i want to know how gene therapy can help all types of cystic fibrosis.and i also want to know what are some of the really bad cystic fibrosis diseases or diseases that are alike them.

I’m 20 and my girlfriend is 19. My girlfriend has Cystic Fibrosis and i invited her to stay over for a few days with me at my place. I was kind of surprised when she first told me about her disease. I know she has pretty low lung function and will have a lung transplant eventually. But how is the physiotherapy done and in what ways and how often? Do they usually do it on their own or do they often need someone to help them? Should I know how to do it with my girlfriend?
