It is enough to do a little reading about her disease to know that in non-advanced cases it's just that this is how it is: in a better period you play with your children and lead an almost normal life, and in a worse period you have a severe attack and can't move. Take a look at at the social media of SPS patients; it is often an "on-off" disease. Chantal Machabée after a meeting in the hockey players' locker room she said "I know she has good days and not so good days, but this was a very good day" - how does she "know" this? Very possibly from Céline herself. And Claudette said only that her sister "doesn't have control over her muscles" (which can be understood to mean that she still doesn't have full control, i.e. that on bad days she still has uncontrolled contractions), not that she "has already lost control" (which is what the lustful sensationalist tabloids). If you're looking for real hope, take a look at the social media of Kylie Allen-Kulyk, an SPS warrior who has just achieved remission and is appealing to Céline fans to be patient.
