A qualitative study exploring views and experiences of people with stroke undergoing transcranial direct current stimulation and upper limb robot therapy
No full textBackgroundNeurorehabilitation technologies used mainly in research such as robot therapy (RT) and transcranial direct current stimulation (tDCS) can promote upper limb motor recovery after stroke. Understanding the feasibility and efficacy of stroke rehabilitation technologies for upper limb impairments is crucial for effective implementation in practice. Small studies have explored views of RT by people with stroke; however experiences of people receiving tDCS in combination with RT have never been explored.ObjectiveTo explore views and experiences of people with sub-acute and chronic stroke that had previously taken part in a randomised controlled trial involving tDCS and RT for their impaired upper limb.MethodsAn interview study includes open and closed questions. Face-to-face interviews were audio recorded. Open-ended question responses were transcribed and analyzed using thematic analysis; closed questions were analyzed using descriptive analysis.ResultsParticipants felt that RT was enjoyable (90%) and beneficial for their affected arm (100%). From the open question data, it was found that the intervention was effective for the impaired arm especially in the sub-acute stage. Main reported concerns were that tDCS caused painful, itching and burning sensations and RT was sometimes tiring and difficult. Participants recommended that future research should focus on designing a more comfortable method of tDCS and develop a robot that promotes hand movements.ConclusionsThis study provides new knowledge about the benefits and barriers associated with these technologies which are crucial to the future effective implementation of these tools in practice.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Reliability of motor evoked potential resting threshold and amplitude of proximal and distal arm muscles in healthy adults
No full textObjectives: To quantify the intra-rater and test-retest reliability of the motor evoked potential (MEP) resting threshold (RT) and MEP amplitude of the anterior deltoid (AD) and extensor digitorum (ED) of healthy adults using Transcranial Magnetic Stimulation (TMS). Methods: Stimulation was performed on healthy adults with a Magstim® 2002 device using Brainsight® neuro-navigation. Surface EMG (Biometrics Ltd) was recorded from surface electrodes over AD and ED muscles. RT was defined as the minimal TMS intensity to recruit an MEP > 50 ?V in five of ten consecutive measurements in both muscles. Measurements were made on three occasions in each participant by the same assessor. Two measurements were carried out on day one with 30 minutes rest in between (tests 1 and 2) and the third measurement was carried out three days later (test 3). Mean peak to peak amplitude of five MEPs at RT were analysed using MATLAB.Results: Twenty participants (10 males and 10 females, mean age of 59.86 years ±11.70SD) completed the study. There was good to excellent reliability of RT for ED and AD between tests 1 and 2 (ICC=0.89 and 0.94 respectively) and tests 1 and 3 (ICC=0.84 and 0.77 respectively). MEP amplitude between tests 1 and 2 had a poor to moderate level of agreement (ICC=0.42 [ED] and 0.53 [AD]) and between tests 1 and 3, moderate to very poor agreement was found (ICC=0.62 [ED] and 0.14 [AD]).Conclusions: RT and MEP amplitude are regularly used as neurophysiological outcome measures in neurorehabilitation research. Measurement of the RT showed excellent intra-rater and test-retest reliability in healthy adults. Measurement of MEP amplitude at RT of both muscles showed poor to moderate agreement. RT provides less information about changes in cortical excitability, however, our results suggest RT to be a more reliable neurophysiological measurement, which could be included in future neurorehabilitation trials
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
