“…The gait performance of each study participant using the traditional lower-limb orthosis and the knee robotic orthosis was measured and compared. Kinematic gait parameters were measured in the laboratory by utilizing a 12-camera motion capture system (Vicon Nexus, Oxford Metrics) 14 . The study participants were instructed to perform a random sequence of walking trials with 1) the existing lock knee orthosis and 2) the knee robotic orthosis.…”

“…The Vicon system adopted in the gait analysis session of this study was composed of a 12-camera motion capture system (Vicon Nexus, Oxford Metrics) that was used to capture the kinematic gait pattern of the participants. Forty reflective markers were attached to each participant, and the obtained gait data were computed on the basis of the Plug-in-Gait model of the Vicon system 14 . The participants could have about six strides on each walking trial with the walkway for capturing the gait data by the Vicon system in the gait laboratory.…”

IntroductionPoliomyelitis has been considered a statutory notifiable infectious disease in Hong Kong since 1948. Approximately 15% to 80% of patients suffer from post-polio syndrome (PPS) with an increased risk of falling and chronic pain. Most of them relied on the use of knee lock-type orthoses as aids. This study aimed to evaluate the effect of using a custom-fit knee robotic orthosis on their gait performance.Materials and MethodsA case series report was used for this study on a group of individuals suffering from chronic PPS who used orthoses and had a history of falling. A knee robotic orthosis was custom-fit for eight sessions of walking practice. Assessments included laboratory gait analysis, functional measures, and subjective ratings of exertional level. Pain responses were recorded to evaluate the effect of using the knee robotic orthosis on participants’ gait performance.ResultsFive participants completed the study in using the knee robotic orthosis. All achieved reduction in shoulder tilting and trunk swaying movement on walking at the anterior-posterior and the medial-lateral direction. A total of 80% of the study participants achieved reduction in trunk rotation movement, lower-limb circumduction, and hip hiking movement on the affected side on walking. All study participants were able to demonstrate improvement in their gait symmetry after using the knee robotic orthosis as reflected by the symmetric index improvement of kinematics. The rate of perceived exertion and the visual analog scale of pain in all study participants were reported lower when they used the knee robotic orthosis. However, the 10-m walking time achieved was longer.ConclusionsThe knee robotic orthosis had a positive effect on remediating the abnormal kinematics of PPS patients using conventional lock-knee orthosis after eight sessions of training practice. Reduction in the limping gait pattern and improvement in gait symmetry was achieved in using a knee robotic orthosis for walking. The chronic pain response and the physical exertional level on walking were also reduced. However, the walking speed achieved was slower.Clinical RelevanceThe application of the knee robotic orthosis for walking assist is new to most of the PPS patients. The positive outcomes achieved merit further research for future clinical practice.

“…Frecuentemente estas tecnologías son usadas junto con otros desarrollos como sistemas de realidad virtual o aumentada y dispositivos portables (wearables). Entre sus principales aplicaciones se encuentran los análisis biomecánicos, estudios clínicos [17], rehabilitación, animación multimedia para producciones audiovisuales y rendimiento deportivo. Las tecnologías para el análisis de movimiento se dividen a su vez, de acuerdo al tipo de dispositivo que usen para medir el desplazamiento y la ubicación de las articulaciones.…”

El movimiento humano ha sido sujeto de numerosas investigaciones, principalmente en las ciencias biomédicas, ciencias del deporte y animación 3D. Dada la gran cantidad de tecnologías disponibles en el mercado, surge la necesidad de realizar una vigilancia tecnológica que determine sus principales ventajas y limitaciones, aplicaciones y situación actual de Colombia en cuanto a estudios que involucren este tipo de tecnologías. Para lograrlo, se realizó una revisión sistemática de literatura científica a nivel global, siguiendo los parámetros de las metodologías PRISMA y PRISMA P-2015. Se encontró que las tecnologías cinemáticas de análisis de movimiento se dividen en ópticos, inerciales y magnéticos, dónde los sistemas ópticos reportan el mayor número de publicaciones, siendo la tecnología Vicon la más utilizada, debido al gran abanico de aplicaciones que presenta. En cuanto a Colombia, se evidencia poca participación en estos estudios, por lo que se debe fortalecer esta competencia tanto a nivel académico como empresarial.
