Le corps du spectateur est au centre d’une antinomie récurrente dans les théories de l’art, l’œuvre doit d’abord émouvoir l’esprit et, dans la relation qu’elle établit avec son observateur, le corps n’est qu’un intermédiaire qui ne doit pas être trop sollicité. Cependant, certaines œuvres semblent remettre en cause cette relation et altérer le statut du spectateur en cherchant à surprendre l’esprit pour émouvoir le corps. Définir le cinéma comme paradigme d’un dispositif d’immersion fictionnel s’inscrivant dans une chronologie en dehors de toute spécificité historique, permet alors de considérer autrement la position de face à face entre l’œuvre projetée et son spectateur en les incluant dans la structure même du dispositif. L’œuvre projetée apparaît comme variable d’un système clos, lui-même laboratoire de l’exercice de la perception humaine dont les conditions sensationnelles expérimentales rejoignent les conditions réelles dans certains cas particuliers. L’étude de trois sensations distinctes isole certains cas spécifiques et conduit à l’établissement et à l’observation des différentes altérations que subit le statut du spectateur dont le corps est également partie prenante de la réception de l’œuvre.De l’analyse du vertige, défini comme sensation complexe, émerge la filiation du paradigme exploré ainsi que la possibilité de contourner cette dichotomie cartésienne. Les larmes et leur dualité, le rire et la tristesse, redéfinies comme symbole d’un complexe de sensations, attirent l’attention sur la possibilité d’une double appréhension d’une œuvre d’art, l’une psychologique, l’autre physiologique. Enfin le dégoût, une sensation simple, pose le cas limite dans lequel l’esprit du spectateur est piégé et où seul son corps lui permet d’appréhender ce monde qui le submerge. / The spectator’s body is at the centre of a recurring antinomy in the theories of Art, the work must first move the mind and, in its relation with its observer,the body which is a mere medium not to be too much appealed to.However,some works of Art seem to challenge this relation and alter the spectator’s status by trying to surprise the mind to move the body. Defining cinema as the paradigm of a fictional immersion device, inscribed in a chronology outside any historical specificity,makes it possible to consider differently the face to face position between the projected work and its spectator by including them within the structure of the same device. The projected work looks like the variable of a closed system which is itself a laboratory for the exercise of human perception whose experimental conditions come close to real-life conditions in some particular cases. The study of three distinct sensations isolates some specific cases and leads to establish and observe different alterations undergone by the spectator’s status whose body is also part and parcel of the reception of the work.From the analysis of vertigo,defined as a complex sensation , the relation of the explored paradigm rises as well as the ability to get round that cartesian dichotomy.Tears and their duality,laughter and sadness,redefined as a symbol of complex sensations draw attention to a potential double apprehension of a work of Art, both psychologically physiologically.Lastly, disgust, a simple sensation,sets a borderline case in which the spectator’s mind is trapped and where only his body enables him to grasp the world he is submerged in.

Múltiples revisiones científicas han intentado determinar los factores pronósticos en la evolución del latigazo cervical sin llegar a un consenso. Nuestros resultados se han obtenido tras 8 años de estudio en pacientes controlados desde la primera visita en el servicio de Medicina Física y Rehabilitación del Hospital de Mataró. Se han utilizado escalas de valoración fáciles de cumplimentar y cuantificar para poder obtener los resultados en el mismo momento de la consulta. Este hecho es importante, ya que la mayoría de las escalas que se identifican en los artículos publicados son poco prácticas en la consulta diaria por la dificultad que conllevan en su cumplimentación y valoración. Los factores pronósticos que hemos identificado en nuestra muestran han sido: la edad, la presencia de “vértigos”, la intensidad del dolor cervical inicial valorada mediante la escala analógica visual y el grado de funcionalidad cervical inicial valorado mediante el Northwick Park Hospital Neck Pain Questionnaire.

INTRODUÇÃO: Os Potenciais Evocados Auditivos avaliam a atividade neuroelétrica da via auditiva desde o nervo auditivo até o córtex cerebral. A vectoeletronistagmografia permite analisar os canais semicirculares e/ou nervo vestibular inferior, verificando se existe comprometimento vestibular periférico ou central. A reabilitação vestibular é composta de exercícios físicos ativos e repetitivos de olhos, cabeça e corpo e/ou manobras específicas que visam diminuir a tontura e a instabilidade corporal, aumentar a estabilização no olhar, o controle postural e melhorar o bem-estar na realização das atividades do diaa- dia. Levando-se em conta a escassez de trabalhos na literatura que investiguem a via auditiva central em indivíduos com síndrome vestibular periférica e que sejam submetidos à reabilitação vestibular, torna-se importante conhecer o funcionamento do sistema auditivo central, desde o tronco encefálico até o córtex auditivo, em indivíduos com vestibulopatias periféricas. OBJETIVOS: caracterizar os potenciais evocados auditivos de curta, média e longa latências em indivíduos com vestibulopatias periféricas, bem como verificar a evolução destes potenciais e dos resultados obtidos no Dizziness Handicap Inventory (DHI) frente à reabilitação vestibular. MÉTODOS: Foram submetidos à avaliação eletrofisiológica da audição por meio dos potenciais evocados auditivos de tronco encefálico (PEATE), potencial evocado auditivo de média latência (PEAML) e potencial cognitivo (P300), bem como à aplicação do questionário DHI, antes e após reabilitação vestibular, 20 indivíduos com diagnóstico de Síndrome Vestibular Periférica Irritativa (SVPI) e 17 indivíduos com diagnóstico de Síndrome Vestibular Periférica Deficitária (SVPD), com idades entre 20 e 70 anos. RESULTADOS: Os resultados demonstraram que o grupo com SVPD apresentou maior porcentagem de resultados alterados no PEATE e PEAML. No que diz respeito aos tipos de alterações, pode-se observar no grupo com SVPD, alteração em tronco encefálico baixo no PEATE pré e pós RV; aumento das latências das ondas Na e Pa no PEAML pós RV, aumento da latência da onda Pa pré RV e efeito eletrodo para a amplitude Na- Pa pós RV. No grupo com SVPI, foi observada alteração do tipo outros no PEATE pré RV; aumento da latência da onda Pa no PEAML pré e pós RV e ambas as alterações para a amplitude Na-Pa pós RV. No estudo da evolução dos resultados pré e pós RV, pode-se observar maior porcentagem de resultados semelhantes para os três potenciais, em ambos os grupos avaliados. Na comparação do DHI pré e pós RV, ocorreram melhores resultados para os aspectos físico, emocional e funcional no grupo com SVPI e para os aspectos físico e emocional no grupo com SVPD. Tornam-se necessários mais estudos que avaliem a via auditiva central destes indivíduos para uma melhor caracterização dos achados eletrofisiológicos / INTRODUCTION: The auditory evoked potentials assess the neuroelectrical activity of the auditory pathway from the auditory nerve to the cerebral cortex. The vectoelectronystagmography analyzes the semicircular canals and/or inferior vestibular nerve, checking peripheral or central vestibular involvement. The vestibular rehabilitation therapy consists in active exercises and repetitive eyes exercises, head and body and/or specific maneuvers to reduce the dizziness and body instability, increase gaze stability and postural control and also improve well-being in daily activities. Taking into account the scarcity of studies in the literature that investigate the central auditory pathways in subjects who underwent vestibular rehabilitation therapy, it becames important to know the central auditory system from the brainstem to the auditory cortex, in subjects with peripheral vestibular disorders. OBJECTIVE: To characterize the auditory evoked potentials of short, middle and long latencies in subjects with peripheral vestibular disorders, as well as to evaluate the development of these potentials and the results obtained in the Dizziness Handicap Inventory (DHI) after vestibular rehabilitation therapy (VRT). METHODS: brainstem auditory evoked potential (BAEP), Auditory Middle- Latency Response (AMLR), cognitive potential (P300) and DHI were carried out in 20 subjects with Peripheral Vestibular Hyperfunction Syndrome and 17 subjects with Peripheral Vestibular Hypofunction Syndrome, aged between 20 and 70, before and after vestibular rehabilitation therapy. RESULTS: The results showed that the Peripheral Vestibular Hypofunction Syndrome group, presented higher percentage of altered results on BAEP and AMLR. Comparing the normal and altered results (qualitative analysis) between the groups in the BAEP, lower brainstem was predominantly observed in the Peripheral Vestibular Hypofunction Syndrome group before and after VRT; increased latencies of Na and Pa waves in AMLR after VRT, incresead latency of Pa wave in AMLR before VRT and electrode effect to the Na-Pa amplitude after VRT. The alteration predominantly observed in the Peripheral Vestibular Hyperfunction Syndrome group, was the other type one before VRT; increased latency of Pa wave in AMLR before and after VRT and both changes to the Na-Pa amplitude after VRT. In the study of the evolution before and after VRT, it was observed a higher percentage of similar results for the three potentials in both groups. Comparing results before and after VRT, the DHI greatest improvement occurred for the physical, emotional and functional aspects in the Peripheral Vestibular Hyperfunction Syndrome group and for the physical and emotional aspects in the Peripheral Vestibular Hypofunction Syndrome group. Further studies that evaluate the central auditory pathway of individuals with peripheral vestibular syndrome are needed to better characterize the electrophysiological findings

In the first article submitted to "Journal of Otolaryngology" with the title benign paroxysmal positional vertigo without nystagmus: diagnosis and treatment, there was a literature review, using the following keywords: "dizziness / vertigo, diagnosis / diagnosis, therapeutic / therapeutical approaches. " Scientific publications are included in the period 2001-2009 in Portuguese, English and German. We found nine papers dealt with BPPV without nystagmus, whose diagnosis was based exclusively on clinical history and physical examination. The treatment of BPPV without nystagmus was made by Epley maneuvers, Semont, discharge modified for posterior semicircular canal and Brandt-Daroff exercises. All show that 50% to 97.1% of patients with BPPV without nystagmus, had remission of symptoms, while patients with BPPV nystagmus with remission of symptoms ranged from 76% to 100%. Hence one can conclude that the differences may not be significant, which demonstrates the need for further studies on BPPV without nystagmus. In the second paper, Functional Capacity of Elderly with benign paroxysmal positional vertigo, compared the functional capacity among elderly patients with BPPV and elderly without clinical diagnosis of BPPV and that / or dizziness or vertigo, identifying the physical activities of daily living and instrumental activities of daily living in elderly people in both the Group of Elderly with BPPV (EBPPVG) and Control Group (CG). This is a cross-sectional study, case-control study in Hospital Geral de Goiânia (HGG), with the participation of 14 elderly patients with a diagnosis of BPPV and the Programa de Gerontologia Social / Universidade Aberta à Terceira Idade (UNATI) from the Pontificia Universidade Católica de Goiás (PUC-GO), with the participation of 13 subjects without dizziness or vertigo and / or clinical diagnosis was of BPPV. Functional capacity was assessed by the subscale of the Functional Assessment Questionnaire Brazilian Multidimensional Functional Capacity / Operating Older American Resources and Services Multidimensional Functional Assessment Questionnaire (BOMFAQ/OARS), verifying that the difficulty in performing 15 activities of daily living (ADL), eight physical activities of daily living (AFVD): throw / out of bed, eating, combing hair, walk on the plane, bathing, dressing, going to the bathroom in time and trimming toenails, and seven instrumental activities of living daily living (IADL): climbing stairs (one flight), doctor-on time, walk close to home, shopping, preparing meals, driving out and do house cleaning. Arrived at the following conclusions: a) elderly people with BPPV showed a statistically significant lower functional capacity than subjects without this diagnosis, b) in EBPPVG, the average number of daily activities (physical and instrumental), those with difficulty was 6.53 with a maximum of 11 activities committed while in the CG, the average impairment was 0.86 with a maximum of 4 activities referred with difficulty in performing c) EBPPVG affected performance in 13 activities of daily living, including physical seventh floor in the plan, bathing, dressing, combing hair, going to the bathroom in time, bedtime and getting up from bed or chair and cut nails feet, and 6 which are instrumental, climbing stairs, walking around the house, shopping, preparing meals, driving out and do house cleaning in the comparison between groups, d) Activities that were cited as the most difficult among the elderly were similar in both groups. However, the degree of impairment, characterized in: without commitment (when the elderly did not report any difficulty in any of the 15 evaluated ADL), mild (1 to 3 activities impaired), moderate (4-6 impaired activities) and severe (for seven or more impaired activities) was significantly higher in EBPPVG, where 7 (50%) showed severe impairment in ADL performance. / Dissertação construída na modalidade artigo científico. No primeiro artigo enviado para a Revista Brasileira de Otorrinolaringologia com o título Vertigem Posicional Paroxística Benigna sem nistagmo: diagnóstico e tratamento, realizou-se uma revisão da literatura, utilizando-se os seguintes descritores: vertigem/vertigo, diagnóstico/diagnosis, conduta terapêutica/ therapeutical approaches , palavras e assunto vertigem , nistagmo , VPPB , VPPB sem nitagmo , VPPB subjetiva . As publicações científicas incluídas são do período de 2001 a 2009 nos idiomas português, inglês, espanhol e alemão. Foram encontrados nove artigos que abordam a VPPB sem nistagmo, cujo diagnóstico foi baseado exclusivamente na história clínica e no exame físico. O tratamento da VPPB sem nistagmo foi realizado pelas manobras de Epley, Sémont, liberatória modificada para canal semicircular posterior e exercícios de Brandt-Daroff. Todos evidenciam que de 50% a 97.1% dos pacientes com VPPB sem nistagmo, tiveram remissão dos sintomas, enquanto nos pacientes com VPPB com nistagmo a remissão dos sintomas variou de 76% a 100%. Conclui-se que as diferenças podem não ser significativas, o que demonstra a necessidade de mais estudos sobre a VPPB sem nistagmo. No segundo artigo, com o título Capacidade Funcional de Idosos com Vertigem Posicional Paroxística Benigna, comparou-se a capacidade funcional entre idosos com VPPB e idosos sem diagnóstico clínico referido de VPPB e/ou queixa de tontura ou vertigem, identificando as atividades físicas de vida diária e as atividades instrumentais de vida diária comprometidas nos idosos tanto no Grupo de Idosos com VPPB (GIVPPB) quanto no Grupo Controle (GC). Trata-se de um estudo transversal, analítico, observacional e comparativo, realizado no Hospital Geral de Goiânia (HGG), com a participação de 12 idosos com diagnóstico de VPPB e no Programa de Gerontologia Social/ Universidade Aberta á Terceira Idade (UNATI) da Pontifícia Universidade Católica de Goiás (PUC-GO), com a participação de 13 idosos sem queixa de tontura ou vertigem e/ou diagnóstico clínico referido de VPPB. A capacidade funcional foi avaliada por meio da subescala funcional do Questionário Brasileiro da Avaliação Multidimensional de Capacidade Funcional/Brazilian Older American Resources and Services Multidimensional Functional Assessment Questionaire (BOMFAQ/OARS), verificando a dificuldade referida na realização de 15 atividades de vida diária (AVD), sendo oito atividades físicas de vida diária (AFVD): deitar/levantar da cama, comer, pentear cabelo, andar no plano, tomar banho, vestir-se, ir ao banheiro em tempo e cortar unhas dos pés, e sete atividades instrumentais de vida diária (AIVD): subir escada (um lance), medicar-se na hora, andar perto de casa, fazer compras, preparar refeições, sair de condução e fazer limpeza de casa. Chegou-se às seguintes conclusões: a) idosos com VPPB apresentam uma capacidade funcional estatisticamente significativa menor do que idosos sem este diagnóstico; b) no GIVPPB, o número médio de atividades de vida diária (físicas e instrumentais), referidas com dificuldade foi de 6,53 com o máximo de 11 atividades comprometidas, enquanto no GC, a média de comprometimento foi de 0,86 com o máximo de 4 atividades referidas com dificuldade no desempenho; c) A VPPB prejudicou o desempenho em 13 atividades de vida diária, 7 físicas incluindo andar no plano, tomar banho, vestir-se, pentear-se, ir ao banheiro em tempo, deitar e levantar-se da cama ou cadeira e cortar unhas dos pés; e 6 instrumentais quais sejam, subir escada, andar perto de casa, fazer compras, preparar refeições, sair de condução e fazer limpeza da casa na comparação entre os grupos; d) As atividades que foram referidas como mais difíceis entre os idosos, foram similares em ambos os grupos. Contudo, o grau de comprometimento, caracterizado em: sem comprometimento (quando o idoso não referia dificuldade em nenhuma das 15 AVD avaliadas), leve (de 1 a 3 atividades comprometidas), moderado (de 4 a 6 atividades comprometidas) e severo (de sete ou mais atividades comprometidas) foi significativamente maior no GIVPPB, onde 7(50%) evidenciaram severo comprometimento no desempenho das AVD.

The first article is a systematic review that aimed to investigate the relationship between BPPV and falls (with and without fracture). The review was carried out independently by two researchers, using the combined descriptors in English, Portuguese and Spanish, "vertigo" and "elderly" and "accidental falls"; "benign paroxysmal positional vertigo" and "accidental falls"; in the Virtual Health Library and United States National Library of Medicine (PubMED) databases, being the last search in August 2016. Six scientific papers were selected. The results showed that there were double falls in the elderly with the diagnosis of BPPV and this the relationship increased with advancing age. There was evidence of a decrease in episodes of falls above 60% of the elderly who were treated for BPPV. In elderly people with more than one cause for dizziness, BPPV can not be considered as an independent risk factor for falls. However, in the hospital environment, the relationship between BPPV and falls was not observed when the investigation was performed from the hip fracture. However, when the study included elderly patients hospitalized for various consequences of falls, BPPV could be identified in more than 50% of the patients. It can be concluded that BPPV is associated with falls. The second article, whose primary objective was to evaluate dizziness in the elderly in the primary care for the recognition of BPPV and the secondary one, to analyze the association between dizziness and BPPV with falls. It was a cross-sectional study of 298 diabetic and / or hypertensive elderly individuals enrolled in the Hypertensive and Diabetic Monitoring System of the Basic Family Health Unit of the Madre Germana II neighborhood of Goiânia, Goiás. The evaluation was carried out at the residence of the elderly, including the Mini Mental State Examination, sociodemographic profile, record of self-reported health conditions with emphasis on reporting dizziness and / or vertigo and record of falls in the last 12 months. The elderly who reported dizziness and/or vertigo were revisited for functional otoneurological evaluation for BPPV, using the Dix Hallpike test for the posterior and anterior semicircular canals and the Supine Roll test for the horizontal semicircular canal. The study included 150 elderly individuals with a mean age of 69.7 (+/- 7.36), the majority of them were female. Dizziness was reported by 50 elderly (33.3%). Among the 50 patients who reported dizziness, 19 had objective and subjective BPPV (38.8%). There was association between the complaint of dizziness and falls (p = 0.05), which did not occur with BPPV. The assessment of dizziness and BPPV can be performed in the home of the elderly in primary care. This proactive approach can help prevent falls because dizziness has increased the chances of the elderly falling. Although elderly people who presented objective or subjective BPPV did not increase their chances of falls, the identification of this disease, which has a known, effective and financially inexpensive treatment, may lead to the resolution of this clinical condition. / Tese construída na forma de artigos científicos. O primeiro artigo é uma revisão sistemática que objetivou investigar a relação entre VPPB e quedas (com e sem fratura). A revisão foi realizada de forma independente por duas pesquisadoras, utilizando os descritores combinados em inglês, português e espanhol, “vertigem” and “idoso” and “acidentes por quedas"; “vertigem posicional paroxística benigna” and idoso and acidentes por quedas”; vertigem posicional paroxística benigna” and “acidentes por quedas”, nas bases de dados Biblioteca Virtual em Saúde (BVS), United States National Library of Medicine (PubMED), sendo a última busca em agosto de 2016. Foram selecionados seis artigos. Observou-se diversidade metodológica entre os estudos. Quedas ocorreram o dobro de vezes em idosos com o diagnóstico de VPPB e esta relação aumentou com o avanço da idade. Houve evidência de diminuição de episódios de quedas acima de 60% dos idosos que foram tratados da VPPB. Em idosos com mais de uma causa para a tontura, a VPPB não pode ser considerada como fator de risco independente para quedas. Contudo, no ambiente hospitalar, a relação entre VPPB e quedas não foi observada quando a investigação foi realizada a partir da fratura de quadril. No entanto, quando o estudo incluiu idosos internados por consequências diversas de quedas, a VPPB pôde ser identificada em mais de 50% dos pacientes. Pode-se concluir que a VPPB está associada a quedas. O segundo artigo, teve como objetivos, avaliar a tontura em idosos na atenção primária para o reconhecimento da VPPB e analisar a associação entre tontura e VPPB com quedas. Foi um estudo do tipo transversal sendo estudados 298 idosos diabéticos e/ou hipertensos, cadastrados no Sistema de Acompanhamento de Hipertensos e Diabéticos da Unidade Básica de Saúde da Família do bairro Madre Germana II de Goiânia, Goiás. A avaliação foi realizada na residência dos idosos incluindo o Mini Exame do Estado Mental, perfil sociodemográfico, registro das condições de saúde auto referidas com ênfase no relato de tontura e/ou vertigem e registro de quedas nos últimos 12 meses. Os idosos que referiram tontura e/ou vertigem foram revisitados para avaliação funcional Abstract xvi otoneurológica para VPPB, utilizando o teste de Dix Hallpike para os canais semicirculares posterior e anterior e Supine Roll test para o canal semicircular horizontal. Foram incluídos no estudo 150 idosos com média de idade de 69,7(+/-7,36), a maioria do sexo feminino e 26% referiam queda. Tontura foi referida por 33% dos idosos, dentre os quais, 38,8% apresentaram VPPB. Houve associação entre a queixa de tontura e quedas (p=0,05), o que não ocorreu com a VPPB objetiva ou subjetiva. A avaliação da tontura e VPPB pode ser realizada no domicílio de idosos na atenção primária.

Dizziness is a common, multifactorial problem that causes reductions in quality of life and is a major risk factor for falls, but the role of vision is a very under-researched area. This study aimed to investigate any link between dizziness and vision and to establish if changes in spectacle lens correction could elicit dizziness symptoms. A link between dizziness and self-reported poor vision was indicated in the epidemiological literature as shown by a systematic review, provided lightheadedness was not included in the definition of dizziness. Cases of individuals who reported vision-related dizziness were investigated to determine potential areas of research for this thesis and subsequently two studies investigated the effects of refractive correction changes on dizziness status. The first study was limited by logistical problems, although it highlighted limitations in the short form of the Dizziness Handicap Inventory that was used to quantify dizziness. Results of an optometry practice recheck study found that oblique cylindrical changes were significantly more likely to be associated with dizziness symptoms than other spectacle lens changes. It also highlighted that optometrists do not ask/record about dizziness symptoms with only 4% of records including “dizziness” as a problem when 38% of patients reported dizziness symptoms when directly asked. All studies highlighted a need for a patient-reported outcome measure to be designed to assess vision-related dizziness. Literature review, interviews with experts and patients and focus groups led to the development of a pilot questionnaire and subsequently a 25-item Vision-Related Dizziness instrument, the VRD-25. This was validated using responses from 223 respondents, with 79 participants completing the questionnaire a second time to provide test-retest data. Two subscales of VRD-12-frequency (VRD-12f) and VRD-13-severity (VRD-13s) were shown to be unidimensional and had good psychometric properties, convergent validity and test-retest repeatability. The VRD-25 is the only patient-reported outcome measure developed to date to assess vision related dizziness and will hopefully provide the platform to further grow this under-researched area that seems likely to provide important clinical information. / College of Optometrists sponsored the research with a Postgraduate Research Scholarship

Dizziness is very common, but it is never normal. Dizziness can make performing daily activities, work, and walking difficult. Inner ear balance problems can make people dizzy when they turn their head, which can cause problems during walking and make people more likely to fall. Most of the time dizziness is not from a life-threatening disease. Often, dizziness is related to a problem of the vestibular (or inner ear balance) system. Vestibular disorders can be caused by infections in the ear, problems with the immune system, medications that harm the inner ear, and rarely from diabetes or stroke because of a lack of blood flow to the inner ear. Stress, poor sleep, migraine headaches, overdoing some activities, and feeling anxious or sad can increase symptoms of dizziness. Updated guidelines for the treatment of inner ear disorders are published in this issue of the Journal of Neurologic Physical Therapy. The guideline recommends which exercises are best to treat the dizziness and balance problems commonly seen with an inner ear problem.
