Testing Digital Tools to Measure Speech and Hand Function in ALS

This trial examined whether digital assessments of speech and fine motor control—such as recording how someone speaks or measuring handwriting patterns—could provide a more detailed picture of how ALS and related motor neuron diseases progress. The researchers collected speech and handwriting samples from people with ALS, primary lateral sclerosis, or progressive muscular atrophy, as well as from healthy volunteers, and compared the digital measurements to standard clinical assessments.

Doctors currently use a questionnaire called the ALSFRS-R to track how ALS affects patients over time, but this tool can be too general and may miss small but important changes in how people speak or use their hands. This trial was designed to explore whether detailed digital measurements could catch these changes more accurately and help clinicians monitor disease progression better.
