WEBVTT 00:00:00.218 --> 00:00:06.400 [intro piano music] 00:00:06.400 --> 00:00:09.029 Hi everyone, good morning. 00:00:09.029 --> 00:00:11.683 Welcome back to the OTmiri channel. 00:00:11.683 --> 00:00:15.441 If you're new here and we haven't met, my name is Miri. 00:00:15.441 --> 00:00:17.921 I'm a licensed occupational therapist 00:00:17.921 --> 00:00:21.455 and in today's video, I'll be talking to you guys about apraxia, 00:00:21.455 --> 00:00:23.578 specifically the difference between 00:00:23.578 --> 00:00:26.577 ideational and ideomotor apraxia. 00:00:26.577 --> 00:00:30.499 But before I get started, I just want to say congratulations 00:00:30.499 --> 00:00:32.280 to all of you who've found out 00:00:32.280 --> 00:00:35.534 that you passed the NBCOT exam this morning. 00:00:35.534 --> 00:00:39.218 I woke up so happy to all of your messages 00:00:39.218 --> 00:00:41.617 and thoughtful, sweet notes, 00:00:41.617 --> 00:00:46.284 whether on Instagram or on Facebook or here on this channel. 00:00:46.284 --> 00:00:49.815 I want you guys to know that it makes such a big difference uh, 00:00:49.815 --> 00:00:51.596 when you guys share the news with me 00:00:51.596 --> 00:00:55.976 and to know that, um, I was able to share this journey with you 00:00:55.976 --> 00:00:57.448 leading to your success. 00:00:57.448 --> 00:01:03.389 It uh, gives me such a great sense of satisfaction and pride for you 00:01:03.389 --> 00:01:05.962 and it motivates me to keep going. 00:01:05.962 --> 00:01:09.341 So much so that this is the first thing that I'm doing in the morning. 00:01:09.341 --> 00:01:12.117 I haven't even showered. I'm still in my pajamas, 00:01:12.117 --> 00:01:15.042 which I guess making a video in my pajamas 00:01:15.042 --> 00:01:17.808 is not my first time so you guys are probably used to it, 00:01:17.808 --> 00:01:19.807 but thank you, guys. 00:01:19.807 --> 00:01:24.924 Um, I, I will be celebrating in spirit with you today. 00:01:24.924 --> 00:01:28.273 Um, but let's get started. Apraxia. 00:01:28.273 --> 00:01:30.889 Now if you're preparing uh, for the exam 00:01:30.889 --> 00:01:33.007 and you're studying this content area, 00:01:33.007 --> 00:01:35.889 you might find yourself feeling confused 00:01:35.889 --> 00:01:38.424 or frustrated at times. I know I was. 00:01:38.424 --> 00:01:40.707 Because, depending on the literature, 00:01:40.707 --> 00:01:43.393 the authors, or even the country 00:01:43.393 --> 00:01:46.607 where these articles are written, or textbooks, 00:01:46.607 --> 00:01:50.173 you'll come across a wide range of terminologies, 00:01:50.173 --> 00:01:53.223 ranging from oculomotor apraxia, 00:01:53.223 --> 00:01:55.206 dressing, constructional, 00:01:55.206 --> 00:01:58.327 limb apraxia, there's also limb kinetic apraxia, 00:01:58.327 --> 00:02:00.023 and the list goes on and on. 00:02:00.023 --> 00:02:01.785 And the way these are classified 00:02:01.785 --> 00:02:04.291 are not always universally accepted, 00:02:04.291 --> 00:02:06.511 which makes it that much more challenging. 00:02:06.511 --> 00:02:08.689 So in this video today, and for the purposes 00:02:08.689 --> 00:02:10.882 of making it less overwhelming for you guys, 00:02:10.882 --> 00:02:13.714 I am going to talk about two general categories 00:02:13.714 --> 00:02:17.014 that you'll see most often in the rehabilitation literature 00:02:17.014 --> 00:02:19.114 as well as in your clinical setting, 00:02:19.114 --> 00:02:23.564 which are the ideational apraxia and ideomotor apraxia. 00:02:23.564 --> 00:02:28.142 So let's first get started by defining what apraxia is. 00:02:28.780 --> 00:02:32.347 It's basically a dysfunction or difficulty 00:02:32.347 --> 00:02:37.296 in execution of a skilled or purposeful activity 00:02:37.296 --> 00:02:40.163 that cannot be attributed to or explained 00:02:40.163 --> 00:02:44.479 by sensorimotor or cognitive comprehension deficits. 00:02:44.479 --> 00:02:47.030 So in other words, put another way, 00:02:47.030 --> 00:02:51.979 apraxia can occur even in the absence of weakness, 00:02:51.979 --> 00:02:54.881 spasticity, motor or sensory loss, 00:02:54.881 --> 00:02:57.729 memory or comprehension or cognitive deficits. 00:02:57.729 --> 00:02:59.280 Interesting, right? 00:02:59.280 --> 00:03:01.979 And it's typically lateralized to the left hemisphere, 00:03:01.979 --> 00:03:05.929 meaning it's due to a damage to the left hemisphere of the brain. 00:03:05.929 --> 00:03:10.280 And patients are oftentimes unaware of these deficits, 00:03:10.280 --> 00:03:13.362 which makes treatment that much more challenging. 00:03:13.362 --> 00:03:16.500 Now to really understand apraxia, 00:03:16.500 --> 00:03:19.595 it's helpful to know what the praxis system is. 00:03:19.595 --> 00:03:22.363 And I'm going to just talk about it very briefly. 00:03:22.363 --> 00:03:26.544 And a lot of the information that I'm talking about today 00:03:26.544 --> 00:03:28.547 is cited from Dr. Glen Dillon's work, 00:03:28.547 --> 00:03:30.253 and he's a fantastic resource 00:03:30.253 --> 00:03:32.911 so I'll list his books in the video description. 00:03:32.911 --> 00:03:35.611 But basically he talks about the praxis system 00:03:35.611 --> 00:03:37.883 as a two step process 00:03:37.883 --> 00:03:41.611 that results in the execution of a purposeful activity. 00:03:41.611 --> 00:03:45.678 The first step being ideation, or conceptualization, 00:03:45.678 --> 00:03:47.960 so it's having the idea or the right idea 00:03:47.960 --> 00:03:50.429 about the task and what needs to be done. 00:03:50.429 --> 00:03:52.776 And then the second step is production, 00:03:52.776 --> 00:03:55.695 so this is the actual execution of that task. 00:03:55.695 --> 00:04:00.812 And together, that results in execution of a purposeful activity. 00:04:00.812 --> 00:04:03.012 And when there is a breakdown 00:04:03.012 --> 00:04:06.561 in either one of those steps in the praxis system, 00:04:06.561 --> 00:04:08.245 you have apraxia, 00:04:08.245 --> 00:04:13.594 inability to perform these purposeful movements and tasks, okay. 00:04:13.594 --> 00:04:15.795 So now that you know what apraxia is, 00:04:15.795 --> 00:04:17.461 let's get into a little more detail 00:04:17.461 --> 00:04:20.160 and talk about ideational apraxia, 00:04:20.160 --> 00:04:24.430 which is referring to the breakdown in the ideation component. 00:04:24.430 --> 00:04:27.378 And so the patient with ideational apraxia 00:04:27.378 --> 00:04:29.410 will have no idea 00:04:29.410 --> 00:04:32.427 or have, don't have the right idea 00:04:32.427 --> 00:04:35.810 about what needs to be done with the task. 00:04:35.810 --> 00:04:40.580 And this includes not understanding the purpose of a tool or an object. 00:04:40.580 --> 00:04:44.113 So a classic example, and you may have seen this many times 00:04:44.113 --> 00:04:46.147 if you're in my Facebook study group 00:04:46.147 --> 00:04:48.597 or on my Instagram page, I also have this, 00:04:48.597 --> 00:04:51.349 um, is a photo of Ariel. [Chuckles] 00:04:51.349 --> 00:04:52.798 Not a surprise, right? 00:04:52.798 --> 00:04:54.057 My favorite character. 00:04:54.057 --> 00:04:55.996 I know I talk about her all the time. 00:04:55.996 --> 00:04:59.160 But you have to remember that scene in The Little Mermaid 00:04:59.160 --> 00:05:02.993 where she's sitting across the dining table hall with Prince Eric 00:05:02.993 --> 00:05:05.125 and she sees a fork and enthusiastically 00:05:05.125 --> 00:05:07.726 and unabashedly, she takes it up to her hair 00:05:07.726 --> 00:05:10.042 and she starts brushing her hair with the fork. 00:05:10.042 --> 00:05:13.675 This is a really good example of ideational apraxia, 00:05:13.675 --> 00:05:16.743 inability to use the tool appropriately, 00:05:16.743 --> 00:05:18.592 because she has lost the sense, 00:05:18.592 --> 00:05:22.459 has no idea what the purpose of the object is, 00:05:22.459 --> 00:05:24.725 and so she brushes her hair with a fork. 00:05:24.725 --> 00:05:27.293 In the clinical setting, you might see this 00:05:27.293 --> 00:05:31.659 being played out with a patient trying to write with a spoon 00:05:31.659 --> 00:05:37.659 or trying to brush their teeth with a comb, okay. 00:05:37.659 --> 00:05:40.475 Another component of ideational apraxia 00:05:40.475 --> 00:05:44.407 can be seen when the patient tries to engage in tasks 00:05:44.407 --> 00:05:46.059 that require multi steps. 00:05:46.059 --> 00:05:48.422 So sequencing is really difficult 00:05:48.422 --> 00:05:50.688 because patients don't have an idea 00:05:50.688 --> 00:05:53.821 of the demands of the task, okay. 00:05:53.821 --> 00:05:56.121 So again, idea comes into play here. 00:05:56.121 --> 00:05:59.787 And so um, think about a patient 00:05:59.787 --> 00:06:03.254 trying to uh, put on a shirt, 00:06:03.254 --> 00:06:07.253 but instead of putting their arms through the sleeve, 00:06:07.253 --> 00:06:10.454 they'll try to put their legs in instead, okay. 00:06:10.454 --> 00:06:14.222 Or um, they might try to wear socks over their shoes, 00:06:14.222 --> 00:06:16.727 so they've forgotten the steps and the sequence 00:06:16.727 --> 00:06:18.832 in which these activities occur. 00:06:18.832 --> 00:06:22.101 So uh, ideational apraxia is pretty straightforward. 00:06:22.101 --> 00:06:25.452 You just have to remember the word "idea" in ideational 00:06:25.452 --> 00:06:28.884 and understand that the patient with ideational apraxia 00:06:28.884 --> 00:06:33.908 has no idea what the task uh, requires, 00:06:33.908 --> 00:06:35.802 so they don't know how to use the object, 00:06:35.802 --> 00:06:37.293 they don't know how to, 00:06:37.293 --> 00:06:39.976 how the objects work in relation to each other, 00:06:39.976 --> 00:06:42.353 and they don't understand, they don't have an idea 00:06:42.353 --> 00:06:45.160 of the demands of the task, okay. 00:06:45.160 --> 00:06:48.758 Now contrast that with um, 00:06:48.758 --> 00:06:50.493 ideomotor apraxia. 00:06:50.493 --> 00:06:53.668 This is also known as, and used synonymously with, 00:06:53.668 --> 00:06:55.875 motor apraxia. 00:06:55.875 --> 00:06:58.543 And unlike ideational apraxia 00:06:58.543 --> 00:07:02.150 where patients have no idea what the demand of the task is 00:07:02.150 --> 00:07:03.992 and how to use an object, 00:07:03.992 --> 00:07:05.786 in ideomotor apraxia, 00:07:05.786 --> 00:07:07.978 patients actually do have an idea. 00:07:07.978 --> 00:07:11.917 They have an understanding of what the task requires. 00:07:11.917 --> 00:07:16.284 Um, and given, and if their language is intact, 00:07:16.284 --> 00:07:18.832 they might even be able to verbalize to you 00:07:18.832 --> 00:07:22.185 what the task is that they have to perform. 00:07:22.185 --> 00:07:24.267 But in ideomotor apraxia, 00:07:24.267 --> 00:07:26.200 they have lost access 00:07:26.200 --> 00:07:29.401 to kinesthetic or kinetic memory 00:07:29.401 --> 00:07:31.031 related to that task, 00:07:31.031 --> 00:07:34.934 so they're no longer able to perform that task, okay. 00:07:34.934 --> 00:07:37.321 And so uh, this is really fascinating. 00:07:37.321 --> 00:07:39.857 Let me give you an example in a scenario. 00:07:39.857 --> 00:07:42.780 Uh, you see a patient, 00:07:43.961 --> 00:07:46.031 when you pass by a patient's hall, 00:07:46.031 --> 00:07:50.660 and you notice that he is brushing his hair with a comb, okay. 00:07:50.660 --> 00:07:54.144 20 minutes later, into the session, 00:07:54.144 --> 00:07:55.999 you ask him to brush his hair. 00:07:55.999 --> 00:07:58.342 You give him the verbal command and you say, 00:07:58.342 --> 00:08:01.843 "Can you show me how you brush your hair in the morning?" 00:08:01.843 --> 00:08:05.643 And although he was able to do it earlier in the morning, 00:08:05.643 --> 00:08:08.193 automatically, in context, 00:08:08.193 --> 00:08:12.009 he will no longer be able to do that upon verbal command, 00:08:12.009 --> 00:08:14.059 where if you try to ask him 00:08:14.059 --> 00:08:18.131 or have him mimic or imitate your movement 00:08:18.131 --> 00:08:20.750 and say, "Can you try to do this, brush your hair?", 00:08:20.750 --> 00:08:23.399 he won't, the patient won't be able to copy it. 00:08:23.399 --> 00:08:27.731 So, inability to perform a movement upon verbal command 00:08:27.731 --> 00:08:29.939 or mimic or imitate gestures. 00:08:29.939 --> 00:08:34.337 This is a classic indeomotor apraxia. 00:08:34.337 --> 00:08:37.387 Isn't the brain really fascinating?
