Monocular electronystagmographic analysis of caloric nystagmus.
We compared the horizontal component of nystagmus of the right and left eyes using monocular recording of electronystagmography. We examined the eye movements of 135 patients during bithermal caloric testing and those of 50 patients during the rotation test. We measured the number of nystagmic beats, the slow-phase velocities, and the amplitudes during 10 seconds of the culmination phase of cal...
متن کاملCaloric stimulation with near infrared radiation does not induce paradoxical nystagmus
Near infrared radiation can be used for warm stimulation in caloric irrigation of the equilibrium organ. Aim of this study was to determine whether near infrared radiation offers effective stimulation of the vestibular organ, whether it is well tolerated by the patients and especially whether it is a viable alternative to warm air stimulation in patients with defects of the tympanic membrane an...
متن کاملFrom nystagmus to the air and water caloric tests.
UNLABELLED The caloric test is an important tool for the assessment of labyrinthine function. OBJECTIVE To compare the nystagmus response in the caloric tests with air at 50ºC and 24ºC and with water at 44ºC and 30ºC. STUDY DESIGN Randomized crossover clinical trial. MATERIALS AND METHODS 40 healthy individuals were submitted to a neurotological evaluation, including caloric tests with ai...
متن کاملTHE EFFECT OF ELECTROSTIMULATION ON CALORIC-INDUCED NYSTAGMUS: A PRELIMINARY STUDY
The objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. In a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. This time indicates the basal response of vestibular end-organ. After caloric irrigation, pulsed signal was applied for each...
متن کاملCerebral representations for egocentric space: Functional-anatomical evidence from caloric vestibular stimulation and neck vibration.
The internal representation of space involves the integration of different sensory inputs-visual, somatosensory/proprioceptive, vestibular-yielding reference frames which are not based on individual peripheral sensory codes, being organized instead in ego-centred (e.g. head, trunk, arm) and object- or environment-centred coordinates. Lateralized or direction-specific stimulation of peripheral s...
