[intro piano music]

2
99:59:59,999 --> 99:59:59,999
Hi everyone, good morning.

3
99:59:59,999 --> 99:59:59,999
Welcome back to the OTmiri channel.

4
99:59:59,999 --> 99:59:59,999
If you're new here and we haven't met, my name is Miri.

5
99:59:59,999 --> 99:59:59,999
I'm a licensed occupational therapist

6
99:59:59,999 --> 99:59:59,999
and in today's video, I'll be talking to you guys about apraxia,

7
99:59:59,999 --> 99:59:59,999
specifically the difference between

8
99:59:59,999 --> 99:59:59,999
ideational and ideomotor apraxia.

9
99:59:59,999 --> 99:59:59,999
But before I get started, I just want to say congratulations

10
99:59:59,999 --> 99:59:59,999
to all of you who've found out

11
99:59:59,999 --> 99:59:59,999
that you passed the NBCOT exam this morning.

12
99:59:59,999 --> 99:59:59,999
I woke up so happy to all of your messages

13
99:59:59,999 --> 99:59:59,999
and thoughtful, sweet notes,

14
99:59:59,999 --> 99:59:59,999
whether on Instagram or on Facebook or here on this channel.

15
99:59:59,999 --> 99:59:59,999
I want you guys to know that it makes such a big difference uh,

16
99:59:59,999 --> 99:59:59,999
when you guys share the news with me

17
99:59:59,999 --> 99:59:59,999
and to know that um, I was able to share this journey with you

18
99:59:59,999 --> 99:59:59,999
leading to your success.

19
99:59:59,999 --> 99:59:59,999
It uh, gives me such a great sense of satisfaction and pride for you

20
99:59:59,999 --> 99:59:59,999
and it motivates me to keep going.

21
99:59:59,999 --> 99:59:59,999
So much so that this is the first thing that I'm doing in the morning.

22
99:59:59,999 --> 99:59:59,999
I haven't even showered. I'm still in my pajamas,

23
99:59:59,999 --> 99:59:59,999
which I guess making a video in my pajamas

24
99:59:59,999 --> 99:59:59,999
is not my first time so you guys are probably used to it,

25
99:59:59,999 --> 99:59:59,999
but thank you, guys.

26
99:59:59,999 --> 99:59:59,999
Um, I, I will be celebrating in spirit with you today.

27
99:59:59,999 --> 99:59:59,999
Um, but let's get started. Apraxia.

28
99:59:59,999 --> 99:59:59,999
Now if you're preparing uh, for the exam

29
99:59:59,999 --> 99:59:59,999
and you're studying this content area,

30
99:59:59,999 --> 99:59:59,999
you might find yourself feeling confused

31
99:59:59,999 --> 99:59:59,999
or frustrated at times. I know I was.

32
99:59:59,999 --> 99:59:59,999
Because, depending on the literature,

33
99:59:59,999 --> 99:59:59,999
the authors, or even the country

34
99:59:59,999 --> 99:59:59,999
where these articles are written, or textbooks,

35
99:59:59,999 --> 99:59:59,999
you'll come across a wide range of terminologies,

36
99:59:59,999 --> 99:59:59,999
ranging from oculomotor apraxia,

37
99:59:59,999 --> 99:59:59,999
dressing, constructional,

38
99:59:59,999 --> 99:59:59,999
limb apraxia, there's also limb kinetic apraxia,

39
99:59:59,999 --> 99:59:59,999
and the list goes on and on.

40
99:59:59,999 --> 99:59:59,999
And the way these are classified

41
99:59:59,999 --> 99:59:59,999
are not always universally accepted,

42
99:59:59,999 --> 99:59:59,999
which makes it that much more challenging.

43
99:59:59,999 --> 99:59:59,999
So in this video today, and for the purposes

44
99:59:59,999 --> 99:59:59,999
of making it less overwhelming for you guys,

45
99:59:59,999 --> 99:59:59,999
I am going to talk about two general categories

46
99:59:59,999 --> 99:59:59,999
that you'll see most often in the rehabilitation literature

47
99:59:59,999 --> 99:59:59,999
as well as in your clinical setting,

48
99:59:59,999 --> 99:59:59,999
which are the ideational apraxia and ideomotor apraxia.

49
99:59:59,999 --> 99:59:59,999
So let's first get started by defining what apraxia is.

50
99:59:59,999 --> 99:59:59,999
It's basically a dysfunction or difficulty

51
99:59:59,999 --> 99:59:59,999
in execution of a skilled or purposeful activity

52
99:59:59,999 --> 99:59:59,999
that cannot be attributed to or explained

53
99:59:59,999 --> 99:59:59,999
by sensorimotor or cognitive comprehension deficits.

54
99:59:59,999 --> 99:59:59,999
So in other words, put another way,

55
99:59:59,999 --> 99:59:59,999
apraxia can occur even in the absence of weakness,

56
99:59:59,999 --> 99:59:59,999
spasticity, motor or sensory loss,

57
99:59:59,999 --> 99:59:59,999
memory or comprehension or cognitive deficits.

58
99:59:59,999 --> 99:59:59,999
Interesting, right?

59
99:59:59,999 --> 99:59:59,999
And it's typically lateralized to the left hemisphere,

60
99:59:59,999 --> 99:59:59,999
meaning it's due to a damage to the left hemisphere of the brain.

61
99:59:59,999 --> 99:59:59,999
And patients are oftentimes unaware of these deficits,

62
99:59:59,999 --> 99:59:59,999
which makes treatment that much more challenging.

63
99:59:59,999 --> 99:59:59,999
Now to really understand apraxia,

64
99:59:59,999 --> 99:59:59,999
it's helpful to know what the praxis system is.

65
99:59:59,999 --> 99:59:59,999
And I'm going to just talk about it very briefly.

66
99:59:59,999 --> 99:59:59,999
And a lot of the information that I'm talking about today

67
99:59:59,999 --> 99:59:59,999
is cited from Dr. Glen Dillon's work,

68
99:59:59,999 --> 99:59:59,999
and he's a fantastic resource

69
99:59:59,999 --> 99:59:59,999
so I'll list his books in the video description.

70
99:59:59,999 --> 99:59:59,999
But basically he talks about the praxis system

71
99:59:59,999 --> 99:59:59,999
as a two step process

72
99:59:59,999 --> 99:59:59,999
that results in the execution of a purposeful activity.

73
99:59:59,999 --> 99:59:59,999
The first step being ideation, or conceptualization,

74
99:59:59,999 --> 99:59:59,999
so it's having the idea or the right idea

75
99:59:59,999 --> 99:59:59,999
about the task and what needs to be done.

76
99:59:59,999 --> 99:59:59,999
And then the second step is production,

77
99:59:59,999 --> 99:59:59,999
so this is the actual execution of that task.

78
99:59:59,999 --> 99:59:59,999
And together, that results in execution of a purposeful activity.

79
99:59:59,999 --> 99:59:59,999
And when there is a breakdown

80
99:59:59,999 --> 99:59:59,999
in either one of those steps in the praxis system,

81
99:59:59,999 --> 99:59:59,999
you have apraxia,

82
99:59:59,999 --> 99:59:59,999
inability to perform these purposeful movements and tasks, okay.

83
99:59:59,999 --> 99:59:59,999
So now that you know what apraxia is,

84
99:59:59,999 --> 99:59:59,999
let's get into a little more detail

85
99:59:59,999 --> 99:59:59,999
and talk about ideational apraxia,

86
99:59:59,999 --> 99:59:59,999
which is referring to the breakdown in the ideation component.

87
99:59:59,999 --> 99:59:59,999
And so the patient with ideational apraxia

88
99:59:59,999 --> 99:59:59,999
will have no idea

89
99:59:59,999 --> 99:59:59,999
or have, don't have the right idea

90
99:59:59,999 --> 99:59:59,999
about what needs to be done with the task.

91
99:59:59,999 --> 99:59:59,999
And this includes not understanding the purpose of a tool or an object.

92
99:59:59,999 --> 99:59:59,999
So a classic example, and you may have seen this many times

93
99:59:59,999 --> 99:59:59,999
if you're in my Facebook study group

94
99:59:59,999 --> 99:59:59,999
or on my Instagram page, I also have this,

95
99:59:59,999 --> 99:59:59,999
um, is a photo of Ariel. [chuckles]

96
99:59:59,999 --> 99:59:59,999
Not a surprise, right?

97
99:59:59,999 --> 99:59:59,999
My favorite character.

98
99:59:59,999 --> 99:59:59,999
I know I talk about her all the time.

99
99:59:59,999 --> 99:59:59,999
But you have to remember that scene in <i>The Little Mermaid</i>

100
99:59:59,999 --> 99:59:59,999
where she's sitting across the dining table hall with Prince Eric

101
99:59:59,999 --> 99:59:59,999
and she sees a fork and enthusiastically

102
99:59:59,999 --> 99:59:59,999
and unabashedly, she takes it up to her hair

103
99:59:59,999 --> 99:59:59,999
and she starts brushing her hair with the fork.

104
99:59:59,999 --> 99:59:59,999
This is a really good example of ideational apraxia,

105
99:59:59,999 --> 99:59:59,999
inability to use the tool appropriately,

106
99:59:59,999 --> 99:59:59,999
because she has lost the sense,

107
99:59:59,999 --> 99:59:59,999
has no idea what the purpose of the object is,

108
99:59:59,999 --> 99:59:59,999
and so she brushes her hair with a fork.

109
99:59:59,999 --> 99:59:59,999
In the clinical setting, you might see this

110
99:59:59,999 --> 99:59:59,999
being played out with a patient trying to write with a spoon

111
99:59:59,999 --> 99:59:59,999
or trying to brush their teeth with a comb, okay.

112
99:59:59,999 --> 99:59:59,999
Another component of ideational apraxia

113
99:59:59,999 --> 99:59:59,999
can be seen when the patient tries to engage in tasks

114
99:59:59,999 --> 99:59:59,999
that require multi steps.

115
99:59:59,999 --> 99:59:59,999
So sequencing is really difficult

116
99:59:59,999 --> 99:59:59,999
because patients don't have an idea

117
99:59:59,999 --> 99:59:59,999
of the demands of the task, okay.

118
99:59:59,999 --> 99:59:59,999
So again, idea comes into play here.

119
99:59:59,999 --> 99:59:59,999
And so um, think about a patient

120
99:59:59,999 --> 99:59:59,999
trying to uh, put on a shirt,

121
99:59:59,999 --> 99:59:59,999
but instead of putting their arms through the sleeve,

122
99:59:59,999 --> 99:59:59,999
they'll try to put their legs in instead, okay.

123
99:59:59,999 --> 99:59:59,999
Or um, they might try to wear socks over their shoes,

124
99:59:59,999 --> 99:59:59,999
so they've forgotten the steps and the sequence

125
99:59:59,999 --> 99:59:59,999
in which these activities occur.

126
99:59:59,999 --> 99:59:59,999
So uh, ideational apraxia is pretty straightforward.

127
99:59:59,999 --> 99:59:59,999
You just have to remember the word "idea" in ideational

128
99:59:59,999 --> 99:59:59,999
and understand that the patient with ideational apraxia

129
99:59:59,999 --> 99:59:59,999
has no idea

130
99:59:59,999 --> 99:59:59,999
what the task uh, requires,

131
99:59:59,999 --> 99:59:59,999
so they don't know how to use the object,

132
99:59:59,999 --> 99:59:59,999
they don't know how to,

133
99:59:59,999 --> 99:59:59,999
how the objects work in relation to each other,

134
99:59:59,999 --> 99:59:59,999
and they don't understand, they don't have an idea

135
99:59:59,999 --> 99:59:59,999
of the demands of the task, okay.

136
99:59:59,999 --> 99:59:59,999
Now contrast that with um,

137
99:59:59,999 --> 99:59:59,999
ideomotor apraxia.

138
99:59:59,999 --> 99:59:59,999
This is also known as, and used synonymously,

139
99:59:59,999 --> 99:59:59,999
with motor apraxia.

140
99:59:59,999 --> 99:59:59,999
And unlike ideational apraxia

141
99:59:59,999 --> 99:59:59,999
where patients have no idea what the demand of the task is

142
99:59:59,999 --> 99:59:59,999
and how to use an object,

143
99:59:59,999 --> 99:59:59,999
in ideomotor apraxia,

144
99:59:59,999 --> 99:59:59,999
patients actually do have an idea.

145
99:59:59,999 --> 99:59:59,999
They have an understanding of what the task requires.

146
99:59:59,999 --> 99:59:59,999
Um, and given, and if their language is intact,

147
99:59:59,999 --> 99:59:59,999
they might even be able to verbalize to you

148
99:59:59,999 --> 99:59:59,999
what the task is that they have to perform.

149
99:59:59,999 --> 99:59:59,999
But in ideomotor apraxia,

150
99:59:59,999 --> 99:59:59,999
they have lost access

151
99:59:59,999 --> 99:59:59,999
to kinesthetic or kinetic memory

152
99:59:59,999 --> 99:59:59,999
related to that task,

153
99:59:59,999 --> 99:59:59,999
so they're no longer able to perform that task, okay.

154
99:59:59,999 --> 99:59:59,999
And so uh, this is really fascinating.

155
99:59:59,999 --> 99:59:59,999
Let me give you an example of a scenario.

156
99:59:59,999 --> 99:59:59,999
Uh, you see a patient,

157
99:59:59,999 --> 99:59:59,999
when you pass by a patient's hall,

158
99:59:59,999 --> 99:59:59,999
and you notice that he is brushing his hair with a comb, okay.

159
99:59:59,999 --> 99:59:59,999
20 minutes later, into the session,

160
99:59:59,999 --> 99:59:59,999
you ask him to brush his hair.

161
99:59:59,999 --> 99:59:59,999
You give him the verbal command and you say,

162
99:59:59,999 --> 99:59:59,999
"Can you show me how you brush your hair in the morning?"

163
99:59:59,999 --> 99:59:59,999
And although he was able to do it earlier in the morning,

164
99:59:59,999 --> 99:59:59,999
automatically, in context,

165
99:59:59,999 --> 99:59:59,999
he will no longer be able to do that upon verbal command,

166
99:59:59,999 --> 99:59:59,999
where if you try to ask him

167
99:59:59,999 --> 99:59:59,999
or have him mimic or imitate your movement

168
99:59:59,999 --> 99:59:59,999
and say, "Can you try to do this, brush your hair?",

169
99:59:59,999 --> 99:59:59,999
he won't, the patient won't be able to copy it.

170
99:59:59,999 --> 99:59:59,999
So, inability to perform a movement upon verbal command

171
99:59:59,999 --> 99:59:59,999
or mimic or imitate gestures.

172
99:59:59,999 --> 99:59:59,999
This is a classic indeomotor apraxia.

173
99:59:59,999 --> 99:59:59,999
Isn't the brain really fascinating? [laughs]

174
99:59:59,999 --> 99:59:59,999
Um, so uh, that's how it's differentiated

175
99:59:59,999 --> 99:59:59,999
from ideational apraxia,

176
99:59:59,999 --> 99:59:59,999
and in ideomotor, they have an understanding

177
99:59:59,999 --> 99:59:59,999
of what the task is and what needs to be done,

178
99:59:59,999 --> 99:59:59,999
but because they have lost access to that kinetic memory,

179
99:59:59,999 --> 99:59:59,999
they're no longer able to do that

180
99:59:59,999 --> 99:59:59,999
um, or execute those movements.

181
99:59:59,999 --> 99:59:59,999
Now clinically and in daily life,

182
99:59:59,999 --> 99:59:59,999
ideomotor apraxia will present as uh,

183
99:59:59,999 --> 99:59:59,999
just general uh, motor planning difficulty or in movement,

184
99:59:59,999 --> 99:59:59,999
and so what you might observe

185
99:59:59,999 --> 99:59:59,999
is movements that are um,

186
99:59:59,999 --> 99:59:59,999
awkward or imprecise or um,

187
99:59:59,999 --> 99:59:59,999
is not coordinated

188
99:59:59,999 --> 99:59:59,999
or the timing of the movement may not be right,

189
99:59:59,999 --> 99:59:59,999
so it might be too fast or too slow.

190
99:59:59,999 --> 99:59:59,999
Or you might see uh,

191
99:59:59,999 --> 99:59:59,999
a patient that has difficulty with the manipulation of objects.

192
99:59:59,999 --> 99:59:59,999
A lot of tasks that require fine motor movements,

193
99:59:59,999 --> 99:59:59,999
so think about what you might need to do

194
99:59:59,999 --> 99:59:59,999
when you want to get food out of the vending machine.

195
99:59:59,999 --> 99:59:59,999
You have to be able to manipulate coins out of your hand,

196
99:59:59,999 --> 99:59:59,999
into your palm, like those translation.

197
99:59:59,999 --> 99:59:59,999
Um, you won't be able to do that very well.

198
99:59:59,999 --> 99:59:59,999
Opening the jar, or adjusting the grip on your hand,

199
99:59:59,999 --> 99:59:59,999
fingers to use the key to open the door.

200
99:59:59,999 --> 99:59:59,999
All of these things that require precise movements

201
99:59:59,999 --> 99:59:59,999
will be challenging for patients with ideomotor apraxia.

202
99:59:59,999 --> 99:59:59,999
Am I talking really fast? [Laughs]

203
99:59:59,999 --> 99:59:59,999
My god, I'm like sweating right now. [Laughs]

204
99:59:59,999 --> 99:59:59,999
It's because I'm trying to finish this video

205
99:59:59,999 --> 99:59:59,999
before my baby wakes up

206
99:59:59,999 --> 99:59:59,999
and still have a little bit of free time to myself.

207
99:59:59,999 --> 99:59:59,999
So that's it for today.

208
99:59:59,999 --> 99:59:59,999
Congratulations again to everyone who found out

209
99:59:59,999 --> 99:59:59,999
that they passed.

210
99:59:59,999 --> 99:59:59,999
And if you are still um, preparing for your exam

211
99:59:59,999 --> 99:59:59,999
and you're still striving,

212
99:59:59,999 --> 99:59:59,999
I just want to leave you with a quote

213
99:59:59,999 --> 99:59:59,999
that was always a comfort to me,

214
99:59:59,999 --> 99:59:59,999
um, by Winston Churchill,

215
99:59:59,999 --> 99:59:59,999
which, and he once said,

216
99:59:59,999 --> 99:59:59,999
"Success is not final and failure is not fatal."

217
99:59:59,999 --> 99:59:59,999
And so to those of you who passed, um,

218
99:59:59,999 --> 99:59:59,999
know that this is just the beginning.

219
99:59:59,999 --> 99:59:59,999
This is not your final destination.

220
99:59:59,999 --> 99:59:59,999
You're going to go on to achieve so much more

221
99:59:59,999 --> 99:59:59,999
than just merely passing this exam.

222
99:59:59,999 --> 99:59:59,999
And to those of you who did not pass today, uh,

223
99:59:59,999 --> 99:59:59,999
be slow to be discouraged

224
99:59:59,999 --> 99:59:59,999
but quick to be encouraged

225
99:59:59,999 --> 99:59:59,999
knowing that this is not a fatal moment,

226
99:59:59,999 --> 99:59:59,999
no matter how much you might think it is.

227
99:59:59,999 --> 99:59:59,999
Your efforts and everything that you're learning

228
99:59:59,999 --> 99:59:59,999
and all the uh, ways that you're disciplining yourself to keep going,

229
99:59:59,999 --> 99:59:59,999
this, this is not going to be in vane.

230
99:59:59,999 --> 99:59:59,999
It will all come back to serve you well

231
99:59:59,999 --> 99:59:59,999
and serve your patients in the future.

232
99:59:59,999 --> 99:59:59,999
So, keep your spirit up and um,

233
99:59:59,999 --> 99:59:59,999
keep going. Alright?

234
99:59:59,999 --> 99:59:59,999
Okay, guys. Until next time.

235
99:59:59,999 --> 99:59:59,999
Take good care. 
I love you guys so much.

236
99:59:59,999 --> 99:59:59,999
[Blows kiss] 
Bye.
