Effects of Repetitive Transcranial Magnetic Stimulation on Upper Extremity Spasticity Post-Stroke: A Systematic Review
No full textUpper extremity spasticity is one of the most popular impairments following stroke. It can reduce patients' functional level. Recently, repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising tool in stroke rehabilitation. This review was conducted to investigate the immediate and long-term effects of rTMS on the upper extremity spasticity post-stroke and determine the optimal treatment protocols. PubMed, SCOPUS, PEDro, CINAHL, MEDLINE, REHABDATA, AMED, and Web of Science databases were searched for randomized controlled trials investigating the effect of rTMS on the upper extremity spasticity in patients with stroke. The methodological quality was assessed using the Cochrane Collaboration's tool. Ten randomized clinical trials were met the inclusion criteria. A total of 225 patients were included in this analysis, 35.30% of whom were females. The mean age for all patients was 60.14 years. The findings showed heterogeneous evidence on the benefits of rTMS intervention in the upper extremity spasticity post-stroke. The evidence for the effect of rTMS on the upper extremity spasticity post-stroke is promising. Combining rTMS with other rehabilitation interventions may show a superior effect in reducing the upper extremity spasticity compared with rTMS intervention alone. Further randomized controlled trials with long-term follow-ups are warranted
Clinical effectiveness of focal muscle vibration on gait and postural stability in individuals with neurological disorders: A systematic review
No full textBackground: Gait deficits and postural instability are common impairments among patients with neurological disorders. These impairments limit function independence and decrease activities of daily living. Focal muscle vibration (FMV) produces vibration signals affecting the nervous system. No systematic review has been published examining the influence of FMV on gait ability and postural stability in individuals with neurological disorders.Objectives: This study aimed to investigate the effects of FMV on gait and postural stability parameters in individuals with neurological disorders.Methods: PubMed, Scopus, PEDro, REHABDATA, web of science, CHAINAL, EMBASE, and MEDLINE were searched from inception to July 2021. The methodological quality of the selected studies was evaluated using the Physiotherapy Evidence Database (PEDro) scale.Results: Five randomized controlled trials (RCTs) met the eligibility criteria. The scores on the PEDro scale ranged from seven to nine, with a median score of eight. The results showed evidence for the benefits and non-benefits of the FMV intervention on gait and postural stability in individuals with neurological disorders.Conclusions: The FMV intervention is safe and well-tolerated in individuals with neurological disorders. The evidence for the effects of FMV on individuals with neurological disorders was limited. Further high-quality studies with long-term follow-up are strongly needed
Transcutaneous spinal cord stimulation effects on spasticity in patients with spinal cord injury: A systematic review
No full textContext: Spasticity is one of the most prevalent impairments following spinal cord injury (SCI). It can lead to a decrease in the patient's functional level. Transcutaneous spinal cord stimulation (tSCS) has demonstrated motor function improvements following SCI. No systematic reviews were published examining the influences of tSCS on spasticity post-SCI. Objectives: This review aimed to investigate the effects of tSCS on spasticity in patients with SCI. Methods: PubMed, SCOPUS, PEDro, CINAHL, MEDLINE, REHABDATA, AMED, and Web of Science databases were searched until June 2021. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the selected studies. Results: Six studies met the inclusion criteria. Five studies were pilot studies, and one was a case series. The scores on the PEDro scale ranged from two to four, with a median score of four. The results showed heterogenous evidence for the effects of tSCS on spasticity reduction post-SCI. Conclusions: TSCS appears safe and well-tolerated intervention in patients with SCI. The evidence for the effectiveness of tSCS on spasticity in chronic SCI patients is limited. Further randomized controlled studies are strongly needed to study the effects of tSCS on patients with SCI

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
