Incomplete quadriplegic recovery may be entering a new era with advances in non-invasive spinal cord stimulation. The ONWARD ARC-EX™ System is an FDA-cleared external spinal cord stimulation device designed to support improvements in hand sensation, strength, and upper-limb function in certain adults living with chronic, incomplete cervical spinal cord injury (SCI).
ARC-EX is designed for adults ages 18–75 with chronic, incomplete cervical SCI involving neurological levels C2–C8. Rather than requiring an implant or surgery, the system delivers programmed electrical stimulation through electrodes placed on the skin over the neck while the person participates in rehabilitation.
ARC-EX Spinal Cord Stimulation
ARC-EX spinal cord stimulation – The effectiveness of ARC-EX Therapy was evaluated in the Up-LIFT pivotal trial, which included 65 participants with chronic incomplete tetraplegia across 14 spinal cord injury centers in the United States, Europe, and Canada. The results were published in Nature Medicine.
Several findings from the study are particularly encouraging for people interested in spinal cord injury hand recovery:
- The primary safety and effectiveness endpoints were met.
- 90% of participants improved upper-limb strength or function.
- Upper-extremity sensory scores improved significantly.
- 87% of participants reported improvements in quality of life.
- Improvements were observed in participants who were up to 34 years post-injury.
These findings highlight the potential of combining electrical spinal cord stimulation with structured rehabilitation to improve upper-extremity function in selected people with chronic, incomplete cervical SCI.
How Does ARC-EX Work?
ARC-EX uses controlled electrical pulses delivered through skin electrodes positioned on the neck. The stimulation is provided during rehabilitation exercises and is intended to help activate spinal cord neural pathways involved in movement and sensation.
For people searching for incomplete quadriplegic recovery, this technology represents an important development in non-invasive neurorehabilitation. However, results can vary between individuals, and ARC-EX is intended for a specific population with chronic, incomplete cervical SCI.
Important: ARC-EX Is Not a Cure
ARC-EX should not be considered a cure for spinal cord injury. It is a medical technology designed to assist rehabilitation and improve upper-limb function in eligible individuals. Anyone considering this therapy should review the scientific evidence and speak with an appropriately qualified spinal cord injury specialist.
