Trial summary

Sensorimotor (also know as mu) rhythm based brain-computer interfaces (BCIs) are a tool for controlling electronic devices using only brain signals. Often, the computer software that analyzes mu-rhythm brain signals constantly adapts to the individual user's brain signals when the training target location is known. Read more about this study

About this study

Official title: Effect of Normalizer Adaptation on Accuracy in a Sensorimotor Based Brain-Computer Interface

Sensorimotor (also know as mu) rhythm based brain-computer interfaces (BCIs) are a tool for controlling electronic devices using only brain signals. Often, the computer software that analyzes mu-rhythm brain signals constantly adapts to the individual user's brain signals when the training target location is known. The investigators want the BCIs to be more universal, and not depend on knowing the target location. Therefore, the investigators will test the effect removing adaptation has on accuracy of using a mu-rhythm BCI.

Being tested
Brain computer Interface Mu (SMR) rhythm

What participants receive

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

  • Brain computer Interface Mu (SMR) rhythmOther

    Subjects will wear an EEG cap for 1-2 hours typical per session and use the brain computer interface to operate assistive technology. Subjects will be asked to participate in 10 sessions.

What is being measured

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

  1. Accuracy of a mu rhythm BCI using adaptation versus no adaptation.

    Accuracy with which subjects can select one of two targets after a 3-second time period. The accuracy for a run is calculated as the % of the trials in which the correct target is selected. The average accuracy will be calculated for each of the 10 usage sessions and changes over the sessions will be tracked.

    Measured: 10 times over 5 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Brain computer Interface Mu (SMR) rhythm in people with Healthy Volunteers, run by University of Michigan 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 3 inclusion and 5 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: stopped early, as of the sponsor's last update on 23 Jun 2014. 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?

The study was stopped early (reason given: Insufficient improvement in primary measures under either condition.). Results are not available in the source record.

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?

Accuracy of a mu rhythm BCI using adaptation versus no adaptation. (time frame: 10 times over 5 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Jun 2014.
