Can we reduce trial burden and improve remote clinical monitoring for people living with amyotrophic lateral sclerosis with an imperfect tool?

In this issue, Bakker and colleagues report on the development and assessment of the performance of a self-administered version of the revised amyotrophic lateral sclerosis functional rating scale (ALSFRS-R).1

The ALSFRS, subsequently revised to ALSFRS-R is a functional outcome measure for ALS trials and has been shown to correlate with survival and muscle strength.2 As an outcome measure, it is not without its problems including multidimensionality, non-linearity, poor sensitivity to change in latter stages of disease and the absence of a cognitive function domain.3 4
