Restoring High Dimensional Hand Function to Persons With Chronic High Tetraplegia

Completed · Not applicable

Conditions studied: Spinal Cord Injuries, Tetraplegia, Quadriplegia

In brief

This study is for people who have a paralyzed arm and hand from a spinal cord injury, who have also received a recording electrode array in the brain as part of the BrainGate study. The study will look at the ability of these participants to control different grasping patterns of the hand, both in virtual reality and in his/her actual hand. Movement of the participant's hand is controlled by a functional electrical stimulation (FES) system, which involves small electrodes implanted in the arm, shoulder and hand that use small electrical currents to activate the appropriate muscles.

Who can join

Age: any. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Cognitively intact (able to follow instructions)
• A spinal cord injury resulting in at least partial arm paralysis
• Participant in BrainGate2 clinical trial, having already received an intracortical array and demonstrated the ability to use the neural signals to control a cursor on a monitor.

You may not qualify if…

• Profound visual impairments
• Participant in BrainGate2 clinical trial with insufficient recordable neural signals (such that the researchers cannot decode a movement intention command signal)
