Researchers have identified neurons that promote the ability to walk in some people with lower body paralysis due to spinal cord injuries

gained the ability to walk after receiving prolonged electrical stimulation to the injured area of their spine. This led to researchers identifying neurons that may help to improve walking ability post-paralysis.in people with spinal cord injuries. In the latest discovery, electrical stimulation also accelerated walking recovery among people with spinal cord injuries who had enough functioning neurons in the affected area.

Over the next five months, they continued to receive this electrical stimulation, alongside guided physiotherapy sessions, up to five times a week. At the end of the study period, they could walk 50 metres in 6 minutes, on average. They then used a genetic tool, which could be controlled via light, to silence and reactivate the neurons linked to walking recovery. The rehabilitated mice could only walk when the neurons were switched on.
