15 Questions
During the PAST-POINTING AND FALLING PROCEDURE, if a patient cannot elicit the procedure with eyes closed, it indicates a lesion in which part of the vestibular system?
Utricle and saccule
If a patient with uncompensated lesion of the peripheral vestibular system deviates to the affected side during the PAST-POINTING AND FALLING PROCEDURE, what other phenomenon is typically observed?
Central vestibular nystagmus in the same direction
Which type of nystagmus is typically observed when performing the PAST-POINTING AND FALLING PROCEDURE with eyes closed?
Peripheral vestibular nystagmus
In patients with an uncompensated lesion of the peripheral vestibular system, what direction does the slow component of nystagmus usually occur during the PAST-POINTING AND FALLING PROCEDURE?
Same as past-pointing
During the Spontaneous Nystagmus Test, if nystagmus is observed in the absence of any provocative maneuvers, what type of nystagmus is typically suspected?
Central vestibular nystagmus
When performing the Positional Test, if nystagmus is elicited by changing head positions, what type of nystagmus is typically considered?
Peripheral vestibular nystagmus
If a patient's past-pointing and falling are towards the right side during the procedure, which side is most likely affected by the lesion in their peripheral vestibular system?
Left side
In patients with a lesion in the central vestibular system, what difference in nystagmus pattern might be expected compared to those with a peripheral vestibular lesion?
Nystagmus is unidirectional and more intense
During the Spontaneous Nystagmus Test, if nystagmus is observed in the absence of any provocative maneuvers, what type of nystagmus is typically suspected?
Pendular nystagmus
In patients with a lesion in the central vestibular system, what difference in nystagmus pattern might be expected compared to those with a peripheral vestibular lesion?
Nystagmus unaffected by head position changes
If a patient with an uncompensated lesion of the peripheral vestibular system deviates to the affected side during the PAST-POINTING AND FALLING PROCEDURE, what other phenomenon is typically observed?
Pendular nystagmus
Which type of nystagmus is typically associated with the Slow component of nystagmus in the PAST-POINTING AND FALLING PROCEDURE?
Peripheral vestibular nystagmus
When performing the Positional Test, if nystagmus is elicited by changing head positions, what type of nystagmus is typically considered?
Central vestibular nystagmus
During the PAST-POINTING AND FALLING PROCEDURE, if a patient cannot elicit the procedure with eyes closed, it indicates a lesion in which part of the vestibular system?
Central vestibular system
If a patient's past-pointing and falling are towards the left side during the PAST-POINTING AND FALLING PROCEDURE, which side is most likely affected by the lesion in their peripheral vestibular system?
The right side
