One night in 1999, a rash of frightening sensations hit Paul Titus all at once.
His left arm went numb. His left eye began twitching. He couldn’t speak without slurring.
Unaware what the symptoms meant, he was slow to call for help. When his ischemic stroke was finally over, he was paralyzed on his left side and for 14 years he needed a leg brace and cane just to stay upright.
One morning last week, Titus smiled as he loped along on a treadmill in a makeshift gym. A high-tech, brace-like device wrapped his left ankle, monitoring his gait 200 times per second and supplying energy boosts as needed.
“I think I’m [finally] getting close to getting rid of my cane,” he said, huffing as he went.
