 The rigidity, what do you mean? Oh, rigidity, loss of arm swing, standing up more dotically. You notice when he turns, it's kind of end block turning. It's not a quick turn. So that's one of the hallmarks of Parkinsonism is rigidity and bradykinesia, slow movement. And he has that hallmark, especially with the low voice that was a cold. Ophonia, a small monotone voice like this over time, is a hallmark of Parkinsonism. I could have diagnosed him from across the mall.
