The actor that played Hercules (on the TV show). Kevin Sorbo. He wrote a book in which he mentioned it. He even ended up with a stroke which he attributed to his chiro, though I'm not sure it wasn't a blood clot from his ATOS. IIRC he had an interesting procedure where his subclavian artery was wrapped in a metal coil for protection. Obviously the MDs thought there was something going on there if they were willing to do that.

The Hanson guy is a guitarist and passed out on stage. I used to play guitar myself and wonder if it contributed (though playing by itself would not cause TOS without other factors involved).
