NCT04081207

Brief Summary

The currently available interventions only partially restore language abilities in patients with post-stroke aphasia; preventing successful reintegration into society. This study will increase our knowledge of how we can use assistive technology interventions to help people with aphasia restore language function. Further, this project will help us identify regions of the brain responsible for these changes.

Outcome Measures

Primary Outcomes (3)

  • Western Aphasia Battery-Revised Aphasia Quotient

    a diagnostic tool used to determine aphasia type and severity

    3 years

  • Visual Regions of Interest Activation intensity

    A functional magnetic resonance imaging (fMRI) measure to indicate change in brain involvement during resting state and language tasks.

    3 years

  • Connectivity Indices

    Connectivity indices reflect the temporal correlation between canonical language and visual regions of interest during language and resting state fMRI tasks.

    3 years

Secondary Outcomes (8)

  • Motor-Free Visual Perception Test-4

    3 years

  • Discourse Analyses

    3years

  • Communication analyses

    3 years

  • Stroke and Aphasia Quality of Life-39 (SAQOL-39)

    3 years

  • Communication Effectiveness Index (CETI)

    3 years

  • +3 more secondary outcomes

Study Arms (1)

AAC-LaRc

EXPERIMENTAL

all participants receive the experimental treatment

Behavioral: AAC for Language Recovery (AAC-LaRc)

Interventions

iPads will be programmed with a personalized communication application (app) and a structured 4-step intervention will be employed to instruct patients how to cue themselves during anomic events via pictures, text, or speak buttons.

Intervention Model
SINGLE GROUP
Model Details: Participant cohorts: We will use a 2 (groups) X 4 (measurement time points) switching replications design\[18\] to examine the effects of AAC on aphasia severity and spoken language (AIM 1), elucidate the neurobiological mechanism of AAC-induced language recovery (AIM 2), and identify AAC treatment responder subgroups (Exploratory Aim). This design will allow Group 2 to serve as the control group; however, they will still receive AAC treatment; thus, allowing us to increase the total N who receives AAC treatment to 20 people.

Data Sharing

IPD Sharing
Will share

Even though the final dataset will be stripped of identifiers prior to release for sharing, we believe that there remains the possibility of deductive disclosure of subjects based on their private health information and language profiles. Further, it is possible to reconstruct faces from MRI data and the patients are easily identified through the testing and treatment videos; thus, we will make the data and associated documentation available to users only under a data-sharing agreement that provides for: (1) a commitment to using the data only for research purposes and not to identify any individual participant; (2) a commitment to securing the data using appropriate computer technology; and (3) a commitment to destroying or returning the data after analyses are completed. Data will be shared at the time of publication, or shortly thereafter.
