COMMAND Early Feasibility Study: Implantable BCI to Control a Digital Device for People With Paralysis

Not Applicable

Active, not recruiting

• Conditions: Paralysis; Stroke; Muscular Dystrophies; Stroke Brainstem; Paralysis; Stroke, Lacunar; Tetraplegic; Paralysis; Neurologic Disorder; Spinal Muscular Atrophy; Spinal Cord Injuries; Cervical Spinal Cord Injury
• Interventions: Device: Motor Neuroprosthesis (MNP)

• Registration Number: NCT05035823
• Lead Sponsor: Synchron Medical, Inc.

Brief Summary

The Synchron motor neuroprosthesis (MNP) is intended to be used in subjects with severe motor impairment, unresponsive to medical or rehabilitative therapy and a persistent functioning motor cortex. The purpose of this research is to evaluate safety and feasibility.

The MNP is a type of implantable brain computer interface which bypasses dysfunctional motor neurons. The device is designed to restore the transmission of neural signal from the cerebral cortex utilized for neuromuscular control of digital devices, resulting in a successful execution of non-mechanical digital commands.
