ABSTRACT

La terapia de rehabilitación vestibular es el tratamiento con mayor evidencia en la recuperación para la mayoría de los trastornos de equilibrio. En los casos que presentan una alteración estable del procesamiento central del equilibrio, o mixta, es decir, acompañada de una alteración a nivel del sistema nervioso periférico, la terapia de rehabilitación vestibular no se excluye como tratamiento. No obstante, los progresos suelen ser limitados y requieren de una mayor cantidad de sesiones. En este trabajo analizaremos un caso mixto, un paciente con síndrome de núcleo fastigial y el vértigo posicional paroxístico benigno (VPPB), desde la pesquisa y evaluación hasta el tratamiento y alta, en el Hospital Clínico Universidad de Chile.


Vestibular rehabilitation therapy is the treatment with the greatest evidence of recovery for most balance disorders. In the cases that have a loss of central balance processing, or mixed, that is, stable accompanied by a disorder of the peripheral nervous system the vestibular rehabilitation therapy is not excluded as a treatment; however, progress is usually limited and requires a greater number of sessions. In this work we will analyse a mixed case, a patient with nucleus fastigial syndrome and a benign paroxysmal positional vertigo, from the investigation and evaluation to the treatment and discharge, at the Hospital Clínico Universidad de Chile.

ABSTRACT

RESUMO Esta pesquisa teve como objetivo caracterizar o efeito da reabilitação vestibular (RV) sobre o ganho do reflexo vestíbulo-ocular (RVO), a ocorrência das sacadas compensatórias, bem como sobre o equilíbrio corporal e a qualidade de vida, em três pacientes com hipofunção vestibular periférica. Trata-se de um estudo descritivo. Participaram da pesquisa três pacientes do gênero feminino, duas com 55 anos e uma com 67 anos, com diagnóstico médico de disfunção vestibular periférica. As participantes foram submetidas à anamnese, questionário Dizziness Handicap Inventory (DHI), avaliação clínica do equilíbrio corporal e ao Vídeo Teste do Impulso Cefálico (vHIT), pré e após RV. A RV foi aplicada de forma personalizada, baseada no protocolo de Cawthorne e Cooksey, associada a estímulos de realidade virtual. Após a RV, observou-se a redução da média do escore total do DHI, sugestivo da diminuição na restrição de participação. Na avaliação clínica do equilíbrio obtiveram-se resultados dentro da normalidade para as provas alteradas, pré RV. Quanto ao vHIT, constatou-se aumento do ganho do RVO para os canais semicirculares anteriormente afetados, condizente com padrões de normalidade, e extinção ou diminuição de ocorrência das sacadas compensatórias, nos três casos avaliados. O aumento do ganho do RVO e a extinção ou redução das sacadas compensatórias, após a RV, evidenciam sinais sugestivos de compensação vestibular. Esses resultados mostraram-se compatíveis com o aumento da estabilidade postural e menor restrição da qualidade de vida. Os achados, em conjunto, demonstram o benefício proporcionado pela RV nos três casos avaliados.


ABSTRACT The purpose of this research is to characterize the vestibular rehabilitation (VR), vestibulo-ocular reflex (VOR) gain, the occurrence of compensatory saccades, the static and dynamic balance, and the impact on quality of life in three patients with peripheral vestibular hypofunction. This is a descriptive study, approved by the ethics in research committee, under number 4,462.519. Three female patients participated in the study, two aged 55 and one aged 67, with a medical diagnosis of peripheral vestibular dysfunction. The participants underwent anamnesis, Dizziness Handicap Inventory (DHI) questionnaire, clinical assessment of postural balance and Video Head Impulse Test (vHIT), pre and post VR. The VR was applied in a personalized manner, based on the Cawthorne and Cooksey protocol, associated with virtual reality stimuli. After VR, a reduction in the total score average of DHI was observed, suggesting a decrease in participation restriction. The clinical balance assessment results were within the normal range for the altered tests, pre VR. In the three evaluated cases, vHIT showed increased RVO gain for the previously affected semicircular ducts (SCDs), compatible with normality standards, and reduction or extinction in the occurrence of compensatory saccades. The increase in VOR gain and the reduction or suppression of compensatory saccades after VR are suggestive signs of vestibular compensation. These results were compatible with increased postural stability and less restricted quality of life. These findings demonstrate the benefit provided by VR in the three evaluated cases.

ABSTRACT

ABSTRACT Objective: to verify, in the literature, the proposals to rehabilitate the vestibular function, so as to propose a training program for body balance for children. Methods: this article sought studies that proposed to rehabilitate or train body balance in the Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed) and Scientific Electronic Library Online (SCIELO) databases, in addition to digital sources from Brazilian public universities. As descriptors, the terms "rehabilitation", "balance" and "child" were used, combined with the Boolean operator AND. The variables analyzed were: public submitted to the intervention, number of subjects and age group, number and frequency of sessions, number and/or time of execution of the exercise, duration of the session and the program. Results: 17 (60.74%) articles were Brazilian, 14 (50%) used the Cawthorne and Cooksey protocol, 9 (32.14%) studied children, and the majority (67.85%) organized the program in weeks. A body balance training program, stimulating the three body balance systems, consisting of 30-minute sessions twice a week for 7 weeks, totaling 14 sessions, was developed. Conclusion: the analysis of the variable related to the protocol/strategy to rehabilitate the vestibular function indicated that no study proposed the stimulation of the three body balance systems, with no standardization for children, adults and the elderly. A vestibular function rehabilitation program was developed for children, with stimulation of these three systems, expanding the therapeutic possibilities in this area.


RESUMO Objetivo: verificar, na literatura, as propostas para reabilitar a função vestibular e propor um programa de treinamento do equilíbrio corporal para o público infantil. Metodos: buscou-se estudos propondo reabilitar/treinar o equilíbrio corporal nas bases de dados MEDLINE/PubMed e SCIELO, além das fontes digitais de universidades públicas brasileiras. Descritores utilizados: rehabilitation, balance e child, combinando-os com o operador boleano AND. Analisou-se as variáveis: público submetido à intervenção, número de sujeitos e faixa etária, número e periodicidade das sessões, número e/ou tempo de execução do exercício, duração da sessão e do programa. Resultados: 17 eram brasileiros, 14 utilizaram o protocolo de Cawthorne e Cooksey, nove estudaram crianças, a maioria organizou o programa em semanas. Elaborou-se um programa de treinamento do equilíbrio corporal que estimula os três sistemas do equilíbrio corporal, constituido por sessões de 30 minutos duas vezes por semana, durante 7 semanas, totalizando 14 sessões. Conclusão: a análise da variável relativa ao protocolo/estratégia para reabilitar a função vestibular indicou que nenhum estudo propôs a estimulação dos três sistemas do equilíbrio corporal, não havendo padronização para os públicos infantil, adulto e idoso. Elaborou-se um programa de reabilitação da função vestibular para crianças, com estimulação destes três sistemas, ampliando as possibilidades terapêuticas.

ABSTRACT

Resumen Se presenta una reflexión producto de la introducción del paradigma de tareas dobles en el abordaje terapéutico en un caso de vestibulopatía unilateral periférica. Se aplicaron pautas de autovaloración de la discapacidad y riesgo de caídas, complementándose con una completa evaluación del equilibrio funcional y la marcha. Se planificó una terapia personalizada, jerarquizándose objetivos con un criterio funcional. Se incorporó el paradigma de tareas dobles, incluyéndose tareas cognitivas simples a la terapia tradicional de rehabilitación vestibular, con el fin de reducir la influencia cortical sobre la ejecución motora, potenciar la ganancia y funcionalidad de los reflejos remanentes, estimular funciones cognitivas superiores y potenciar procesos atencionales subyacentes, necesarios para lograr la compensación. Los resultados de la reevaluación mostraron una evolución favorable, con remisión de la sintomatología, disminución significativa de los puntajes obtenidos en las diferentes pautas empleadas y una mejoría subjetiva en el equilibrio y marcha funcional después de la terapia. Lo anterior se asoció a la recuperación de la autonomía e independencia para la ejecución de actividades diarias, incidiendo favorablemente en la calidad de vida de la paciente. Los hallazgos confirman los beneficios del programa de rehabilitación vestibular diseñado. Se requieren estudios adicionales, orientados a evidenciar y corroborar el impacto específico de la incorporación del paradigma de tareas dobles en la rehabilitación de los trastornos del equilibrio y especialmente, en procesos de estimulación o rehabilitación vestibular en adultos mayores.


Abstract This article presents the analysis and reflections evoked from an experience in vestibular rehabilitation with the introduction of the paradigm of dual task in a unilateral peripheral vestibulopathy case. First, disability self-assessment guidelines, risk of falls scales and assessment tools of functional balance and gait were applied in order to determine the main symptoms and the main difficulties observed. Afterwards, a personalized therapy was planned, in which work objectives were hierarchized based on a functional criterion, introducing "dual-task" strategies as tools for diminish cortical influence on motor performances, allowing the automation of the required task; enhance the gain and functionality of the remaining reflexes, especially vestibulo ocular and vestibulospinal reflex and stimulate superior cognitive functions and underlying attentional processes, necessary to achieve central compensation. The final assessment showed a favorable evolution, with a significant decrease in the after-therapy scores obtained in fear of falling and disability self-perception protocols, before and after therapy and, finally, an improvement in functional balance and gait, through the pre and post therapy performance in the timed up and go and assessment of unipedal stand tests. This allowed the patient to regain her autonomy and independence in daily life activities improving her quality of life, confirming the benefits of the designed vestibular rehabilitation program. However, more studies are needed to corroborate the specific contribution of the dual-task paradigm in vestibular rehabilitation and specially, in vestibular stimulation or rehabilitation processes in older adults.

ABSTRACT

La terapia vestibular ha mostrado una evolución constante hacia la práctica basada en evidencia principalmente en los últimos años, sin embargo, actualmente no existe consenso sobre la dosificación de tratamiento necesaria para generar resultados deseados en los usuarios. Por ello, el presente estudio pretende analizar la evidencia científica sobre la dosificación de tratamiento en la terapia vestibular para patologías vestibulares periféricas y su impacto en la práctica clínica. Se realizó una búsqueda bibliográfica en las bases de datos PubMed y Cochrane Library de acuerdo a términos claves. Los estudios incluidos fueron ensayos clínicos, revisiones sistemáticas y metaanálisis, publicados desde el año 2009 y realizado en seres humanos. Se encontraron 60 artículos relacionados con los términos claves utilizados, de los cuales 52 fueron eliminados por cumplir con los criterios de exclusión. Existe escasa literatura sobre la dosificación de tratamiento en terapia vestibular, demostrando formatos de aplicación muy disímiles. Resulta complejo establecer estándares para la dosis terapéutica producto de la heterogeneidad de las patologías vestibulares.


Recently, vestibular rehabilitation therapy has shown constant development towards evidence-based practice, however, at the present time, there is lack of consensus about treatment dosage needed to produce the desired results for the users. Therefore, the present study aimed to analyze scientific evidence relating to treatment dosage of vestibular rehabilitation therapy for peripheral vestibular pathologies, and its impact on clinical practice. We conducted a bibliographic search in PubMed, and Cochrane Library according to previously defined MeSH terms. Included studies were clinical trials, systematic revisions, and meta-analyses, that were published since 2009, and conducted with human participants. The initial search yielded 60 articles related to the MeSH terms chosen, from which 52 were eliminated according to exclusion criteria. There is a scarce number of scientific articles regarding treatment dosage, and also a heterogeneous application format. It is a complex task to establish standards regarding therapeutic doses, mainly due to the heterogeneity of vestibular pathologies.

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 Introducción: Las alteraciones del sistema vestibular como la hipofunción vestibular unilateral, predisponen al usuario a sufrir caídas alterando así su confianza. Objetivo: Determinar el impacto de la rehabilitación vestibular en el riesgo de caídas y el grado de confianza en mujeres con hipofunción vestibular unilateral. Material y método: Se realiza estudio prospectivo en 20 pacientes de género femenino mayores de 60 años con diagnóstico de patología vestibular periférica. Se evalúa el riesgo de caídas con escala Tinetti y el grado de confianza al realizar actividades de la vida diaria por medio de la escala ABC (Activities-specific Balance Confidence), antes y después de realizar terapia de rehabilitación vestibular (RV). Resultados: Las dos variables estudiadas Tinetti y escala ABC demostraron mejoras significativas en la mayoría de las pacientes, demostrando que a medida que aumenta el grado de confianza disminuye el riesgo de caídas. Conclusión: Los resultados obtenidos de este estudio sugieren que la terapia de RV es eficiente en mejorar el riesgo de caídas y favorecer el aumento de confianza en las actividades de la vida diaria en el grupo de pacientes estudiadas.


ABSTRACT Introduction: Changes in the vestibular system, such as unilateral vestibular hypo-function, predispose the user to suffer falls, thus altering his confidence. Aim: To determine the impact of vestibular rehabilitation on the risk of falls and the degree of confidence in women with unilateral vestibular hypofunction. Material and method: A prospective study was conducted in 20 female patients over 60 years of age with a diagnosis of peripheral vestibular pathology. The risk of falls with a Tinetti scale and the degree of confidence in carrying out activities of daily living are evaluated through the ABC scale (Activities-specific Balance Confidence), before and after performing vestibular rehabilitation therapy (VRT). Results: The two variables studied, Tinetti and ABC scale showed significant improvements in most of the patients, demonstrating that as the degree of confidence increases the risk of falls decreases. Conclusion: The results obtained from this study suggest that VRT is efficient in improving the risk of falls and favoring an increase in confidence in the activities of daily life in the group of patients studied.

ABSTRACT

RESUMEN Los sistemas vestibular, visual y somatosensorial coordinan el control postural y se adaptan a las actividades cotidianas en diferentes contextos, sin embargo, cuando existe un cuadro clínico con sintomatología vestibular, las ponderaciones de estos sistemas cambian mayoritariamente al sistema visual, creando una dependencia visual. El cerebelo, que es el principal encargado de generar una compensación vestibular en casos de hipofunción vestibular, juega un rol destacado en el aprendizaje motor generando comportamientos adaptativos que se transforman en puntos claves en la rehabilitación vestibular. Este artículo pretende exponer lo que la literatura informa en relación a la dependencia visual en pacientes con hipofunción vestibular.


ABSTRACT The vestibular, visual and somatosensory systems coordinate postural control and adapt to daily activities in different contexts, however, when there is a clinical picture with vestibular symptoms, the weights of these systems change mainly to the visual system, creating a visual dependence. The cerebellum, which is the main responsible for generating vestibular compensation in cases of vestibular hypofunction, plays a prominent role in motor learning generating adaptive behaviors that become key points in vestibular rehabilitation. This article aims to expose what the literature reports in relation to visual dependence in patients with vestibular hypofunction.

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

Introducción: el implante coclear (IC) se ha convertido en el tratamiento más efectivo para la hipoacusia neurosensorial severa-profunda. En los últimos años se han ampliado sus indicaciones, especialmente los casos bilaterales. Es por ello que en la comunidad otológica surge el interrogante de cómo puede afectar a la función vestibular la inserción de un array de electrodos intracocleares. Material y método: Estudio descriptivo, de tipo longitudinal, entre diciembre de 2013 y julio de 2016. Se realizó una revisión de 92 historias clínicas de pacientes que se sometieron a implante coclear en el mismo centro por el mismo equipo y cumplían criterios de inclusión. Resultados: De los 92 pacientes evaluados en el preoperatorio se observaron: Normofunción vestibular bilateral: 56 pacientes (60,8%), Hipofunción vestibular bilateral: 13 pacientes (14,1%), Hipofunción vestibular unilateral: 21 pacientes (22,8%). De los 46 oídos evaluados pre y post IC, un 14,8% (7 pacientes) presentaron hipofunción vestibular post IC, con normofunción previa. Solo 2 pacientes del total de la muestra presentaron sintomatología vestibular severa, con hipovalencias objetivadas en el post operatorio. Conclusiones: Se recomienda evaluar la función vestibular periférica en todos los pacientes candidatos a implante coclear, ya que de no existir otras consideraciones podría ser de utilidad a la hora de definir el lado a implantar.


Introduction: cochlear implant (IC) has become the most effective treatment for severe-deep neurosensory hearing loss. In recent years, indications have been extended, especially bilateral cases. This is why in the otological community the question arises as to how insertion of an array of intracochlear electrodes can affect the vestibular function. Material and method: A descriptive longitudinal study between december 2013 and july 2016. A review of 92 clinical records of patients who underwent cochlear implantation at the same center by the same team and met inclusion criteria were performed. Results: Of the 92 patients evaluated in the preoperative period, bilateral vestibular normobility: 56 patients (60.8%), bilateral vestibular hypofunction: 13 patients (14.1%), unilateral vestibular hypofunction: 21 patients (22.8%). Of the 46 ears assessed pre- and post-IC, 14.8% (7 patients) presented vestibular hypofunction post-IC, with previous normofunction. Only 2 patients from the total sample had severe vestibular symptoms, with postoperative hypovalences. Conclusions: It is recommended to evaluate the peripheral vestibular function in all patients candidates for cochlear implants since, if there were no other considerations, it might be useful to define the side to be implanted.

ABSTRACT

A tontura é considerada pela área médica, como um problema de saúde pública. Entender os distúrbios do equilíbrio corporal, como a limitação de um dos sistemas fundamentais para a sobrevivência do indivíduo, ajuda a compreender a importância e a necessidade de uma abordagem diagnóstica rápida e precisa. A valorização de sinais encontrados na avaliação vestibular, e da queixa do paciente, é fundamental para o diagnóstico, sendo de extrema importância o encaminhamento para avaliação exploratória do sistema vestibular, para que medidas terapêuticas personalizadas sejam adotadas. A reabilitação vestibular (RV) é um recurso terapêutico realizado por meio de exercícios que visam melhorar a interação vestíbulo-visual durante a movimentação cefálica, e ampliar a estabilidade postural estática e dinâmica nas condições que produzem informações sensoriais conflitantes. Objetivo: Verificar a eficácia de um protocolo de procedimentos terapêuticos de RV em grupo, aplicado em indivíduos com queixas vestibulares, considerando as variáveis: gênero, idade, presença de zumbido e influência da localização do comprometimento do sistema vestibular. Material e métodos: Estudo descritivo e retrospectivo, realizado a partir da análise de prontuários de 151 pacientes atendidos na DSA do HRAC-USP. A casuística foi delimitada a partir da análise de prontuários de pacientes de ambos os gêneros, com idade entre 10 a 88 anos. Os critérios de inclusão foram: queixas vestibulares, ter realizado a VENG pré RV em grupo, ter respondido ao Dizziness Handicap Inventory (DHI) e a Escala Visual Analógica (EVA), para os sintomas de tontura e zumbido, nas etapas pré e pós intervenção. A RV foi composta por 13 sessões de aproximadamente 60 minutos, seguindo protocolo especifico elaborado para a RV em grupo. O tratamento estatístico foi composto pelos testes Teste T, McNemar, Friedmann, Qui-Quadrado, Fisher, Binominal, Kolmogorov-Smirnov e Testes Wilcoxon. Foi adotado valor de significância (p) igual ou menor que 0,05. Resultados: Na comparação entre os resultados do DHI obtidos nas etapas pré e pós RV houve diferença para todos os aspectos, tanto a pontuação total como para a classificação por grau (p=0,001). Na análise do EVA houve diferença quanto ao desconforto da tontura (valor de p variou de 0,000 a 0,092), quanto ao desconforto relacionado ao zumbido (p=0,001). Houve diferença na comparação da avaliação vestibular por meio da VENG antes e depois da RV (p=0,003). Não houve correlação entre idade (p=0,610) e efetividade da RV porém houve correlação com o gênero (p=0,028). Houve diferença entre os resultados da VENG na comparação entre as etapas pré e pós RV em grupo (p=0,001). Na correlação da EVA com as variáveis, houve correlação com o gênero feminino (p=0,000), com todas as faixas etárias, exceto a de 10 a 20 anos (p=0,125) de 21 a 90 anos, e com o comprometimento vestibular periférico (p=0,000). Conclusão: O protocolo de RV em grupo, aplicados em pacientes com queixas vestibulares foi eficaz para a queixa de tontura e zumbido, independente da idade. O gênero feminino apresentou mais benefícios com a RV do que o gênero masculino. A RV foi eficaz para todos os tipos de comprometimento vestibular, inclusive nos achados identificados como normais.(AU)


Dizziness is considered by the medical field as a public health problem. Understanding body balance disorders, such as limiting one of the fundamental systems for individual survival, helps to understand the importance and necessity of a quick and accurate diagnostic approach. The evaluation of signs found in the vestibular evaluation, and the patient's complaint, is fundamental for the diagnosis, being extremely important the exploratory evaluation of the vestibular system, so that therapeutic therapeutic measures are adopted. Vestibular Rehabilitation (VR) is a therapeutic resource performed through exercises that aim to improve vestibulovisual interaction during head movement and to increase static and dynamic postural stability in conditions that produce conflicting sensory information. Aim: To verify the efficacy of a group VR therapeutic protocol, applied to individuals with vestibular complaints, considering the following variables: gender, age, tinnitus and influence of the location of vestibular system impairment identified by vectoelectronystagmography (VENG). Methods: Descriptive and retrospective study, based on the analysis of medical records of 151 patients seen in the DSA of HRACUSP. The casuistry was delimited from the analysis of medical records of patients of both genders, aged between 10 and 88 years. Inclusion criteria were: vestibular complaints, VENG pre VR in group, response to Dizziness Handicap Inventory (DHI) and Visual Analogue Scale (VAS) for the symptoms of dizziness and tinnitus, in the pre- and post-intervention stages. The VR was composed of 13 sessions of approximately 60 minutes, following a specific protocol elaborated for VR in a group. The statistical treatment was composed by the Test T, McNemar, Friedmann, Chi- Square, Fisher, Binominal and Kolmogorov-Smirnov tests. Significance (p) value was adopted equal to or less than 0.05. Results: The results obtained were compared with the results obtained for each classification level (p=0,001). In the analysis of VAS, there was a difference between the discount of dizziness (variance value = 0,000 to 0,092), or discomfort related to tinnitus (p=0,001). There was a difference in the evaluation of vestibular evaluation through VENG before and after VR (p=0,003). There was no correlation between age (p=0,610) and VR efficacy, with correlation with gender (p=0,028). There was a difference between the VENG results between the previous phases of the group (p=0,001). In the correlation between the VAS and the variables, there was a correlation with the female gender (p=0,000), with all age groups, except for 10 to 20 years (p=0,125) from 21 to 90 years and with peripheral vestibular impairment (p=0,000). Conclusion: The group VR protocol applied to patients with vestibular complaints was effective for complaint of dizziness and tinnitus, regardless of age. The female had more benefits with an VR than the male sex. VR was effective for all types of vestibular compromise, including findings identified as normal.(AU)

ABSTRACT

Abstract Introduction Dizziness is one of the most common symptoms among the population, producing numerous consequences for individual's quality of life. There are some questionnaires that can trace the patient's profile and quality of life impairment from dizziness, including the Dizziness Handicap Inventory (DHI) and the Visual Vertigo Analogue Scale (VVAS). Objective This study aims to correlate the results of the DHI and VVAS in patients with vestibular dysfunction. Methods This is a retrospective study of medical records of patients treated in a medical school between 2006 and 2012. Results of the DHI and EVA were collected and subjected to statistical analysis using Pearson's correlation test with p < 0.001. The significance level adopted for the statistical tests was p 0.05. Results A total of 91 records were included in this study, 72 (79.1%) from female and 19 (20.9%) from male patients, aged 23 to 86 years, with a mean age of 52.5 years. The mean score on the DHI total was 43.9 and 5.2 points for the EVA. The result of Pearson's correlation test was 0.54. Conclusion Self-perceived dizziness measured with the Dizziness Handicap Inventory has a regular and positive correlation with the Visual Vertigo Analog Scale in patients with vestibular dysfunction. The clinical trial is registered under number UTN U1111- 1170-5065.

ABSTRACT

El síndrome de nistagmo vertical hacia abajo (NVA) es una forma común de nistagmo de fijación adquirido que se presenta con nistagmo persistente con fase rápida en dirección descendente, mareo, oscilopsia y alteraciones de la marcha. Se considera un trastorno vestíbulo-cerebelar debido a un defecto en las células de Purkinje en el flóculo del cerebelo. Las causas reportadas con mayor frecuencia son los trastornos degenerativos cerebelares e isquemia cerebelar, sin embargo, en un gran porcentaje de los pacientes la etiología permanece incierta (forma idiopática). El NVA se puede dar en un contexto más amplio de neuropatía somatosensorial y ataxia cerebelar en el síndrome CANVAS. Las medidas terapéuticas incluyen evitar la posición supina y prona al descansar, rehabilitación vestibular y tratamiento farmacológico con aminopiridinas, entre otros. En este artículo presentamos dos casos de NVA así como la revisión de la literatura.


Downbeat nystagmus syndrome (DBN) is a frequent form of acquired fixation nystagmus, it presents with persisting nistagmus with fast phases directed downward, dizziness, oscillopsia and gait disturbances. It is considered a vestibulocerebellar disorder due to a bilateral defect of the Purkinje cells in the cerebellar flocculus. Most reported causes are degenerative disorders of the cerebellum and cerebellar ischemia, nevertheless the etiology remains unknown in a large percentage of patients (idiopathic form). DBN may present in a broader context of somatosensory neuropathy and cerebellar ataxia as in CANVAS syndrome. Therapeutic measures includes avoiding the supine and prone position when resting, vestibular rehabilitation, and pharmacologic treatment with aminopyridines, among others. In this article we present two cases of DBN and review of literature.

ABSTRACT

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.


RESUMO INTRODUÇÃO: Estímulos visuais podem induzir a adaptação vestibular e recuperar o equilíbrio corporal. OBJETIVO: Verificar o efeito de estímulos visuais por imagens digitais na reabilitação do equilíbrio corporal de vestibulopatias periféricas. MÉTODO: Estudo clínico, randomizado, prospectivo. Quarenta pacientes com vestibulopatia periférica crônica e idade entre 23 e 63 anos foram submetidos à 12 sessões de reabilitação com estímulos visuais em DVD (grupo experimental) ou aos exercícios de Cawthorne-Cooksey (grupo controle). Dizziness Handicap Inventory (DHI), escala visual analógica de tontura e testes de equilíbrio estático de Romberg sensibilizado e de apoio unipodal foram aplicados antes e após a intervenção. RESULTADOS: Antes e após a intervenção, não houve diferença entre os grupos experimental e controle (p > 0,005) no DHI, escala visual analógica e testes de equilíbrio estático. Após a intervenção, o grupo experimental e o controle apresentaram valores menores (p < 0,05) do DHI e da escala visual analógica de tontura e valores maiores (p < 0,05) nos testes de equilíbrio estático em algumas condições avaliadas. CONCLUSÃO: A inclusão de estímulos visuais por imagens digitais na reabilitação do equilíbrio corporal é eficaz na redução da tontura, na melhora da qualidade de vida e do controle postural de vestibulopatias periféricas.

ABSTRACT

Introduction Benign Paroxysmal Positional Vertigo (BPPV) is one of themost common and treatable causes of peripheral vestibular vertigo in adults. Its incidence increases with age, eventually leading to disability and a decreased quality of life. Objective The research aims to assess short-term effects of Otolith Repositioning Maneuver (ORM) on dizziness symptoms, quality of life, and postural balance in elderly people with Benign Paroxysmal Positional Vertigo. Methods A quasi-experimental study, which evaluated 14 elderly people that underwent the Otolith Repositioning Maneuver and reevaluation after one week. The authors performed statistical analysis by descriptive analysis of central tendency and dispersion; for pre- and post-treatment conditions, the authors used the Wilcoxon test. Results All aspects of the Dizziness Handicap Inventory (physical, functional, emotional, and total scores) as well as the Visual Analogue Scale (VAS) decreased after therapy (p < 0.05 and p = 0.001, respectively). However, more than half of the elderly participants did not achieve negative Dix-Hallpike. Regarding static and dynamic balance, there were significant differences in some parameters of the modified Clinical Test of Sensory Interaction and Balance, Limits of Stability and gait assessment measured by the Dizziness Gait Index (p < 0.05). Conclusion Results reveal clinical and functional benefits in elderly people with Benign Paroxysmal Positional Vertigo submitted to Otolith Repositioning Maneuver. However, most of the participants did not overcome Benign Paroxysmal Positional Vertigo and not all aspects of postural balance improved. Therefore, a longer follow-up period and a multidisciplinary team are required to establish comprehensive care for elderly patients with dizziness complaints.
