Dynamic Postural Stability in Patients with Neurological Disorders
No full textDynamic postural stability is a complex multifactorial system in which motor, sensory, and cognitive components interact. This information is integrated by the central nervous system in a continuous sensory reweighting that ensures postural control in both static and dynamic conditions. This chapter analyzes the state of the art of instrumented assessment of dynamic stability in the main neurological pathologies such as stroke, Parkinson’s disease, cerebellar ataxia, and cerebral palsy. Finally, the translational implications in the field of neurorehabilitation and future perspectives are discussed
Effectiveness of intensive neurorehabilitation in obese subacute stroke patients
No full textThe relationship between abdominal subcutaneous adipose tissue thickness (aSAT), body fat percentage (BFP), waist-to-hip ratio (WHR) and body mass index (BMI) and outcome measures of neurological deficit and functional recovery was evaluated in obese sub-acute stroke patients before and after neurorehabilitation. Decreased National Institutes of Health Stroke Scale (p = 0.0001) and modified Rankin Scale (mRS) (p = 0.002) scores, as well as increased Barthel Index (p = 0.0001) scores were detected after neurorehabilitation. Decreased BMI, aSAT, BFP and WHR observed after neurorehabilitation did not penalize the overall functional recovery as shown by correlations between the clinical measure scores and fat mass indices. The correlation observed after neurorehabilitation between BMI and mRS (rho = 0.4526, p < 0.05) suggests that a high BMI may compromise functional recovery. Monitoring of body fat mass indices may provide information aimed at improving the disability of obese stroke patients

Get PDFHere we reviewed the last evidence on the application of electroencephalography (EEG) as a non-invasive and portable neuroimaging method useful to extract hallmarks of neuroplasticity induced by virtual reality (VR) rehabilitation approaches in stroke patients. In the neurorehabilitation context, VR training has been used extensively to hamper the effects of motor treatments on the stroke’s brain. The concept underlying VR therapy is to improve brain plasticity by engaging users in multisensory training. In this narrative review, we present the key concepts of VR protocols applied to the rehabilitation of stroke patients and critically discuss challenges of EEG signal when applied as endophenotype to extract neurophysiological markers. When VR technology was applied to magnify the effects of treatments on motor recovery, significant EEG-related neural improve-ments were detected in the primary motor circuit either in terms of power spectral density or as time-frequency domains
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Breaking the ice through an effective translationality in neurorehabilitation: are we heading to the right direction?
No full textIntroduction: Translational medicine has been facing a persistent crisis for decades, and the field of neurorehabilitation is no exception. The challenges and delays that prevent patients, caregivers, and clinicians from promptly benefiting from advancements in bioengineering and new technological discoveries are well-documented. Areas-covered: This perspective presents some ideas to underline the consolidated problems and highlight new obstacles to overcome in the context of translational neurorehabilitation, also considering the increasingly stringent laws for medical devices that are emerging throughout the world. Expert opinion: The objective of the entire medical-scientific community must be to ensure that patients and their loved ones receive the best care available with the most advanced systems. Bioengineers, healthcare policy makers, certifiers and clinicians must always take translational aspects into consideration and find solutions to mitigate possible problems and delays. The goal of the entire medical and scientific community should be to ensure that patients and their families receive the highest quality care through the most advanced systems. To achieve this, bioengineers, healthcare policymakers, certifiers, and clinicians must consistently address translational challenges and work collaboratively to find solutions that minimize potential problems and delays
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
