Stumble Detection in Prosthetic Limbs

Because all amputees come from wars? Because only war amputees can benefit form new technology/techniques? Because there's a clear and achievable way to end wars without diving into the realm of fantasy, or ignoring coexisting problems? Is the better path to go back to how it was, where the government ignored amputees from wars? I think you need to take a look at the whole picture.

Because all amputees come from wars? ? What about amputees from accidents such as from vehicle crashes?

I thought the point of this was to develop a system that detects stumbling? How do you run tests using a subject that never stumbles?
