Figuratively and literally! AlterG was graciously mentioned in this year’s NASA SpinOff book. This book features innovative technologies from NASA’s space and aeronautics program that transfer the benefits of NASA technology to many sectors of our society. If you didn’t know already, AlterG’s “differential air pressure” technology was originally developed by NASA scientists to help astronauts exercise in space. Here is the article on the evolution of the technology from a tool for astronaut training in space, to a tool for rehabilitation and athletic training on Earth.
