A study funded by the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR).
Amyotrophic lateral sclerosis (ALS) is a nervous system disorder that interferes with how the brain and spine transmit signals to muscles and causes loss of motor function including mobility and speech. People with ALS (pALS) may experience such significant speech impairments that they cannot rely on their natural speech to meet their communication needs in face-to-face interactions.
