​The ARC-EX System delivers programmed electrical stimulation through the skin to the spinal cord via electrodes placed on the back of the neck. This non-invasive approach requires no surgery, unlike other spinal cord stimulation devices. During therapy sessions, people with SCI use the device while performing functional tasks guided by trained rehabilitation specialists. Designed for clinical use, the system supports up to one hour of daily therapy and complements specialized rehabilitation exercises.

The Up-LIFT clinical study published in Nature Medicine showed that 90% of participants improved in upper limb strength or function, with 87% reporting enhanced quality of life. Additional benefits included reduced spasm frequency, improved sleep quality, and better upper body sensation. Regaining hand function is consistently rated as the highest treatment priority for people with spinal cord injuries, as it directly impacts independence in daily activities like eating, dressing, and personal care.
