RESUMEN
There are ample of studies on use of VSS in order to find out the severity of vertigo symptoms, also studies portray the usefulness of VHQ to study the impact of vertigo on lifestyle; however, there is dearth of information on whether there is any correlation between the vertigo symptoms and affection on quality of life (QOL). Hence, the need arises to find out the correlation between VSS and VHQ for the better, documentation of symptoms and affection on QOL, as it will benefit treatment efficacy. METHODS: Sample size was 40. All the patients were given two questionnaires VSS and VHQ, which are self-administered. RESULTS: Correlation was found between total VSS and its dimensions with VHQ using Karl Pearson correlation coefficient method. Thus, we concluded that increase or decrease in the scores of VSS has an effect on the scores of VHQ.
RESUMEN
BACKGROUND AND OBJECTIVES: This study aims to evaluate the usefulness of customized vestibular exercise through literature review. MATERIALS AND METHOD: We searched several literature database such as Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library etc., with the following inclusion criteria: 1) studies of patients with dizziness and balance disorders, 2) studies in which a customized vestibular exercise was performed, and 3) studies in which one or more of the appropriate medical outcomes have been reported. At the same time, we excluded the following: 1) non-human studies and pre-clinical studies, 2) non-original articles, for example, non-systematic reviews, editorial, letter and opinion pieces, 3) research not published in Korean and English, 4) grey literature (thesis, congress or conference materials, abstract etc.), and 5) case studies. Finally, 10 studies were selected and analyzed. RESULTS: The safety of customized vestibular exercise was reported in three documents which reported no side effects related to the procedure. The effectiveness of customized vestibular exercise was proven by the assessment of symptom change, functional change, and other physiological measures based on a total of 10 randomized clinical trial studies. CONCLUSION: For patients with vestibular dysfunction, a customized vestibular exercise can be a safe and effective technique for improving dizziness and balance function.

Introduction:The Vertigo symptom scale (VSS) is a well established tool for the evaluation of vestibular disorders and the associated symptoms of autonomic arousal and somatosensation. By using a validated Malay version of vertigo symptom scale (MVVSS) questionnaire, the severity of the vertigo from patients’ perspective can be determined and rated. Before MVVSS can be applied clinically among Malaysians, it was of interest to determine its clinical value in identifying vestibular disorders. Method: Forty normal and 65 PVD subjects participated in this cross-sectional study. Normal subjects were recruited amongst Universiti Sains Malaysia (USM) staff and students who had no history of ear and vestibular disorders. Results: Mean total score of MVVSS in normal and PVD subjects were 13.9 ± 11.1 and 30.1 ± 20.9, respectively. When the total scores of normal and PVD group were compared, the Mann-Whitney U test showed that there was a significant difference between the two groups (p<0.05). This is consistent with previous studies. It was also of interest to see if subtypes of PVD [benign paroxymal positional vertigo (BPPV), Meniere’s disease, labyrinthitis and unknown] have different MVVSS results. However, analysis of variance (ANOVA) found no significant difference in term of outcomes of MVVSS among the different PVD pathologies. Using receiver operating characteristic curve (ROC) method, the sensitivity and specificity of MVVSS were 71% and 60%, respectively. Conclusion: MVVSS is able to discriminate clinically among the normal and PVD subjects. However, it is not a good indicator for differential diagnosis of PVD subtypes, at least in this study. Its sensitivity and specificity in clinical diagnosis are reasonably high. Perhaps a bigger sample size would be useful to further study the clinical usefulness of MVVSS.
RESUMEN
BACKGROUND & OBJECTIVE: Although some authors (Hamid et at.(1988) ; Moschner et at. (1994)) described that the vestibular function test (VFT) is useful in the differential diagnosis of central vestibular disorders, the reliability of VFT is not well established. The purpose of this study is to know the sensitivity and specificity of VFT for the diagnosis of central vestibular dysfunction. This study correlates VFT and MRI findings in the patients with central vestibular disorder. METHODS: Among the patients who were given VFT and brain MRI study, we selected 131 patients whose VFT results were not compatible with the peripheral vestibular dysfunction. Also we classified the MRI and VFT findings into groups of brainstem or cerebellar lesions and others. We got the sensitivity and specificity of VFT for the diagnosis of central vestibular dysfunction and the differentiation of brainstem or cerebellar lesions from others. Then we compared the results of VFT in each group. Results : 1. Among 71 patients with central vestibular disorder demonstrated by VFT, 41 patients showed lesions in MRI imaging. Among 60 patients whose VFT results were normal, 9 patients were found to have central lesions by MRI. Overall the sensitivity and specificity of VFT for diagnosing the central lesions were 82.0%, 63.0% respectively. 2. Common features in all central vestibular dysfunction patients are abnormalities in CDP and saccade reflex testing. 3. Overall the sensitivity and specificity of VFT for differentiating the brainstem or cerebellar lesions from others were 41.1%, 95.8% respectively. The percentage of patients who showed increased vestibulo-ocular reflex (VOR) gain during gaze fixation test is highly correlated with group of brainstem or cerebellar lesions detected in MRI( p < 0.001). Conclusion : VFT is a sensitive study in detecting and predicting the lesions of central vestibular system. But the ability to differentiate and localize the central lesions is remained to be improved.
