[Voiceover] Just before we jump into the movement-related signs and symptoms of Parkinson's disease, let's remind ourselves of what Parkinson's disease is. And that's a progressive brain disease. And this progressive disease, it ends up causing a reduction in the amount of a signalling chemical called dopamine. And when dopamine levels are lowered, what we really see are a bunch of problems with movement. So there are four main movement signs that we talk about when we're talking about Parkinson's disease. And we call them the main signs because they're usually the ones that we look for if someone actually has the disease. Not everyone with Parkinson's disease will develop all of these signs, but most people will at some point in the disease. And as the disease worsens over the years that the person has it, because remember, it's a progressive disease, these signs and symptoms usually worsen as well. The first main sign that we'll talk about is a tremor. And this tremor usually starts off in the hand or maybe in the finger. A tremor is involuntary shaking. ![]() ![]() And it actually happens because of lots and lots of relaxations and contractions in our muscles. You've probably noticed before that your hands can get a little shaky when you do certain things, maybe doing something like threading a needle. People are always making fun of me for having rips in my jeans, so I'm always patching them up, and I find that my hands get super-shaky when I'm threading a needle. Or maybe you've noticed it when you've done something like putting eye drops in your eyes. But the kind of tremor that someone with Parkinson's disease has, it's a lot worse than this. It's more frequent, and it's more debilitating. And we actually have a name for it. It's a particular kind of tremor called a resting tremor. A resting tremor happens when the body part is as it sounds, at rest.

So a good way to think about when a tremor would and wouldn't be around, is to imagine that you're about to go and grab a pen. If you had a resting tremor, your hand would be shaking before you went to grab for the pen, when it was just resting on the table. And this is because the hand would've been at rest. You wouldn't have been using it. But once you actually started to move your hand, your hand and the muscles in your hand wouldn't be at rest anymore, you'd be using them. And so the tremor would actually stop. So this sounds okay, you may be thinking, 'Okay, I'll just make sure I'm always moving my hand.' But it's not that easy. For a lot of people with Parkinson's disease, they actually still have trouble writing because the tremor can return again once they've finished grabbing the pen, and they're just holding their hand ready to write. So resting tremors are just one of the types of tremors that are out there, and there are lots of other different types that you may see in different conditions or even in just normal healthy people. But it's these resting tremors that are the kind that we see in someone with Parkinson's disease. The next main movement sign that we'll talk about is rigidity. Rigidity basically feels like really, really stiff muscles. When someone with rigidity goes to bend their arm, say they were gonna pick up some food from their plate and put it in their mouth, the movement between the plate and their mouth wouldn't be one smooth movement like it normally is. Instead, it's kind of like that movement happens in a few jerky movements, rather than that one smooth movement. We actually have a name for this series of jerky movements as someone with Parkinson's disease has. And it's called cogwheel rigidity. We call it cogwheel rigidity because this movement, in this case, bending the arm, it kind of looks like cogwheels moving together in that clunky sort of way. You know, like the cogwheels that you would see in a grandfather clock, for example. Erroll garner transcriptions pdf converter. This rigidity, this feeling of stiffness that causes these clunky movements, it's not just a feeling for the person with Parkinson's disease.
