Quad amputee Moshe runs for the very first time, thanks to state-of-the-art prosthetics). A 9-year-old quadruple amputee – the son of a Hasidic student who survived a bullet to the brain in the fatal 1994 Brooklyn Bridge shooting – has learned to run for the very first time thanks to a pair of brand new prosthetics. A broad smile plastered to his face, Moshe Sasokin joyfully bounds through the halls of Prosthetics in Motion, which fitted him with custom-made running blades, in video taken last month. Moshe was just 6 months old when he was diagnosed with a severe case of meningitis – leading doctors to amputate below his elbow and knee in order to save his life. In 2015, he first learned how to walk at age 6 after being fitted with his first pair of prosthetic legs.
