Antagonist coactivation of muscles of ankle and thigh in post-stroke vs. health...

This study aims to analyse the coactivation of antagonist muscles of the thigh and ankle during the sit-to-stand task in post-stroke subjects, specifically during forward and antigravity sub-phases. A group of 18 healthy subjects and another with 18 subjects with a history of stroke participated voluntarily in this study. Bilateral surface electromyography (EMGs) of the soleus, gastrocnemius medialis, tibialis ...

Sistema computacional para determinação da taxa de diluição em soldadura

Diluição da solda é a modificação da composição química do metal de adição, causada pela parcela do metal de base que sofreu fusão e passou a compor a zona fundida. Sendo dada pela percentagem do metal de base que participa na formação do cordão de solda. A sua medição, em geral, é obtida manualmente utilizando-se softwares genéricos de desenho ou de processamento e análise de imagem. Neste sentido, o presente ...

Optimizing a medical image registration algorithm based on profiling data for r...

Made available in DSpace on 2022-04-28T19:46:39Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Image registration is a commonly task in medical image analysis. Therefore, a significant number of algorithms have been developed to perform rigid and non-rigid image registration. Particularly, the free-form deformation algorithm is...

Users’ perceptions of signage systems at three portuguese hospitals

This article is a report on the quantitative data collected from patients, family members, and visitors using the outpatient areas of three hospitals in Portugal. It details the users’ views regarding the existing signage and presents suggestions to improve the design and implementation of the signage systems. A questionnaire was used with 1,287 respondents. The results showed that almost all users had a positi...

Benchmark RGB-D gait datasets : a systematic review

Human motion analysis has proven to be a great source of information for a wide range of applications. Several approaches for a detailed and accurate motion analysis have been proposed in the literature, as well as an almost proportional number of dedicated datasets. The relatively recent arrival of depth sensors contributed to an increasing interest in this research area and also to the emergence of a new type...

GRIDDS - a gait recognition image and depth dataset

Several approaches based on human gait have been proposed in the literature, either for medical research reasons, smart surveillance, human-machine interaction, or other purposes, whose validation highly depends on the access to common input data through available datasets, enabling a coherent performance comparison. The advent of depth sensors leveraged the emergence of novel approaches and, consequently, the ...

New computational solution to compute the uptake index from 99m Tc-MDP bone sci...

The appearance of bone metastasis in patients with breast or prostate cancer makes the skeleton most affected by metastatic cancer. It is estimated that these two cancers lead in 80% of the cases to the appearance of bone metastasis, which is considered the main cause of death. 99mTc-methylene diphosphonate (99mTc-MDP) bone scintigraphy is the most commonly used radionuclide imaging technique for the detection ...

Healthcare signage design: a review on recommendations for effective signing sy...

This article provides a set of recommendations, selected from the systematic literature review carried out, regarding signage systems for healthcare institutions that can be used for designing or redesigning more competent signage systems. The signage systems in healthcare settings are usually poorly designed due to the expansion of the original facilities, a lack of awareness of existing guidelines by the deve...

Antagonist coativation in stroke vs healthy subjects during sit-to-stand

High levels og antagonista coativation is frequently found in post stroke subjects, related with postural control impairments. The bilateral postural control dysfunction expected in post-stroke subjects is due to the bilateral disposal of reticulospinal system.
