It really just comes from the greek word for a wrong measurement. They have the map in their head and they drive all around but they always end up at the right spot.
TREMULOUS GRAPHICS OPTIONS DRIVER
So ataxia I like to say um if you think of a taxi cab driver uh sort of a memory trick here, they can get you to the same destination going hundreds of different routes. But it does help us differentiate the types of movements if you can distinguish what you see with a taxi and Demetria. Um We can really try and parse out what type of tremor it is based on how fast it is And then the last two I think um I don't really expect you to know the difference or as the neuro anatomy, why they're different. The frequency of movement really helps us distinguish several types, especially with tremors. Sometimes people call this coarse or fine, um they're big or small basically and then frequency is going to be how fast it happens. Um I'm sure you guys remember physics from forever ago, but it's just like our waves, right? So they have an amplitude and they have a frequency amplitude can be um it can be large, it can be small. So amplitude is really, you can think about the size of the movement that they're doing. And so there's really only four terms that I'm going to bring up today. Um I will caveat that for movements that sometimes it's really helpful to know the distinction and use the right terms because it really helps the neurologist who you're referring to to really understand what you're seeing. If you can convey yourself by describing what you see, then that usually is more important and more valuable than using the right terminology. Alright, when I am teaching the medical exam to residents and fellows, I usually highlight the fact that vocabulary is not so important. And then lastly, we'll touch on a couple conditions with non volitional movements. The second category is going to be functional abnormal movements and these are ones that um they sometimes get mistaken as volitional or they're doing it on purpose, but really they should be thought of more as non volitional movements, but they fall into the functional category. We're gonna talk about movements in main categories of volitional movements or intentional movements. So we're going to do three key things today. So I like this uh picture sort of just to introduce the topic of movements. And that's really true for a lot of patients that have abnormal movements because they sort of can be quite buy it and you know, providing the right diagnosis can be really liberating. It's by an artist called named Leonid Avramov. So without further ado we're going to talk about admiral movements today and um this picture on the side it just sort of I think encapsulates my my idea of movement and patients that are affected by abnormal movements. So if you have questions you're unsure of something please send them along. Um But as always we're happy to see anyone. Um or at least you'll learn something as far as who needs to come to neurology and who doesn't. Um My talk today hopefully will be interesting for most of you. Hello everyone and thank you for joining us today. With video examples to illustrate, she clarifies tics, tremors and other commonly seen motions provides a straightforward vocabulary and clarifies when something that looks alarming is actually cause for concern.
