Validity and Reliability of Video-Based Functional Physiotherapy Assessment of Subacute Knee Injuries
Sponsor: Vastra Gotaland Region
Summary
This study aims to validate a function-based physiotherapy assessment for subacute knee pain without using specific knee tests. Assessments are conducted either in-person or via video consultations in primary care. The study also compares the reliability of digital versus physical assessments to determine if video-based evaluations can provide sufficient diagnostic support and guide treatment decisions. The main questions this study aims to answer are: 1. Is a function-based knee assessment without specific knee tests valid compared to traditional in-person diagnostics using specific tests? 2. Is a video-based assessment based on history and function-based knee assessment without specific knee tests as valid and reliable as an in-person function-based knee assessment? 3. What is the interrater agreement of function-based knee assessments conducted via video compared to those conducted in person?

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