October 30, 2024 7:52 AM EDT Over 250,000 people in the U.S. alone live with spinal cord injuries. To help patients regain sensation and strength in their hands and arms, Onward Medical’s
ARC-EX therapy uses electrical stimulation—applied externally with electrodes—to effectively boost the brain’s signals. A study in _Nature_ showed that nine out of 10 patients using ARC-EX
recovered some strength or functionality; it also found that the treatment can be effective for patients who had injuries _decades_ earlier. “For most people with a spinal cord injury,
there’s some [brain signal] conduction making it through the block, but not enough for movement,” says Dave Marver, CEO of Onward. “This device serves as an amplifier.”
