Validity and Reliability of Video-Based Functional Physiotherapy Assessment of Subacute Knee Injuries

This study involves three types of knee assessments to evaluate diagnostic reliability and validity: (1) a video-based function-based examination without specific knee tests, (2) traditional in-person function-based examination without specific knee tests and to control with (3) a traditional in-person examination including specific knee tests. The video-based assessment includes standardized history taking and functional evaluation conducted via clinic software, with the physiotherapist and participant in separate rooms. Physiotherapists provide diagnostic judgments after each assessment phase. All procedures follow standardized protocols, pilot-tested and conducted at a public rehabilitation clinic in Västra Götaland.

The in-person assessments (2 and 3) includes the same functional tests plus specific tests targeting knee structures (ligaments, meniscus etc).
