“…To promote greater adoption, usability, and safety in the use of an exoskeleton, one must consider physical and biological parameters aiming at a better HMI (Zorkot et al, 2022 ). For this, after the development of the G-Exos, experiments were carried out with volunteers with foot drop, analyzing the following parameters: functionality and usability, accuracy of the onboard system for identifying the gait phases, gait speed, and range of motion of dorsiflexion, eversion/inversion of the ankle, comparing with and without the use of the G-Exos.…”

Stroke is the second leading cause of death and one of the leading causes of disability in the world. According to the World Health Organization, 11 million people suffer a stroke yearly. The cost of the disease is exorbitant, and the most widely used treatment is conventional physiotherapy. Therefore, assistive technology emerges to optimize rehabilitation and functional capabilities, but cost, robustness, usability, and long-term results still restrict the technology selection. This work aimed to develop a low-cost ankle orthosis, the G-Exos, a wearable exoskeleton to increase motor capability by assisting dorsiflexion, plantarflexion, and ankle stability. A hybrid system provided near-natural gait movements using active, motor, and passive assistance, elastic band. The system was validated with 10 volunteers with foot drop: seven with stroke, two with incomplete spinal cord injury (SCI), and one with acute inflammatory transverse myelitis (ATM). The G-Exos showed assistive functionality for gait movement. A Friedman test showed a significant difference in dorsiflexion amplitude with the use of the G-Exos compared to gait without the use of the G-Exos [x2(3) = 98.56, p < 0.001]. In addition, there was also a significant difference in ankle eversion and inversion comparing walking with and without the G-Exos [x2(3) = 36.12, p < 0.001]. The G-Exos is a robust, lightweight, and flexible assistive technology device to detect the gait phase accurately and provide better human-machine interaction. G-Exos training improved capability to deal with gait disorders, usability, and motor and functional recovery. Wearable assistive technologies lead to a better quality of life and contribute using in activities of daily living.

Este documento muestra un análisis de los resultados de búsqueda de literatura sobre sistemas tecnológicos de apoyo a personas víctimas de diversos eventos que implican perdida de movilidad en algún grado, requiriendo de desarrollos como la robótica asistencial. Se usa la guía PRISMA 2020 como referente de la revisión sistemática. Se consultó en la base de datos Scopus publicaciones sobre robótica y víctimas de la violencia de los últimos tres años, se construyeron redes bibliométricas con Vosviewer, se filtraron los resultados, se caracterizaron y se agruparon por la atención a víctimas tras desastres y enfermedades. Se concluye, es necesario encaminar los esfuerzos en robótica hacia la atención de víctimas de la violencia en Colombia apoyado en los avances identificados documentados a nivel científico dada la ausencia de evidencia al respecto.
