 Not a dumb question. How do amputees actually control prosthetics? So I'm going to show you how mine works and then we're going to talk about actually a lot of different ways that amputees can control prosthetic limbs. So the way that I am able to walk on my prosthetic leg is just weight transfer. And there's actually a lot of movement in the carbon fiber pieces that make up my ankle. So as I bring my foot forward and transfer my weight, I'm engaging my quad muscles, my glute muscles, and transferring the weight over is what allows this to move. Now there are other prosthetics that rely on computerized parts. You'll probably see more of these with upper limb amputees where there are sensors built into the inside of a prosthetic and as someone fires nerves because the nerves still exist to move your fingers even after your fingers don't exist anymore. And as you engage those nerves or do a very specific kind of movement, your prosthetic response for amputees with above the amputations, you often have computerized knees that are adjusting based on the movement of your body for what kind of movement you are trying to accomplish. And there are ankles that are computerized as well. I've tried them before. I don't like them. It feels weird. It's not for me. And that's how we do it.
