Restoring Speech With an Intracortical Neuroprosthesis for Post-Stroke Agrammatic Aphasia (BG-Aphasia-02) (BG-Aphasia-02)

November 4, 2026 updated by: Leigh R. Hochberg, MD, PhD.

Restoring Speech With an Intracortical Neuroprosthesis for Post-Stroke Agrammatic Aphasia

In this study, the investigators aim to continue the development of a brain-computer interface (BCI) to help restore speech for stroke survivors with agrammatic aphasia, a language disorder that affects the ability to speak.

Detailed Description

One in four adults will have a stroke in their lifetime. When the blood flow to the brain is blocked or reduced, brain cells get deprived of oxygen. This might impact language areas in the brain and lead to aphasia.

The goal of this project is to advance the methods by which people with aphasia can help develop and by using an intracortical brain-computer interface (iBCI) restore communication that may serve as a rehabilitation device.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sensor implant duration for at least one-year without any device-related Serious Adverse Events or explant
Time Frame: 1 year

To determine the safety of the Sensor and overall safety of the System. Participants will be considered a success for this safety measure if they are successfully implanted with the Sensor(s) and:

  1. the sensors are not explanted for safety reasons during the one-year post-implant evaluation period.
  2. there are no device-related Serious Adverse Events that result in death or permanently increased disability during the one-year post-implant evaluation period.
1 year
