Stroke is currently the world’s second cause of disability. It can cause deficits such as postural control, and telerehabilitation could improve the therapeutic dose as well as functional results. The aim of this work is to determine the effectiveness and usability of a low-cost telerehabilitation system in patients with stroke. We developed a telerehabilitation system based on exergames on smartphones, inertial sensors, and a cloud database. We trained the balance of six participants (three men and three women) in early subacute stroke (seven weeks of progress). In addition to their conventional treatment, these participants trained for a total of nine sessions of 30 min per week, for four weeks. The telerehabilitation group was compared with a control group of four clinically similar participants (three men and one woman). Clinical and usability measurements were made before and after the training. The results show a significant improvement of 11.3 ± 3.5 points in the Berg Balance Scale, 8.3 ± 3.01 points in the Mini-BESTest, and 17.5 ± 9.87 points in the Barthel scale for the telerehabilitation group. However, only the improvements of Berg and Barthel scales were statistically higher for the telerehabilitation group compared to the control group. The proposed system achieved excellent usability on the System Usability Scale (87.5 ± 11.61). Our results demonstrate that a complementary low-cost telemedicine approach is feasible, and that it can significantly improve the balance of stroke patients; therefore, the proposed clinical strategy could potentially improve dosage and overall treatment effectiveness.

En este trabajo se analizan los diferentes patrones de especialización productiva que han seguido inversionistas extranjeros en la industria del vino en Chile; en particular, el efecto de la estructura de propiedad que la firma escoge para su nuevo negocio vitivinícola. Existe evidencia que viñas organizadas como joint venture (JV) tienen mayor participación en los segmentos de vinos exportados con mayor valor unitario que las viñas que son filiales de inversionistas extranjeros. La hipótesis central bajo estudio es que para inversionistas extranjeros con producción más especializada en vinos de mayor R. JAVIER BUSTOS.
