Official title
Home Telemonitoring of Bulbar Function by Acoustic Measurement of Swallowing and Speech Sounds in ALS
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators propose a longitudinal home study of ALS patients to measure the severity of speech and swallowing (bulbar) impairment via a smartphone-based, remote speech and swallow assessment (rSSA). The study is designed to assess the feasibility and validity of such a monitoring intervention. Furthermore, it is proposed that regular monitoring of these two bulbar processes may shed light on their co-evolution over the course of ALS.
