Doctors in the US state of Minnesota implanted a remote-controlled electrode in the patient’s back to stimulate surviving nerves in his spinal cord.
Thanks to the groundbreaking surgery, Jered Chinnock, from Tomah, Wisconsin, was able to stand up and walk just over 100 metres – the length of an American football – while pushing a front-wheeled walker.
It was the first time Mr Chinnock had walked by himself since his accident on the slopes five years ago.
“It’s very exciting, but still very early in the research stage,” said neurosurgeon Dr Kendall Lee, who co-led the team from the Mayo Clinic in Rochester.
“The reason why this is important is because the patient’s own mind, thought, was able to drive movement in his legs. Just as important is that we were able to get him to stand independently and take his own steps.”
Mr Chinnock said: “The walking side of it isn’t something where I just leave my wheelchair behind and away I go.”
But the Wisconsin man said he was hopeful that he might one day be able to “leave the wheelchair behind, even if it is to walk to the refrigerator.”
Dr Lee explained that as soon as the remote-controlled electrode was turned off, Mr Chinnock became paralysed again.
The innovative technique used by the Mayo Clinic team, which was reported in the journal Nature Medicine, involved inserting an electrode in the epidural space – the fat-filled hollow region surrounding the spinal cord.
