  hi Alisha,
  
  It takes a little while for someone to get used to an artificial limb (hand or leg). The amputees usually have several training sessions with physiotherapists and prosthetists to make sure they are able to use it, they practice and they feel comfortable with it. It is similar to learning to walk again! Crazy, isn’t it?
