I found this article pretty interesting!
Three times a week, Vince Stankoski is lifted from his wheelchair onto a stationary bicycle. Electrodes are attached to three of his muscle groups, coaxing his paralyzed legs to pedal.
It is the highlight of his workout.
"I like that I can look down at my legs and still see muscles there," says the Allentown, Pa., man who lost the use of his legs after falling from a tree in 1998.
Apart from the bike, he also likes using the upper body weights, which come equipped with a seat that swivels away so he can move his wheelchair into position and lift.
Stankoski is one of the fortunate ones. He belongs to a gym specifically designed to accommodate people with disabilities...........
