Arsalis has also acquired expertise in PROMs development for the assessment of patients’ function in clinical practice and research for various pathologies. Our approach utilizes the state-of-the-art outcome measures, the Rasch measurement, to ensure the highest standards of accuracy in patient assessment.
The Rehab-scales web site has been developed in the late 1990's at Université catholique de Louvain (UCLouvain), in the lab of rehabilitation by a group of researchers specialized in the assessment of rehabilitation outcomes. Recently, the Rehab-scales web site has been further developed in collaboration with Haute Ecole Louvain en Hainaut (HELHa).
All Rehab-scales have been developed with the Rasch model, a state-of-the-art item response model that allows continuous, linear and unidimensional functional measurement along the patient follow-up. The scales are developed to cover a wide range of pathologies as of outcomes meaningful to rehabilitation. All Rehab-scales can be used free of charge for daily clinical practice and research and have been translated in more than 70 different languages. A license is required to use any Rehab-scale in a clinical trial or in a commercial application. The licenses are distributed by Arsalis SRL, a spin-off of our university lab. Many members of the lab are now teaching rehabilitation and outcome measurement at UCLouvain and HELHa or in other high schools.
