Answer to Question 1
The C-Leg (computerized leg) is a lower leg prosthesis. It includes a prosthetic knee and shin system controlled by a microprocessor. It is made of lightweight carbon fiber and gets its power from a rechargeable battery. With a traditional prosthesis, the user has to think about each step. But the C-Leg analyzes gait 50 times per second; it anticipates movement and thus thinks for the patient. It is supposed to adjust to uneven ground by itself, but results from studies are mixed. It requires less energy for walking at speeds slower or faster than usual, but not at the walker's usual speed; the user does not have to think about changing walking speed. By 2011, more than 30,000 people were using the C-Leg. It can now be set by the user for a particular activity, such as bicycle riding.
