What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a person with chronic paralysis from a spinal cord injury could control hand movements using only their thoughts. The participant, who already had a brain implant from the BrainGate study, used a computer to decode their intended grasp patterns. Those signals then triggered small electrical pulses in arm and hand muscles to produce actual hand movements. The goal was to see if this brain-computer interface could restore useful hand function.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Neuroport cortical recording array and functional electrical stimulation (FES) system
What this could lead to
If successful, this approach could help people with paralysis regain some hand function, improving independence in daily tasks like grasping objects.
What could go wrong
This was a very early study with only one participant, so results may not apply to others. The system requires brain surgery and implanted electrodes, which carry risks of infection or device failure.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

1 person

The number who actually took part.

Started

Jun 2018

Finished

Sep 2023

Lead sponsor

A government agency

The lead sponsor is a US federal agency other than the NIH.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Cognitively intact (able to follow instructions) * A spinal cord injury resulting in at least partial arm paralysis * Participant in BrainGate2 clinical trial, having already received an intracortical array and demonstrated the ability to use the neural signals to control a cursor on a monitor. Exclusion Criteria: * Profound visual impairments * Participant in BrainGate2 clinical trial with insufficient recordable neural signals (such that the researchers cannot decode a movement intention command signal)
