Hi Arturo,
thank you very much, your help is always precious.
Actually, we are in contact with several doctors and only one agreed in giving this health certificate. So, my daughter can continue in doing sport for this year. Our concern was about the potential risks that were exposed by some doctors (those who refused to issue the certificate), so we want to deepen this question and share these information with them in order to have similar certificates in the future with no problem or
The infos you mention are very useful to me and I'll bring them (article reference and abstract) to the doctors. I think they have access to these full articles, anyway if they should need, I'll contact you. Very useful to know that there are some of SCLS affected people who make even intense physical exercises.
Thank you again, Alessandro
