Examining Communication in ALS with Caregivers

This study is looking at how people with Amyotrophic Lateral Sclerosis (ALS) and their caregivers communicate verbally. Researchers want to understand how different ways of talking together affect speech in people with ALS, and if this changes over time. You and your caregiver would work together on tasks like reading words or describing pictures. The goal is to learn more about speech patterns in ALS during everyday interactions. To join, you must be between 18 and 90 years old, have an ALS diagnosis, no other neurological conditions, and some speech changes due to ALS. The study aims to include 76 people with ALS and their caregivers.

Study design
This is a single-group study involving 152 participants (76 people with ALS and 76 caregivers). All participants will complete the same tasks.
What's involved
You and your caregiver will participate in two 60-minute interactive sessions two weeks apart. In between these sessions, you will complete a word-matching task for about 10 minutes each weekday for two weeks at home.
Compensation
Not stated in the trial record.
Follow-up
Speech will be measured at two 60-minute sessions, two weeks apart. It is unclear if there is follow-up beyond these sessions.

  • Formant frequencies of speech soundstwo 60 minute sessions

    Formant frequencies that characterize speech sounds will be made on speech recorded in the intervention task.

  • Intelligibility of recorded speechtwo 60 minute sessions

    Perceptual judgments will be provided by solo, naïve listeners who did not participate in the interactions. Listeners will hear recorded speech of PALS and age-matched speakers recorded across the different tasks and indicate what they heard. The score will be expressed in percent. The possible range is between 0-100%. The higher scores mean a better outcome.

  • Syntactic propertiesTwo 60 minute sessions

    Syntactic complexity in the unstructured communication task will be measured through mean length of grammatical units, clausal density, and clause type. Each variable will be assessed at both the dyadic level (e.g., clausal density for both interlocutors together) and at the level of the individual speaker (e.g., clausal density of each speaker). A composite of these measures will provide an index of the syntactic complexity of the conversation.

  • Pragmatic PropertiesTwo 60 minute sessions

    The investigators will count the number and duration of silent portions of speech, filled pauses, linguistic mazes, speaking turns, and interruptions in the unstructured communication task. A composite measure of the individual measures will provide an index of an individual's contribution to the conversation.

  • Duration of speech soundstwo 60 minute sessions

    Durations that characterize speech sounds will be made on speech recorded in the intervention task.
