The first female to be fitted with a bionic arm is Claudia Mitchell of Ellicott City, Maryland, USA, who had lost her left arm at the shoulder following a motorcycle accident. Her bionic arm was designed by medics and engineers of the the Rehabilitation Institute of Chicago, USA, and allows Ms Mitchell to control parts of the limb by thought. Ms Mitchell revealed her arm at a press conference in Chicago, USA on 14 September 2006.
