A great example is Steven Storey, who was diagnosed with multiple sclerosis in 2013 and within a year his life was turned upside down.
As a full-fledged marathon runner, he was confined to a wheelchair, losing much of his sense of body movement.
He said that everything happened in a flash. "I got to the point where I needed care 24 hours a day. I do not have the ability to hold even the spoon so that I can eat like a normal person ".
His life, however, changed rapidly when he decided to try the new treatment of Sheffield doctors, as a result of which he moved his toes. Four months later, he was able to stand on his feet again.
However, this revolutionary new treatment gave Steven and other sufferers hope that they would be able to walk again.
