Following her disability, she took up wheelchair table tennis, competing for Austria. She met Andreas Vevera while at Weißer Hof, and the two trained together in the sport. Both competed at the 2008 Summer Paralympics in Beijing, China, where Vevera won the gold medal in the men's individual class 1, while Mader finished fifth in women's individual class 3. Those roles were reversed at the 2012 Games in London, England, where Vevera was eliminated early. He then coached Mader as she won the silver medal in her class, following defeat by Sweden's Anna-Carin Ahlquist in the final.
