That ergot poisoning theory is pretty solid, honestly. The doc probably mentioned how the fungus messes with your brain, right? Makes people see things and twitch. Seen something similar once with bad mold in an old barn, whole different thing but people act weird when they breathe in the wrong stuff. Medieval grain storage was a gamble, so it tracks that a whole town could eat tainted bread and lose it. Still wild to think about hundreds of people just dancing until they dropped.

Gear can trick you into moving wrong since it hides the pain. Then your form goes bad without you even knowing.
