Symptoms of stiff person syndrome include muscle rigidity in the trunk and arms, often triggered by noise, touch and emotional distress. Celine's condition is characterised by muscle spasms.
People with stiff person syndrome suffer from frequent falls, because they lack defensive reflexes to save themselves.

What causes stiff person syndrome?
It's not known what causes the disorder, and it's often misdiagnosed as Parkinson’s disease, multiple sclerosis, fibromyalgia, psychosomatic illness, or anxiety and phobia.
Can you cure stiff person syndrome?
The disorder doesn't have a cure, though anti-anxiety drugs, muscle relaxants, and anti-convulsants. Pain relief can also improve symptoms.
Celine said that spasms caused by stiff person syndrome impact every aspect of her daily life. "They sometimes cause difficulties when I walk, and it's not allowing me to use my vocal cords to sing the way I am used to."
"I have a great team of doctors working alongside me to help me get better and I'm working hard with my sports medicine therapist every day to build back my strength and my ability to perform again but I have to admit it's been a struggle," Celine continued.
It was in October 2021 when Celine first revealed that her ill health meant she would be delaying her Las Vegas shows, and she's not taken to the stage since.
The much-loved superstar has had to tearfully cancel and postpone numerous tour dates, leaving both her and her fans devastated.
