Agreement Between the Harmonized and the Self‐Explanatory Versions of the Revised <scp>ALS</scp> Functional Rating Scale in a Clinical Setting

The strong agreement between the harmonized and self-explanatory versions of the ALSFRS-R supports their interchangeable use. The SE format may facilitate remote digital assessment and reduce complexity of ALSFRS-R assessment in research and clinical practice. Further studies are warranted to validate the ALSFRS-R-SE across larger cohorts, multiple languages, and diverse rater groups.
