TL;DR: In this article, the results of un proceso de revision bibliografica sobre rehabilitation of miembro superior basada en ambientes virtuales were presented.
Abstract: En este articulo se presentan los resultados de un proceso de revision bibliografica sobre rehabilitacion de miembro superior basada en ambientes virtuales. El estudio parte de los siguientes interrogantes sobre el estado actual del conocimiento en el area mencionada: ?como inciden los entornos virtuales frente a la rehabilitacion tradicional?, ?que metricas de desempeno se han aplicado en la rehabilitacion virtual de miembro superior? y ?que dispositivos hardware se utilizan en rehabilitacion virtual?. Para responder las anteriores preguntas se realizo una busqueda de articulos cientificos en el motor de busqueda Google Scholar y en las bases de datos PubMed, HINARI, ProQuest y Science Direct. De la revision realizada se concluyo que pese a la existencia de decenas de indices de desempeno para cuantificar la habilidad motriz, no existen criterios para seleccionar el indice que mejor se adapta a los objetivos de un determinado proceso de rehabilitacion

TL;DR: In this paper , a study of 15 mallas curriculares de trabajo social de universidades latinoamericanas is presented, with the aim of identifying the manera más idónea de generar conocimiento desde and for el trabajo social.
Abstract: Este artículo busca entregar fundamentos para reconocer en la investigación-acción, en adelante IA, la manera más idónea de generar conocimiento desde y para el trabajo social. Es un estudio con enfoque cualitativo de tipo descriptivo y que utiliza la técnica de revisión documental de la literatura científica e institucional. Se analizan 15 mallas curriculares de trabajo social de universidades latinoamericanas. Los resultados indican una importante presencia de publicaciones indexadas, especialmente en base de datos Wos, pero que conceptualmente evidencia confusión entre distintas metodologías participativas; se verifica la importancia de la IA en la identidad del trabajo social, siendo parte de los propios procesos de transformación de la disciplina; y, la desconexión de esta importancia con las propuestas formativas actuales. Las carreras de trabajo social analizadas no presentan asignatura de IA, lo cual evidencia una disociación entre lo que la literatura indica y los lineamientos formativos.

TL;DR: A systematic review of 7 clinical trials showing improvement in functionality, quality of life, and motivation with the use of virtual reality technologies in the rehabilitation of upper limbs of individuals with Duchenne muscular dystrophy found virtual reality can be a great tool for physiotherapy.
Abstract: Background: Duchenne muscular dystrophy is a serious and progressive disease affecting one in 3500-6000 live male births. The use of new virtual reality technologies has revolutionized the world of youth rehabilitation. Objective: We performed a systematic review to study the effectiveness of the use of virtual reality systems applied in the rehabilitation of the upper limbs of individuals with Duchenne muscular dystrophy. Methods: Between June 2018 and September 2019, we carried out a series of searches in 5 scientific databases: (1) PubMed, (2) Web of Science, (3) Scopus, (4) The Cochrane Library, and (5) MEDLINE via EBSCO. Two evaluators independently conducted the searches following the PRISMA recommendations for systematic reviews for articles. Two independent evaluators collated the results. Article quality was determined using the PEDro scale. Results: A total of 7 clinical trials were included in the final review. These studies used new technologies as tools for physiotherapeutic rehabilitation of the upper limbs of patients with Duchenne muscular dystrophy. Collectively, the studies showed improvement in functionality, quality of life, and motivation with the use of virtual reality technologies in the rehabilitation of upper limbs of individuals with Duchenne muscular dystrophy. Conclusions: The treatment of neuromuscular diseases has changed in recent years, from palliative symptom management to preventive methods for capacity building. The use of virtual reality is beginning to be necessary in the treatment of progressive diseases involving movement difficulties, as it provides freedom and facilitates the improvement of results in capacity training. Given that new technologies are increasingly accessible, rehabilitation and physiotherapy programs can use these technologies more frequently, and virtual reality environments can be used to improve task performance, which is essential for people with disabilities. Ultimately, virtual reality can be a great tool for physiotherapy and can be used for Duchenne muscular dystrophy rehabilitation programs to improve patient performance during training.

TL;DR: A mechatronic system to help patients to recover hand-eye coordination which requires movement of the whole arm and that is reliable and that can be replicated as needed is proposed.
Abstract: The people that need rehabilitation have grown and have overwhelmed therapists therefore new technological advances are required to provide service to a larger population, also the cost is a factor to consider. Particularly, the people who has suffered and survive a stroke (cerebral sudden malfunction) usually need therapy to recover lost functions, such as neuromuscular coordination. In this work, we propose a mechatronic system to help patients to recover hand-eye coordination which requires movement of the whole arm. The preliminary results show that the system is ready to be validated with real patients, that is reliable and that can be replicated as needed.

TL;DR: In this paper, a six-channel system for acquisition and conditioning of electromyographic signals collected in the upper limb is presented, which can be used as rehabilitation and training instrument for potential users of myoelectric prostheses.
Abstract: Resumen: Este trabajo describe el diseno y desarrollo de un sistema capaz de adquirir senales electromiograficas de superficie, digitalizarlas y procesarlas en una computadora personal, para ser usadas como control de un objeto de realidad virtual que representa al miembro superior. La clasificacion de la intencionalidad del usuario se realiza mediante la configuracion y entrenamiento de una red neuronal artificial. Luego se presenta en tiempo real la animacion en realidad virtual de los movimientos realizados por el miembro superior. Los resultados para los cuatro voluntarios estudiados, indican una tasa de clasificacion positiva en promedio del 75% para cada uno de ellos. Abstract: This work presents the design and development of a six-channel system for acquisition and conditioning of electromyographic signals collected in the upper limb. The main objective of the work is to create a system that can be used as rehabilitation and training instrument for potential users of myoelectric prostheses. The software developed perform actions of feature extraction, classifier training and design of the mechanical model of the human arm, with the running movements of flexion, extension, pronation and supination of the forearm and the grasp in a reality environment virtual, providing rehabilitation therapy to different patients. Sumario ─ Este trabalho apresenta a concepcao e desenvolvimento de um sistema de seis canais para a aquisicao e condicionamento de sinais eletromiograficos coletados no membro superior. O principal objetivo do trabalho e criar um sistema que pode ser utilizado como instrumento de reabilitacao e treinamento para os potenciais utilizadores de protese mioeletrica. O software desenvolvido executar acoes de extracao de caracteristicas, o treinamento do classificador e design do modelo mecânico do braco humano, com os movimentos da corrida de flexao, extensao, pronacao e supinacao do antebraco e do alcance em um ambiente de realidade virtual, fornecendo terapia de reabilitacao para diferentes pacientes.
