Aplicación de apoyo para la rehabilitación de niños con parálisis cerebralChumpitaz Avendano, Max; Santiago Almeyda, Jéssica; Martell Luya, Kevin (Universidad Peruana de Ciencias Aplicadas (UPC), 2016-07-01)In Peru, the Instituto Nacional de Rehabilitación (INR) is one of the centers that treats people with disabilities. In 2013, 49.88% of its attended patients had ages between 0 and 9 years, and 0.81% from 18 092 patients have been diagnosed as children with Cerebral Palsy (CP). Given such demand and despite the efforts to solve this problem, access to a number of analyses to treat this disability is hindered, particularly, the knee kinematics analysis of children with CP, which is the subject of our research. To perform this analysis, the INR uses its gait laboratory; the problem is that it requires complex equipment, a big budget, and highly-trained personnel. This study proposes a tool, implemented in a gait reeducation center, that allows to quantify the measurement of angles of the kinematic analysis of the knee, based on Image Processing and Kinect, which is a device for simple, portable and economical use.The characteristics of this application have been raised with the support of Ítala Zegarra, physical therapy specialist, who laid the foundation for its development. Likewise, the reports of the patients' progress, obtained from the application, were established with the help of a team of specialists in physiotherapy led by Ítala Zegarra.For the validation of the tool’s accuracy, one subject with normal gait has been evaluated in terms of kinematic analysis of the knee. The analysis was simultaneously developed between the Vicon System, 3D gold-standard in the market, and the present tool, 2D system, over the same patient. The measurement results were very similar between both systems, obtaining a R2 of 0.93, approximate value to those obtained by the Vicon system. Later, the tool was applied in children with Cerebral Palsy, proving that it helps to increase the accessibility of its treatment. In conclusion, Kinect is a low cost alternative for capturing knee angles of children with CP, which offers a 2D kinematics analysis.Acceso abierto
