Objective: to verify the effect of a vestibular rehabilitation program on workers with dizziness from the Division of Nutrition and Dietetics at a University Hospital. Methods: a total of 13 employees between 42 and 65 years of age participated, of whom, 1 was male, and 12, females. They were evaluated before and after the vestibular rehabilitation program using the Dizziness Handicap Inventory, Work Ability Index and Visual Analog Scale. The program was conducted in groups at the workplace. Statistical analysis was performed using the analysis of variance test for paired factors and the chi-square test. Results: in the pre-and post-vestibular rehabilitation comparison, significant differences were found in the Dizziness Handicap Inventory and Visual Analogue Scale scores. In the qualitative analysis of the Work Ability Index, an increase was observed in the number of workers who considered their ability to work to have improved. Conclusion: vestibular rehabilitation conducted in groups and in the working environment was effective in improving dizziness complaint in workers at the Division of Nutrition and Dietetics. It is believed that the positive experience of this program may be extended to other areas.
A total of 120 Pekin ducks were distributed at random into four experimental groups, vaccinated or not against Newcastle disease (ND): G1 (Ulster 2C strain), G2 (B1 strain), G3 (LaSota strain), and G4 (nonvaccinated group). At 60 days of age, all groups were challenged with a pathogenic ND virus (NDV) suspension, and a group of specific pathogen free (SPF) chicks (G5) was also inoculated. Cloacal and tracheal swabs from all birds were collected after six, 14, 20, and 30 days post-challenge for virus isolation. NDV was isolated in 100% of SPF chicks. Pekin ducks from all groups, vaccinated or not, did not show any ND clinical signs, demonstrating that these birds are not susceptible to ND clinical disease. In the control group (G4), the virus was isolated 20 to 30 days after challenge, suggesting their possible NDV carrier state. In the vaccinated groups, no virus was isolated. This demonstrates that vaccination of white Pekin ducks against NDV is important to reduce NDV shedding in the field
INTRODUÇÃO: Com o aumento da população idosa, fica evidente a importância de compreender e explorar o processo de envelhecimento humano, o qual acarreta transformações morfológicas e funcionais. OBJETIVOS: Avaliar e comparar as inclinações anteroposterior e lateral do centro de gravidade por faixas etárias. MÉTODOS: Estudo transversal e exploratório. Fizeram parte da pesquisa 135 sujeitos, separados em faixas etárias: Grupo 1: 20-29 anos (n=26), Grupo 2: 30-39 anos (n=26), Grupo 3: 40-49 (n=25), Grupo 4: 50-59 anos (n=30) e Grupo 5: >60 anos (n=28). Esses sujeitos foram selecionados de acordo com o escore do Miniexame de Estado Mental e pela capacidade de permanecer em pé por, pelo menos, 90 segundos. As posturas foram avaliadas por meio do software de avaliação postural (SAPO). As comparações entre os valores de inclinações dados pelo SAPO foram feitas pelo teste de Mann-Whitney (comparação par-a-par), sendo aceito um valor de p<0,05 como significante. RESULTADOS: Na comparação da média da assimetria frontal entre as faixas etárias, observa-se maior lateralização com o avançar da idade, com valores significativos nos grupos 50-59 e >60 anos. Na comparação da média da assimetria sagital entre as faixas etárias, valores são significativos no grupo dos >60 anos. CONCLUSÕES: Após avaliar e comparar as assimetrias sagitais e frontais, pode-se apontar que na medida em que a idade avança, há tendência ao aumento de suas projeções anteriores e laterais comparadas ao centro de gravidade.
ResumoIntrodução: A análise biomecânica da marcha se mostra eficiente na identificação de alterações nos padrões de movimento e no declínio funcional. Objetivo: Analisar o efeito da dupla tarefa sobre os parâmetros espaçotemporais da marcha. Métodos: Participaram 32 sujeitos de ambos os sexos com idade entre 18 e 25 anos. O teste Timed Up and Go foi aplicado sob duas condições: na forma original e associado à tarefa cognitiva (verbalizar os meses do ano em ordem inversa). Foi avaliado o tempo total de execução, número de passos, cadência, tempo gasto para levantar, velocidade média e variabilidade do tempo de passo. Resultados: Com a adição da tarefa cognitiva, foram observadas mudanças em diversos dos parâmetros espaçotemporais da marcha analisados. Conclusão: Os testes realizados mostraram que o incremento de tarefas cognitivas durante a deambulação pode acarretar alterações no desempenho desta atividade.Descritores: Biomecânica; Equilíbrio postural; Marcha. AbstractIntroduction: Biomechanical analysis of gait can be used effectively to identify changes in movement patterns and functional decline. Objective: To analyze the effect of dual task on gait spatio-temporal variables. Methods: The sample was made up of 32 subjects of both genders aged between 18 and 25 years. The test Timed Up and Go was performed under two conditions: original form and associated with a cognitive task (verbalize backwards the months of the year). We evaluated the total execution time, number of steps, cadence, time spent to lift, average speed and variability of the step time. Results: Significant changes were observed with the addition of the cognitive task in many gait spatio-temporal variables analyzed. Conclusion: The tests showed that the increase of cognitive tasks during walking may lead to changes in the performance of this task.
