A team of neuroscientists and neurosurgeons have re-established the communication between the brain and spinal cord with a wireless digital bridge, allowing a paralyzed person to walk again naturally.

The team implanted WIMAGINE® devices above the region of the brain that is responsible for controlling leg movements. These devices allow decode the electrical signals generated by the brain when a person thinks about walking. They also positioned a neurostimulator connected to an electrode array over the region of the spinal cord that controls leg movement.

Using algorithms based on adaptive artificial intelligence methods, movement intentions are decoded in real time from brain recordings.

Researchers were able to quantify remarkable improvements in the patient’s sensory perceptions and motor skills, even when the digital bridge was switched off. This digital repair of the spinal cord suggests that new nerve connections have developed.
