Clinical-use notice. This calculator is an unofficial scoring aid. The ALSFRS-R is a published, freely used instrument (Cedarbaum et al., 1999); the item descriptions here reproduce its standard wording for scoring convenience. It does not replace clinical judgment, training, or the source publication, and stores no data outside this browser.
