Motor Speech Quiz: Trivia Questions!

1.

What type of dysarthria is characterized by mono loudness, imprecise consonants, regulatory articulatory breakdowns, prolonged intervals, excess, and equal stress?

A.

It could be any of the dysarthrias, these are all going to sound alike
B.

Ataxic
C.

Hyperkinetic

Correct Answer
B. Ataxic

Explanation
Ataxic dysarthria is characterized by irregular and uncoordinated movements of the speech muscles, resulting in imprecise consonants and irregular speech rhythm. The symptoms mentioned in the question, such as mono loudness, imprecise consonants, regulatory articulatory breakdowns, prolonged intervals, excess, and equal stress, align with the characteristics of ataxic dysarthria.

2.

Which of the following is associated with ataxic dysarthria?

A.

Nystagmus
B.

Dystonia
C.

Hypotonia
D.

Tremor
E.

All the above

Correct Answer
E. All the above

Explanation
Ataxic dysarthria is a speech disorder caused by damage to the cerebellum or its connections. It is characterized by slurred speech, irregular articulation, and difficulty controlling the pitch and loudness of speech. Nystagmus, dystonia, hypotonia, and tremor are all associated with ataxic dysarthria. Nystagmus refers to involuntary eye movements, dystonia is a movement disorder causing muscle contractions, hypotonia is low muscle tone, and tremor is an involuntary rhythmic movement. Therefore, all of the above options are associated with ataxic dysarthria.

3.

Hyperkinetic dysarthrias result from lesions in what?

A.

Cerebellar circuitry
B.

Basal ganglia circuitry

Correct Answer
B. Basal ganglia circuitry

Explanation
Hyperkinetic dysarthrias result from lesions in the basal ganglia circuitry. The basal ganglia are involved in the control and coordination of movement, and when they are damaged, it can lead to involuntary, excessive, and abnormal movements, including those affecting speech and articulation. Lesions in the basal ganglia circuitry can disrupt the normal motor control processes, resulting in the characteristic symptoms of hyperkinetic dysarthrias, such as dystonia, chorea, or athetosis. The cerebellar circuitry, on the other hand, is more commonly associated with ataxic dysarthria, which involves coordination and balance impairments rather than excessive movements.

Monopitch, reduced stress, mono loudness, imprecise consonants, inappropriate silence, short rushes of speech, harsh voice, and continuous breathy voice is associated with

A.

Ataxic dysarthria
B.

Hypokinetic dysarthria
C.

Hyperkinetic dysarthria
D.

Mixed dysarthria

Correct Answer
B. Hypokinetic dysarthria

Explanation
The given symptoms such as monopitch, reduced stress, mono loudness, imprecise consonants, inappropriate silence, short rushes of speech, harsh voice, and continuous breathy voice are associated with hypokinetic dysarthria. This type of dysarthria is commonly seen in individuals with Parkinson's disease. It is characterized by reduced movement and muscle control, leading to difficulties in speech production. The symptoms mentioned in the question align with the characteristics of hypokinetic dysarthria, making it the correct answer.

5.

The clinical characteristics of tremor at rest, bradykinesia, and loss of posture are characteristics often associated with

A.

Ataxic dysarthria
B.

Hypokinetic dysarthria
C.

Hyperkinetic dysarthria

Correct Answer
B. Hypokinetic dysarthria

Explanation
The clinical characteristics mentioned, including tremor at rest, bradykinesia, and loss of posture, are commonly associated with hypokinetic dysarthria. Hypokinetic dysarthria is a type of dysarthria that occurs due to damage or dysfunction in the basal ganglia, which affects motor control. It is often seen in conditions such as Parkinson's disease, where the characteristic symptoms include resting tremors, slowness of movement (bradykinesia), and difficulty with maintaining posture. Therefore, hypokinetic dysarthria is the most appropriate choice based on the given clinical characteristics.

Dyskinesias, myoclonus, tics, chorea, ballismus, athetosis, dystonia, spasm and tremor are associated

A.

Hyperkinetic dysarthria
B.

Hypokinetic dysarthria
C.

Spastic dysarthria
D.

Ataxic dysarthria

Correct Answer
A. Hyperkinetic dysarthria

Explanation
The given symptoms such as dyskinesias, myoclonus, tics, chorea, ballismus, athetosis, dystonia, spasm, and tremor are all associated with hyperkinetic movement disorders. Dysarthria refers to difficulty in controlling the muscles used for speech. Therefore, hyperkinetic dysarthria is the most appropriate answer as it describes a speech disorder characterized by excessive, involuntary movements affecting speech muscles.

7.

Sudden muscle jerks are known as

A.

Myoclonus
B.

Dystonia
C.

Tremors

Correct Answer
A. Myoclonus

Explanation
Sudden muscle jerks are known as myoclonus. Myoclonus is a neurological condition characterized by brief, involuntary muscle contractions or jerks. These jerks can occur spontaneously or in response to external stimuli. They can affect any muscle group in the body and may be localized or generalized. Myoclonus can be caused by various factors, including neurological disorders, medication side effects, or metabolic abnormalities. Treatment options for myoclonus depend on the underlying cause and may include medications, physical therapy, or lifestyle modifications.

Volent swinging of an arm or a limb

A.

Ballismus
B.

Dystonia
C.

Myoclonus

Correct Answer
A. Ballismus

Explanation
Ballismus is a movement disorder characterized by involuntary, violent swinging of an arm or limb. It is typically caused by damage to the subthalamic nucleus in the brain, which disrupts the normal balance of signals that control movement. This results in uncontrolled and exaggerated movements, often affecting one side of the body. Dystonia and myoclonus are also movement disorders, but they present with different symptoms and mechanisms.

9.

Involuntary movements

A.

Myoclonus
B.

Dystonia
C.

Ballismus

Correct Answer
B. Dystonia

Explanation
Dystonia is a neurological disorder characterized by involuntary muscle contractions that cause repetitive or twisting movements. It can affect various parts of the body, causing abnormal postures or movements. Unlike myoclonus and ballismus, which involve sudden and jerky movements, dystonia typically leads to sustained muscle contractions. Therefore, dystonia is the most appropriate answer among the given options to describe involuntary movements associated with abnormal muscle contractions.

Lack of coordination defined by undershooting or overshoot of a movement.

A.

Myoclonus
B.

Ballismus
C.

Dysmetria

Correct Answer
C. Dysmetria

Explanation
Dysmetria refers to a lack of coordination in movement, characterized by either undershooting or overshooting the intended target. This can occur in various parts of the body, such as the limbs or eyes. Myoclonus, on the other hand, is a rapid, involuntary muscle jerk, while ballismus is a type of abnormal, flinging movement. Therefore, dysmetria is the most appropriate term to describe the lack of coordination mentioned in the question.

Involuntary eye movements.

A.

Eye occular rotatis
B.

Nystagmus
C.

Dysmetria

Correct Answer
B. Nystagmus

Explanation
Nystagmus is a condition characterized by involuntary eye movements. These movements can be rapid, jerky, or oscillatory, and can occur in both horizontal and vertical directions. Nystagmus can be congenital or acquired, and it may be caused by various factors such as neurological disorders, medication side effects, or inner ear problems. The presence of nystagmus can affect vision and balance, and it may be associated with symptoms like dizziness or difficulty focusing. Therefore, considering the given options, nystagmus is the correct answer as it best describes the involuntary eye movements mentioned in the question.

Unsteady gait

A.

Nystagmus
B.

Dysmetria
C.

Hypotonia
D.

Titubation

Correct Answer
D. Titubation

Explanation
Titubation refers to a rhythmic, involuntary movement of the head and trunk that is often seen in patients with cerebellar dysfunction. It is characterized by a back-and-forth or side-to-side movement, resembling a tremor. This movement can result in an unsteady gait, as well as other symptoms such as nystagmus (involuntary eye movements), dysmetria (inaccurate movements), and hypotonia (decreased muscle tone). Therefore, the presence of titubation supports the diagnosis of cerebellar dysfunction.
