Animated Activity Questionnaire: Ny metode for funksjonsvurdering av pasienter med hofte- og/eller kneartrose
Sammanfattning
The development of the Animated Activity Questionnaire is a European project including
Denmark, France, Italy, the Netherlands, Spain, England and Norway. This paper is based on data
from the Norwegian part.
Objective: To test a computer-animated Questionnaire (AAQ), an innovative method for assessing
function in patients with hip and/or knee osteoarthritis (OA). The new method is compared with
established methods for measuring function.
Design: The study is a European collaborative project and has a cross-sectional design. The
Norwegian part is implemented as part of the research program FYSIOPRIM.
Material and methods: Patients with hip and/or knee OA and relatives were recruited from four
physiotherapy clinics. Patients answered questionnaires (HOOS/KOOS ADL and AAQ) and completed
performance tests. Relatives rated patient’s function using the AAQ. Five a priori hypotheses were
defined for validation of AAQ (construct validity).
Results: 60 patients with hip and/or knee OA and 29 relatives participated. The correlation between
AAQ scores for patients and relatives was very strong (r = .80). Patients AAQ-scores correlated
strong/very strong with both H/KOOS ADL (r = .74, p < .001) and with performance tests (r = - .63 to -
.66, p < .001). The correlation between pain and AAQ was weaker than between pain and H/KOOS ADL,
but stronger than between pain and performance tests.
Conclusion: Four out of five hypotheses were met, and it is concluded that AAQ is comparable with
established methods of function in patients with hip and/or knee OA (construct validity). The
standardized and readily available data-animated tool AAQ may be suitable for use in clinical
physiotherapy practice
