Sensorimotor Rhythm Brain-Computer Interface Switch to Operate Assistive Technology

Phase 1

Terminated

• Conditions: Healthy
• Interventions: Device: Brain Computer Interface Switch

• Registration Number: NCT01117727
• Lead Sponsor: University of Michigan

Brief Summary

The purpose of this research is to develop tools to help people who are paralyzed. These tools are called brain-computer interfaces (BCIs). BCIs would allow a person to use brain signals to operate technology. Specifically this project's goal is to design a BCI to operate a switch.

Detailed Description

The investigators want to make a BCI that can be used to operate commercially available technologies for communication, environmental control or computer access. The BCI would replace a switch to let people operate these technologies without moving. However, investigators need people to test the BCI so they can determine how effective it is in replacing a switch.

Primary Outcome Measures

Name	Time	Method
Accuracy of Using the BCI as a Switch to Select From 4 Targets Using Scanning	8 sessions over 2 months	Average accuracy for selecting one of 4 targets with a switch operated by a brain-computer interface controlled by power in the sensorimotor rhythms. The 8 sessions were conducted over a 2 month period. Accuracy was calculated as the percentage of trials in which the target was correctly selected. Trials for all sessions were combined to create the overall average. Therefore, there is no standard deviation. .
