Q

What is the interpretation of the VOR Cancellation test?

A
  • Remember… the VOR is the ability of the eyes to move equal and opposite to head motion, to keep the image stable on the retina (aka gaze stabilization)
  • Therefore… VOR cancellation is the ability to “cancel” the VOR and move the eyes together with the head
  • Normal = head and eyes move together with minimal to no symptoms reported by the patient
  • Abnormal = inability of eyes to stay on target, dizziness or other symptoms reported by patient
  • Possible central vestibular dysfunction

Q

Why should a patient refrain from taking Meclizine 24 hours prior to a Benign Paroxysmal Positional Vertigo (BPPV) examination?

A

• MECLIZINE is a prescription drug (Antihistamine) that suppresses the vestibular ocular reflex in an attempt to reduce vertigo symptoms
*Many physicians (especially ED physicians) will prescribe Meclizine for people who have vertigo
• Correct BPPV diagnosis is dependent on visualizing the correct nystagmus

90
Q

What is the Benign Paroxysmal Positional Vertigo (BPPV) treatment Left OR Right Horizontal CUPULOLITHIASIS?

A

Gufoni (Casani)

91
Q

For the BPPV treatment for cupulolithiasis, what should be done after performing a liberatory maneuver?

A

Reassess with positional testing.
• Following the maneuver you should:
1. Continue to see a cupulolithiasis nystagmus pattern and need to perform the liberatory maneuver again
OR
2. See a conversion of the nystagmus to a canalithiasis pattern and need to perform a
repositioning maneuver

92
Q

What are the characteristics of patient tolerance and management in the treatment of BPPV?

A

• You should ALWAYS reassess immediately following a repositioning or liberatory maneuver to assess the effectiveness of your treatment
• If you did not clear a canal (or liberate the otoconia) on the first attempt, you can perform maneuvers multiple times in one treatment session
This is primarily based on patient tolerance!

93
Q

  4. 2-3 times per day

Always have the patient rate their dizziness from 0-10 prior to the exercise. Any increase in their rating after competition of the activity should reduce with in 5 minutes. IF it DOES NOT decrease DISCONTINUE exercises for that day.

136
Q

What are the characteristics of the progression of habituation?

A

• As individuals become more comfortable, you can add more challenging or complex
movements that induce symptoms
• Ex: Change base of support, movement speed, direction, frequency
• Unfortunately, there is not always a transfer of improvement from one task to another

137
Q

What is the overall goal for the habituation mechanism of treating vestibular dysfunction?

To implement strategies that can replace or compensate for
lost and/or impaired function.

Examples include: increases in strength, ROM and proprioception; assistive
devices or activity modification

139
Q

Afferent information from the cervical spine is known to influence postural stability by effecting the vestibular and ocular neural networks

141
Q

What are the ways to make vestibular exercises harder?

A
  • Modifying base of support
  • Incorporating head and oculomotor movements
  • Increasing speed of movements
  • A good rule of thumb is to:
