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.

Redes multi-niveles de derechos humanos y defensa de los pueblos indígenas colombianos en escenarios “internacionalizados”

Este artículo busca analizar uno de los múltiples aspectos de la dimensión internacional de las movilizaciones indígenas: la forma como los procesos reivindicativos de las organizaciones indígenas colombianas se insertan en la dinámica global del lobbying internacional de las redes de derechos humanos ante Naciones Unidas. Para ello, nos centraremos en el análisis de la lógica de funcionamiento de los circuitos de derechos humanos en un universo social específico: el medio asociativo francés. Esto nos permitirá llevar a cabo la reconstrucción de algunos perfiles sociales de militantes y juristas que hacen las veces de intermediarios entre organizaciones colombianas y ONG europeas.-----This article seeks to analyze one of the multiple aspects of the international dimension of indigenous congregations: how the claim processes of the Colombian indigenous organizations fit into the global dynamics of international lobbying by human rights networks before the United Nations. For this purpose we shall focus our argument around analyzing the rationale of the way human rights circuits work in a specific social universe: the French associative media. This will allow us to undertake the reconstruction of some of the social profiles of militants and lawyers who act as intermediaries between Colombian organizations and European NGO's.
