  3. Ask the pt to maintain their gaze fixed on your nose
  4. Gently move the pts head from side to side to make sure they are relaxed

26
Q

Neuroanatomy of head thrust

A

vestibular system

a positive test is indicative of peripheral vestibular dysfunction on the side rotated to during the corrective saccade

27
Q

Documentation of Head thrust test

A

document the presence of a corrective saccade with head impulse test and the direction of the head movement that produced a corrective saccade

positive = sudden corrective movement back to the examiner’s nose when the head stops moving to refix gaze on the target

  6. After 20 rotations ask the patient to open their eyes
29
Q

Neuroanatomy of head shaking test

A

vestibular system

30
Q

Documentation of head shaking test

A

document the presence or absence of nystagmus and the direction of nystagmus if present

the presence of nystagmus indicates a unilateral peripheral hypofunction, and will beat away from impaired side

31
Q

vestibular system

ability of central nervous system to override the peripheral vestibulo-ocular reflex to maintain gaze fixed on a target

33
Q

Documentation of VOR cancellation

A

document the presence of intact smooth pursuit OR the presence of saccadic intrusions/corrections as the patient tracks the target

34
Q

  2. patient should be a distance of 6m from eye chart
  3. Stand behind the patient with a firm grasps on their head and rotate the head side to side at a speed of 2Hz, then repeat in vertical direction
  4. Instruct the patient to read the chart starting from the largest type to the line with the smallest type that can be read accurately
  5. A difference of 3 lines or more between the static and dynamic DVA is an indicator of gaze instability

A

Substitution
1. Using a stationary target, have the patient focus on it
2. They have them close their eyes and move their head for 1-2 min.

40
Q

Active eye-head movements between two targets

A

Substitution
1. Place two targets on a neutral wall at nose level, and should be placed close enough that the patient is not using peripheral vision
2. Instruct the patient to move eyes towards second target without head movement, and then move head to the second target
