Using EEG in neurofeedbacktraining to decrease visual motionsensitivity and motion-sickness / Träning med EEG neurofeedback i syfte att minska känsligheten för visuell rörelse och åksjuka

Rúnarsson, Ódinn K. January 2021 (has links)
Patients who suffer from motion-sickness, visual vertigo and other conditions relating to visual hypersensitivity will often feel dizzy when exposed to rapid visual motion or cluttered fields-of-view. Previous studies indicate that attentiveness to these stimuli influence the intensity of discomfort for these individuals, which suggests that mentally ignoring visual stimuli might help make them more tolerable. This thesis project had two goals. The primary goal was the development of a visual biofeedback system for use with a commercial electroencephalographic headset and a personal computer. The secondary goal was to evaluate its usefulness for treating motion-sickness and other related illnesses through regular training sessions. A neurofeedback program was constructed using MATLAB and a Muse 2 Brain Sensing Headband (Muse). The program projected a spinning maze like pattern on a monitor where increase in velocity was proportional to increase in theta wave activity (3.5-6.5 Hz) detected by the Muse. Five test subjects (three men and two women) were given a copy of the program and a Muse, and then instructed to practice reducing their EEG activity (e.g. by calming themselves), which would be reflected in the program as a slower spin velocity of the maze. These practice sessions took place daily for seven days. Neurofeedback proficiency and body sway data was collected before and after. Mean spectral power data from the training regimen shows a 23.7% drop in theta wave activity from first session to last (p = 0.005). Using Pearson’s correlation, no significant results were obtained while comparing training improvements and proficiency test improvements (r = -0.22, p = 0.72) or reduction in body sway (r = 0.78, p = 0.12).

Schwindel in der Allgemeinarztpraxis: Prävalenz, Versorgungsqualität und seine Assoziation mit Ängstlichkeit und Depressivität

Sandel, Richard 30 July 2014 (has links) (PDF)
Hintergrund: Schwindel ist ein häufig vorgetragenes Symptom beim Hausarzt. Seine erhöhte Vergesellschaftung mit Ängstlichkeit und Depressivität ist aber bisher zu wenig untersucht worden, ebenso wenig ist dieser Zusammenhang Gegenstand der hausärztlichen Behandlung von Schwindelpatienten. Zielstellung: Kommen unbekannte psychische Hintergründe in Kombination mit Schwindel im hausärztlichen Patientengut häufiger vor als ohne Schwindel? Ergeben sich daraus als Konsequenz unterschiedliche Versorgungsformen durch den Hausarzt? Wie verhält es sich mit deren subjektiven Gesundheitszustand, dem Erfolg der hausärztlichen Behandlung, dem ihnen entgegengebrachten Verständnis und der Häufigkeit der Arztbesuche der Betroffenen? Studiendesign: Prospektive Multicenterstudie in der Allgemeinpraxis Untersuchungsregion: Zehn Hausarztpraxen in Halle a.d. Saale und Nordsachsen/ Leipzig im städtischen und ländlichen Einzugsbereich, welche von Fachärzten für Allgemeinmedizin geführt wurden. Methodik: Die Studie untersuchte insgesamt 590 zufällig am Untersuchungstag eintreffende Patienten in jeweils einer von insgesamt zehn Hausarztpraxen. Die Ausprägung von Schwindelbeschwerden und eventuell vorhandene Merkmale von Ängstlichkeit und Depressivität beim jeweiligen Patienten wurden mit Elementen des Gießener Beschwerdebogens 24 und der Hospital Anxiety and Depression Scale (deutsche Version) untersucht. Ergebnisse: Die Patienten wurden in eine Gruppe mit relevanten (29,7%, n=175) und in eine Gruppe ohne relevante Schwindelbeschwerden (70,3%, n=408) eingeteilt (Cut off >=8 nach GBB 24). Die Gruppe mit relevantem Schwindel wies häufiger Merkmale für Ängstlichkeit (p<0,001) und Depressivität (p<0,001) in allen Altersgruppen auf, zeigte sich unzufriedener mit ihrem Behandlungserfolg (p=0,004), schätzte ihren aktuellen Gesundheitszustand schlechter ein (p<0,001) und konsultierte ihren Hausarzt in den letzten zwölf Monaten häufiger (p=0,020). Sie stellten sich nach ICPC-2 häufiger wegen neurologischer (p<0,001), psychologischer (p=0,026) und unspezifischer Beschwerden (p<0,001) vor. Sie erhielten mehr Diagnosen aus den ICD-10-Kapitel V (Psychische und Verhaltensstörungen) (p=0,030). Diese Patienten waren nach HADS-D auch häufiger psychisch auffällig (p<0,001). Relevanter Schwindel kam bei Frauen aller Altersgruppen häufiger vor als bei Männern (p<0,001). Dennoch ergaben sich keine Behandlungsunterschiede durch die Hausärzte zwischen beiden Gruppen (p=0,101 bis 0,930 je nach ärztlicher Maßnahme). Schlussfolgerung: Schwindelpatienten weisen häufger Ängstlichkeit und Depressivität auf, welche den Schwindel unterhalten. Dieser Zusammenhang sollte in der Sprechstunde bedacht werden. Die psychischen Hintergründe sollten vom Hausarzt aufgedeckt und behandelt werden. Dadurch könnte der Schwindel und damit der subjektive Gesundheitszustand der betroffenen Patienten verbessert und die Inanspruchnahme des Gesundheitswesens verringert werden.

Growing up with Vertigo: British Writers, DC, and the Maturation of American Comic Books

Salisbury, Derek 19 September 2013 (has links)
At just under thirty years the serious academic study of American comic books is relatively young. Over the course of three decades most historians familiar with the medium have recognized that American comics, since becoming a mass-cultural product in 1939, have matured beyond their humble beginnings as a monthly publication for children. However, historians are not yet in agreement as to when the medium became mature. This thesis proposes that the medium’s maturity was cemented between 1985 and 2000, a much later point in time than existing texts postulate. The project involves the analysis of how an American mass medium, in this case the comic book, matured in the last two decades of the twentieth century. The goal is to show the interconnected relationships and factors that facilitated the maturation of the American sequential art, specifically a focus on a group of British writers working at DC Comics and Vertigo, an alternative imprint under the financial control of DC. The project consulted the major works of British comic scriptwriters, Alan Moore, Jamie Delano, Grant Morrison, Peter Milligan, Neil Gaiman, Warren Ellis, and Garth Ennis. These works include Watchmen, V for Vendetta, Shade: the Changing Man, Batman: Arkham Asylum, Animal Man, Sandman, Transmetropolitan, Preacher and several other important works. Following a chronological organization, the work tracks major changes taking place in the American comic book industry in the commercial, corporate, and creative sectors to show the processes through which the medium matured in this time period. This is accomplished by combining textual analysis of the comics with industry specific records and a focus on major cultural shifts in US society and culture

Ressonância funcional na tontura postural-perceptual persistente / Functional resonance in persistent postural-perceptual dizzness

Lins, Eliane Maria Dias Von Sohsten 22 September 2015 (has links)
Objetivo: avaliar as diferenças estruturais e funcionais entre o cérebro de pacientes com tontura postural-perceptual persistente (TPPP) e controles. Método: o estudo foi aprovado pela comissão de ética local. As voluntárias deram consentimento formal. 16 mulheres com TPPP (44.7±8.3 anos) e 16 controles (46.5±8.5 anos) foram pareadas por sexo e idade. Imagens de ressonância magnética funcional (RMf) e estrutural foram adquiridas utilizando sistema 3.0 T durante a visibilização de figuras padronizadas do International Affective Pictures System (IAPS) com valência negativa, positiva e neutra. Realizou-se análise estrutural segmentar e volumétrica com o programa Freesurfer e funcional com o FSL (FMRIB Software Library) usando correção fatia-tempo e de movimento, suavização espacial (5mm FWHM), e normalização no espaço standard MNI (Montreal Neurological Institute). O modelo linear geral (GLM) incluiu regressores por grupo e condições. Adotou-se um limiar de Z = 3.09 (p < 0.001) para cada vóxel, e um nível de significância para correção de clusters de p < 0.05. O Z=2.3 foi utilizado na comparação entre grupos. Resultados: o grupo com TPPP apresentou ativação na região do córtex cingulado anterior na diferença entre contrastes positivos e negativos por queda de sinal na visibilização de estímulos negativos; enquanto o grupo controle teve efeito BOLD (Blood Oxygen Level Dependent) positivo na região amigdaliana bilateralmente na diferença entre contrastes negativos e positivos. Houve ativação em giro angular esquerdo na diferença entre contrastes negativos e positivos e entre grupos (pacientes > controles). Conclusão: ativação em região amigdaliana em resposta a estímulos negativos em relação aos positivos é frequentemente encontrada em pacientes com ansiedade e síndrome do estresse pós-traumático, mas não foi vista no nosso grupo com TPPP, só no controle. Por outro lado, o grupo com TPPP mostrou desativação da região do córtex cingulado anterior, um modelo descrito em algumas, mas não em todas as disfunções ansiosas, e não identificado no grupo controle. Além disto, o efeito BOLD positivo na região do giro angular esquerdo, área não inclusa no sistema límbico, com múltiplas funções, dentre elas a orientação espacial, indicam que mais trabalhos são necessários para elucidar o mecanismo cerebral da TPPP / Objectives: evaluate structural and functional differences in brain among patients with postural perceptual persistent dizziness (PPPD) and controls. Method: The study was approved by local IRB, and volunteers gave their informed consent. Sixteen women with PPPD (44.7 ± 8.3 years-old) were compared to 16 controls (46.5 ± 8.5 years-old) matched by age and gender. Structural and functional brain images were acquired in a 3.0T MRI system while subjects were presented with pictures from a standard reference (International Affective Pictures System - IAPS) with positive, neutral and negative emotional valence stimuli. Structural images were analysed in Freesurfer program and fMRI images in FSL (FMRIB Software Library) using slice-time and motion correction, spatial smoothing (5mm FWHM), and normalized images into MNI standard space. The GLM model included regressors for groups and conditions. A threshold Z-score = 3.09 (p < 0.001) was used for each voxel, and was adopted the correction by clusters at a p < 0.05 significance level. A Z-score = 2.3 was used for comparison between groups. Results: the PPPD group showed increased brain response at anterior cingulate cortex when comparing [positive > negative] stimuli as a result of deactivation during negative stimuli, whereas the control group had positive BOLD when comparing [negative > positive] stimuli at amigdala region in both sides. PPPD group had increased brain response when comparing [negative>positive] stimuli and [patients > controls] in the left angular gyrus. Conclusion: The amygdala region activation in control group in response to negative than positive stimuli is a pattern often found in patients with anxiety and traumatic stress but not was seen in our patient group. In contrast, they showed deactivation of the anterior cingulate cortex in response to negative stimuli, a pattern found in some, but not all anxiety disorders, and not identified in the control group. Otherwise, the positive BOLD in angular gyrus, brain area not included in limbic system, with multiple functions, including spatial orientation, indicate that more work is needed to elucidate brain mechanisms underlying PPPD

Eficácia dos exercícios de adaptação do reflexo vestíbulo-ocular no tratamento da vertigem aguda / Efficacy of vestibulo-ocular reflex exercises in the treatment of acute vertigo

Venosa, Alessandra Ramos 03 August 2005 (has links)
Introdução: Desde sua primeira descrição na década de 40 o espectro de aplicação da reabilitação vestibular vem crescendo, tornando-se opção de tratamento em disfunções vestibulares periféricas, incluindo as uni e bilaterais, e em doenças do sistema nervoso central. O presente estudo avalia a eficácia de exercícios que estimulam a adaptação do reflexo vestíbulo-ocular em indivíduos com quadro agudo de vertigem. Métodos: neste estudo clínico prospectivo foram avaliados indivíduos aleatoriamente alocados em um grupo de estudo, que realizou exercícios para adaptação do reflexo vestíbulo-ocular, e em um grupo controle, que realizou exercícios placebo. Os critérios de inclusão foram história de pelo menos um episódio de vertigem nos últimos cinco dias, idade acima de 18 anos, e alteração em pelo menos dois dos testes objetivos de equilíbrio (teste de Romberg, teste de Fukuda e \"head-shaking\" nistagmo) e/ou presença de nistagmo espontâneo. Os pacientes de ambos os grupos foram orientados a utilizar dimenidrato na dose máxima de 150 mg ao dia, divididas em três doses, podendo auto-regular a dose conforme a intensidade dos sintomas apresentados. Foram excluídos indivíduos que tivessem utilizado medicação com ação no sistema vestibular nos últimos sete dias, com presença de alterações sugestivas de doença do sistema nervoso central, diagnóstico de vertigem posicional paroxística benigna ou de fístula perilinfática. Os pacientes foram avaliados, no início do estudo e em três visitas subseqüentes, realizadas nos períodos de três a cinco dias, sete a dez dias e dezoito a vinte e um dias após o início da pesquisa. Em todas as visitas a avaliação foi realizada por meio de notas atribuídas à intensidade dos sintomas (escala analógica visual), quantidade de medicação utilizada e resultados dos testes de equilíbrio. Resultados: Foram analisados 87 xxxv indivíduos, 45 no grupo de estudo e 42 no grupo controle. Na avaliação inicial os grupos eram semelhantes do ponto de vista estatístico em relação ao sexo e idade dos pacientes, tempo decorrido entre o início dos sintomas e a primeira avaliação, intensidade dos sintomas e achados de exame físico. O grupo de estudos apresentou intensidade de sintomas inferior ao grupo controle nas segunda e terceira avaliações; na quarta e última avaliação ambos os grupos apresentaram sintomatologia semelhante. A quantidade de medicação utilizada pelos pacientes do grupo de estudos foi inferior à utilizada pelo grupo controle em todos as avaliações realizadas. Não houve diferença entre os grupos em relação ao desaparecimento do nistagmo espontâneo exceto na terceira avaliação. A proporção de pacientes com teste de Romberg alterado foi menor no grupo de estudo quando comparada ao grupo controle nas segunda (tendência à significância estatística) e terceira avaliações, não havendo diferença entre os grupos na última avaliação. Nos testes de Fukuda e de \"head-shaking\" nistagmo não houve diferença entre os grupos em relação à proporção de testes alterados nas primeira e segunda avaliações, entretanto nas terceira e quarta avaliações o grupo de estudos teve menor proporção de testes alterados. Conclusões: O grupo submetido aos exercícios para adaptação do reflexo vestíbulo-ocular obteve melhora clínica mais rápida, fez uso de quantidade menor de dimenidrato e apresentou normalização dos testes clínicos de equilíbrio mais precocemente quando comparado ao grupo controle / Introduction: Since its first description in 1940 decade, the spectrum of use of vestibular rehabilitation has broadened and nowadays comprises unilateral, bilateral and even central vestibular disorders. The objective of this study is to evaluate the effect of exercises for adaptation of the vestibuloocular reflex in patients with acute vertigo. METHODS: Study design: prospective randomized trial, patients blinded to assignment groups. The study population had the following characteristics: = 18 years of age, at least one episode of vertigo in the last five days, negative results in at least two objective vestibular tests and/or presence of spontaneous nystagmus. The exclusion criteria were: use of any medication interfering with the vestibular system in the past seven days, clinical history or physical findings indicative of central nervous system disorders, clinical diagnosis of benign paroxysmal positional vertigo or perilymphatic fistula. Patients were randomly allocated to the intervention and placebo controlled groups. Intervention group performed exercises for adaptation of the vestibulo-ocular reflex; control group performed placebo exercises. Both groups were instructed to use dimenhydrinate and self-adjust the dose according to the intensity of their symptoms (up to 150mg/day). Patients evaluated by the assessment of the intensity of symptoms, by analogue visual scale, neuro-otological examination (presence of spontaneous nystagmus, Romberg test, Fukuda test and head-shaking nystagmus) and need to use the medication. There were three appointments in the follow-up period: three to five days, seven to ten days and eighteen to twenty one days after the initial evaluation. Results: There were 87 patients eligible for the study, 45 in the intervention group and 42 in the control group. At the initial evaluation, there was no statistically significant difference between the intervention and control groups in terms of sex, age, interval from onset of symptoms to inclusion in the study, intensity xxxvii of symptoms and neuro-otological tests results. Intensity of symptoms: the mean of the patients\' analogue visual scale score was similar for the intervention and control groups at the initial evaluation. At the second and third evaluations the mean score of the intervention group was significantly smaller. At the fourth and final evaluation, the groups were similar again. In the intervention group the amount of medication used by patients was always smaller than in the control group. Presence of spontaneous nystagmus was similar in between the groups at all but the third evaluation. As to the Romberg test results, the proportion of patients with a positive test was smaller for the intervention group at the second and third evaluations (borderline significant for the second intervention). At the fourth and final evaluation, the groups were similar again. As to the Fukuda and headshaking nystagmus tests, results were similar, at the third and forth evaluations the intervention group performed better than the control group. Conclusions: Vestibular exercises for adaptation of the vestibulo-ocular reflex have beneficial effects on treatment of patients with acute vertigo. The intervention group recovered faster, used a reduced amount of medication and performed better on balance tests as compared to the control group

Déficit de equilíbrio corporal: prevalência e fatores associados em idosos residentes no município de São Paulo - Estudo SABE / Balance disorder: prevalence and associated factors in elderly residents in São Paulo - SABE Study

Bushatsky, Angela 04 June 2012 (has links)
Introdução: O déficit de equilíbrio tem grande impacto na vida do indivíduo idoso, gera instabilidade, muitas vezes incapacitante, restrição de movimento, predisposição a quedas e fraturas. Tais fatores podem levar ao aumento da morbimortalidade, diminuição da independência e altos custos com tratamentos, internações e cuidados especiais, para as famílias e para a sociedade. Objetivo: Analisar a prevalência de alteração do equilíbrio corporal, investigar as características (demográficas, de saúde, antropométricas e de estilo de vida) e fatores associados ao déficit de equilíbrio, sua associação com o auto-relato de presença de tontura ou vertigem, bem como avaliar a influência do equilíbrio nos desfechos clínicos adversos e estimar a taxa de incidência no período 2006-2010. Material e método: Este estudo epidemiológico transversal, de base populacional domiciliar, desenvolvido no âmbito do Estudo SABE, na cidade de São Paulo, avaliou os idosos que em 2006 fizeram o Teste de Equilíbrio. Os dados obtidos foram analisados de forma descritiva e pelos modelos de regressão logística linear simples e múltiplo. Resultados: Entre os 1226 idosos avaliados, 83,7 por cento tiveram a pontuação máxima no teste. Idade, história de fratura, dificuldade em pelo menos uma mobilidade, declínio cognitivo, episódio de queda nos últimos 12 meses exerceram significativa influência no desempenho do equilíbrio e as associações foram estatisticamente significativa (p<0,05). A atividade física e o uso de bloqueadores de canal de cálcio mostraram-se como fatores que aumentam o desempenho no teste. O aumento de um ponto no Teste de Equilíbrio reduz em 27 por cento a chance do idoso ter sido internado no ano anterior, além de redução de 18 por cento de queda no mesmo período. Conclusão: Entre os idosos, medidas objetivas de desempenho no Teste de Equilíbrio foram superiores ao auto-relato de presença de tontura ou vertigem e podem fornecer informações sobre o estado funcional que não são obtidas a partir de medidas auto-referidas. As medidas de equilíbrio se mostraram preditivas de internação hospitalar - aqueles idosos que apresentam melhor equilíbrio têm menor probabilidade de serem internados. / Introduction: Balance disorder has great impact on the lives of the elderly, causing instability, often disabling, movement restriction and predisposition to falls and fractures. These factors may lead to increased morbimortality, decreased independence and costly treatments, hospitalizations and special care imposed on families and society. Objective: This study aims to analyze the prevalence of alterations in body balance and investigates the characteristics (demographic, health, anthropometric and lifestyle issues) and factors related to balance disorder as well as its association with self-reported presence of dizziness/vertigo. It also investigates the influence of balance in adverse clinical outcomes and estimates the incidence rate in the 2006-2010 period. Methods: This epidemiological cross-sectional population-based research, developed under SABE Study in São Paulo, evaluated the elderly who undertook the Balance Test in 2006. The data were analyzed descriptively and according to multiple and simple linear logistic regression models. Results: From a total of 1,226 elderly individuals evaluated, 83.7 per cent achieved the highest score on the test. Factors such as age, fracture history, difficulty in at least one mobility, cognitive decline and fall episode in the previous year had major influence on the balance performance and associations were statistically significant (p<0.05). Physical activity and use of calcium channel blockers were identified as factors that improved thperformance on the test. An increase by one point in the Balance Test reduces by 27 per cent the chances of the individual having been hospitalized in the previous year. Conclusion: Among the elderly, objective measures of performance on the Balance Test were higher than self-reported incidence of dizziness or vertigo and can provide information on functional status that is not obtained from self-reported measures. Balance measures proved to be predictive of hospitalization elderly individuals who have better balance are less likely to be hospitalized
