(Undated) — A paralyzed man can now walk by himself because of a combination of devices. Researchers in Switzerland published a study in the journal, Nature, describing implants that serve as a so-called “digital bridge” between Gert-Jan Oskam’s brain and spinal cord. It bypasses the 40-year-old’s injured sections and allows him to stand, walk, and take steps with help from a walker. Researchers say their work has limitations, but are hoping further advances make treatment more accessible.
