NPTE-PT Neuromuscular System Examination

Question 1

Which test assesses the integrity of the corticospinal tract by stroking the lateral plantar surface of the foot?

Accepted Answer

Babinski sign

Answer

The Babinski sign is elicited by stroking the lateral plantar surface, with an abnormal response (dorsiflexion of the great toe and fanning of the others) indicating upper motor neuron dysfunction.

Question 2

A patient presents with impaired vibration sense and proprioception but intact pain and temperature sensation. Which spinal cord pathway is most likely affected?

Accepted Answer

Dorsal columns

Answer

The dorsal columns (posterior funiculi) carry vibration and proprioception, while the lateral spinothalamic tract carries pain and temperature.

Question 3

During examination, a physical therapist notes that a patient cannot perform rapid alternating movements with the hand. This finding is called:

Accepted Answer

Dysdiadochokinesia

Answer

Dysdiadochokinesia is the inability to perform rapid alternating movements and is a classic sign of cerebellar dysfunction.

Question 4

Which cranial nerve is tested by assessing the patient's ability to shrug shoulders against resistance?

Accepted Answer

CN XI (Spinal Accessory)

Answer

Cranial nerve XI (spinal accessory) innervates the trapezius and sternocleidomastoid, both tested by shoulder shrug and head rotation against resistance.

Question 5

A patient with a C5 spinal cord injury would be expected to retain which of the following motor functions?

Accepted Answer

Shoulder abduction and elbow flexion

Answer

C5 innervates the deltoid and biceps, so shoulder abduction and elbow flexion are preserved at this level of injury.
