Test-retest reliability and synchronous status of heart rate recorded in vivo in children with phobic disorder

Chapunoff, Alexander J. 10 July 1992 (has links)
The present study assesses the synchrony and test-retest reliability of the three fear response systems in clinically diagnosed phobic disordered (experimental subjects) and non-phobic children (controls). Subjects (five boys and one girl, aged seven to sixteen, in each group) underwent three in vivo phobic assessments, each including a measure of self-report of fear (subjective), degree and duration of approach (behavioral) and heart rate (physiological), resulting in a total of 36 assessments. Synchrony coefficients for both groups indicated low inter-relationships among the systems. Test-retest coefficients of heart rate indicated moderate-to-very high reliability, with reliability being somewhat higher for phobics. Test-retest coefficients of the subjective and behavioral measures indicated high reliability for both groups, particularly the controls. Implications of the results are discussed with respect to the synchrony and assessment of the response systems. Future research directions are delineated.

Medo de altura: desempenho cognitivo e controle postural / Fear of heights: cognitive performance and postural control

Boffino, Catarina Costa 16 April 2009 (has links)
Fobia específica de altura ou acrofobia é um transtorno de ansiedade caracterizado pelo medo intenso e desproporcional de locais altos, levando à esquiva de situações e capaz de gerar sofrimento. Os diversos tipos de fobias parecem estar ligados a diferentes mecanismos de aquisição de medos. Mais do que experiências de aprendizado ou condicionamento, existem evidências de que anormalidades no controle da postura possam estar envolvidas na gênese do medo de altura. Deficiências na função vestibular podem levar um indivíduo a depender mais de sua visão ou de sua propriocepção para manter o controle postural. Lugares altos são um tipo de situação limite onde a falta de tais referências poderiam, em tese, desencadear reações de defesa e sintomas ansiosos. Além disso, o aumento de demanda por recursos cognitivos para a compensação do equilíbrio poderia deixar indivíduos acrofóbicos mais susceptíveis a interações entre o controle postural e atividades que demandem atenção. Esta dissertação testou a hipótese de que indivíduos com fobia específica de altura apresentam pior controle postural e maior interferência entre o controle do equilíbrio e o desempenho em tarefas que demandem atenção. Foram comparados 31 acrofóbicos (23 mulheres, 36,4±12 anos) e 34 controles não-fóbicos (22 mulheres, 32,4±12 anos). O desempenho da estabilidade postural em plataforma de posturografia dinâmica e o desempenho atencional foram simultaneamente avaliados através de teste em computador envolvendo o rastreio visual de um alvo em movimento imprevisível. Foram avaliadas as seguintes variáveis: ÁREA (área delimitada da excursão do centro de pressão em cm²); CPx e CPy (deslocamento total do centro de pressão na base de suporte em cm, na direção látero-lateral (eixo x) e ântero-posterior (eixo y)); VMx e VMy (velocidade média com a qual ocorre o deslocamento do centro de pressão em cm/s) e RMSx e RMSy (quadrado da média da raiz do deslocamento do centro de pressão, em cm, a partir da coordenada central (0,0) da base de apoio). O teste de atenção foi avaliado pela porcentagem de tempo em que o sujeito conseguia seguir anualmente o movimento do alvo. Indivíduos com acrofobia apresentaram uma pior estabilidade postural e um pior desempenho no teste atencional, além de uma maior interferência entre as tarefas. Estes resultados são compatíveis com a hipótese de que anormalidades do controle postural possam exercer um papel importante na gênese e na perpetuação dos sintomas de medo de altura. / INTRODUCTION: Fear of heights or acrophobia, is one of the most frequent subtypes of specific phobia frequently associated to depression and other anxiety disorders. Previous evidence suggests a correlation between acrophobia and abnormalities in balance control, particularly involving the use of visual information to keep postural stability. This study investigates the hypotheses that (1) abnormalities in balance control are more frequent in individuals with acrophobia even when not exposed to heights; (2) acrophobic symptoms are associated to abnormalities in visual perception of movement; and (3) individuals with acrophobia are more sensitive to balance-cognition interactions. METHOD: Thirty-one individuals with specific phobia of heights (23 women, 36.4±12 years) and thirty one non-phobic controls (22 women, 32.4±12 years) were compared using dynamic posturography and a manual tracking task. RESULTS: Acrophobics had poorer performance in both tasks, especially when carried out simultaneously. Previously described interference between posture control and cognitive activity seems to play a major role in these individuals. DISCUSSION: The presence of physiologic abnormalities is compatible with the hypothesis of a non-associative acquisition of fear of heights, i.e., not associated to previous traumatic events or other learning experiences. Clinically, this preliminary study corroborates the hypothesis that vestibular physical therapy can be particularly useful in treating individuals with fear of heights.
