Étude des interactions interhémisphériques entre les représentations des muscles de l'épaule et du tronc dans le cortex moteur primaire.

Après un accident vasculaire cérébral (AVC), 30% des personnes ont une atteinte de la fonction motrice du membre supérieur. Un des mécanismes pouvant intervenir dans la récupération motrice après un AVC est la réorganisation des interactions interhémisphériques. À ce jour, la plupart des études se sont intéressées aux interactions entre les représentations des muscles de la main. Or la réalisation de mouvements de la main nécessite une coordination précise des muscles proximaux de l’épaule et le maintien d’une stabilité assurée par les muscles du tronc. Cependant, il existe peu d’informations sur le contrôle interhémisphérique de ces muscles. Ainsi, l’objectif de cette étude était de caractériser les interactions entre les représentations corticales des muscles proximaux (Deltoïde antérieur (DA)), et axiaux (Erecteur spinal (ES L1)) chez le sujet sain et de les comparer avec les interactions interhémisphériques entre les représentations des muscles distaux (1er interosseux dorsal (FDI)). Deux techniques de stimulation magnétique transcrânienne ont été utilisées pour évaluer ces interactions. La stimulation du cortex moteur ipsilatéral évoque une période de silence ipsilatérale (iSP)-reflétant l’inhibition interhémiphérique-dans le FDI et le DA. Dans ES L1, l’iSP est précédée d’une facilitation. Le paradigme de l’impulsion pairée démontre aussi la présence d’inhibition interhémisphérique dans les trois muscles. Ces résultats suggèrent un patron distinct d’interactions réciproques entre les représentations des muscles distaux, proximaux et axiaux qui peut être expliqué à la fois par des changements d’excitabilité au niveau cortical et sous-cortical. Ces résultats pourraient servir de bases normatives afin d’évaluer les changements survenant suite à un AVC.

Aggressive incidents inside a Montreal barroom involving patrons, barmaids and bouncers : a micro level examination of routine activity theory

Objectives: This article further examines the phenomenon of aggression inside barrooms by relying on the “bouncer-ethnographer” methodology. The objective is to investigate variations in aggression through time and space according to the role and routine of the target in a Montreal barroom. Thus, it provides an examination of routine activity theory at the micro level: the barroom. Methods: For a period of 258 nights of observation in a Canadian barroom, bouncers completed reports on each intervention and provided specific information regarding what happened, when and where within the venue. In addition, the bouncer-ethnographer compiled field observations and interviews with bar personnel in order to identify aggression hotspots and “rush hours” for three types of actors within barrooms: (a) bouncers, (b) barmaids and (c) patrons. Findings: Three different patterns emerged for shifting hotspots of aggression depending on the target. As the night progresses, aggressive incidents between patrons, towards barmaids and towards bouncers have specific hotspots and rush hours influenced by the specific routine of the target inside the barroom. Implications: The current findings enrich those of previous work by pointing to the relevance of not only examining the environmental characteristics of the barroom, but also the role of the target of aggression. Crime opportunities follow routine activities, even within a specific location on a micro level. Routine activity theory is thus relevant in this context, because as actors in differing roles follow differing routines, as do their patterns of victimization.

Gender Bias and Caste Exclusion in Engineering Admission: Inferences from the Engineering Entrance Examination in Kerala

The major problem of the engineering entrance examination is the exclusion of certain sections of the society in social, economic, regional and gender dimensions. This has seldom been taken for analysis towards policy correction. To lessen this problem a minor policy shift was prepared in the year 2011 with a 50–50 proportion in academic marks and entrance marks. The impact of this change is yet to be scrutinized. The data for the study is obtained from the Nodal Centre of Kerala functioning at Cochin University of Science and Technology under the National Technical Manpower Information System and also estimated from the Centralized Allotment Process. The article focuses on two aspects of exclusion based on engineering entrance examination; gender centred as well as caste-linked. Rank order spectral density and Lorenz ratio are used to cognize the exclusion and inequality in community and gender levels in various performance scales. The article unfolds the fact that social status in society coupled with economic affordability to quality education seems to have significant influence in the performance of students in the Kerala engineering entrance examinations. But it also shows that there is wide gender disparity with respect to performance in the high ranking levels irrespective of social groups

Archivo digital de imágenes diagnósticas enfocado a tórax y abdomen de Fundación Cardioinfantil – Instituto de Cardiología

Introducción: El desarrollo del archivo docente de imágenes diagnósticas, permite al Departamento de Imágenes compartir y difundir el conocimiento de la colección de casos e imágenes radiológicas reales con mayor rapidez y facilidad en el acceso a las mismas por parte de todo el personal de la Clínica Fundación Cardio-Infantil – Instituto de Cardiología, a través por portal web “e-cardio”, contribuyendo así en la formación académica del personal médico, técnico y administrativo. Metodología: Este trabajo no responde a ningún tipo de estudio epidemiológico, sino a una colección de imágenes y reseñas radiológicas de casos de patología torácica y cardiovascular, procedentes de pacientes de la Fundación Cardioinfantil – Instituto de Cardiología, con el fin de conformar un archivo digital docente. Resultados: Se recolectaron 1.148 radiografías impresas, previamente rotuladas según el Index for Radiological Diagnoses 4 edición y de archivos individuales 3.512 imágenes. Utilizando los criterios de inclusión y exclusión, se realizó la selección de imágenes para continuar el procedimiento. Se descartaron 278 radiografías impresas por no tener rotulo, estar en mal estado general, o rotulación incorrecta. En el caso de los archivos digitales, se descartaron 1435 imágenes, utilizando el mismo procedimiento. Conclusión: Iniciar la conformación y montaje del primer archivo docente de la Clínica Fundación Cardioinfantil – Instituto de Cardiología. Motivar a los profesionales médicos de la Clínica Fundación Cardio Infantil, y especialmente a los residentes de Radiología, para que estén en un proceso de aprendizaje continúo, fortaleciendo su autoevaluación, y todo ello para beneficio final de los pacientes y de la misma Institución.

The Role of Kinaesthetic Motor Imagery in Promoting Activation of the Lumbrical Muscles in the Hemiparetic Hand: a Randomised Controlled Study

The objective of the investigation who gave as result this work was to investigate the effectiveness of kinaesthetic motor imagery in the activation of the hemiplegic hand muscles following stroke. The experiment consisted of two random groups. Movements were measured after treatment. The participants were ten patients with hemiplegic hands (men who mean age was 74.4 years; mean time since stroke 3.05 months). All patients received three sessions of physical treatment based on an identical treatment protocol. Five patients were randomly assigned to an experimental group practising kinaesthetic motor imagery of a grasp using the 'lumbrical action' (experimental group). The others five (control group) followed a relaxation script. All the patients were then asked to grasp an object using the 'lumbrical action'. The grasps were recorded using an optoelectronic motion capture system. The magnitude of the extension of the index finger and the correlation of the angular displacement of the proximal phalangeal joints and the metacarpophalangeal joints were calculated. The movement time for the whole grip was calculated. The experimental group demonstrated higher extension in the index finger (p = < 0.01) and they had a higher correlation coefficient (0.99) than the control group (0.77) for the displacement of the proximal interphalangeal joint and the metacarpophalangeal joints. The movement time for the experimental group was faster, although the difference was not significant.
