ABSTRACT

OBJECTIVE: To evaluate otolith function by comparing the findings of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential tests in patients in the inter-crisis period of unilateral definite Meniere's disease. METHODS: The sample consisted of an experimental group (n=22; 10 men and 12 women, mean age 47.32±12.82 years) with definite unilateral Meniere's disease and a control group (n=14; 5 men and 9 women, with a mean age of 41.64±13.45 years). They all underwent vestibular evaluation by means of Subjective Visual Vertical with the bucket method and, cervical and ocular Vestibular Evoked Myogenic Potential tests. The data were collected and subjected to statistical analysis. RESULTS: The results of the comparison of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential, the ocular Vestibular Evoked Myogenic Potential and, the association of cervical Vestibular Evoked Myogenic Potential with the ocular Vestibular Evoked Myogenic Potential showed no significant difference, indicating concordance among the tests. CONCLUSION: The identified abnormalities and the concordance between the combined proportion of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential findings indicate that the association of these three tests contributes to the identification of sustained and transient otolith dysfunction in the inter-crisis of unilateral definite Meniere's disease.

ABSTRACT

Introduction Postural instability is considered one of the most disabling symptoms of relapsing-remitting multiple sclerosis (RRMS). Objective To evaluate postural control in patients with RRMS. Method A total of 79 individuals between 18 and 65 years old, of both genders, were distributed into an experimental group composed of patients with RRMS ( n = 51) and in a control group composed by healthy individuals ( n = 28). The evaluation consisted of anamnesis, Dizziness Handicap Inventory (DHI), visual vertigo analog scale (VVAS), and static posturography (Tetrax IBS). Results Patients with RRMS presented mild degree in the DHI and in the VVAS; in Tetrax IBS, they presented higher or lower values of the indices of general stability, weight distribution, synchronization of postural oscillation, fall risk, and frequency bands of postural oscillation in two, five or all eight sensory conditions, in relation to the control group. Vestibular, visual and/or somatosensory dysfunction of peripheral type (51.0%) prevailed over the central type. The RRMS group, with an expanded scale of disability status > 3 points, presented a higher fall risk than with a score ≤ 3 points ( p = 0.003). There was a positive correlation of the Fall Risk Index with the total DHI Score (s = 0.380; p = 0.006) and with the VVAS score (s = 0.348; p = 0.012). Conclusion Patients with RRMS may present with inability to maintain postural control due to general instability, desynchronization and increased postural oscillation at frequencies that suggest deficiencies in the vestibular, visual, and somatosensory systems; as well as fall risk related to the state and intensity of functional disability and self-perception of the influence of dizziness on quality of life.

ABSTRACT

INTRODUCTION: Vestibular migraine is a condition that associates headache and vestibular symptoms. OBJECTIVE: To evaluate body-balance with virtual reality posturography in vestibular migraine. METHODS: A total of 26 patients in the intercritical period of vestibular migraine were compared by means of the Balance Rehabilitation UnitMT (Medical/Interacoustics) posturography with 30 controls, paired for age and gender. RESULTS: There was no significant statistical difference (p = 0.121) in the limit of stability area (cm2) between the experimental group and the control group values. There were significant differences (p < 0.05) in the values of sway velocity (cm/s) in nine of ten evaluated sensory conditions and in the pressure center displacement area (cm2) values in eight of those ten sensory conditions in the comparison between the control group and the experimental group. CONCLUSION: Posturography with virtual reality can identify changes in the sway velocity and the pressure center displacement area, characterizing the inability to maintain postural control with and without visual deprivation in situations of visual conflict and vestibulovisual interaction,in the intercritical period of the vestibular migraine.

ABSTRACT

INTRODUCTION: Postural instability is one the most common disabling features in vestibular disorders. OBJECTIVE: This study aimed to analyze the limit of stability and the influence of manipulation of visual, somatosensorial and visual-vestibular information on postural control in older adults with vestibular disorder, with and without a history of falls. METHODS: Cross-sectional study. Participants - 76 elderly patients with vestibular disorder (G1, without falls; G2, with falls) and 41 healthy elderly subjects (control group; CG). Using posturography, analyzed were limit of stability area, body center of pressure, and velocity of oscillation in the standing position in 10 conditions, including open/closed eyes, unstable surface with eyes closed, saccadic and optokinetic stimuli, and visual-vestibular interaction. RESULTS: Limit of stability area in CG was better compared with G1-2, and center of pressure values were worse in G1 than in CG. Center of pressure area in all conditions and velocity of oscillation in the following conditions: open/closed eyes, optokinetic stimulation, and visual-vestibular interaction showed worse values in G2 than in CG. Center of pressure area in the following conditions: open/closed eyes, saccadic and optokinetic stimuli, visual-vestibular interaction, and unstable surface with eyes closed showed worse values in G2 than in G1. CONCLUSION: Older adults with vestibular disorder presented reduced limit of stability and increased postural sway in the following conditions: conflict between visual and somatosensory information and visual-vestibular interaction. Deterioration in postural control was significantly associated with history of falls.

ABSTRACT

BACKGROUND: Chronic dizziness has a negative impact on emotional aspects, functional capacity, and quality of life of older people. OBJECTIVE: To compare the effects of the conventional Cawthorne & Cooksey and the multimodal Cawthorne & Cooksey protocols on patient-reported outcomes in older adults with vestibular disorders. METHODS: This is a single-blind, randomized controlled trial with three-months' follow-up. Older adults with chronic dizziness were randomly assigned to conventional or multimodal protocols. The protocols were performed in individual 50-minute sessions, twice weekly, for two months. The primary outcome was the Dizziness Handicap Inventory (DHI) and the secondary outcomes were the Visual Analogue Scale, the Vestibular Disorders Activities of Daily Living Scale, the Geriatric Depression Scale, and the Activities-specific Balance Confidence Scale. Outcomes were collected at baseline, post-treatment and three-month follow-up; and analyzed on an intention-to-treat approach. RESULTS: Eighty-two patients were randomized into the conventional (n = 40) or multimodal (n = 42) protocols. There was no between-group difference on DHI at post-treatment (Mean Difference (MD): -0.7; 95% CI: -9.2, 7.8) and at three-month follow-up (MD: -1.6; 95% CI: -9.5, 6.2). No between-group difference was found for the secondary outcomes. All patient-reported outcomes in the within-group analysis showed significant improvement between baseline and post-treatment, and changes were maintained between post-treatment and follow-up. Following treatment, 55% of patients in the conventional and 57% in the multimodal protocol reached DHI clinical improvement (decrease ≥18). CONCLUSIONS: The addition of multimodal exercises to the conventional Cawthorne & Cooksey protocol did not promote extra benefits on patient-reported outcomes in older adults with chronic dizziness.

ABSTRACT

PURPOSE: To evaluate the postural balance of type 2 diabetics with vertigo, dizziness, and/or unsteadiness. METHODS: limit of stability, pressure center displacement area, and sway velocity of 20 patients with type 2 diabetes were compared with 22 controls using the Balance Rehabilitation Unit (BRUTM, Medicaa) posturography. RESULTS: Compared to the control group, patients with type 2 diabetes showed a significantly lower limit of stability and a significantly higher-pressure center displacement area on a firm surface with eyes open, eyes closed, and horizontal vestibular-visual interaction; and higher sway velocity on a firm surface with eyes open and with eyes closed. CONCLUSION: type 2 diabetics with vertigo, dizziness, and/or imbalance compromised postural balance related to visual stimuli and vestibular-visual interaction and moderate impairment in the quality of life.

ABSTRACT

OBJECTIVES: We evaluated the simultaneous ipsilateral or contralateral involvement of the posterior and lateral, anterior and lateral, or posterior and anterior semicircular canals in patients with benign paroxysmal positional vertigo (BPPV). METHODS: The files of 2345 patients with BPPV were analyzed. RESULTS: Single-canal BPPV occurred in 2310 cases (98.5%)--unilaterally in 2058 (89.1%) and bilaterally in 252 (10.9%). Multiple-canal BPPV occurred in 35 cases (1.5%). Of these 35 cases, there was simultaneous involvement of the posterior and lateral canals on the same side (23) or on opposite sides (9) in 32 cases (91.4%). Simultaneous involvement of the anterior canal on one side and the posterior canal on the opposite side occurred in 2 cases (5.7%), and that of the anterior canal on one side and the lateral canal on the opposite side occurred in 1 case (2.9%). All cases represented canalithiasis. CONCLUSIONS: Multiple-canal BPPV was rare, and usually involved canals on the same side; simultaneous involvement of the posterior and lateral canals was much more common than involvement of the anterior and posterior canals or the anterior and lateral canals. Trauma increased the risk for multiple-canal BPPV, but not the risk for bilateral single-canal BPPV. Cupulolithiasis was not a factor in multiple-canal BPPV.

ABSTRACT

INTRODUCTION: Migraine is one of the most frequent and incapacitating headaches, with a high degree of impairment in quality of life. Its association with vestibular symptoms is common, including imbalance and postural instability. OBJECTIVE: To evaluate the body balance of patients with vestibular migraine through a static posturography test. METHODS: An experimental group of 31 patients with a medical diagnosis of vestibular migraine in the intercritical period of the disease, and a control group of 31 healthy individuals, matched for age and gender, were submitted to the eight sensory conditions of the Tetrax Interactive Balance System. The parameters analyzed were: stability index, which measures the amount of sway, global stability and ability to compensate postural modifications; weight distribution index, which compares deviations in weight distribution; synchronization index, which measures the symmetry in the weight distribution; postural sway frequency, which indicates the frequency range with more sway; and fall risk index, which expresses the probability of falls. RESULTS: The stability index was higher in the experimental group in all eight sensory conditions, with a significant difference between the groups in six of them. The weight distribution index was higher in the experimental group in all conditions, with a significant difference in three of them. The number of cases with preferential sway in F2-F4 was significantly higher in the experimental group in three conditions, and in F5-F6 in two, while the fall risk was significantly higher in the experimental group than in the control group. CONCLUSION: Patients with vestibular migraine showed compromised body balance at the static posturography test.

ABSTRACT

Peripheral vestibular diseases (PVDs) often produce many symptoms but few or no measurable signs. Tests that capture and measure signs permit the comparison between normal and vertiginous populations. The aim of our research was to find movement patterns that could identify PVD patients, using a motion analysis laboratory. The results from 21 asymptomatic volunteers who underwent the Unterberger-Fukuda stepping test were compared to those of 38 PVD patients. We established diagnosis after a complete otoneurological workup prior to the stepping test. The VICON 370 (Oxford Metrics Ltd, Oxford, UK) was used for digital capture and analysis of the stepping tests. Lateral sway, linear and total displacement, shoulder height oscillation, and torticollis angle were the same for individuals in both groups, but stepping time, body spin, and angular deviation were statistically greater in those in the patient group and might help in the diagnosis of PVDs.

ABSTRACT

UNLABELLED: In the elderly, the results of central auditory pathways behavioral assessments are considered to be difficult to read because of the possible interference of peripheral auditory pathway involvement. AIM: Assess the efficacy of the central auditory function in elderly patients who do not complain of hearing. MATERIALS AND METHODS: Case study involving 40 individuals within the age range of 60 to 75 years. The patients underwent auditory processing evaluation based on anamnesis, otorhinolaryngological exam, threshold tonal audiometry, speech recognition threshold, speech recognition index, immittance measures, stapes reflex study, synthetic phrases identification test with ipsilateral competitive message, frequency pattern test and alternate twin-syllable test through dichotic task; age range and hearing loss influenced results from the phrases identification with ipsilateral competitive message. Percentages of right answers below normal standards were seen in the three tests that assessed the central auditory functions. CONCLUSION: Elderly individuals who did not complain of hearing presented relevant prevalence of signs of central auditory function inefficiencies.

Methods The sample consisted of an experimental group (n = 22; 10 men and 12 women, mean age 47.32 ± 12.82 years) with definite unilateral Meniere's disease and a control group (n = 14; 5 men and 9 women, with a mean age of 41.64 ± 13.45 years). They all underwent vestibular evaluation by means of Subjective Visual Vertical with the bucket method and, cervical and ocular Vestibular Evoked Myogenic Potential tests. The data were collected and subjected to statistical analysis. Results The results of the comparison of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential, the ocular Vestibular Evoked Myogenic Potential and, the association of cervical Vestibular Evoked Myogenic Potential with the ocular Vestibular Evoked Myogenic Potential showed no significant difference, indicating concordance among the tests. Conclusion The identified abnormalities and the concordance between the combined proportion of the Subjective Visual Vertical, the cervical Vestibular Evoked Myogenic Potential and the ocular Vestibular Evoked Myogenic Potential findings indicate that the association of these three tests contributes to the identification of sustained and transient otolith dysfunction in the inter-crisis of unilateral definite Meniere's disease.

ABSTRACT

AIM: To assess whether more than one Epley's maneuver in the same session, compared to a single one, decreases the number of sessions necessary to suppress positional nystagmus. METHODS: Epleys maneuver was done in 123 patients with BPPV due to unilateral posterior semicircular canal canalolithiasis. The number of sessions for positional nystagmus suppression was compared in two groups of patients. Group I consisted of 75 patients submitted to a single Epley's maneuver on weekly sessions and group II consisted of 48 patients that were submitted to four Epley's maneuvers during the first session. RESULTS: Group II showed greater nystagmus latency and duration than group I (p<0.05). The number of sessions and standard deviation showed by group I was greater than in group II (p=0.008). We observed a significant association between number of sessions and group (p=0.039) studied. Group II had 21.4% more nystagmus-free patients following only one session (CI95% [7.7% - 35.1%]). CONCLUSION: Repeated Epley's maneuvers in less sessions rendered more positional nystagmus-free patients when compared to those submitted to more sessions of single maneuvers.

ABSTRACT

UNLABELLED: The effects of Epley's maneuver in benign paroxysmal positional vertigo (BPPV) associated with Menière's disease are controversial. AIMS: To evaluate the progression of positional vertigo and nystagmus after one or more of Epley's maneuvers in BPPV associated with Menière's disease, and the recurrence of BPPV. METHOD: a retrospective study of 62 patients with BPPV associated with Menière's disease, that underwent Epley's maneuver, and that were monitored during 12 months after elimination of positional nystagmus. RESULTS: One Epley's maneuver was required to eliminate positional nystagmus in 80.7% of the patients, two in 16.1%, and three in 3.2%; after elimination of nystagmus, positional vertigo was suppressed in 71.0% of the patients, improved in 27.4% and remained unaltered in 1.6%. Four weeks after elimination of positional nystagmus, all patients were asymptomatic. Recurrence of BPPV was seen in 19.4% of the cases, with elimination of the positional vertigo and nystagmus by means of the specific maneuver for the involved canal. CONCLUSION: In BPPV associated with Menière's disease, vertigo and positioning nystagmus were eliminated with one, two or three Epley maneuvers. BPPV recurrence was resolved by using a specific maneuver for the affected canal.

ABSTRACT

UNLABELLED: Drug treatment is an important option for the treatment of peripheral vestibular diseases. AIM: To identify the drug component associated with optimal integrated balance therapy (IBT) for Ménières disease or other peripheral vestibular disorders. MATERIALS AND METHODS: Analysis of a series of patients with Ménières disease patients or patients with other peripheral vestibular disorders that received IBT involving either no medication or betahistine, cinnarizine, clonazepam, flunarizine or Ginkgo biloba during 120 days. RESULTS: In Ménières disease, significant differences were observed for all drug therapies (60 days) versus no medication; betahistine was significantly more effective than all other drugs at 60 and 120 days. For non-Ménières disorders, significant differences were observed among betahistine, cinnarizine, clonazepam and flunarizine and no medication after 60 days; all drug therapies were significantly more effective than no medication after 120 days; betahistine, cinnarizine or clonazepam were equally effective and betahistine was more effective than flunarizine and EGb 761. All treatment options were well tolerated. CONCLUSIONS: Drug therapies were more effective than no medication in the IBT for patients with Ménières disease or other peripheral vestibular disorders. Betahistine was the most effective medication for patients with Ménières disease and was as effective as cinnarizine and clonazepam for other peripheral vestibular disorders.

ABSTRACT

INTRODUCTION: Otolith function can be studied by testing the subjective visual vertical, because the tilt of the vertical line beyond the normal range is a sign of vestibular dysfunction. Benign paroxysmal positional vertigo is a disorder of one or more labyrinthine semicircular canals caused by fractions of otoliths derived from the utricular macula. OBJECTIVE: To compare the subjective visual vertical with the bucket test before and immediately after the particle repositioning maneuver in patients with benign paroxysmal positional vertigo. METHODS: We evaluated 20 patients. The estimated position where a fluorescent line within a bucket reached the vertical position was measured before and immediately after the particle repositioning maneuver. Data were tabulated and statistically analyzed. RESULTS: Before repositioning maneuver, 9 patients (45.0%) had absolute values of the subjective visual vertical above the reference standard and 2 (10.0%) after the maneuver; the mean of the absolute values of the vertical deviation was significantly lower after the intervention (p<0.001). CONCLUSION: There is a reduction of the deviations of the subjective visual vertical, evaluated by the bucket test, immediately after the particle repositioning maneuver in patients with benign paroxysmal positional vertigo.

ABSTRACT

Abstract Introduction Postural instability is considered one of the most disabling symptoms of relapsing-remitting multiple sclerosis (RRMS). Objective To evaluate postural control in patients with RRMS. Method A total of 79 individuals between 18 and 65 years old, of both genders, were distributed into an experimental group composed of patients with RRMS (n = 51) and in a control group composed by healthy individuals (n = 28). The evaluation consisted of anamnesis, Dizziness Handicap Inventory (DHI), visual vertigo analog scale (WAS), and static posturography (Tetrax IBS). Results Patients with RRMS presented mild degree in the DHI and in the VVAS; in Tetrax IBS, they presented higher or lower values of the indices of general stability, weight distribution, synchronization of postural oscillation, fall risk, and frequency bands of postural oscillation in two, five or all eight sensory conditions, in relation to the control group. Vestibular, visual and/or somatosensory dysfunction of peripheral type (51.0%) prevailed over the central type. The RRMS group, with an expanded scale of disability status > 3 points, presented a higher fall risk than with a score ≤ 3 points (p = 0.003). There was a positive correlation of the Fall Risk Index with the total DHI Score (s = 0.380; p = 0.006) and with the VVAS score (s = 0.348; p = 0.012). Conclusion Patients with RRMS may present with inability to maintain postural control due to general instability, desynchronization and increased postural oscillation at frequencies that suggest deficiencies in the vestibular, visual, and somatosensory systems; as well as fall risk related to the state and intensity of functional disability and self-perception of the influence of dizziness on quality of life.

ABSTRACT

Our purpose was to determine the possible existence of a relationship between abnormal findings from head-only rotation and those from caloric tests applied in patients with peripheral vestibular disorders. We retrospectively studied the head-only rotation and caloric test results of 75 patients experiencing dizziness and peripheral vestibular dysfunction. We assessed the relationship between abnormal test results using the Cramér coefficient. Abnormal findings in the head-only rotation test occurred in 87.5% of patients with vestibular hypoexcitability and in 94.3% of those with hyperexcitability or directional preponderance of post-caloric nystagmus. Statistical analysis of the association between the values found for the parameters of head-only rotation and caloric test results revealed a Cramér coefficient that was less than 0.70. We found no relationship between abnormal findings from head-only rotation and caloric tests applied to individuals with peripheral vestibular disorders.

ABSTRACT

AIM: To assess whether or not the parameters of fixed and randomized saccadic movements, of pendular tracking and of optokinetic nystagmus in the digital vectonystagmography may show abnormalities in patients with possible diagnosis of peripheral vestibular dysfunction. METHOD: 60 patients with dizziness of peripheral vestibular origin, from 12 to 82 years of age, males and females, were evaluated in the Universidade Federal de São Paulo. Ocular movement parameter findings were compared to a normal pattern. RESULTS: Fixed saccadic movements were altered in 100% of the cases as to latency, and in 35.0% of the cases as to speed; the randomized saccadic movements were altered in 100% of the cases as to latency, in 78.3% as to precision, and in 1.7% as to speed; the pendular tracking showed a gain alteration in the frequencies of 0.1 Hz in 15% of the cases, 0.2 Hz in 21.7%, and 0.4 Hz in 13.3%; the optokinetic nystagmus showed an alteration of the angular speed in the slow component in 1.7% of the cases, and in gain in 5.0%. CONCLUSION: Fixed saccadic movement latency and speed, randomized saccadic movement latency, precision and speed, pendular tracking gain, slow component angular speed, and optokinetic nystagmus gain in the digital vectonystagmography may show abnormalities in patients with possible diagnosis of peripheral vestibular dysfunction.

ABSTRACT

INTRODUCTION: Visual stimuli can induce vestibular adaptation and recovery of body balance. OBJECTIVE: To verify the effect of visual stimuli by digital images on vestibular and body balance rehabilitation of peripheral vestibular disorders. METHODS: Clinical, randomized, prospective study. Forty patients aged between 23 and 63 years with chronic peripheral vestibular disorders underwent 12 sessions of rehabilitation with visual stimuli using digital video disk (DVD) (experimental group) or Cawthorne-Cooksey exercises (control group). The Dizziness Handicap Inventory (DHI), dizziness analog scale, and the sensitized Romberg static balance and one-leg stance tests were applied before and after the intervention. RESULTS: Before and after the intervention, there was no difference between the experimental and control groups (p>0.005) regarding the findings of DHI, dizziness analog scale, and static balance tests. After the intervention, the experimental and control groups showed lower values (p<0.05) in the DHI and the dizziness analog scale, and higher values (p<0.05) in the static balance tests in some of the assessed conditions. CONCLUSION: The inclusion of visual stimuli by digital images on vestibular and body balance rehabilitation is effective in reducing dizziness and improving quality of life and postural control in individuals with peripheral vestibular disorders.
