Question 1

Pain sensibility testing involves&#8230;&#10;A)Saying to the patient &#34;Tell me when you feel it.&#34;&#10;B)Apply the pinpoint with more pressure on the affected side.&#10;C)Asking the patient each time &#34;Does it feel sharp or dull?&#34;&#10;D)Testing integrity of the lateral corticospinal tract

Accepted Answer

Pain sensibility testing often involves asking the patient to differentiate between sharp and dull sensations to assess their ability to perceive pain accurately. This helps in evaluating the sensory function of the nervous system.

Question 2

Which of the following correctly matches the dermatomal level to the optimal sensory testing site?&#10;A)T3: Nipple level&#10;B)L4: Medial malleolus&#10;C)S1: Posterior knee&#10;D)C4: First digit of hand

Accepted Answer

The L4 dermatome is best tested at the medial malleolus.

Question 3

Which of the following is a part of the standard sensory testing procedure that serves to decrease the patient's ability to guess or predict the next accurate response during sensory testing?&#10;A)Demonstrate the test and the possible patient responses&#10;B)Test with vision eliminated&#10;C)Maintain the sensory stimulus only briefly&#10;D)Provide the stimulus in a random fashion

Accepted Answer

Providing the stimulus in a random fashion helps to prevent the patient from predicting the next stimulus, ensuring more accurate and reliable sensory testing results.

Question 4

Which is a method that can be used to screen proprioception bilaterally?&#10;A)The therapist positions a joint on one side and the patient verbally reports the position&#10;B)The therapist positions a joint on one side and then the patient moves the same limb to reproduce the same position&#10;C)The therapist positions a joint on one side and the patient quickly moves the joint to the opposite end of the range&#10;D)The therapist positions a joint on one side and then the patient positions the same joint on the opposite side to match

Accepted Answer

The correct method for screening proprioception bilaterally involves the therapist positioning a joint on one side and then the patient positioning the same joint on the opposite side to match. This method allows for a direct comparison of proprioceptive ability between the two sides of the body.

Question 5

Why would testing sensation be important if the therapist is trying to restore movement after a cerebral injury like a cerebrovascular accident (CVA) or brain injury?&#10;A)Conscious proprioception plays a very important role in refining movement during usual activity.&#10;B)Light touch sensation helps to prevent skin breakdown.&#10;C)Proprioceptive sense contributes to optimal movement while tactile sense (pressure) helps to prevent skin breakdown in a person with decreased mobility.&#10;D)Pressure touch helps to refine complex skilled movement.

Accepted Answer

The answer of Why would testing sensation be important if...

Question 6

What is the most important sensory receptor to help monitor joint position sense and joint movement sense and muscle length?&#10;A)Muscle spindles&#10;B)Golgi tendon organ&#10;C)Pacinian corpuscles&#10;D)Merkel's disc

Accepted Answer

Muscle spindles are specialized sensory receptors located within the muscle that provide information about muscle length and changes in muscle length, thus playing a crucial role in monitoring joint position and movement.

Question 7

In determining the quantity or extent of a sensory deficit you detect,which of the following best describes a distribution of peripheral sensory loss?&#10;A)A &#34;stocking/glove&#34; distribution of sensory loss&#10;B)Sensory loss in a particular peripheral cutaneous nerve distribution&#10;C)Dermatomal sensory loss&#10;D)Paraplegic sensory loss

Accepted Answer

A "stocking/glove" distribution of sensory loss is characteristic of peripheral neuropathy, where sensory deficits occur in the distal extremities, resembling the areas covered by stockings and gloves.

Question 8

Which best described the procedure for testing joint movement sense?&#10;A)Ask the patient to move the test limb into the same position,after the therapist has moved to other limb into a test position&#10;B)Ask the patient to describe the direction of joint movement while the therapist passively moves the joint&#10;C)Ask the patient to describe the direction of joint movement after the therapist has completed a movement of the test limb&#10;D)Ask the patient to mirror the position of the opposite limb

Accepted Answer

The correct procedure for testing joint movement sense involves passively moving the patient's joint and asking them to describe the direction of the movement. This assesses their ability to perceive joint movement without visual input.

Question 9

Which is the most objective way to test the threshold of sensitivity for pressure touch?&#10;A)Use of Semmes-Weinstein monofilaments&#10;B)Randomly applying sensation with deep pressure sometimes and light pressure other times&#10;C)A 1.65 filament may be the best indicator for protective sensation in the feet&#10;D)Testing the fingertips with a wisp of cotton

Accepted Answer

The use of Semmes-Weinstein monofilaments is a standardized and objective method to assess pressure sensitivity, providing consistent and quantifiable results.

Question 10

A patient has a lacunar infarct with resulting impairment of processing sensory/afferent information.Which of the following is the most likely anatomic area of the pathology?&#10;A)Precentral gyrus&#10;B)Ventral-posterior lateral nucleus (VPL) of thalamus&#10;C)Anterior horn of spinal cord&#10;D)Lateral corticospinal tract

Accepted Answer

The Ventral-posterior lateral nucleus (VPL) of the thalamus is responsible for processing sensory/afferent information from the body to the cerebral cortex. A lacunar infarct affecting this area would impair sensory information processing.
