Amy demonstrates extraordinary balance on her prosthetic legs. This type of balance requires a very strong core. It also demonstrates exceptional flexibility.

This move could cause a shoulder injury if performed incorrectly. There are also several moments during the dance where Amy bends backwards over Derek's arm. This could cause a possible back injury if done improperly. The last video I saw is really amazing. The dance takes place in India in one of their talent shows.

The only thing that worries me is that he will eventually suffer from overuse of his right leg and finish
