Dancing is one of the pleasures of life, and there’s no reason why people with a disability shouldn’t enjoy it like any other. Wheelchair dancing even has international contests.
In the case of amputees, those missing an arm do not face specific challenges when it comes to dancing. Leg amputees obviously do. The pretty large amount of videos available on internet however shows that it’s not stopping them, and in some cases impressively so.
Most of all though, I find these videos an expression of fun in life, and of not letting an amputation be in the way of it.
Videos of dancing amputees can be found here.
