It was Dion’s first live performance since 2020 and comes roughly a year and a half after she announced that she had been diagnosed with stiff person syndrome.
According to the Johns Hopkins Medicine website, stiff person syndrome “is a rare autoimmune neurological disorder that most commonly causes muscle stiffness and painful spasms that come and go and can worsen over time.”
It most commonly develops in people aged between 40 and 50, the site says.
In April, while reflecting on her diagnosis, Dion told Vogue France that she was determined to get back onstage and that her goal was to see the Eiffel Tower in Paris again.
“The way I see it, I have two choices,” she said. “Either I train like an athlete and work super hard, or I switch off and it’s over, I stay at home, listen to my songs, stand in front of my mirror and sing to myself.”
“I’ve chosen to work with all my body and soul, from head to toe, with a medical team. I want to be the best I can be,” she added.
