Βραχυπρόθεσμη επίδραση τεχνικών Χειροθεραπείας (Manual Therapy) στην κλινική εικόνα και στα επίπεδα του οξειδωτικού στρες σε ασθενείς με χρόνιο αυχενικό μηχανικό πόνο
No full textΕΙΣΑΓΩΓΗ: Ο χρόνιος μηχανικός αυχενικός πόνος μπορεί να οφείλεται σε αρκετούς παράγοντες, ένας από τους οποίους είναι και το οξειδωτικό στρες. Έχει δειχθεί ότι ένας από τους αποτελεσματικούς τρόπους βραχυπρόθεσμης αντιμετώπισης αυτού του είδους πόνου είναι η χειροθεραπεία. Η παρούσα μελέτη στοχεύει στη διερεύνηση της επίδρασης τεχνικών χειροθεραπείας στον χρόνιο μηχανικό αυχενικό πόνο και στο οξειδωτικό στρες αυτών των ασθενών. ΜΕΘΟΔΟΛΟΓΙΑ: Η μελέτη εφαρμόστηκε σε ασθενείς οι οποίοι έπασχαν από χρόνιο αυχενικό μηχανικό πόνο. Συμμετείχαν 32 εθελοντές ασθενείς, οι οποίοι χωρίστηκαν σε 3 ομάδες: 11 αποτελούσαν την ομάδα παρέμβασης και θεραπεύτηκαν με χειροθεραπεία, 11 αποτελούσαν την ομάδα εικονικής θεραπείας (SHAM χειροθεραπεία) και έλαβαν εικονική θεραπεία και 10 αποτέλεσαν μια έτερη ομάδα ελέγχου και δεν έλαβαν καμία θεραπεία. Λήφθηκαν δείγματα αίματος από τις ομάδες παρέμβασης, εικονικής θεραπείας και την έτερη ομάδα ελέγχου σε τρεις διαφορετικές συνθήκες: α) πριν την έναρξη μιας θεραπευτικής (ή της εικονικής) συνεδρίας, β) μετά από την ολοκλήρωσή της και γ) μετά την ολοκλήρωση της τελευταίας (ένατης) θεραπευτικής συνεδρίας. Η συνολική διάρκεια της μελέτης ήταν τρεις εβδομάδες και πραγματοποιήθηκαν εννέα συνεδρίες. Οι εξαρτημένες μεταβλητές της μελέτης ήταν ο πόνος, τα επίπεδα των λιπιδικών υδροϋπεροξειδίων (LOOH), ως δείκτη οξειδωτικού στρες και η λειτουργικότητα των ασθενών με χρόνιο μηχανικό αυχενικό πόνο, οι οποίες αξιολογήθηκαν στα ανωτέρω τρία χρονικά σημεία, πριν και μετά την παρέμβαση. ΑΠΟΤΕΛΕΣΜΑΤΑ: Παρατηρήθηκε μείωση των επιπέδων των LOOH στον ορό του αίματος των ασθενών ήδη από την πρώτη συνεδρία χειροθεραπείας, ενώ μεγαλύτερη μείωση παρατηρήθηκε μετά την ολοκλήρωση της ένατης θεραπείας. Οι ασθενείς που ακολούθησαν εικονική θεραπεία παρουσίασαν μικρότερη μείωση των επιπέδων των LOOH σε σύγκριση με την ομάδα παρέμβασης, η οποία παρέμεινε σταθερή ακόμη και μετά την ένατη θεραπεία. ΣΥΜΠΕΡΑΣΜΑ: Οι ασθενείς με χρόνιο μηχανικό αυχενικό πόνο στους οποίους εφαρμόστηκε χειροθεραπεία παρουσίασαν βελτίωση της κλινικής τους εικόνας, τόσο ως προς τον πόνο, όσο και ως προς τη λειτουργικότητά τους. Τα ευρήματα αυτά υποδηλώνουν ότι η χειροθεραπεία μπορεί να είναι μια αποτελεσματική μέθοδος στην αντιμετώπιση του χρόνιου μηχανικού αυχενικού πόνου και στη μείωση του οξειδωτικού στρες αυτών των ασθενών.INTRODUCTION: Chronic mechanical neck pain can be caused by several factors, one of which is oxidative stress, while it has been shown that Manual Therapy is one of the most effective ways to treat this type of pain. The present study aimed to investigate the effect of Manual Therapy techniques on chronic mechanical neck pain and oxidative stress in patients with chronic mechanical neck pain. METHODOLOGY: The study was performed on patients suffering from chronic mechanical neck pain. Thirty two volunteer patients were divided into 3 groups: 11 were the intervention group and were treated with Manual Therapy, 11 were the placebo group and received SHAM manual therapy and 10 formed another healthy control group that did not receive any treatment. Blood samples were taken from the intervention, placebo and healthy groups in three different conditions: a) before the start of a Manual Therapy (or placebo) session, b) after its completion and c) after the end of the last (ninth) treatment session. The study lasted three weeks and consisted of nine sessions. The dependent variables of the study were pain, lipid hydroperoxide (LOOH) levels as an indicator of oxidative stress, and functional ability of patients, which were evaluated at the above three time points, before and after the intervention. RESULTS: A decrease in serum LOOH levels was observed in patients after the completion of the first session of Manual Therapy, while a further decrease was observed after the end of the last treatment session. Patients that received placebo treatment exhibited a smaller reduction in LOOH compared with the intervention group, the reduction of which remained steady after the ninth treatment session. CONCLUSION: Patients with chronic mechanical neck pain showed an improvement in their clinical symptoms, both in terms of pain and functional ability, after treatment with Manual Therapy techniques. These findings suggest that Manual Therapy may be an effective method of treating chronic mechanical neck pain and reducing oxidative stress in those patients
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
SHORT-TERM EFFECTS OF MOBILIZATION-WITH-MOVEMENT (MWM) AND AUTO-MWM APPLICATION IN RECREATIONAL RUNNERS WITH ILIOTIBIAL BAND SYNDROME
No full textBackground: It is well known that Iliotibial band syndrome (ITBS) is the most frequent overuse injury in recreational runners. Given the fact that there are no clear guidelines on the optimal conservative treatment approach regarding ITBS rehabilitation, manual therapy effect by a functional joint mobilization is still unknown. The purpose of the study was to investigate whether implementation of mobilization-with-movement (MWM) and auto-mobilization had a significant short-term improvement in pain and functionality of recreational runners with ITBS. Methods: Participants: thirty ITBS patients, were randomly assigned into two groups. Design and Settings: One group pre-test / post-test with the control group. Interventions: Runners on the treatment group followed an MWM protocol of six sessions with an additive program of auto-MWM, while the control group received a SHAM form of MWM. Outcome measurements: Pain and functionality were measured at baseline and post-treatment, via Numeric Pain Rating scale and Lower Extremity Functional Scale respectively. Mixed-ANOVA test detected possible differences among treatment phases and between groups, but also interactions among factors. Result: The present findings revealed significant interactions between factors and significant main effects of each TIME and GROUP factors on pain and functionality. MWM-treatment group showed significant improvement in post-intervention NPRT and LEFS scores, compared to baseline scores (p<.001). SHAM- MWM group exhibited no significant differences on post-NPRT and LEFS scores, compared to baseline (p>.001). Differences between groups were significant in post-treatment scores (p<.001). Conclusion: Our findings suggest that MWM and auto-MWM are a significant treatment approach, improving pain and functionality in recreational runners suffering from ITBS
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
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
