
- Lower limb physical functions performance tests assess a limited number of activities.
- Knee OA outcome measures rarely assess challenging activities like running or jumping.
- Some issues related to the drafting of self-reported items were found.
Takeaway
This study looked at how different tests measure physical abilities in people with knee problems. It found that some tests miss important activities like jumping or running.
Methodology
A scoping review was conducted, screening 4146 articles and including 143 relevant studies.
Potential Biases
Self-reported measures may be affected by biases such as overestimation or underestimation of functional capacity.
Limitations
The review did not assess the psychometric properties of individual physical functions or the different ways of assessing these.
Participant Demographics
The studies included participants with knee OA, ACL injuries, and PFP, with a median age of 62 years for knee OA populations.
