MSTH 308: Derms, Myos, DTRs, ULTTs

Which of the following techniques is commonly used to map dermatomes on the human body?

• Electromyography (EMG)

• Pinprick and light touch testing

• Magnetic Resonance Imaging (MRI)

• Ultrasound

What is the primary method for assessing myotomes in a clinical setting?

• Reflex hammer testing

• Muscle strength testing

• Sensory nerve conduction studies

• Blood pressure measurement

Which reflex is commonly tested to assess the integrity of the S1 nerve root?

• Biceps reflex

• Triceps reflex

• Patellar reflex

• Achilles reflex

What is the clinical significance of dermatomes in diagnosing neurological conditions?

• They help in determining muscle strength.

• They assist in localising nerve root lesions.

• They are used to measure blood pressure.

• They are essential for assessing joint mobility.

How are myotomes and reflexes correlated in a neurological examination?

• Myotomes are assessed through sensory testing, while reflexes are not related.

• Myotomes and reflexes are unrelated in clinical practice.

• Myotomes are assessed through muscle strength, and reflexes help confirm nerve root function.

• Reflexes are used to assess myotomes directly.

When performing ULTTs, which joint is generally moved into position last?

• Elbow

• Wrist

• Shoulder

• Fingers

Which nerve root is primarily assessed by the biceps reflex test?

• C5-C6

• C6-C7

• C7

• C8

What is the significance of the Babinski sign in a neurological examination?

• It indicates normal reflex activity.

• It suggests upper motor neuron lesion.

• It confirms lower motor neuron lesion.

• It is used to assess sensory nerve function.

The Achilles tendon reflex is used to assess which spinal level?

• L2

• L4

• S1

• L5

Loss of sensation over the medial aspect of the lower leg and foot is indicative of an issue with which dermatome?

• L3

• L4

• L5

• S1
