Digital Assessment of Speech and Fine Motor Control in ALS

This is a single-session, case-control study that incorporates digital tools for assessing speech and motor function in motor neuron disease. Patients with motor neuron disease (including amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), and progressive muscular atrophy (PMA)) and age-matched healthy controls will be enrolled. Subjects will complete a speech and handwriting assessment during the study visit on a tablet computer (BioSensics LLC, Newton, MA). We will explore whether these digital biomarkers are sensitive to functional disease severity as reported by the ALS Functional Rating Scale - Revised (ALFRS-R) \[1\]. We will also compare assessment data between the patient and control groups.
