ABSTRACT

RESUMO Objetivo avaliar se a posturografia, exame que avalia a habilidade de manter o equilíbrio em condições sensoriais conflitantes, pode identificar risco de queda em idosos com tontura. Métodos comparar os resultados posturográficos de idosos com e sem história de quedas, pareados por gênero, idade e diagnóstico etiológico da tontura. Resultados dezoito idosos com quedas - 4 com único episódio e 14 com história de 2 ou mais quedas no último ano - foram comparados com 18 idosos sem quedas, pareados por gênero, idade e diagnóstico etiológico. Pacientes com quedas apresentaram resultados piores para as análises de dependência visual (p=0,04, p=0,01, p=0,03). Pacientes com quedas recorrentes (2 ou mais episódios) apresentaram piores resultados em diversas condições sensoriais: somatossensorial, vestibular, dependências visuais e índice de equilíbrio composto. Conclusão a posturografia mostrou-se útil na identificação de idosos com quedas, principalmente em indivíduos com quadros recorrentes.


ABSTRACT Purpose the aim of this study is to determine whether posturography, an exam used to investigate the ability to maintain balance under conflicting sensory conditions, can identify the risk of falls in eldery patients with dizziness. Methods to compare the posturographic results of elderly people with falls vs elderly people with no falls, paired by sex, age and dizziness etiology. Results 18 fallers, and, of these, 14 with two or more falls in the last year were compared with 18 elderly people without falls. Comparing subjects without falls vs subjects with at least one fall in the last year, fallers obtain worse scores in conditions of visual dependence. Comparing non fallers with subjects with two or more falls, people with recurrent falls obtain worse score in several conditions: somatosensorial, vestibular, visual conflict, and in the main measure, the composite score. Conclusion posturography appears to be a useful tool to identify those at high risk of recurrent falls.

ABSTRACT

El vértigo posicional paroxístico benigno (VPPB) es reconocido como la principal causa de vértigo de origen periférico en adultos, ya que, si bien la etiología del VPPB aún no se ha demostrado plenamente y se clasifica como la mayoría de los casos, se puede identificar el desprendimiento de otolitos y su desplazamiento en uno de los tres canales semicirculares. Una anamnesis cuidadosa puede abordar el diagnóstico clínico del VPPB, pero la confirmación se obtendrá por medio de maniobras de diagnóstico especificas de acuerdo a cuál de los canales está involucrado. Este trastorno altera la capacidad de llevar a cabo actividades de la vida cotidiana que determinan un aumento significativo en el riesgo de caídas y las consiguientes lesiones. La mayoría de los pacientes se recuperan después del tratamiento, sin embargo, hasta dos tercios de éstos pueden percibir inestabilidad prolongada, aturdimiento y malestar definidos como mareo residual. Esta sintomatología residual después de la resolución del VPPB es variable entre los pacientes, siendo el tiempo de duración de los síntomas residuales de aproximadamente de 1 a 3 semanas, existiendo algunos pacientes que pueden recuperarse más tardíamente. En esta revisión analizaremos el mareo residual, describiendo su expresión clínica, diagnóstica, fisiopatológica y tratamientos actuales de esta entidad clínica.


Benign paroxysmal positional vertigo (BPPV) is recognized as the main cause of peripheral vertigo in adults, although the etiology of BPPV has not yet been fully demonstrated and is classified as idiopathicin most cases, detachment of otoliths and their displacement in one of the three semicircular canals can be identifie. A careful history can address the clinical diagnosis of BPPV, but confirmation will be obtained through specific diagnostic maneuvers according to which canal is involved. This disorder alters the ability to carry out activities of daily living that determine a significant increase in the risk of falls and consequent injuries. Most patients recover after treatment, however, up to two thirds of these patients may perceive prolonged instability, dizziness and discomfort defined as residual dizziness. This residual symptomatology following BPPV resolution is variable among patients, the duration of residual symptoms can last 1 to 3 weeks, with some patients may recover later on. In this review, we will analyze residual dizziness, describing its clinical presentation, diagnosis, pathophysiology and current treatments of this clinical entity.

ABSTRACT

Abstract Introduction Peripheral vestibular disorders can lead to cognitive deficits and are more common in elderly patients. Objective To evaluate and correlate cognitive, balance and gait aspects in elderly women with chronic peripheral vestibular dizziness, and to compare them with elderly women without vestibular disorders. Methods Twenty-two women presenting peripheral vestibular dizziness episodes for at least six months participated in the study. The individuals were categorized by dizziness severity level: moderate (n = 11) or severe (n = 11). The control group (n = 11) included women showing no vestibulopathy, light-headedness or dizziness. Cognitive assessments and semi-static and dynamic balance assessments were performed with the Balance Master (Neurocom International, Inc., Clackamas, OR), while the Dizziness Handicap Inventory provided a score for the severity of the symptoms. The groups were submitted to statistics of inference and correlation between cognitive, balance and stability variables. Results The group with severe dizziness showed higher sway speed of the center of pressure in the anteroposterior direction, smaller step length, and slower gait than the control group. Regarding the cognitive variables, the group with severe dizziness symptoms presented significant correlations with stability and gait variables. Conclusion The relationship between cognitive aspects, balance and gait was stronger in women with severe dizziness than in those with no vestibulopathy.

ABSTRACT

RESUMEN Los trastornos vestibulares funcionales se constituyen como una de las causas más frecuentes de consulta por vértigo y trastornos del equilibrio. El mareo postural perceptual persistente (MPPP) es un síndrome recientemente definido, enmarcado en la categoría de síndromes vestibulares crónicos, que agrupa trastornos vestibulares funcionales crónicos como el vértigo postural fóbico, el malestar con el movimiento espacial, el vértigo visual y el mareo subjetivo crónico. El MPPP se manifiesta por síntomas de mareo, inestabilidad y/o vértigo no rotatorio, persistentes, exacerbados por cambios posturales, movimientos y exposición a distintos estímulos visuales. El tratamiento de este cuadro es más sencillo de lo que parece, basado en psicoeducación efectiva respecto a la patología como primer abordaje, adicionando o no rehabilitación vestibular, uso de inhibidores selectivos de la recaptación de serotonina y/o terapia cognitivo conductual. Se presentan dos casos clínicos de pacientes diagnosticados con MPPP y su respuesta a tratamiento.


ABSTRACT Functional vestibular disorders are one of the most frequent causes of consultation due to vertigo and balance disorders. Persistent postural-perceptual dizziness (PPPD) is a recently defined syndrome, categorized as a chronic vestibular syndrome, that includes functional vestibular disorders such as phobic postural vertigo, space-motion discomfort, visual vertigo and chronic subjective dizziness. PPPD manifests with dizziness, unsteadiness and/or non-spinning vertigo, which are persistent, exacerbated by postural changes, movements and exposure to various visual stimuli. PPPD treatment is simpler than it may seem initially. It is based on effective psychoeducation related to the pathology in the first place, followed, or not, by vestibular rehabilitation, use of selective serotonin reuptake inhibitors and/or cognitive behavioral therapy. We present two clinical cases of patients diagnosed with PPPD and their response to treatment.

ABSTRACT

ABSTRACT Changes in postural balance and visual complaints are frequent consequences of stroke. We aimed to investigate the symptoms and the vestibular and oculomotor functions of patients with dizziness post ischemic and hemorrhagic stroke and compare the results among them. Methods: Fifty patients with dizziness after stroke were evaluated through a clinical anamnesis and computerized vector electronystagmography: calibration of ocular movements, spontaneous nystagmus, semi-spontaneous nystagmus, pendular tracking, optokinetic nystagmus, rotary chair testing, and the caloric test. Results: All patients complained of dizziness, especially imbalance. Ischemic stroke in the carotid territory was the prevalent type. Visual complaints were reported by 56% of the sample and were related to abnormalities in oculomotor and caloric tests. Conclusion: The occurrence of visual symptoms was related to some abnormalities in the vector electronystagmography tests, being more frequent in cases of stroke in the vertebrobasilar system, and with oscillopsia and reduced visual acuity as symptoms.


RESUMO Alterações no equilíbrio postural são consequências frequentes no acidente vascular cerebral (AVC). O objetivo deste estudo foi investigar os sintomas e as funções vestibular e oculomotora de sujeitos com tontura após AVC isquêmico e hemorrágico, comparando seus resultados. Métodos: Foram avaliados 50 sujeitos com tontura após AVC, por meio de anamnese clínica e vectoeletronistagmografia computadorizada (VENG): calibração dos movimentos oculares; nistagmo espontâneo e semi-espontâneo; rastreio pendular; nistagmo optocinético; prova rotatória pendular decrescente e prova calórica com estímulo a ar. Resultados: Todos relataram tontura, principalmente do tipo desequilíbrio. O AVC isquêmico e no sistema carotídeo foi o mais frequente. Sintomas visuais pós-AVC foram referidos por 56% da amostra, os quais tiveram relação com alterações nas provas oculomotoras e calórica da VENG. Conclusão: A ocorrência de sintomas visuais relacionou-se a alterações em alguns testes. Essas alterações foram mais frequentes nos casos de AVC da circulação posterior, naqueles com oscilopsia e diminuição da acuidade visual.

ABSTRACT

ABSTRACT OBJECTIVE To assess the effects of the lian gong practice as a rehabilitation strategy in primary health care on the quality of life and functional capacity of people with dizziness. METHODS Randomized controlled clinical trial. Thirty-six people, who were complaining of dizziness or vertigo without the presence of central signs and were referred by the physician of primary health care participated in the study. The individuals were randomly allocated to the three experimental conditions: lian gong group (n = 11), vestibular rehabilitation group (n = 11) and control group (n = 14). The interventions were weekly, in group, with duration of 12 sessions. The participants were evaluated before and after the intervention regarding quality of life by the 36-Item Short Form Health Survey and the functional capacity by the Short Physical Performance Battery. RESULTS The scores of all domains of the Short Form Health Survey increased after intervention in the lian gong group. This variation was higher than that observed in the control group for the domains functional capacity, limitation by physical aspects and general health status, and also higher than that found after the intervention in the Vestibular Rehabilitation Group regarding pain. No differences were found in the Short Physical Performance Battery. CONCLUSIONS Based on the results presented, lian gong improves the quality of life of individuals with dizziness, without altering the functional capacity.


RESUMO OBJETIVO Avaliar os efeitos da prática do lian gong como estratégia de reabilitação na atenção primária à saúde sobre a qualidade de vida e capacidade funcional de pessoas com tontura. MÉTODOS Trata-se de ensaio clínico randomizado-controlado. Participaram 36 voluntários, com queixa de tontura ou vertigem sem a presença de sinais centrais, encaminhados pelo médico da atenção primária à saúde. Os indivíduos foram aleatoriamente alocados para as três condições experimentais: grupo lian gong (n = 11), grupo reabilitação vestibular (n = 11) e grupo controle (n = 14). As intervenções foram semanais, em grupo, com duração de 12 sessões. Os participantes foram avaliados antes e após a intervenção quanto à qualidade de vida pelo 36-Item Short Form Health Survey e quanto à capacidade funcional pelo Short Physical Performance Battery. RESULTADOS Observou-se aumento dos scores de todos os domínios do Short Form Health Survey após intervenção no grupo lian gong. Essa variação foi maior que a observada no grupo controle para os domínios capacidade funcional, limitação por aspectos físicos e estado geral de saúde, e também superior à encontrada após a intervenção grupo reabilitação vestibular no domínio dor. Não houveram diferenças no Short Physical Performance Battery. CONCLUSÕES Com base nos resultados apresentados, o lian gong melhora a qualidade de vida de indivíduos com tontura, sem alterar a capacidade funcional.

ABSTRACT

El vértigo es definido como la sensación de movimiento ilusorio del cuerpo o de los objetos que le rodean. Es una de las causas más comunes de consulta en los departamentos de emergencia, y 2 a 3% de la población mundial consulta anualmente por este síntoma. De acuerdo al compromiso vestibular en el oído interno o en el sistema nervioso central o ambos, puede clasificarse en vértigo periférico, central o de origen mixto, siendo la principal causa del periférico el vértigo posicional paroxístico benigno. La valoración semiológica y anamnesis es fundamental para el diagnóstico. En el examen físico inicial, la diferenciación de un vértigo de origen central de otro de origen periférico, puede realizarse mediante el análisis del nistagmo, la valoración del impulso cefálico y la desviación ocular, que se integran en un sistema denominado HINTS, por sus siglas en inglés (Head Impulse, Nystamus type, Test of Skew), y por la realización de pruebas que evalúen también la vía vestíbulo-cerebelosa. Además, la realización de una audiometría tonal, aumentaría la sensibilidad diagnóstica de 71 a 89% en la evaluación inicial. El diagnóstico apropiado es la base para el tratamiento y control de esta condición clínica en el mediano y largo plazo.


Vertigo is defined as an abnormal sensation of body motion or of its surrounding objects. It is a common chief complaint in emergency departments comprising 2 to 3% of these consultations worldwide. Vertigo is classified as peripheral or central, according to its origin, and can also be occasionally mixed, the most common cause of peripheral involvement being benign paroxysmal positional vertigo. The initial findings on clinical evaluation of patients are the clues for making a correct diagnosis. The differentiation between central and peripheral vertigo can be optimized by analysing nystagmus, by using the skew test and the head impulse test (HINTS), as also by performing the appropriate tests to evaluate the integrity of the vestibular-cerebellar pathway. In addition, tonal threshold audiometry could raise the diagnostic sensibility from 71 to 89% on initial approach. Appropriate diagnosis is the principal key for managing this clinical condition.

ABSTRACT

ABSTRACT Objective To describe and compare the vestibular findings most evident among the hereditary ataxias, as well as correlate their clinical features with the nervous structures affected in this disease. Methods Seventy-five patients were evaluated and underwent a case history, otorhinolaryngological and vestibular assessments. Results Clinically, the patients commonly had symptoms of gait disturbances (67.1%), dizziness (47.3%), dysarthria (46%) and dysphagia (36.8%). In vestibular testing, alterations were predominantly evident in caloric testing (79%), testing for saccadic dysmetria (51%) and rotational chair testing (47%). The presence of alterations occurred in 87% of these patients. A majority of the alterations were from central vestibular dysfunction (69.3%). Conclusion This underscores the importance of the contribution of topodiagnostic labyrinthine evaluations for neurodegenerative diseases as, in most cases, the initial symptoms are otoneurological; and these evaluations should also be included in the selection of procedures to be performed in clinical and therapeutic monitoring.


RESUMO Objetivo Descrever e comparar os achados vestibulares mais evidentes entre a ataxia hereditária, bem como correlacionar seus aspectos clínicos com o estudo das estruturas nervosas afetadas nesta doença. Métodos 75 pacientes foram avaliados e submetidos aos seguintes procedimentos: anamnese, avaliação otorrinolaringológica e vestibular. Resultados Clinicamente, os pacientes apresentaram sintomas de distúrbios da marcha (67,1%), tonturas (47,3%), disartria (46%) e disfagia (36,8%). No teste vestibular, as alterações foram predominantemente evidentes no teste calórico (79%), dismetria sacádicas (51%) e no teste rotatório (47%). A presença de alterações ocorreu em 87% dos pacientes. A maioria das alterações observadas foram da disfunção vestibular central (69,3%). Conclusão O estudo ressalta a importância da contribuição da avaliação labiríntica no topodiagnóstico para doenças neurodegenerativas, uma vez que, na maioria dos casos, os sintomas iniciais são otoneurológicos, e essas avaliações também devem ser incluídas na seleção de procedimentos a serem realizados no monitoramento clínico e terapêutico.

ABSTRACT

ABSTRACT Objective: To assess the effectiveness of balance exercises by means of virtual reality games in Parkinson's disease. Methods: Sixteen patients were submitted to anamnesis, otorhinolaryngological and vestibular examinations, as well as the Dizziness Handicap Inventory, Berg Balance Scale, SF-36 questionnaire, and the SRT, applied before and after rehabilitation with virtual reality games. Results: Final scoring for the Dizziness Handicap Inventory and Berg Balance Scale was better after rehabilitation. The SRT showed a significant result after rehabilitation. The SF-36 showed a significant change in the functional capacity for the Tightrope Walk and Ski Slalom virtual reality games (p < 0.05), as well as in the mental health aspect of the Ski Slalom game (p < 0.05). The Dizziness Handicap Inventory and Berg Balance Scale showed significant changes in the Ski Slalom game (p < 0.05). There was evidence of clinical improvement in patients in the final assessment after virtual rehabilitation. Conclusion: The Tightrope Walk and Ski Slalom virtual games were shown to be the most effective for this population.


RESUMO Objetivo: Verificar a eficácia dos exercícios de equilíbrio com realidade virtual (RVi) na doença de Parkinson.

ABSTRACT

Abstract Introduction: Health-related quality of life is used to denote that portion of the quality of life that is influenced by the person's health. Objectives: To compare the health-related quality of life of individuals with vestibular disorders of peripheral origin by analyzing functional, emotional and physical disabilities before and after vestibular treatment. Methods: A prospective, non randomized case-controlled study was conduced in the ENT Department, between January 2015 and December 2015. All patients were submitted to customize a 36 item of health survey on quality of life, short form 36 health survey questionnaire (SF-36) and the Dizziness Handicap Inventory for assessing the disability. Individuals were diagnosed with acute unilateral vestibular peripheral disorders classified in 5 groups: vestibular neuritis, Ménière Disease, Benign Paroxysmal Positional Vertigo, cochlear-vestibular dysfunction (other than Ménière Disease), or other type of acute peripheral vertigo (as vestibular migraine). Results: There was a statistical significant difference for each parameter of Dizziness Handicap Inventory score (the emotional, functional and physical) between the baseline and one month both in men and women, but with any statistical significant difference between 7 days and 14 days. It was found a statistical significant difference for all eight parameters of SF-36 score between the baseline and one month later both in men and women; the exception was the men mental health perception. The correlation between the Dizziness Handicap Inventory and the SF-36 scores according to diagnostics type pointed out that the Spearman's correlation coefficient was moderate correlated with the total scores of these instruments. Conclusion: The Dizziness Handicap Inventory and the SF-36 are useful, proved practical and valid instruments for assessing the impact of dizziness on the quality of life of patients with unilateral peripheral vestibular disorders.


Resumo Introdução: Qualidade de vida relacionada à saúde é usada para designar a parte da qualidade de vida que é influenciada pela saúde do indivíduo. Objetivos: Comparar a qualidade de vida relacionada à saúde de indivíduos com distúrbios vestibulares de origem periférica, analisar incapacidades funcionais, emocionais e físicas antes e após o tratamento vestibular. Método: Um estudo de caso-controle prospectivo, não randomizado, foi conduzido no Departamento de Otorrinolaringologia, entre janeiro de 2015 e dezembro de 2015. Todos os pacientes foram submetidos a uma pesquisa de saúde personalizada de 36 itens sobre qualidade de vida, ao formulário abreviado de avaliação de saúde 36 (SF-36) e ao Dizziness Handicap Inventory para avaliar a incapacidade. Os indivíduos foram diagnosticados com distúrbios vestibulares periféricos unilaterais agudos, classificados em cinco grupos: neurite vestibular, doença de Ménière, vertigem posicional paroxística benigna, disfunção cócleo-vestibular (exceto Doença de Ménière) ou outro tipo de vertigem periférica aguda (como enxaqueca vestibular). Resultados: Houve uma diferença estatisticamente significante para cada parâmetro de escore no Dizziness Handicap Inventory (emocional, funcional e físico) entre a avaliação basal e depois de um mês, tanto em homens quanto em mulheres, mas sem diferença estatística significativa entre sete dias e 14 dias. Foi encontrada uma diferença estatisticamente significante para todos os oito parâmetros do escore no SF-36 entre a avaliação basal e um mês mais tarde, tanto em homens quanto em mulheres; a exceção foi a percepção de saúde mental nos homens. A correlação entre Dizziness Handicap Inventory e o SF-36 de acordo com o tipo de diagnóstico mostrou que o coeficiente de correlação de Spearman foi moderado quando correlacionado com o escore total desses instrumentos. Conclusão: O Dizziness Handicap Inventory e o SF-36 demonstraram ser instrumentos úteis, práticos e válidos para avaliar o impacto da tontura na qualidade de vida de pacientes com distúrbios vestibulares periféricos unilaterais.

ABSTRACT

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.

ABSTRACT

Abstract Objective This study aimed to evaluate if hearing performance is a predictor of postural control in cochlear implant (CI) users at least six months after surgery. Methods Cross-sectional study including (CI) recipients with post-lingual deafness and controls who were divided into the following groups: nine CI users with good hearing performance (G+), five CI users with poor hearing performance (G−), and seven controls (CG). For each patient, computerized dynamic posturography (CDP) tests, a sensory organization test (SOT), and an adaptation test (ADT) were applied as dual task performance, with first test (FT) and re-test (RT) on the same day, including a 40–60 min interval between them to evaluate the short-term learning ability on postural recovery strategies. The results of the groups were compared. Results Comparing the dual task performance on CDP and the weighted average between all test conditions, the G+ group showed better performance on RT in SOT4, SOT5, SOT6, and CS, which was not observed for G− and CG. The G− group had significantly lower levels of short-term learning ability than the other two groups in SOT5 (p = 0.021), SOT6 (p = 0.025), and CS (p = 0.031). Conclusion The CI users with good hearing performance had a higher index of postural recovery when compared to CI users with poor hearing performance.


Resumo Objetivo O presente estudo teve por objetivo avaliar se o desempenho auditivo é preditor de controle postural em usuários de IC pelo menos seis meses após a cirurgia. Método Estudo transversal que consistiu em recipientes de implante coclear (IC) com surdez pós-lingual e controles, que foram divididos nos seguintes grupos: nove usuários de IC com bom desempenho auditivo (G+), cinco usuários de usuários de IC com desempenho auditivo insatisfatório (G-) e sete controles (GC). Aplicamos os testes de posturografia dinâmica computadorizada (PDC), de organização sensitiva (TOS) e de adaptação (TAd) como desempenho de dupla tarefa, primeiro teste (PT) e reteste (RT) no mesmo dia, com intervalo de 40-60 minutos entre testes, com o objetivo de avaliar a capacidade de aprendizado em curto prazo nas estratégias de recuperação postural. Comparamos os resultados dos testes. Resultados Na comparação do desempenho de dupla tarefa no teste PDC e a média ponderal entre todas as condições de teste, o grupo G+ demonstrou melhor desempenho no RT nos TOS4, TOS5, TOS6 e EC, o que não foi observado para os grupos G- e GC. O grupo G- obteve níveis significantemente mais baixos de capacidade de aprendizado em curto prazo vs. outros dois grupos no TOS5 (p = 0,021), TOS6 (p = 0,025) e EC (p = 0,031). Conclusão Usuários de IC com bom desempenho auditivo tiveram índice melhor de recuperação postural, quando comparados com usuários de IC com desempenho auditivo insatisfatório.

ABSTRACT

Abstract Introduction The symptoms associated with chronic peripheral vestibulopathy exert a negative impact on the independence and quality of life of these individuals, and many individuals continue to suffer from these symptoms even after conventional vestibular rehabilitation. Objective To evaluate the acute effect of an anchor system for balance evaluation of patients with chronic dizziness who failed to respond to traditional vestibular rehabilitation. Methods Subjects over 50 years of age, presenting with chronic dizziness and postural instability of peripheral vestibular origin, participated in the study. The limit of stability was evaluated in three positions using the Balance Master® system: Position 1, standing with the arms along the body; Position 2, standing with the elbows bent at 90º (simulating holding the anchors); and Position 3, with the elbows bent at 90º holding the anchors. The variables of movement latency, endpoint excursion and directional control of movement were evaluated. Results Using the anchor system, significant reduction of time in the response at the beginning of the movement compared to Position 1 (p < 0.05); increased endpoint excursion in the left lateral direction compared to Position 1 (p < 0.05); and more directional control of movement in the anterior and posterior directions (p < 0.05) compared to the other positions, were found. Conclusion While using the system anchor, individuals with chronic peripheral vestibulopathy showed an immediate improvement in the stability limit in relation to the movement latency, endpoint excursion, and directional control of movement variables, suggesting that the haptic information aids postural control.


Resumo Introdução Os sintomas associados à vestibulopatia periférica crônica têm impacto negativo na independência e qualidade de vida dos indivíduos e muitos deles continuam a sofrer desses sintomas, mesmo depois de ter passado pela reabilitação vestibular convencional. Objetivo Avaliar o efeito agudo de um sistema de ancoragem para avaliação do equilíbrio de pacientes com tontura crônica que não responderam à reabilitação vestibular tradicional. Método Participaram do estudo indivíduos com mais de 50 anos que se apresentaram com tontura crônica e instabilidade postural de origem vestibular periférica. O limite de estabilidade foi avaliado em três posições, com o uso do sistema Balance Master®: Posição 1, de pé com os braços pendentes ao longo do corpo; Posição 2, de pé com os cotovelos flexionados em 90º (simulando a posição de segurar as âncoras); e Posição 3, com os cotovelos flexionados em 90º e segurando as âncoras. Foram avaliadas as variáveis de latência de movimento, o ponto final da excursão e o controle direcional do movimento. Resultados Com o uso do sistema de âncoras, ocorreu redução significante no tempo de resposta no início do movimento em comparação com a Posição 1 (p < 0,05); aumento no ponto final da excursão na direção lateral esquerda, em comparação com a Posição 1 (p < 0,05); e mais controle direcional do movimento nas direções anterior e posterior (p < 0,05), em comparação com as demais posições. Conclusão Enquanto usavam o sistema de âncoras, os indivíduos com vestibulopatia periférica demonstraram melhoria imediata no limite da estabilidade em relação às variáveis latência de movimento, ponto final da excursão e controle direcional do movimento. Isso sugere que a informação háptica auxilia no controle postural.

ABSTRACT

ABSTRACT INTRODUCTION: Dizziness is among the most common complaints in the elderly population. OBJECTIVE: To determine the sociodemographic and clinical-functional profiles of institutionalized elderly people related to dizziness. METHODS: Cross-sectional prospective study with institutionalized elderly people aged 60 or more years. A questionnaire on sociodemographic and clinical-functional characteristics was applied, and an anamnesis of occurrence of dizziness was held, as well as the Dizziness Handicap Inventory questionnaire. RESULTS: 48.9% of the elderly subjects had dizziness. The mean numbers of diseases and medications associated with dizziness were, respectively, 4.5 diseases and 7.8 medications. We found a significant association between the occurrence of dizziness and diseases of the musculoskeletal system, sub-connective tissue and genitourinary system, as well as the use of medications for the musculoskeletal system. The scores for handicap degree in functional DHI were significantly higher among elderly subjects who needed walking aids, who had suffered falls, and those manifesting anxiety. CONCLUSION: Our sample included subjects of advanced age, primarily women, who were institutionalized less than five years, with multiple diseases and polypharmacy users. They presented long-standing short-duration mixed dizziness, that occurred more than once a month and affected mainly the functional aspect.


RESUMO INTRODUÇÃO: A tontura está entre as queixas mais comuns da população idosa. OBJETIVO: Determinar os perfis sociodemográfico e clínico-funcional de idosos institucionalizados com relação à tontura. MÉTODO: Estudo prospectivo transversal, com idosos institucionalizados com ≥ 60 anos de idade. Foi aplicado um questionário referente às características sociodemográficas e clínico-funcionais, assim como foi feita anamnese sobre a ocorrência de tontura, e aplicado o questionário Dizziness Handicap Inventory. RESULTADOS: 48,9% dos idosos apresentaram tontura. As médias do número de doenças e medicamentos associados à tontura foram, respectivamente, 4,5 doenças e 7,8 medicamentos. Houve associação significativa entre ocorrência de tontura e doenças do sistema osteomuscular, do tecido subconjuntivo e do aparelho geniturinário, bem como uso de medicamentos para o sistema musculoesquelético. Os escores do grau de handicap no DHI funcional foram significativamente maiores para os idosos que necessitavam de auxílio à marcha, para os que tiveram queda e para os que apresentaram ansiedade.

ABSTRACT

INTRODUCTION: Persistent postural-perceptual dizziness is the dizziness that lasts for over three months with no clinical explanation for its persistence. The patient's motor response pattern presents changes and most patients manifest significant anxiety. OBJECTIVE: To evaluate the clinical characteristics of patients with persistent postural and perceptual dizziness. METHODS: statistical analysis of clinical aspects of patients with persistent postural-perceptual dizziness. RESULTS: 81 patients, average age: 50.06 ± 12.16 years; female/male ratio: 5.7/1; main reasons for dizziness: visual stimuli (74%), body movements (52%), and sleep deprivation (38%). The most prevalent comorbidities were hypercholesterolemia (31%), migraine headaches (26%), carbohydrate metabolism disorders (22%) and cervical syndrome (21%). DHI, State-Trait Anxiety Inventory - Trait, Beck Depression Inventory, and Hospital Anxiety and Depression Scale questionnaires were statistically different (p < 0.05) when compared to controls. 68% demonstrated clinical improvement after treatment with serotonin reuptake inhibitors. CONCLUSION: Persistent postural-perceptual dizziness affects more women than men, with a high associated prevalence of metabolic disorders and migraine. Questionnaires help to identify the predisposition to persistent postural-perceptual dizziness. The prognosis is good with adequate treatment. .


INTRODUÇÃO: A denominação tontura postural-perceptual persistente (TPPP) é atribuida à tontura que se mantém por mais de 3 meses em pacientes, sem que exista justificativa clínica para a sua persistência. A maioria dos pacientes possui perfil ansioso ou experimenta alto grau de ansiedade no início dos sintomas. O padrão de resposta motora apresenta-se alterado, com hipervigilância e hipersensibilidade a estímulos visuais e de movimento. OBJETIVO: Avaliar as características clínicas de pacientes com diagnóstico de TPPP. MÉTODO: Análise dos aspectos clínicos de pacientes do ambulatório de TPPP e quantificação do perfil ansioso ou depressivo. RESULTADOS: Foram avaliados 81 pacientes, com média de idade de 50,06 ± 12,16 anos; relação mulher/homem de 5,7/1; principais gatilhos para tontura: estímulos visuais (74%), movimentos corporais (52%) e privação de sono (38%). As comorbidades mais prevalentes foram hipercolesterolemia (31%), migrânea (26%), distúrbios do metabolismo do açúcar (22%) e síndrome cervical (21%). Os questionários DHI, STAI-Traço, Beck para depressão e HADS foram estatisticamente diferentes (P < 0,05) entre pacientes e controles. 68% de melhora clínica com o uso de inibidores da recaptação da serotonina. CONCLUSÃO: TPPP acomete principalmente as mulheres, sendo alta a associação com distúrbios metabólicos e migrânea. Os questionários auxiliam na identificação da predisposição à TPPP. Há bom prognóstico com o tratamento adequado. .

ABSTRACT

INTRODUCTION: Patients with vestibular hypofunction, a typical finding in peripheral vestibular disorders, show body balance alterations. OBJECTIVE: To evaluate the postural control of patients with vertigo and unilateral vestibular hypofunction. METHOD: This is a clinical cross-sectional study. Twenty-five patients with vertigo and unilateral vestibular hypofunction and a homogeneous control group consisting of 32 healthy individuals were submitted to a neurotological evaluation including the Tetrax Interactive Balance System posturography in eight different sensory conditions. RESULTS: For different positions, vertiginous patients with unilateral vestibular hypofunction showed significantly higher values of general stability index, weight distribution index, right/left and tool/heel synchronizations, Fourier transformation index and fall index than controls. CONCLUSION: Increased values in the indices of weight distribution, right/left and tool/heel synchronizations, Fourier transformation and fall risk characterize the impairment of postural control in patients with vertigo and unilateral vestibular hypofunction. .


INTRODUÇÃO: Pacientes com hipofunção vestibular, achado típico em vestibulopatias periféricas, apresentam alterações de equilíbrio corporal. OBJETIVO: Avaliar o controle postural de pacientes vertiginosos com hipofunção vestibular unilateral. MÉTODO: Trata-se de um estudo clínico transversal. No total, 25 pacientes vertiginosos com hipofunção vestibular unilateral e um grupo controle homogêneo de 32 indivíduos hígidos foram submetidos à avaliação otoneurológica, incluindo a posturografia do Tetrax Interactive Balance System em oito diferentes condições sensoriais. RESULTADOS: O grupo experimental apresentou valores significantemente maiores do que o grupo controle quanto ao índice de estabilidade geral, índice de distribuição de peso, índice de sincronização da oscilação postural direita/esquerda e dedos/calcanhar, faixas de frequência de oscilação postural (F1, F2-F4, F5-F6, F7-F8) e índice de risco de queda, em diferentes condições sensoriais. CONCLUSÃO: Alterações de distribuição de peso, sincronização da oscilação postural direita/esquerda e dedos/calcanhares, faixas de frequência de oscilação postural e do índice de risco de queda caracterizam o comprometimento do controle postural em pacientes vertiginosos com hipofunção vestibular unilateral. .

ABSTRACT

Background: The Vestibular Disorders Activities of Daily Living Scale (VADL) is considered an important subjective assessment to evaluate patients suffering from dizziness and imbalance. Although frequently used, its metric characteristics still require further investigation. Objective: This paper aims to analyze the psychometric properties of the Brazilian version of the VADL in an elderly population. Method: The sample comprises patients (≥65 years old) with chronic dizziness resulting from vestibular disorders. For discriminant analysis, patients were compared to healthy subjects. All subjects answered the VADL-Brazil by interview. To examine the VADL validity, patients filled out the Dizziness Handicap Inventory (DHI) and the ABC scale and were tested on the Dynamic Gait Index (DGI). To evaluate the VADL responsiveness, 20 patients were submitted to rehabilitation. Results: Patients (n=140) had a VADL total score of 4.1±1.6 points. Healthy subjects scored significantly less than patients in all the subscales and in the VADL total score. The VADL-Brazil was weakly correlated with the DHI and moderately to the ABC scale and the DGI. Instead of the original 3 subscales, factor analysis resulted in 6 factors. The VADL was capable of detecting changes after rehabilitation, which means that the instrument has responsiveness. Conclusions: This study provided more data about the psychometric properties and usefulness of the VADL-Brazil. The use of such a reliable and valid instrument increases the knowledge about disability in patients with vestibular disorders. .

ABSTRACT

The authors advocate a modernization of the neurologic exam with regard to the evaluation of static equilibrium through the application of some easily performed and interpreted bedside maneuvers like the Clinical Test of Sensory Integration and Balance - modified and the Functional Reach Test. The authors also believe that these and other assessments, such as that of the risk of falling for elderly patients, should be incorporated into the routine neurological examination.


Os autores advogam a modernização do exame neurológico no que diz respeito à pesquisa do equilíbrio estático, por meio da aplicação de algumas manobras de beira-de-leito fáceis de serem executadas e interpretadas, tais como o Teste Clínico de Integração Sensorial e Equilíbrio-modificado e o Teste do Alcance Funcional. Os autores também acreditam que estes e outros testes visando avaliação de risco de queda em pacientes idosos devem fazer parte do exame neurológico de rotina.

ABSTRACT

The authors propose that the neurological exam needs reevaluation with respect to the dynamic balance test (walking). Validated tests such as: preferred and maximum gait speed, dynamic gait index, five-times-sit-to-stand test, timed up & go cognitive and manual, should be part of the neurological examination routine. In the neurological exam of older patients, these same bedside tests bring the plus of evaluation the risk of occasional falling.


Os autores propõem que o exame neurológico tradicional seja reavaliado no que diz respeito ao exame do equilíbrio dinâmico (marcha). Testes validados tais como: velocidade da marcha - preferencial e máxima; índice dinâmico da marcha, teste senta-levanta cinco vezes e o tempo levanta-e-anda cognitivo e manual, deveriam fazer parte do exame neurológico de rotina. Na avaliação neurológica dos pacientes idosos, esses mesmos testes à beira do leito trazem benefício adicional ao aferir o risco de queda ocasional.

ABSTRACT

OBJECTIVE: To evaluate balance control with Balance Rehabilitation Unit (BRU TM) posturography in patients with multiple sclerosis (MS). METHOD: A cross controlled study was performed including 39 relapsing-remitting multiple sclerosis patients with scores less than or equal to 4 in the Expanded Disability Status Scale (EDSS), and a homogeneous control group consisting of 65 healthy individuals, matched by the age and gender. The experimental group was distributed according to the EDSS scale scores in 0-2.5 and 3-4. To assess the vestibular system function, the patients underwent a neurotological evaluation, including posturography of the Balance Rehabilitation Unit (BRU TM). RESULTS: Statistically significant differences were observed when comparing the values of the sway velocity and the ellipse area of the MS 0-2.5 group with the control and the MS 3-4 group with the control. A statistically significant difference was verified between the MS 0-2.5 and the MS 3-4 groups in the condition 3 ellipse area values. CONCLUSION: The evaluation of the balance control with posturography of Balance Rehabilitation Unit (BRU TM) enables the identification of abnormalities of the sway velocity and confidential ellipse in patients with relapsing-remitting multiple sclerosis.
