Overview
The study will investigate the use of motor intention-based cortical signals to trigger epidural spinal cord stimulation (ESCS) with individuals with SCI. Motor intention of UL tasks will be decoded using brain-computer interface (BCI) system based on cortical signals recorded using an Electroencephalographic (EEG) system or using their intracranially implanted devices Electrocorticographic (ECoG).
Interventions
- Procedure Epidural Spinal Cord Stimulation
This will be a one time surgery lasting no more than 2 hours where ESCS electrodes will be connected to an external stimulator approved for human research. Stimulation intensity and parameters will be configured before each session for optimal upper extremity motor function. The ESCS approach will include surgical implantation of temporarily placed leads in the cervical epidural space and connection cables tunneled percutaneously through the skin for \<30 days - Device Electrocorticographic
Neural activity during upper and/or lower extremity tasks will be recorded to characterize the changes that occur in the signals before, during, and after task performance. Observed characteristics of neural signals that are related to the initiation, continuation, or termination of movement will be used to derive control signals that can trigger or enable assistive devices. - Device Electroencephalographic
