Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Brain Computer Interface-Epidural Spinal Cord Stimulation (BCI-ESCS)

Participants in this group will receive a onetime surgery to have the leads implanted temporarily for ESCS which will be triggered through the BCI system. The BCI-ESCS arms will include Upper limb (UL) therapist-guided training, with triggered through a BCI system during task practice. The BCI system will decode motor intention of Upper limb (UL) tasks from cortical signals recorded using EEG system or using their intracranially implanted devices (e.g., ECoG). Participants will perform UL daily activities (e.g., grasping, reaching) tailored to participants deficits. The therapist will facilitate task practice and progress therapy within and between session.

Subjects will be involved in the intervention for up to 2 months.

Group Type EXPERIMENTAL

Epidural Spinal Cord Stimulation

Intervention Type PROCEDURE

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

Electrocorticographic

Intervention Type DEVICE

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.

Electroencephalographic

Intervention Type DEVICE

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.
