What’s exciting to me about this latest study is that the tech gave the participants skills they could use beyond the lab. And because the stimulator is external, it is likely to be more accessible and vastly cheaper. Yes, the newly enabled movements are small, but if you listen to the palpable excitement of one study participant as he demonstrates how he can move a small ball into a cup, you’ll appreciate that incremental gains are far from insignificant. That’s according to Melanie Reid, one of the participants in the latest trial, who spoke at a press conference last week. “There [are] no miracles in spinal injury, but tiny gains can be life-changing.”

In 2017, we hailed as a breakthrough technology electronic interfaces designed to reverse paralysis by reconnecting the brain and body. Antonio Regalado has the story

An implanted stimulator changed John Mumford’s life, allowing him to once again grasp objects after a spinal cord injury left him paralyzed. But when the company that made the device folded, Mumford was left with few options for keeping the device running. “Limp limbs can be reanimated by technology, but they can be quieted again by basic market economics,” wrote Brian Bergstein in 2015. 

In 2014, Courtney Humphries covered some of the rat research that laid the foundation for the technological developments that have allowed paralyzed people to walk.
