(CNN) - More than 4,200 disabled athletes have gathered in London for the Paralympic Games, which opened this week. The Games are becoming more popular, as 2.5 million tickets were sold to Paralympic events.
But, there’s more to the competition than just the athletes going head-to-head on the playing field. The cutting-edge equipment they use is on display and in its own contest – a competition between companies.
Stephen Schulte owns ProCare, a prosthetics company in Buford, Georgia. He'll be closely watching how Jarryd Wallace runs in London.

The Paralympics serve as a type of ‘proving ground’ for prosthetics and other disabled sports equipment.
ProCare's VP of Business Development Steve Ehretsman says a good performance by Wallace can bring an uptick in business from other athletes, and all of whom arr disabled.
