About Us
ALS-OPM.org is an academic initiative of leading ALS centers across Europe, dedicated to standardizing the phenotypic classification of ALS. By providing a consistent framework for describing ALS motor phenotypes (OPM Classification) and harmonizing the assessment of the ALS Functional Rating Scale in its revised, self-explanatory form (ALSFRS-R-SE), we aim to strengthen comparability in clinical practice and research across countries. This website offers open-access, nonprofit resources for the latest versions of the OPM Classification and ALSFRS-R-SE in multiple languages, practical guidance for phenotype classification, and scientific publications from participating ALS centers.
