A new spinal stimulation device has enabled three men paralyzed in motorcycle accidents to stroll outside with a walker within a few months.
The device stimulates nerves to send signals beyond the injury site to trigger leg movements.
For now, users have to select a desired movement on a tablet, which then routes the command to a pulse generator implanted in the abdomen that activates electrodes along the spine.
The process can take up to ten minutes.
A clinical trial for the device with up to 100 participants is scheduled for 2024.
