About this study

Official title: Acute Electrocorticography (ECoG) Direct Brain Interface for Individuals With Upper Limb Paralysis

The purpose of this research study is to demonstrate that individuals with upper limb paralysis due to spinal cord injury, brachial plexus injury, amyotrophic lateral sclerosis and brain stem stroke can successfully achieve direct brain control of assistive devices using an electrocorticography (ECoG)-based brain computer interface system.

Read the detailed description

Brain-computer interface (BCI) technology aims to establish a direct link for transmitting information between the brain and external devices, offering a natural and rich control signal for prosthetic hands or functional electrical stimulators (FES) to re-animate paralyzed hands. This study focuses on an ECoG-based BCI system. ECoG measures brain activity using electrodes implanted on the surface of the brain. Each participant will undergo testing of the ECoG direct brain interface for up to 29 days. Participants will learn to control computer cursors, virtual reality environments, and assistive devices such as hand orthoses and functional electrical stimulators using neural activity recorded with the ECoG sensor.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Implantation of ECoG sensors on the brain surfaceDevice

    Also called brain-computer interface, neuroprosthetic

    One ECoG sensor will be implanted over the motor cortex of study participants

Study groups in NCT01393444
Study groupRoleWhat they receive
Direct Brain Interface UsersExperimentalAll participants enrolled in the study will undergo "Implantation of ECoG sensors on the brain surface" to record neural activity. There is no control group. There are no other arms.
Receives: Device: Implantation of ECoG sensors on the brain surface

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Able to Successfully Control of a Variety of External Devices Using Neural Data Recorded With ECoG

    Participants will attempt to control devices such as computer cursors, virtual reality environments and assistive devices such as hand orthoses or surface functional electrical stimulators using their brain activity recorded through ECoG.

    Measured: Up to 29 days of device implantation

Secondary outcomes (1)
  1. Number of Participants Able to Achieve Direct Brain Control of Assistive Devices Using an Electrocorticography (ECoG)-Based Brain-computer Interface System

    Participants will be asked to perform, attempt, or imagine performing motor tasks while their brain activity is recorded in order to observe the changes in neural activity during each task.

    Measured: Up to 29 days of device implantation

Questions about this trial

What is this clinical trial studying?

A study testing Implantation of ECoG sensors on the brain surface in people with Tetraplegia and Spinal Cord Injury, run by University of Pittsburgh at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Dec 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Able to Successfully Control of a Variety of External Devices Using Neural Data Recorded With ECoG (time frame: Up to 29 days of device implantation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01393444, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Dec 2016.
