THROW AGAIN….. with Speed!
THROW AGAIN….. with Control!
THROW AGAIN….. with your kids!

“For the first time in over forty years I’ve been able to instinctively throw a baseball at speeds over 50 mph and accurately to distances exceeding 35 meters, using a prosthesis…. and to my knowledge this has never, ever been accomplished in the entire history of prosthetics, it is a revolutionary achievement. It’s personally been very rewarding and exciting. I was a centerfielder as a youth, made the All-Stars in Little League and was proud of my strong arm and throwing capability, so when I lost my left hand in an auto accident at age 22, it was very traumatic to realize that I’d never be able to throw lefty again. I was wrong… Its amazing!”
– Bob Radocy, arm amputee, inventor and CEO of TRS Prosthetics
