“…The angular velocity values of the slow component were also analyzed. We considered values under 5 degrees/second to represent hypofunction and values above 50 degrees/second to represent hyperfunction 3 , 14 , 15 . A morphologic or qualitative analysis of the CT recording was performed.…”

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 and video head impulse test.RESULTS:Significantly more caloric test results than video head impulse test results were abnormal.CONCLUSIONS:The results of the caloric test and video head impulse test are distinct but complement each other. Within our sample, the caloric test was more sensitive for vestibular dysfunction. Therefore, the video head impulse test is not a suitable screening tool of the vestibular system in patients with chronic complaints.

“…The bithermal caloric test was performed in all subjects in Group B to verify bilateral vestibular involvement. According to a previous study ( 26 ), a MSPV of less than 11°/sec under warm water stimulation and less than 6°/sec under cool water stimulation indicates a hypoactive semicircular canal. Specifically for BVD, a MSPV of less than 20°/sec resulting from the bithermal caloric test is an indicator of decreased VOR function ( 3 ).…”

OBJECTIVE:The aim of this study was to assess the subjective visual vertical in patients with bilateral vestibular dysfunction and to propose a new method to analyze subjective visual vertical data in these patients.METHODS:Static subjective visual vertical tests were performed in 40 subjects split into two groups. Group A consisted of 20 healthy volunteers, and Group B consisted of 20 patients with bilateral vestibular dysfunction. Each patient performed six measurements of the subjective visual vertical test, and the mean values were calculated and analyzed.RESULTS:Analyses of the numerical values of subjective visual vertical deviations (the conventional method of analysis) showed that the mean deviation was 0.326±1.13° in Group A and 0.301±1.87° in Group B. However, by analyzing the absolute values of the subjective visual vertical (the new method of analysis proposed), the mean deviation became 1.35±0.48° in Group A and 2.152±0.93° in Group B. The difference in subjective visual vertical deviations between groups was statistically significant (p<0.05) only when the absolute values and the range of deviations were considered.CONCLUSION:An analysis of the absolute values of the subjective visual vertical more accurately reflected the visual vertical misperception in patients with bilateral vestibular dysfunction.

“…It was observed that the population of those who (24). However, it can be stated that the cold caloric test was efficient in the removal of the influence of NEOF since after their application has been possible to reach definitive conclusions in 79% of those who had some influence NEOF and underwent this stimulation, according to the literature that the findings prove ice provides the most reliable diagnostic (12)(13)(14)(15)(16)(17)(18).…”

SUMMARY Introduction:The spontaneous nystagmus with eyes closed (NEOF) can modify the results obtained during some evidence of vestibular, leading to erroneous conclusions. Objective:To characterize the patients and the type of influence on the evidence of NEOF vectonystagmography digital. Method:Retrospective study based on survey charts of patients with the presence of NEOF vectonystagmography digital, in the Outpatient Equilibriometria UNIFESP-EPM, in the years 2000 to 2007. Comparisons were made between genders, ages, direction, angular velocity of NEOF, completion of entrance examination and its influence on the results of caloric testing. Results:We found 73.7% of the population was female, mean age of 55.08 years; NEOF prevalence of horizontal and angular velocity smaller than 7 o /s in 86.7%. 59% had some kind of influence caused by the caloric test NEOF as inversion, hyporeflexia, hyperreflexia, nystagmus directional preponderance (NDP) and labyrinthine preponderance (LP) changed. The most prevalent findings were normal vestibular tests (EVN) and bilateral irritative peripheral vestibular syndrome (BIPVS). 38.7% caloric ice and realized these cases it was possible to reach a conclusion in 79%. Conclusion:The NEOF most common was the horizontal type, with VACL less than 7
