As life expectancy continues to increase, the inevitable weakening and rupture of bone tissue have grown as concerns in medical community, thus leading need for adhesive materials suitable repair applications. However, current commercially available adhesives face certain drawbacks that prevent proper repair, such low biocompatibility, poor adhesion wet surfaces, high polymerization temperatures. This work aims develop an injectable photo-responsive chitosan methacrylate/graphene oxide...
Introduction: Management strategies for stage II tibialis posterior tendon dysfunction are centered on transfers and osteotomies. One of the most commonly used is flexor digitorum longus (FDL) to navicular, but its superiority over other locations or tendons, along with role spring ligament have not been objectively evaluated. Aims: We aimed quantify both location magnitude secondary stresses that develop as a consequence initial pathology. Methods: In this study, we computational model...
Abstract Background Gait distortion is the first clinical manifestation of many pathological disorders. Traditionally, gait laboratory has been only available tool for supporting both diagnosis and prognosis, but under limitation that any interpretation depends completely on physician expertise. This work presents a novel human model which fusions two important information sources: an estimated Center Gravity (CoG) trajectory learned heel paths, by means allowing to reproduce kinematic...
Background:Most inhabitants in Latin America are concentrated large urban foci with different access to facilities. Although the main hospitals offer specialized services, economically vulnerable populations cannot easily afford these pediatric population being most affected. This article presents design and implementation of a low cost telepediatric system, applied primary care through study Bogotá, Colombia, mainly aimed reduce number unnecessary transfers commonly sent medical services....
Adult-Acquired Flatfoot Deformity (AAFD) is a progressive orthopedic condition causing the collapse of foot's medial longitudinal arch, often linked with injuries to plantar arch's passive stabilizers, such as spring ligament (SL) and fascia. Conventional treatment typically involves replacing SL synthetic material grafts, which, while providing mechanical support, lack biological compatibility native ligaments. In response this shortcoming, our study developed an electrospun, twisted...
<p>La marcha humana es el resultado de la compleja interacción entre varios subsistemas: neuromuscular, músculo-tendinoso y osteoarticular, que trabajan coordinadamente para generan dinámica corporal necesaria desplazamiento bípedo. En rutina clínica, estudio base identificación trastornos patológicos, facilitando su diagnóstico, tratamiento seguimiento. Tradicionalmente este análisis determina conjunto patrones describen del sistema. Sin embargo, éste insuficiente evaluar algunos...
Most of the mechanical prostheses available do not have many important characteristics foot, such as flexibility, mobility and ability to adapt any type terrain. Furthermore, it is an artificial extension, people sensory control over terrain adaptation depends entirely on design prosthesis. This document proposes a transtibial prosthesis capable adapting uneven that will provide user with feedback when slope detected. The proposed based state-of-the-art functional models are shape human...
The Default Mode Network (DMN) is a resting state network widely used for the analysis and diagnosis of mental disorders. It normally detected in fMRI data, but its detection data corrupted by motion artefacts or low neuronal activity, use robust method mandatory. In it has been shown that signal-to-noise ratio (SNR) sensitivity regions increased with di erent smoothing kernels sizes. Here we propose to multiscale decomposition based linear scale-space representation DMN. Three main points...
The use of computational models the human foot based on finite element analysis offers a promising alternative for understanding biomechanical internal changes this structure. However, evaluation dynamic scenarios has been challenging. This research aims to design model that accurately simulates biomechanics during stance period gait cycle in healthy and flatfoot scenarios. is focused analyzing stress variations soft tissues such as plantar fascia spring ligament provide valuable insights...
In Colombia, approximately more than 500.000 people have disabling hearing loss, representing around 1% of the population in and only 400 professional interpreters Colombian Sign Language (LSC) are available whole country. this data descriptor, we present a dataset with recordings as an important effort to develop technologies that facilitate social inclusion equity for deaf community Colombia. This includes multimodal native non-native signers signing different elements LSC lexicon....

<title>Abstract</title> The use of computational models the human foot based on finite element analysis (FEM) offers a promising avenue for understanding biomechanical internal changes this structure. Bone and soft tissues have been modeled. However, reported in literature often lack comprehensive representation foot's dynamic. This research aims to overcome these limitations by designing model that accurately simulates biomechanics during stance period gait healthy flatfoot scenarios. is...
Adult-acquired flatfoot has been considered to arise from tibialis posterior tendon deficiency. Recent evidence shows that arch stability is mainly maintained by structures such as plantar fascia and spring ligament. The dysfunction of these ’passive’ stabilizers results in loss integrity causes forefoot pronation reactive overload, especially the peroneus longus tendon. (PLT) spans several midfoot joints overloads with lengthening. biomechanical stress/changes occurs this are not well...
The posture instability and body balance alteration, are signs commonly observed in patients with diseases associated the musculoskeletal, visual, vestibular proprioceptive systems, being stabilometry main clinical assessment study. However, it has not been established a standard or quantitative pattern to classify healthy pathological subjects based on impaired level. Objective: objective of this study was conduct preliminary stabilometric analysis 38 (19 women 19 men) order identify...
Medializing calcaneal osteotomy (MCO) is a flatfoot treatment in stages IIa–IIb. It true that structural correction well known, but stress changes foot tissues have not been sufficiently studied to date. Our objective was evaluate the generated by MCO both hindfoot and forefoot bones some soft support arch. A finite element model employed, simulating situations related development. Results show higher concentration around region when used patients with plantar fascia weakness. Additionally,...
