In terms of apraxia, inability to roll over on command but doing so spontaneously is indicative of which type?

1. Ideomotor apraxia

2. Ideational apraxia

3. Oral apraxia

4. Constructional apraxia

The correct answer is: Ideomotor apraxia

The inability to roll over on command while being able to do so spontaneously is indicative of ideomotor apraxia. This condition specifically involves difficulties in performing actions on command despite the individual having the physical ability and the understanding of the task. In everyday terms, a person with ideomotor apraxia may understand what is being asked of them and can spontaneously execute the action when not under pressure to do so. In contrast, ideational apraxia involves a more profound impairment where an individual struggles to sequence actions or accomplish purposeful tasks, indicating a disruption in the understanding of the concept of the action. Oral apraxia relates specifically to the inability to perform movements with the mouth on command, affecting speech and eating. Lastly, constructional apraxia is characterized by difficulties in assembling or constructing objects, usually due to a deficit in spatial and perceptual skills rather than a lack of ability to perform an action. Therefore, the spontaneous ability in this context aligns best with ideomotor apraxia, as it illustrates the disconnect between command and action initiation.
