My partner and I were tasked with designing a solution to help children with upper limb amputation play on the monkey bars. At some point in time, every child with an upper limb amputation will ask their prosthetist if they can do the monkey bars, and the answer is always no. The main issue is that prosthetic sockets are great in compression but are not good in tension. To solve this problem, our solution inverts the motion required to play on the monkey bars and has the arm pointing down with a hook coming up out of the socket. We prototyped our solution using a hook that I made out of steel, two ski poles, and some wood. I could hang comfortably from the device and stay on the monkey bars statically. The dynamic movement of the prototype was promising and could be achieved after a few iterations.
