Microelectrode Brain-Machine Interface for Individuals With Tetraplegia

Individuals with tetraplegia (paralysis caused by illness or injury that results in partial
or total loss of use of the arms and legs) have intact brain function but are unable to move
due to injury or disease affecting the spinal cord, nerves or muscles. Brain-machine
interface (BMI) technology is based on the finding that with intact brain function, neural
signals are generated even though they are not sent to the arms, hands and legs. By
implanting electrodes in the brain, individuals can be trained to send neural signals which
are interpreted by a computer and translated to movement which can then be used to control a
variety of devices or computer displays.

Inclusion Criteria:

brainstem or spinal stroke

- At least 1 year post-injury

- Live within 1 hour of the University of Pittsburgh and be willing to travel to the
University of Pittsburgh once per week for BMI training

- Additional inclusion criteria must also be reviewed

Exclusion Criteria:

- Certain implanted devices

- Presence of other serious disease or disorder that could affect ability to participate
in this study

- Individuals who are immunosuppressed or who have conditions that typically result in
immunocompromise

- Additional exclusion criteria must also be reviewed
