Diseño de Exoesqueleto con base en Cuatro Casos de Estudio de Rehabilitación de Miembro Superior

LUIS ADRIAN ZUÑIGA AVILES GIORGIO MACKENZIE CRUZ MARTINEZ (2018)

En este artículo se presenta un enfoque para rehabilitación pasiva de miembro superior mediante la formulación de cuatro casos de estudio haciendo un análisis de las patologías y los ejercicios que se aplican. Para llevar a cabo la experimentación en los casos propuestos se registraron los datos de las trayectorias de las articulaciones del brazo de un paciente realizando los ejercicios de rehabilitación con un terapeuta. Se diseñó el exoesqueleto ERMIS de siete grados de libertad para emular los movimientos anatómicos en el brazo durante la rehabilitación a partir de los requerimientos de los casos de estudio. Para validar el funcionamiento del exoesqueleto en los casos se simuló el modelo dinámico del ERMIS y se compararon los datos con los datos muestreados de los ejercicios. Al final se presentan los resultados obtenidos de los ejercicios realizados con el exoesqueleto, obteniendo en la precisión un desempeño promedio del 95% en los movimientos de hombro, codo y muñeca al emular la terapia con timón.

This paper presents an approach for passive upper limb rehabilitation based on four case studies by analyzing the pathologies and exercises that are applied. To carry out the experimentation in the proposed cases, the data from the trajectories of the patient’s arm articulations were registered, performing the rehabilitation exercises with a therapist. The ERMIS exoskeleton´s seven degrees of freedom was designed to emulate the anatomical movements in the arm during rehabilitation from the requirements of the case studies. To validate the exoskeleton performance in the study cases, the ERMIS’s dynamic model was simulated and the data were compared with the sampled data of the exercises. At the end, the results obtained from exoskeleton exercises emulating rudder therapy, where shoulder, elbow and wrist movements were showed with an accuracy of 95%.

Design Methodology for Rehabilitation Robots: Application in an Exoskeleton for Upper Limb Rehabilitation

LUIS ADRIAN ZUÑIGA AVILES GIORGIO MACKENZIE CRUZ MARTINEZ (2020)

This article presents a methodology for the design of rehabilitation devices that considers factors involved in a clinical environment. This methodology integrates different disciplines that work together. The methodology is composed by three phases and 13 stages with specific tasks, the first phase includes the clinical context considering the requirements of the patient and therapist during the rehabilitation, the second phase is focused in engineering based on the philosophy of digital twin, and in the third phase is evaluated the device. This article explains the characteristics of the methodology and how it was applied in the design of an exoskeleton for passive rehabilitation of upper limb.

Design Criteria of Soft Exogloves for Hand Rehabilitation- Assistance Tasks

LUIS ADRIAN ZUÑIGA AVILES JUANA MARIEL DAVILA VILCHIS (2020)

This paper establishes design criteria for soft exogloves (SEG) to be used as rehabilitation or assistance devices. This research consists in identifying, selecting, and grouping SEG features based on the analysis of 91 systems that have been proposed during the last decade. Thus, function, mobility, and usability criteria are defined and explicitly discussed to highlight SEG design guidelines. Additionally, this study provides a detailed description of each system that was analysed including application, functional task, palm design, actuation type, assistance mode, degrees of freedom (DOF), target fingers, motions, material, weight, force, pressure (only for fluids), control strategy, and assessment. Such characteristics have been reported according to specific design methodologies and operating principles. Technological trends are contemplated in this contribution with emphasis on SEG design opportunity areas. In this review, suggestions, limitations, and implications are also discussed in order to enhance future SEG developments aimed at stroke survivors or people with hand disabilities.

Scientometric and Patentometric Analysis to Determine the Knowledge Landscape in Innovation Technologies: The Therapeutic Ultrasound Equipments

LUIS ADRIAN ZUÑIGA AVILES Aguilar-Juárez Verónica MIGUEL ANGEL SANCHEZ COLIN (2020)

En este artículo se propone un modelo de información para determinar el panorama de las tecnologías emergentes relacionadas con los equipos de terapia de ultrasonido, el cual permite la identificación de cuatro grandes categorías en el área de la investigación y el desarrollo dentro del campo, utilizando una metodología competitiva que incorpora la evaluación de publicaciones científicas y un análisis de patentes; utilizando distintas bases de datos mediante la agrupación por palabras clave y cronología. Se examinaron las bases de datos de Google Académico, Scopus, Springer, Sage Journals, ScienceDirect y Academic.edu para consultar artículos y publicaciones científicas; se encontraron alrededor de 67,000 artículos de los cuales únicamente 119 cumplen con los criterios de exclusión, en donde se analizó cómo está conformado un equipo de ultrasonido, sus distintas aplicaciones y nuevas tendencias desde un enfoque de interfaz humano computadora. Las bases de datos utilizadas para la recolección de las patentes fueron Patentscope, Google Patents, e Invenes, así como las bases de WIPO y USPTO; en las cuales se encontraron alrededor 421 patentes con relación a los equipos de ultrasonido, los países en los que se registró la patente y la forma en la que la clasifican. Finalmente, sólo 16 patentes cumplen con los criterios de exclusión. Los resultados indican que Estados Unidos es la nación con más difusión tanto en la publicación de artículos como en patentes.

This paper proposes an information model to determine the panorama of emerging technologies related to ultrasound equipment, which allows the identification of four main categories of research and development within the field, using a competitive methodology that incorporates the evaluation of scientific publications and a patent analysis; by using different databases by keywords clustering and years relevance. Google Scholar, Scopus, Springer, Sage Journals, ScienceDirect and Academic.edu databases were examined to consult articles and scientific publications; about 67,000 articles were found, of which only 119 met the exclusion criteria, the different parts of an ultrasound equipment, its different applications and new trends were analysed. The databases of Patentscope, Google Patents, and Invenes, as well as the bases of WIPO and USPTO were used for the recollection of patents; in which about 421 patents were found in relation to ultrasound equipment, the country in which the patent was registered and the way it is classified. Finally, only 16 patents meet the exclusion criteria. The results show USA as the country with the most diffusion rate in publishing articles and patents.

Internal ballistics of polygonal and grooved barrels: A comparative study

LUIS ADRIAN ZUÑIGA AVILES USIEL SANDINO SILVA RIVERA ADRIANA HERLINDA VILCHIS GONZALEZ PEDRO ALEJANDRO TAMAYO MEZA WILBERT DAVID WONG ANGEL (2021)

As a parameter important ballistic, the research about polygonal and grooved barrels’ behavior has not been widely carried out. The pressures, velocities, stresses, deformations, and strains generated by the firing of 9 mm × 19 mm ammunition in weapons with polygonal barrels are analyzed numerically and experimentally, compared with those generated in pistols with grooved barrels. The Finite Element Method with equal boundary and loading conditions was used in both types of guns, specifying the actual materials of the projectile and the barrels. Subsequently, experimental tests were carried out on various weapons with 9 mm ammunitions of 115, 122, and 124 gr. The results show that the 9 mm bullet fired in a polygonal barrel undergoes a maximum deformation towards its exterior of 0.178 mm and interior of 0.158 mm, with stress up to 295.85 MPa. Compared with 0.025 mm maximum external deformation and 0.112 mm internal deformation of 9 mm projectiles fired in a grooved barrel, with stress up to 269.79 MPa. The deformation in the polygonal barrel is in a greater area, but the rifling impression left is less deep, making its identification more difficult. Although there are differences in the stresses and strains obtained, similar velocity and pressure parameters are achieved in the two types of barrels. This has application in the development and standardization of new kinds of barrels and weapons.
