The ARCEX System is intended to deliver programmed, transcutaneous electrical spinal cord stimulation in conjunction with functional task practice in the clinic to improve hand sensation and strength in individuals between 18 and 75 years old that present with a chronic, non-progressive neurological deficit resulting from an incomplete spinal cord injury (C2-C8 inclusive). ONWARD ARCIM® and ARCBCI™, alone or in combination with a brain-computer interface (BCI), are investigational and not available for commercial use.
