About this study

Official title: Validation of a Brain-Computer Interface for Neurorehabilitation With a Randomized Controlled Trial (Validación de Una Interfaz Cerebro-Computadora Para Rehabilitación Neurológica Por Medio de un Ensayo Clínico Controlado y Aleatorizado)

The study's main goal is to determine if clinical and physiological effects of a brain-computer interface intervention for the neurorehabilitation of stroke patients' upper limb are greater than the effects of a sham robotic feedback. For this purpose a randomized controlled trial will be performed to compare somatosensory sham robotic feedback with the same somatosensory feedback controlled with the brain-computer interface output.

Being tested
Brain-Computer Interface, Sham Brain-Computer Interface
Keywords
brain-computer interface, robotic orthosis, hemiparesis, motor rehabilitation
Medical subject headings
Ischemic Stroke, Stroke, Paresis

What participants receive

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

  • Brain-Computer InterfaceDevice

    Passive hand movement will be provided to patients' paralyzed hand by means of a robotic hand orthosis that will be activated by the brain-computer interface based on hand movement intention.

  • Sham Brain-Computer InterfaceDevice

    Passive hand movement will be provided to patients' paralyzed hand by means of a robotic hand orthosis which activation will be independent of the output of the brain-computer interface based on hand movement intention.

What is being measured

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

  1. Mean change from baseline in upper limb motor function on the Fugl-Meyer Assessment for the Upper Extremity

    Analysis of changes on the Fugl-Meyer Assessment for the Upper Extremity will reveal if there is a clinical significant sensorimotor function compared to baseline

    Measured: At enrollment, 3 weeks after the intervention onset, 6 weeks after the intervention onset, and 24 weeks after the intervention onset

  2. Mean change from baseline in upper limb motor function on the Action Research Arm Test

    Analysis of changes on the Action Research Arm Test will reveal if there is a clinical significant motor function compared to baseline

    Measured: At enrollment, 3 weeks after the intervention onset, 6 weeks after the intervention onset, and 24 weeks after the intervention onset

Secondary outcomes (3)
  1. Mean change from baseline in cortical activity measured with Functional Magnetic Resonance Imaging

    Blood-oxygen-level-dependent imaging will be analyzed to assess if there are changes in cortical activity compared to baseline.

    Measured: At enrollment, 3 weeks after the intervention onset, 6 weeks after the intervention onset, and 24 weeks after the intervention onset

  2. Mean change from baseline in corticospinal excitability measured with Transcranial Magnetic Stimulation

    Motor Evoked Potentials parameters will reveal if there are changes of corticospinal excitability in both hemibodies compared to baseline

    Measured: At enrollment, 3 weeks after the intervention onset, 6 weeks after the intervention onset, and 24 weeks after the intervention onset

  3. Mean change from baseline in grip strength measured with a dynamometer

    Analysis of hand strength measurements will reveal if there were changes compared to baseline

    Measured: At enrollment, 3 weeks after the intervention onset, 6 weeks after the intervention onset, and 24 weeks after the intervention onset

Questions about this trial

What is this clinical trial studying?

A study testing Brain-Computer Interface in people with Stroke, Ischemic and Stroke, run by Instituto Nacional de Rehabilitacion at 1 site in Mexico.

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 5 inclusion and 6 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 Jul 2024. 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 Mexico. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Mean change from baseline in upper limb motor function on the Fugl-Meyer Assessment for the Upper Extremity (time frame: At enrollment, 3 weeks after the intervention onset, 6 weeks after the intervention onset, and 24 weeks after the intervention onset). The study lists 2 primary outcomes in all. 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 NCT04724824, which also lists 2 linked publications.

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 Jul 2024.
