According to Sina Entertainment, foreign media reported that Celine Dion lost control of her muscles after battling stiff person syndrome. Her sister told the outlet: "It breaks my heart that she can't control her muscles and she's been working so hard."

The 55-year-old singer Celine Dion was diagnosed with Stiff Person Syndrome (SPS) in December last year and later announced the cancellation of her concert. She worked hard to fight against SPS, but unfortunately it backfired. After a year of hard struggle, Celine Dion's condition gradually worsened and she could no longer control her body muscles. She has been taken care of by her 74-year-old sister.

Stiff person syndrome is an incurable disease with a global incidence of only one in a million. When the disease occurs, patients will experience severe muscle pain all over the body. The muscles gradually harden and are accompanied by spasms until the patient loses the ability to move, so it is called "stiff person".
