Análise de Dados de Falha de um Transmissor de Fibra Óptica
A análise de confiabilidade é uma metodologia utilizada para descrever o comportamento de falhas em equipamentos. O presente trabalho tem por objetivo modelar o tempo de vida de transmissores de fibra óptica. O procedimento de pesquisa utilizado foi o estudo de caso. Foram feitos testes em 14 equipamentos que falharam. O método gráfico e os testes de aderência de qui-quadrado e Kolmogorov-Smirnov (K-S) foram utilizados para verificar a distribuição que melhor modela a amostra de dados. Foi utilizado o software ProConf para fazer a análise. Os parâmetros da distribuição foram determinados. As funções de confiabilidade R(t) e de risco h(t) foram apresentadas. A distribuição Weibull foi escolhida para modelar o tempo até a falha dos dados. O tempo médio até a falha dos transmissores é de 318 horas. Metade dos equipamentos falharam antes de 236 horas. Os fatores de forma e escala da Weibull são, respectivamente, 1,47 e 357,50. A fase de vida dos transmissores de fibra óptica estudados corresponde ao inÃcio da mortalidade senil, já que o γ foi maior que1. Assim, tem-se risco crescente e confiabilidade decrescente, indicando um desgaste do equipamento
Validation of the Catherine Bergego Scale in patients with unilateral spatial neglect after stroke
ABSTRACT. The Catherine Bergego Scale (CBS) is a scale to evaluates the impact of unilateral spatial neglect (USN) on everyday life of patients after stroke. Objective: The aim of this study was to evaluate the reliability and comprehension of the Portuguese version of the CBS for patients with USN after stroke. Methods: This was a cross-sectional study in patients with stroke and USN. The CBS was translated, culturally adapted and applied by two independent investigators. The patients were also evaluated by the Behavioural Inattention Test (BIT), NIHSS, mRS and Barthel scale to assess USN severity, neurological function, disability and autonomy consecutively. Consistency and coherence were analysed using Cronbach’s α, inter-observer reliability by Kappa, and the correlation between the CBS, BIT, NIHSS, mRS, and Barthel was determined using Pearson correlation. Results: Twenty-two patients were evaluated and the observed Cronbach’s α=0.913. For intra-observer reproducibility, the 10 items showed a reasonable and high reliability between evaluators. The CBS showed a negative correlation with the BIT. There was a low correlation between the BIT and NIHSS, mRS and Barthel index. Conclusion: The CBS is an adequate and validated scale for assessing patients with USN after stroke in a Brazilian population
Effects of virtual reality therapy on upper limb function after stroke and the role of neuroimaging as a predictor of a better response
ABSTRACT Background: Virtual reality therapy (VRT) is an interactive intervention that induces neuroplasticity. The aim was to evaluate the effects of VRT associated with conventional rehabilitation for an upper limb after stroke, and the neuroimaging predictors of a better response to VRT. Methods: Patients with stroke were selected, and clinical neurological, upper limb function, and quality of life were evaluated. Statistical analysis was performed using a linear model comparing pre- and post-VRT. Lesions were segmented in the post-stroke computed tomography. A voxel-based lesion-symptom mapping approach was used to investigate the relationship between the lesion and upper limb function. Results: Eighteen patients were studied (55.5 ± 13.9 years of age). Quality of life, functional independence, and dexterity of the upper limb showed improvement after VRT (p < 0.001). Neuroimaging analysis showed negative correlations between the internal capsule lesion and functional recovery. Conclusion: VRT showed benefits for patients with stroke, but when there was an internal capsule lesion, a worse response was observed
A new tuning fork with different vibration frequencies as an aid to bronchopulmonary hygiene physiotherapy
Background: The main function of the mucociliary system is the removal of particles or substances that are potentially harmful to the respiratory tract. The tuning fork therapeutic for the purpose of bronchial hygiene has still not been described in the literature. The optimal vibration frequency to mobilize secretions is widely debated and varies between 3 and 25 Hz. It is expected that a tuning fork is able to generate vibrations in the thorax, facilitating bronchial hygiene. The aim of the present study is to develop tuning forks with different frequencies, for use in bronchopulmonary hygiene therapy. Methods: The first tuning fork was made with a fixed frequency of 25 Hz and it was recorded in the Brazilian institution of patent registration. This device generated a frequency of 25 Hz and had a weight of 521 g, with dimensions of 600 mm in total length. The device is characterized by a bottom end containing a transducer with a diameter of 62 mm and a thickness of 5/16 mm (8''), a rod removable 148 mm, fork length of 362 mm and an extension at the upper end of sinuous shape bilaterally.The tuning forks must be applied at an angle of 90° directly on the chest wall of the patient after pulmonary auscultation for location of secretions. The tuning fork is activated by squeezing the tips of the extensions together and releasing them in a sudden movement. Results: This study shows the result of the development of others three tuning forks of different dimensions to generate different frequencies. Each equipment reaches a fixed frequency preset of 12, 15 and 20 Hz measured by digital oscilloscope. Conclusions: The tuning fork models developed in this study generated different frequencies proposed by the scientific literature as effective in the mobilization of pulmonary secretions
