Fox's pogo stick leg innovation by Hugh Westrup
Amputee inventor Terry Fox inspired a new prosthetic leg with a pogo stick style shaft and shock absorber. Designers Martel and Iler tested it on Grant Darby at McMaster, aiming to reduce impact and allow one step per step of the good leg. Weight is the main flaw, with aluminum or titanium options expected to cut weight and a marketable version priced around 3500 dollars within 12 to 18 months.
