Baseline Shift and Gain Asymmetry in the Caloric Test
The caloric test is quantified using two parameters: unilateral weakness (UW) and directional preponderance (DP). The clinical usefulness of UW, also known as canal paresis, is well established but there is considerable debate about the value of DP. Some laboratories choose not to include DP in the interpretation of the caloric test. One reason for the low clinical value of abnormal DP may be t...
متن کاملThe Caloric Test and the Video Head-Impulse Test in Patients with Vertigo
MATERIALS and METHODS: This is a prospective work in 123 patients with different types of vestibular disease seen because of dizziness in which both procedures were performed the same day. First, the spontaneous nystagmus and head-shake nystagmus were measured. The video head-impulse test was carried out, and finally, the caloric test was performed with water at two different temperatures. Both...
متن کاملCaloric Test versus Rotational Chair Test in Patients with Peripheral Vestibulopathy
OBJECTIVE: 1) To correlate caloric results with sinusoidal and step-velocity rotary chair gain, phase, asymmetry and time constant values in all patients; 2) To evaluate sensitivity, specificity, positive predictive value and negative predictive value of both tests in patients with vestibular dizziness. STUDY DESIGN: Retrospective case review. SETTING: Academic tertiary care vestibular function...
متن کاملSensitivity of caloric test and video head impulse as screening test for chronic vestibular complaints
OBJECTIVE: This study compared the results of the caloric test with those of the video head impulse test obtained during the same session and evaluated whether the former can be used to screen for non-acute vestibular dysfunction. METHODS: A total of 157 participants complaining of dizziness with vestibular characteristics of varying durations and clinical courses completed the caloric test a...
متن کاملRelationship between video head impulse test (vHIT) and caloric test in patients with vestibular neuritis.
INTRODUCTION AND OBJECTIVES The caloric test is the gold standard for the loss of vestibular function diagnosis. The Video Head Impulse Test (vHIT) assesses the same reflex by using a video- assisted examination of the impulsive maneuver. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at...
