BCI-FIT Trial Summary

This trial is testing a new brain-computer interface (BCI) that does not require surgery for people with severe speech and physical impairments. The goal is to improve communication for people with these impairments.

Who is the study for?
This trial is for adults aged 18-89 with severe speech and physical impairments due to conditions like ALS, muscular dystrophy, or brainstem stroke. They must be able to communicate in English and participate in study visits lasting up to 3 hours. Life expectancy should be over 6 months. Excluded are those who can't tolerate weekly visits, have skin risks from hardware contact, unstable medical conditions, certain implants, or photosensitive seizures.Check my eligibility
What is being tested?
The BCI-FIT toolkit is being tested which includes adaptive signal modeling and active querying techniques for improving communication through brain-computer interfaces (BCI). It aims to optimize typing speed and accuracy for people with severe speech and physical impairments by using multi-modal signals.See study design
What are the potential side effects?
Since this trial involves non-invasive technology rather than medication, traditional side effects are not a concern. However, participants may experience fatigue during long sessions or discomfort from the equipment used.

BCI-FIT Trial Design

4Treatment groups
Experimental Treatment
Group I: Language modelingExperimental Treatment1 Intervention
For this single case research design with alternating treatments, 5 control volunteers and 5 participants with severe speech and physical impairment, each with a control partner for partner input will complete a story retell task with BCI-FIT language modeling features on and with BCI-FIT language modeling features off. Outcome measures are information transfer rate and user experience.
Group II: BCI-FIT multi-modal configurationExperimental Treatment1 Intervention
For this single case research design with alternating treatments without baseline, 5 participants with severe speech and physical impairment will complete copy spelling tasks with a standard P300 matrix speller layout and with the multi-modal configurations optimized from the BCI-FIT algorithms. Outcome measures are typing accuracy, typing speed and user experience.
Group III: Adaptive signal modelingExperimental Treatment1 Intervention
For this single case research design with alternating treatments without baseline, 5 participants with severe speech and physical impairment will complete copy spelling tasks with 3 signal adaptive modeling configurations. Outcome measures are typing accuracy, typing speed and user experience.
Group IV: Active querying techniquesExperimental Treatment1 Intervention
For this single case research design with alternating treatments without baseline, 5 control volunteers and 5 participants with severe speech and physical impairment who have AUC scores between 70-80% will complete copy spelling tasks with BCI-FIT active querying technique on and with BCI-FIT active querying technique off. Outcome measures are typing accuracy, typing speed and user experience.
